I'm trying to created a select box in my form and display the image that is selected in the select box next to it. I know it requires jquery or something and I have no clue when it comes to that. If anyone can help or point me in the right direction that would be awesome!!!
<table width="100%">
<tr>
<td>
<select id="icon" name="icon" class="form-control select2">
<?php foreach ($icons as $icon) { ?>
<option value="<?php echo $icon['link']; ?>">
<?php echo $icon['name']; ?>
</option>
<?php } ?>
</select>
</td>
<td align="center" id="iconPreview">
Image Here
</td>
</tr>
</table>
i found this jquery snippet but it doesn't display anything on change...
JQuery:
<script>
$(document).ready(function() {
$("#icon").change(function() {
$("#iconPreview").empty();
if ( $("#icon").val()!="" ){
$("#iconPreview").append("<img src=\"" + $("#icon").val() + "\" />");
}
else{
$("#iconPreview").append("displays image here");
}
});
});
</script>
You'll need to add jQuery if you want to use jQuery in the head, so in your document in the <head> add this line:
<script src="http://code.jquery.com/jquery-1.12.0.min.js"></script>
Then give the TD you want the image in a class:
<td class="imageHere" align="center" id="seleced_image">
Then, at the bottom of your page (or a .js page if you want to link it) add this:
<script>
$(function(){
$('#icon').change(function(){
var image = $('#icon').val();
$('#seleced_image').html("<img src='" + image + "' alt='description' />");
});
});
</script>
This jQuery is saying "Everytime the #icon dropdown changes, load the image into the <td>
This is the simplest way to do it without learning any jQuery. Otherwise, I suggest you learn jQuery or better yet, javascript.

Its better to work with IDs than classes on cases like this.

I have a table which I has links on each row. I am trying to use AJAX to retrieve an array of data from the database via PHP and return the data which will print in another DIV.
I am trying to get the attribute value (link ID) that I assign to each row and pass this value to the query. I am not able to get the link ID, it does not display when I test issuing an alert. I read several post and tried a few things but no good. The alert popup displays "undefined".
<tr id="mashed_row">
<td class="linked-title dark unpadded">
<?php echo $link['keywords']; ?>
</td></tr>
<script type="text/javascript">
$(document).ready(function(){
$('#mashed_row a').click(function () {
alert($(this).closest('tr').find('td').attr('link_id'));
});
});
</script>
You are trying to get td attr which is not there, try this, hope it helps :-
$(document).ready(function(){
$('#mashed_row a').click(function () {
alert($(this).attr('link_id'));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<table>
<tr id="mashed_row">
<td class="linked-title dark unpadded">
key words
</td>
</tr>
<table>
Simply use $(this).attr('link_id')
$(document).ready(function(){
$('#mashed_row a').click(function () {
alert($(this).attr('link_id'));
});
});
Your TD does not have a link_id attribute, your <a> has it. I've created an example showing both versions:
$(document).ready(function(){
$('#mashed_row a').click(function () {
console.log("TD:", $(this).closest('tr').find('td').attr('link_id'));
console.log("A:", $(this).closest('tr').find('a').attr('link_id'));
// or if you really want to get the attribute from the clicked item, it's even easier:
console.log("direct:", $(this).attr('link_id'));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<table>
<tr id="mashed_row">
<td class="linked-title dark unpadded" link_id="link_id_TD">
Hello

</tr>

jQuery Dialogue box is not working properly for dynamic data from database. I want to open dialogue box for multiple data fetched from database. But the problem is that when I click any of the link to open particular dialogue box for particular id of database table record but it opens all the previous id's dialogue boxes also.
For example if I click on id 2 dialogue box it opens 1 and dialogue boxes simultaneously. I want some download in dialogue box also.
jQuery code:
$(document).ready(function() {
$(function() {
$(".dialog").dialog({
autoOpen: false,
maxWidth:600,
maxHeight: 500,
width: 600,
height: 300,
dialogClass: 'main-dialog-class',
modal: true
});
$("a.To").on("click", function() {
$(".dialog").dialog("open");
});
});
PHP code:
<table>
<?php foreach($tList as $ts) : ?>
<div class="dialog" title="Dialog Form">
<?php
$sql1="select * from table where ID='".$ts["ID"]."'" ;
$result1=mysqli_query($link,$sql1);
while($rows=mysqli_fetch_array($result1)){
echo $rows["t1"];
?>
<?php echo $rows['Name'];?><br/>
<?php
}
?>
</div>
<tr>
<td style="display:none">
<?php echo $ts["ID"]; ?>
</td>
<td>
<a href="#" class="To" >
<?php echo $ts["Title"]; ?></a>
</td>
<td>
<?php echo $ts["t1"]; ?>
</td>
<td>
<?php echo $ts["t2"]; ?>
</td>
</tr>
</table>
For starters, your HTML looks like you are nesting the dialog box in a <div> inside the table, but not in a cell (that should be an error in the browser).
But in your javascript, you need a way to specifically identify each dialog box. The error you are reporting makes sense; by choosing $('.dialog'), you are saying "pick every element on the page with a classname "dialog".
I think the easiest way is to change your JavaScript to:
$("a.To").on("click", function() {
$(this).find(".dialog").dialog("open");
});
and then move the dialog box into a cell in each row in your PHP.
Otherwise, you may choose a unique identifier for each dialog box, and rename them to an id, not a class.
EDIT
Yes, you can add the unique id in PHP for the selectors, add the same id in data and then find them with a jQuery selector.
In your PHP:
<td>
<a href="#" class="To" data-dialogfinder='<?php echo $ts["ID"]; ?>'>
<?php echo $ts["Title"]; ?>
</a>
</td>
Then, in you jQuery:
$("a.To").on("click", function() {
var diabox='#'+$(this).data("dialogfinder");
$(diabox).dialog("open");
});
I don't know if that is the full code, but in what you have posted you have missing the endforeach; (to close the foreach() : opened at the beginning).
I'm building a website where the admin can make settings for the website. I would like the admin settings page to have a similar "feel" as the rest of the website, which has some nice looking jQuery features.
On the admin site there's a hidden div, which is shown when one of six links has been clicked. I'd like the content of the hidden div to change content before showing itself. I'm not sure how to do this. I could have a div box for every link on the page. But this becomes pretty cumbersome since I'd need to repeat my css and jquery for every link. I imagine that this, somehow, can be done with some javascript/jquery code that determines which link that was click and then decides which php function to call inside the hidden div. Then the php could "echo" out the content of the div, which then could be shown.
How could one do this?
My HTML/jQuery code is as follows:
--- The html links ---
<table id="settings">
<tr>
<td>
<img src="images/folder.gif" alt="" height="100"/>
</td>
<td>
<img src="images/folder.gif" alt="" height="100"/>
</td>
<td>
<img src="images/folder.gif" alt="" height="100"/>
</td>
----- The Hidden div -----
<div id="dashboard_box">
<div class="dashboard_inside">
<form action="#" method="post">
<p style="font-size:20px; font-weight: bold;">Change color</p>
</br>
<fieldset>
<? load_content1();?>
</fieldset>
</form>
</div>
</div>
---- jquery code (working)----
var mouse_is_inside = false;
$(document).ready(function() {
$(".action").click(function() {
var loginBox = $("#dashboard_box");
if (loginBox.is(":visible"))
loginBox.fadeOut("fast");
else
loginBox.fadeIn("fast");
return false;
});
$("#dashboard_box").hover(function(){
mouse_is_inside=true;
}, function(){
mouse_is_inside=false;
});
$("body").click(function(){
if(! mouse_is_inside) $("#dashboard_box").fadeOut("fast");
});
});
You probably want to use ajax to load the content from the server. Take a look at jquery's .load() method: http://api.jquery.com/load/
You could include a data attribute per link:
<a class="action" data-content="content.php?method=load_content1"></a>
<a class="action" data-content="content.php?method=load_content2"></a>
js would look something like this:
$(".action").on('click', function() {
$("#dashboard_box fieldset").load($(this).data('content'), function() {
var loginBox = $("#dashboard_box");
if (loginBox.is(":visible"))
loginBox.fadeOut("fast");
else
loginBox.fadeIn("fast");
}
return false;
});
Then, in your content.php file you could check the method parameter in the url to determine what content to return.
My php is a little rusty, but something like this:
<?
call_user_func($_GET['method']); // i'm not sure how safe this is. you may want to be more explicit
?>
You can just add data attribute in each of your link's
<a href="#" data-url="content1.php" ..
Then on click of any of the a you can get the php to be called.
$('a').on('click',function(){
var phpFunctionToCall = $(this).data('url');
});
You probably need to make ajax call to load content into your fieldset As this <? load_content1();?> run's on server and javascript have no control over it.
Thanks for all the help. this is what I ended up doing.
--- HTML ---
<a class="action" data-content="content.php?method=load_content2"></a>
---Jquery---
var mouse_is_inside = false;
$(document).ready(function() {
$(".action").click(function() {
var phpFunctionToCall = $(this).data('content');
$('#indhold').load(phpFunctionToCall);
var loginBox = $("#dashboard_box");
if (loginBox.is(":visible"))
loginBox.fadeOut("fast");
else
loginBox.fadeIn("fast");
return false;
});
$("#dashboard_box").hover(function(){
mouse_is_inside=true;
}, function(){
mouse_is_inside=false;
});
$("body").click(function(){
if(! mouse_is_inside) $("#dashboard_box").fadeOut("fast");
});
});
--- PHP (shortened)---
function load_settings_panel($settingOnRequest) {
return $settingOnRequest;
}
$result = call_user_func('load_settings_panel', $_GET['method']);
echo($result);
I know very well that this question is ask many time but some how my problem is different and i didn't find the solution.
Now comes on issue.
I have a an image,so whenever i click on to the image the pop up window is open and show the data.now i want to make this dynamic and wants that the data should be come according to the id.
here is my image code.:
<div id='contact-form'>
</div>
<!-- preload the images -->
<div style='display:none'>
<img src='<?php echo base_url();?>assets/images/img/contact/loading.gif' alt='' />
</div>
And on its click the ajax is called from js file here is the code of that js file:
//here the provider is controller and show_coupon_pre is a function which call the view having the data.
$.get("provider/show_coupon_pre", function(data){
// create a modal dialog with the data
$(data).modal({
closeHTML: "<a href='#' title='Close' class='modal-close'>x</a>",
position: ["15%",],
overlayId: 'contact-overlay',
containerId: 'contact-container',
onOpen: contact.open,
onShow: contact.show,
onClose: contact.close
});
});
I have a table having no of records and each record having this type of image.where the user can click and get the preview in pop window.
But i want to show the data in pop up according to the row like for id=1 it should be show the data of id==1 and so on. now can you you guys please help me how can i pass this id to the js file by which i can fetch the required data.
I am working in codeignitor.
Simplest solution
<table>
<tr>
<td><img class="banner" src="/image1.png" post_id="1"></td>
<td>some other data 1</td>
</tr>
<tr>
<td>
<td><img class="banner" src="/image1.png" post_id="2"></td>
<td>some other data 2</td>
</tr>
</table>
Javascript:
$('.banner').click(function() {
post_id = $(this).attr("post_id");
// send your ajax with post_id
} );
If you have the ID in php when outputting the image, I would do this:
<script>
var randomId = <?php echo '"' . $phpId . '"'; ?>
</script>
When you open the application can you please click on the "Add Question" twice so it adds 2 table rows.
Now you will see in the application that above the horizontal line there is a textarea and a plus button, and below the horizontal line shows 2 table rows, both rows displaying its own textarea and plus button.
Now my question is that I want these 2 outcomes to happen but I do need help from somebody who is good at using Jquery/Javascript in order to solve this situation:
Situation 1. If the user clicks on the plus button ABOVE the horizontal line, then it displays a modal window which contains a search bar, Please type in search bar "AAA". You will now see a list of results. Now what I want is that if the user selects a row by clicking on the "Add" button, then I want the "QuestionContnet" within that row to be displayed in the textarea above the horizontal line. At the moment the Add button just closes the modal window but doesn't add anything into the textarea.
Situation 2: This deals with the user clicking on a plus button within one of the table rows BELOW the horizontal line. I want the same thing to happen except the "QuestionContent" added is displayed in the textarea within the same row the user has clicked the plus button, no where else.
How can both situations be solved so that it adds the QuestionContent into the correct textareas depending on which plus button is clicked? I am using an Iframe to display the content within the modal window.
UPDATE:
If you look at the application, it is now displaying "[Object] [object]" in textaea when I click "Add" button. Not the "Question".
Below is the code for the application:
<head>
<script type="text/javascript">
var plusbutton_clicked;
function insertQuestion(form) {
var $tbody = $('#qandatbl > tbody');
var $tr = $("<tr class='optionAndAnswer' align='center'></tr>");
var $plusrow = $("<td class='plusrow'></td>");
var $question = $("<td class='question'></td>");
$('.questionTextArea').each( function() {
var $this = $(this);
var $questionText = $("<textarea class='textAreaQuestion'></textarea>").attr('name',$this.attr('name')+"[]")
.attr('value',$this.val());
$question.append($questionText);
});
$('.plusimage').each( function() {
var $this = $(this);
var $plusimagerow = $("<a onclick='return plusbutton();'><img src='Images/plussign.jpg' width='30' height='30' alt='Look Up Previous Question' class='imageplus'/></a>").attr('name',$this.attr('name')+"[]")
.attr('value',$this.val());
$plusrow.append($plusimagerow);
});
$tr.append($plusrow);
$tr.append($question);
$tbody.append($tr);
form.questionText.value = "";
$('.questionTextArea').val('');
}
function plusbutton() {
// Display an external page using an iframe
var src = "previousquestions.php";
$.modal('<iframe src="' + src + '" style="border:0;width:100%;height:100%;">');
return false;
}
function closewindow() {
$.modal.close();
return false;
}
$('.plusimage').live('click', function() {
plusbutton($(this));
});
function plusbutton(plus_id) {
// Set global info
plusbutton_clicked = plus_id;
// Display an external page using an iframe
var src = "previousquestions.php";
$.modal('<iframe src="' + src + '" style="border:0;width:100%;height:100%;">');
return false;
}
function addwindow(questionText) {
if(window.console) console.log();
var txt = $(this).val(questionText);
if($(plusbutton_clicked).attr('id')=='mainPlusbutton') {
$('#mainTextarea').val(txt);
} else {
$(plusbutton_clicked).parent('td').next('td.question').find('textarea.textAreaQuestion').val(txt);
}
$.modal.close();
return false;
}
</script>
</head>
<body>
<form id="QandA" action="<?php echo htmlentities($action); ?>" method="post">
<div id="detailsBlock">
<table id="question">

</table>
</div>
</form>
</body>
The details stored in the modal window comes from a seperate script known as "previousquestions.php", Below is the code where it shows the result of the "QuestionContent" field only displayed and it's "Add" button after the user has compiled a search:
<?php
$output = "";
while ($questionrow = mysql_fetch_assoc($questionresult)) {
$output .= "
<table>
<tr>
<td class='addtd'><button type='button' class='add' onclick='parent.addwindow();'>Add</button></td>
</tr>";
}
$output .= " </table>";
echo $output;
?>
Thank you
Application here
The first issue is this ->
<button id="add">
You cannot reuse an ID over and over, or, the page will iterate to the last element with that ID and NEVER run anything on any previous elements.
Quick fix:
<button class="add">
Simple enough.
We need to get the question text, from the first column, there are so many methods to do this with jQuery selectors it's mind blowing.
Situation 1
Let's take a peek at one option ->
$(document).on('click', '.add', function(){
//now that we've declared the click function, let's jump up to our parent element, and grab the text in the first cell.
var theQuestion = $("td:first-child", $(this).parent()).text();
//Now that we've figured out how to traverse the DOM to get the data we want, we need to move that data elsewhere.
$('.questionTextArea').val(firstCell);
});
Simple enough, right? That should solve the first problem you had.
Note: Textareas use value to set the data, whereas other elements will use .text()
Situation 2
Alright, now we need to figure out how to add a unique identifier to the "+" row when we click, and check for that "unique identifier" when appending the data, let's do it.
You have a <td> with a class of plusrow, sounds good, let's make a click function out of it, and give it a cool new class to reference.
$(document).on('click', '.plusrow', function(){
//adding a unique class for the purpose of the click.
$(this).addClass('activePlusRow');
});
So now the "+" we clicked has a new class -- activePlusRow, let's go back to our initial click handler for the add button, and give it some new conditional statements.
$(document).on('click', '.add', function(){
//lets get our Question Text...
var theQuestion = $("td:first-child", $(this).parent()).text();
//the row is present, let's then make sure that the proper cell gets your data.
if($('.activePlusRow').length > 0){
$('.activePlusRow').next('.textAreaQuestion').val(theQuestion);
$('.activePlusRow').removeClass('activePlusRow');
}
});
Alright, as you can see of the above, we test to see if the activePlusRow class exists, if it does, then we iterate to the next textarea with a class of textAreaQuestion and change the value of it, to theQuestion from the .add button we clicked.
Let me know if you've any questions.
I think best way to target chosen question to specified textarea is to parameterise your plusbutton function:
function plusbutton(plus_id) {
// Set global info
plusbutton_clicked = plus_id;
// Display an external page using an iframe
var src = "previousquestions.php";
$.modal('<iframe src="' + src + '" style="border:0;width:100%;height:100%;">');
return false;
}
Of course you have to declare global var plusbutton_clicked; before insertQuestion function so other functions could change/use this information. You have to call this function with unique parameter for each plusbutton (you generate it dynamically, so this is up to you how you want to do it)
Then you can simply use it in your $(document).on('click', '.add', function(){}); - when user clicks 'add' button you have your plusbutton id so you can navigate with jQuery to corresponding textarea and place text there.
I'm thinking next() isn't the right function, since it only searches for the immediately following sibling... Try this:
$(document).on('click', '.add', function(){
console.log("clicked");
//lets get our Question Text...
var theQuestion = $("td:first-child", $(this).parent()).text();
//the row is present, let's then make sure that the proper cell gets oru data.
if($('.activePlusRow').length > 0){
$('.activePlusRow').next('.question').find('textarea.textAreaQuestion').val(theQuestion);
$('.activePlusRow').removeClass('activePlusRow');
}
$.modal.close();
return true;
});
