I have the following table dynamically generated using php and MySQL. The number of rows and number of buttons generated are dynamic.
<?php
if($resultCheck != 0){
while($result = mysqli_fetch_array($tableQueryExecute)){
$normalShiftDuration = $result['shift1Duration'];
?>
<tr> <form method="post" id="vtagViewTwo">
<td name=""><select class="form-control" name="normalShiftOa" id="normalShiftOa"><option>1</option></select></td>
<td>
<input type="submit" class="btn btn-primary" name="editButton" id="editButton" value="Save">
</td>
</form></tr>
<?php
}
}
?>
I want to get value of the <td> which is normalShiftOa value with the button click using jQuery click event as below.
$("#editButton").click(function(){
alert("Clicked");
});
But since there are many button generating for each row with the same id, I am not able to do it. Does anyone know how to do it? I am able to do it using php $_POST['editButton'] method. But I want to do it using jQuery.
Edit 1
I changed the id editButton to class and tried the following. But it is not working
$(".editButton").click(function(){
alert($(this).$("#normalShiftOa").val());
});
Instead of using ids, use class editButton. Then, if you want to get the value of the select, use jQuery like shown below:
$(".editButton").click(function(){
let tdValue = $(this).closest("form").find("select").val();
});
Edit: Code snippet that works.
$(".editButton").click(function(event){
let tdValue = $(this).closest("form").find("select").val();
alert(tdValue);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<tr> <form method="post" id="vtagViewTwo">
<td name=""><select class="form-control" name="normalShiftOa" id="normalShiftOa"><option>1</option></select></td>
<td>
<input type="submit" class="editButton btn btn-primary" name="editButton" id="editButton" value="Save">
</td>
</form></tr>

I have a tip section that can be "custom" input from a customer. When the customer enters a value, I want to pass it to PHP for updating the order.
I'm unsuccessful and I'm thinking I'm approaching this problem the wrong way since I can't get it to work. What options are available to me without using AJAX?
The tip section:
<?= ($receipt['tip'] > 0 ?
'<tr id="tip-area"><th>Tip</th>
<td><textarea id="tip" name="update_tip" readonly>'. $receipt['tip'].'</textarea></td>
</tr>'
: '') ?>
My form which has different tip options:
<form method="post">
<tr>
<button title="20% Tip" type="submit" name="update_tip" id="update_tip" class="tip-button"
value="<?= ($_SESSION['order']['quote']['subtotal'] * 0.2); ?>">
<small>20%<br><?= number_format(($_SESSION['order']['quote']['subtotal'] * 0.2), 2) ?></small>
</button>
<button title="Edit Tip" type="button" name="update_tip" id="custom-tip" class="tip-button">
<small>Edit<br>Tip<br></small>
</button>
<button title="Save Tip" type="submit" id="save_tip" class="hidden">
<small>Save<br>Tip</small>
</button>
</tr>
</form>
My jQuery:
$('#custom-tip').click(function(){
$('#tip').removeAttr('readonly').focus();
$('.tip-button').addClass("hidden");
$('#save_tip').removeClass("hidden");
});
$('#save_tip').click(function (){
var tip = $('textarea#tip').val();
$('<input type="hidden" name="update_tip" value="' + tip + '">').submit();
});
$('#tip').focus(function(){
this.value = '';
});
When they press "Edit Tip", the readonly property is remove, the area comes into focus and value is cleared.
Then the user should enter a value and hit Save.
Then I'm trying to retrieve the value they entered.
I think this is what you want:
$("form").submit(function() {
$("<input>", {
type: "hidden",
name: "update_tip",
value: $("#tip").val()
}).appendTo($(this));
});
This will create the hidden input with the value from the textarea and append it to the current form when before the form is submitted.
You need to have PHP code on the same page (because your form does not specify an action) that handles the data. Use the 'name' attribute for your input to specify the key of the value you wish to access in the $_POST super global. For example, if I post a form with the following code:
<form method='POST'>
<input type='hidden' value='hello' name='world'>
<input type='submit' value='submit'>
</form>
Then in PHP, I can access the value of the element with the name "world" with the following code:
$_POST['world']
Use this syntax to acquire the data from the form and persist it/update it.
I have a task list.
Initially I display all of them. I want to create 2 buttons s.t. one displays the tasks ordered by date, and the other displays the tasks that have passed.
How can I do this? I don't know how to make a button to do anything else than submit.
I was thinking about redirecting to another "page" but I'm not sure it is efficient.
<button type="button" name = 'display1' value="orderedDisplay">Order by date</button>
<button type="button" name = 'display2' value="passedTasks">Passed tasks</button>
or
<table >
<tr>
Order by date
</tr>
<tr>
Display past events
</tr>
</table>
But I don't know how to "catch" the event of clicking with "button"type button.
In order to have a button doing something, you need some JavaScript, executing that "something":
<input type="button" name='display1'
onclick="callOrderByDate()" value="Order by date"/>
....
<script type="text/javascript">
function callOrderByDate()
{
alert("I'm not ging to write the entire code here...");
}
...
</script>

I am using php for filling some data in below div tag
<div id="div_content">
<?=$text_content?>
</div>
from the below form contents
<form action="javascript:fill_content(parm)">
<table>
<tr>
<td><textarea name='content_name' id='content_id'>This is a test</textarea> </td>
</tr>
</table>
<input name='form_submit' type="submit" value='submit'>
</form>
I used jquery:
<script type="text/javascript">
function fill_content(textarea_content) {
$('#div_content').load('/process.php?content=' + textarea_content);
}
</script>
How can i get textarea value in javascript:fill_content(parm) as parm.
I used document.getElementByID('content_id').value and also document.getElementsByName('content_name')[0] instead of parm, but they did not work.
Many Thanks.
fill_content($("#content_id").val());
Why don't you use jQuery again to address the textarea? U can use $('#div_content').find('#content_id').val()
I have an html table built from a database query which loops through and creates a button for each camera name found and puts them in a table:
<?php
for($i=0;$i<$num_rows;$i++)
{
?>
<tr>
<td>
<input type="submit" class="play" data-hash="<?php echo $result_cameras[$i]["camera_hash"]; ?>" value="<?php echo $result_cameras[$i]["camera_name"]; ?>">
</td>
</tr>
<?php
}
?>
This resolves to something like this:
<tr>
<td>
<input type="submit" class="play" data-hash="0d3d0ac6e54a640c73f1149d4d0bbc38e99d10f5" value="Office Window">
</td>
</tr>
<tr>
<td>
<input type="submit" class="play" data-hash="b824cba374c3d5ab7806ad8260c939323c03147b" value="aaa">
</td>
</tr>
<tr>
<td>
<input type="submit" class="play" data-hash="ec9658f0c1855e2e2ac09ae284f5e6990dbf445d" value="laptop">
</td>
</tr>
Notice the data hash attribute is different for each button. I want to process this button with my jquery code:
$(".play").click(function(){
var camerahash = $('input').data('hash');
console.log($('input').data('hash'));
});
No matter which button I click I will always get the hash from the first button I click: 0d3d0ac6e54a640c73f1149d4d0bbc38e99d10f5. Any help is appreciated.
$('input').data('hash') gives you the data attribute of the first input in the selection use $(this).data('hash') to get the data attribute of the currently clicked input
You need to specify which input element to read.
Try something like:
$(".play").click(function(){
$this = $(this);
var camerahash = $this.data('hash');
console.log($this.data('hash'));
});
You are always calling the first object of .play. This would be a correct way:
$('.play').on('click', function(){
var camerahash = $(this).data('hash');
});
You could always grab them by using the .attr(data-hash) html5 attribute.
Try:
$('.play').on('click', function() {
var _hash = $(this).attr('data-hash');
console.log(_hash);
});
Your selector will return the first one that it comes to. Use this instead
<script>
$("input.play").click(function() {
alert($(this).data('hash'));
});
</script>
I'm somewhat new to jQuery, so I could use some help here.
This is my issue:
I have a PHP script outputting a dynamic table. Each row has an "edit" button, plus some other fields. Only 3 of those need to be turned into an input box. The edit button should only put that specific row into "edit mode." I got as far as assigning each row a unique class by adding a number to the end of it.
I have been able to use jQuery to change all of the rows into edit mode, but I need it to be specific to a row.
An example row would have classes like name0, price0, and desc0. The next row would go on to classes name1, price1, and desc1 (for the fields that need changed). How can I reference these values and pass them to jQuery so it processes an event on just those elements?
There are two ways of doing this:
Dynamically creating the elements when the button is pressed; or
Hiding and showing elements that already exist.
Too much DOM manipulation can be really slow (particularly on certain browsers) so I favour (2). So for example:
<table class="editable">
<tbody>
<tr>
<td>one</td>
<td>
<div class="view">two</div>
<div class="edit"><input type="text"></div>
</td>
<td>
<div class="view">three</div>
<div class="edit"><input type="text"></div>
</td>
<td>
<input type="button" class="edit" value="Edit">
<input type="button" class="send" value="Send" disabled>
<input type="button" class="cancel" value="Cancel" disabled>
</td>
</tr>
</tbody>
</table>
with:
table.editable div.edit { display: none; }
and
$(function() {
$(":button.edit").click(function() {
var row = $(this).closest("tr");
row.find("input.view").attr("disabled", true");
row.find("div.view").each(function() {
// seed input's value
$(this).next("div.edit").children("input").val($(this).text());
}).fadeOut(function() { // fade out view
row.find("div.edit").fadeIn(function() { // fade in edit
row.find("input.edit").removeAttr("disabled"); // enable edit controls
});
});
});
$(":button.cancel").click(function() {
var row = $(this).closest("tr");
row.find("input.edit").attr("disabled", true");
row.find("div.edit").fadeOut(function() {
row.find("div.view").fadeIn(function() {
row.find("input.view").removeAttr("disabled");
});
});
});
$(":button.save").click(function() {
// ...
});
});
