I have a function where you click on something and then a resizable div toggles with content loaded (.load function).
$("#menucontent").load("loader.php?c=menup");
$("#menucontent").draggable();
$("#menuc").click(function(){
$("#menucontent").toggle(); //
$("#menucontent").resizable();
});
Basically this loads the data from loader.php to the div with id menuc.
So far so good.. Data retrieved from loader.php :
echo '<a class="offertezoek" href="#">ZOEK OFFERTE<div style="display:none;" id="offertezoek"><input type="text" id="offertezoek" name="offertezoek">TEST</div></a><br /><br />';
Now the problem comes, I want to create a function for the data loaded.
The data gets loaded but the function does not work.
Is this because the page is already ready and Jquery executed all the javascript before the data was in the div offertezoek (got added afterwards with .load("loader.php") ??
NEW FUNCTION :
$(".offertezoek").click(function(){
$("#offertezoek").toggle(); //
});
Try this
$(document).on('click', '.offertezoek', function(){
$("#offertezoek").toggle(); //
});

I am working on the Jquery A href (used as Button) with button name Install. I've wrote the code for the calling Jquery AJAX file , Ajax file name is update.php.
Once ajax successfully executed , I'm changing a href label using.
$(.install-blue).text('Stop Installing');
Now , I am trying to call updateStop.php. When i click on the Stop Installing (a href).
Issue is both are sharing same class name, so that it calling update.php
Is there any unique way to execute this operation ?
You could use HTML 5 data attribute to save the state like for example : jsfiddle
Html
<a class="install-blue" data-state="stopped">Start Installing</a>
<div id="msg">
</div>
Jquery
$(document).ready(function(){
$(".install-blue").click(function(){
if($(".install-blue").data("state") == "stopped"){
$(".install-blue").text("Stop Installing");
$(".install-blue").data("state", "started");
}
else{
$(".install-blue").text("Start Installing");
$(".install-blue").data("state", "stopped");
}
});
});
Use:
$('.install-blue').addClass('fistClass');
When the user clicks on install.
Then use:
$('.firstClass').text('Stop Installing');
When the user click on stop installing.
Fiddle
HTML
<input type="button" href="update.php" value="Install" class="install-blue" />
jQuery
$('.install-blue').click(function(){
var url=$(this).attr('href');
alert(url); ///call this ajax url
$(this).val('Stop Installing'); // add this on ajax success
$(this).attr('href','updateStop.php'); // add this on ajax success
});
I am not sure if this example is what you want to do.
$(document).ready(function(){
$('.selector').click(function(e){
e.preventDefault();
if($(this).text() == 'Stop Installing'){
//DO STOP ISTALLING STUFF
}else{
//DO INSTALL STUFF
$(this).text('Stop Installing');
}
});
});
im having small image gallery that uses fancybox. So on each image there is a hover and popup effect. Below is my code
<div class="one-third column hover">
<a href="large/28crowview_ld.jpg" class="image-box">
<div class="photo">
<span class="text"><span class="anchor"></span></span>
</div>
<img src="large/28crowview_ld.jpg" height="170px" width="260px"/>
</a>
</div>
the above code works perfectly.
but im using a ajax controller that returns the above code using an echo
echo '<div class="one-third column hover">
<a href="large/28crowview_ld.jpg" class="image-box">
<div class="photo">
<span class="text"><span class="anchor"></span></span>
</div>
<img src="large/28crowview_ld.jpg" height="170px" width="260px"/>
</a>
</div>';
but when i use the echo tag the images are displayed but non of the hover effects are visible. it was very odd. and i also noticed the same issue on my social bar.
It works perfectly when i use it in a html view. But when i echo, i see the code in the source but the icons are not visible
echo '<div class="supersocialshare" data-networks="facebook,google,twitter,linkedin,pinterest" data-url="'.$share.'" data-orientation="line"></div>';
all the images are placed correctly, no js conflicts.
Below is the java script im using
<script type="text/javascript">
$(document).ready(function() {
var track_click = 0; //track user click on "load more" button, righ now it is 0 click
var total_pages = <?php echo $total_pages; ?>;
$('#results').load("<?php echo base_url() ?>fetch_pages", {'page':track_click}, function() {track_click++;}); //initial data to load
$(".load_more").click(function (e) { //user clicks on button
$(this).hide(); //hide load more button on click
$('.animation_image').show(); //show loading image
if(track_click <= total_pages) //make sure user clicks are still less than total pages
{
//post page number and load returned data into result element
$.post('<?php echo base_url() ?>fetch_pages',{'page': track_click}, function(data) {
$(".load_more").show(); //bring back load more button
$("#results").append(data); //append data received from server
//scroll page to button element
$("html, body").animate({scrollTop: $("#load_more_button").offset().top}, 500);
//hide loading image
$('.animation_image').hide(); //hide loading image once data is received
track_click++; //user click increment on load button
}).fail(function(xhr, ajaxOptions, thrownError) {
alert(thrownError); //alert any HTTP error
$(".load_more").show(); //bring back load more button
$('.animation_image').hide(); //hide loading image once data is received
});
if(track_click >= total_pages-1)
{
//reached end of the page yet? disable load button
$(".load_more").attr("disabled", "disabled");
}
}
});
});
</script>
inside fetch_pages
$page_number = filter_var($this->input->post('page'), FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH);
//throw HTTP error if page number is not valid
if(!is_numeric($page_number)){
header('HTTP/1.1 500 Invalid page number!');
exit();
}
$item_per_page = 5;
//get current starting point of records
$position = ($page_number * $item_per_page);
$cottages = $this->properties->getstuff($sub_location,$position, $item_per_page);
foreach ($props as $cots):
echo'<div class="container section" id="'.$cots["id"].'">
<div class="one-third column hover">
<a href="'.$cots["image_url"].'" class="image-box">
<div class="photo">
<span class="text"><span class="anchor"></span></span>
</div>
<img src="'.$cots["image_url"].'" height="170px" width="260px"/>
</a>
</div>';

Im building this project using codeigniter, php and jquery. Any help will be appreciated.
You seem to have some serious problems understanding the overall architecture of a web application, what is happening on the browser of your client and what is happening on the server, what php does, and so on. You should read up on that.
However, your problem is most likely related to the fact that your hover and popup effects are being accomplished by something equivalent to this:
$(".hover").on("hover",function () {
// BLAH
});
If this is the case, then any elements with class hover loaded after the event handler has been attached (that is, through ajax) will not have that event handler attached to them, a simple fix would be to attach the event handler to the container and use a delegated event handler, something like this:
$(document).on("hover",".hover",function () {
// This handler is attached to the document but applies to any .hover elements inside it
});
Another fix would be to run whatever function attaches your "fancybox" functionality to an element after the element has been loaded through ajax. Hard to get it right without some reference code but i assume it would be something like:
$.get(url, function (data) {
var elem = $(data);
$("#container").append(elem);
elem.fancybox();
});
please provide you JavaScript code, I would like to throw my cent. I bet you are using hover method instead of live hover or on hover functions
just like the following :
jQuery('#div').click(...); // this will work fine if you place your code in page not posted back from ajax request or dynamically created
jQuery('#div').live('click',...); // this will work even if the element was created dynamically or from ajax request.
jQuery "live" link
jQuery "On" link
one more thing, be careful the live function is deprecated and removed from jQuery 1.9
According to anpsmn comment i had to re initialize the complete fancybox plugin within
$(window).load(function() {
it worked perfectly..
I have very limited knowledge with scripts so I hope you guys can help me with a simple solution to a small problem that I have...
I'm using the following jquery function to refresh a div with new content when a link is clicked
<script>
$(function() {
$("#myButton").click(function() {
$("#loaddiv").fadeOut('slow').load("reload.php").fadeIn("slow");
});
});
</script>
My problem is, I need to send 2 variables to the reload.php page to use in a mysql query (I have no idea how to accomplish that), also I need to make multiple links work with this function, at the moment I have multiples links with the same id and only the first link works so I guess I must associate different ids to the function in order for this to work, how can I do that?
here's the page where i'm using this: http://www.emulegion.info/teste/games/game.php
You may want to use document ready instead of function on your first line as this will make sure the code is not executed until the full page (and all elements) have loaded.
You can then use the callback functions of the fade and load to perform actions in a timely manner.
additional variables you can add after the .php, these can then be read in your reload.php file as $var1 = $_GET['var1'];
Do make sure to sanitize these though for security.
<script type="text/javascript">
// execute when document is ready
$(document).ready(function() {
// add click handler to your button
$("#myButton").click(function() {
// fade div out
$("#loaddiv").fadeOut('slow',function(){
// load new content
$("#loaddiv").load("reload.php?var1=foo&var2=bar",function(){
// content has finished loading, fade div in.
$("#loaddiv").fadeIn('slow');
}); // end load content
}); // end fade div out
}); // end add click to button
}); // end document ready
</script>
For different variables you could add a HTML5 style variable to your button.
<input type="button" id="myButton" data-var1="foo" data-var2="bar" />
You can retrieve this when the button is clicked:
// add click handler to your button
$("#myButton").click(function() {
// get vars to use
var var1 = $(this).data('var1');
var var2 = $(this).data('var2');
...
load("reload.php?var1="+var1+"&var2="+var2
if you have multiple buttons/links I would use class instead of id "myButton". that way you can apply the function to all buttons with the above script. Just replace "#myButton" for ".myButton"
First, you should use .on('click', function() or .live('click', function() to resolve your one click issue.
You'll want to do something like:
<script>
$(function() {
$("#myButton").on('click', function() {
var a = 'somthing';
var b = 'something_else';
$.post('url.php', {param1: a, param2: b}, function(data) {
//data = url.php response
if(data != '') {
$("#loaddiv").fadeOut('slow').html(data).fadeIn("slow");
}
});
});
});
</script>
Then you can just put var_dump($_POST); in url.php to find out what data is being sent.
Try creating a function that would accept parameters that you want.
Like:
$(document).ready(function(){
$('.link').click(function(){
reload(p1,p2);
});
});
function reload(param1, param2){
$("#loaddiv").fadeOut('slow').load("reload.php?param1="+param1+"¶m2="+param2).fadeIn("slow");
}
But by doing the above code your reload.php should be using $GET. Also you need to use class names for your links instead of id.
<script type="text/javascript">
// execute when document is ready
**$(document).ready(function() {**
**$("#myButton").click(function() {**
**$("#loaddiv").fadeOut('slow',function(){**
**$("#loaddiv").load("reload.php?var1=foo&var2=bar",function(){**
// content has finished loading, fade div in.
$("#loaddiv").fadeIn('slow');
});
});
});
});
</script>
$("#myButton").click(function() {
// get vars to use
var var1 = $(this).data('var1');
var var2 = $(this).data('var2');
so i have a php loop, i am using jquery slide toggle to hide/show a table with sql results. currently the table is loaded using php only, but as there is a lot going on its causing some loading problems i need to fire the ajax with the slide toggle btn, so it only requests the current items details when the button is pressed. i can get it to call the php file from the jquery but im having difficulty passing the value for each item across, so it can perform the request on the database. here is what the php foreach loop content looks like;
<span class="searchitem">
// some visible content here
<span value="item name" class="btn">button</span>
<span class="slide_area">
// hidden slide content ajax needs to populate with php result
</span>
</span>
this html is repeated i use jquery slidetoggle to hide the slide_area, what i need to do is populate the slide_area with results from php, the php file needs the name to return the results the name is passed via get with the url, so i only need append the url with the actual name from btn's value, im sure this cant be that difficult but here i am.
here's the jquery:
<script type="text/javascript">
//<![CDATA[
$(document).ready(function ()
{
$('.searchitem').each(function () {
$(this).find('.slide_area').hide();
$(this).find('.btn').click(function ()
{
var ajax_load = "<img src='images/spinner.gif' style='width:50px;' alt='loading...' />";
var loadUrl = "ajax/item.php?name=";
var loadName = $(".btn");
var Name = URLEncode(loadName);
var loadString = loadUrl + Name;
$(this).parent().find('.slide_area').slideToggle(1500).html(ajax_load).load(loadString);
});
});
});
//]]>
</script>
i need to get the value from btn and append the loadURL, im open to sending the data a different way like through post if needed, updated the jquery still not working what am i doing wrong here?
Thanks.
The easiest way would to use the Phery library http://phery-php-ajax.net/
the key here is the data-phery-remote="toggle" that will call the PHP function automatically on click, and can be reused everywhere
<span class="searchitem">
// some visible content here
<span value="item name" data-phery-remote="toggle" class="btn">button</span>
<span class="slide_area">
// hidden slide content ajax needs to populate with php result
</span>
</span>
The logic is reversed, the load will happen with only one AJAX call, instead of two.
Phery::instance()->set(array(
'toggle' => function($data){
$r = new PheryResponse;
/* do your code, fill $html_content */
$r->this()->siblings('.slide_area')->html($html_content)->toggle();
return $r;
}
))->process();
I have a a script that on click do a ajax call connect to the database get imagename and set the image name inside an < -img - > with the right path also it adds a hidden checkbox after it and then echo it.
i then take the ajax message returned and put it as div's HTML. my question is will i be able to preform more action on the inserted content..
The main goal is to be able to click on the image as if it were a checkbox(this part is already sorted for me) however no matter what i try i cant have a .click function works..
Here is the code.
This is the PHP part that echos the images.
if($_POST['updateIgallery'] == 'ajax'){
global $wpdb;
$table_name= $wpdb->prefix . "table_T";
$imagecounter = 1;
$toecho = '';
$currentselected = $wpdb->get_row("query");
preg_match_all('/\/(.+?\..+?)\//',$currentselected ['image_gal'],$preresualts); // images are stored with /image/.
foreach ($preresualts[1] as $imagename){
$toecho .= '
<img rel="no" id="JustantestID" class="JustaTestClass" src="'.site_url().'/wp-content/plugins/wp-ecommerce-extender/images/uploads/'.$imagename.'">
<input name="DoorIMGtoDeleteIDcheck'.$imagecounter.'" style="display:none;" name="DoorIMGtoDelete['.$imagecounter.']" value="/'.$imagename.'/" type="checkbox">
';
$imagecounter++;
}
echo $toecho;
}
This is the ajax part that send and receive and insert the HTML to the div:
$.ajax({
type: "POST",
url: "/wp-content/plugins/wp-ecommerce-extender/DB_Functions.php",
data: { updateIgallery: "ajax", CurrentDoorIDnum: $('#dooridforgallery').val()}
}).success(function(insertID) {
$("#ImgGalleryID").html(insertID);
});
This so far works what i am having trouble with is the following:
$("#JustantestID").click(function() {
//DoorImageGallery($(this).attr('id')); // the function i will use if the alert actually works
alert("kahdaskjdj");
return true;
});
I hope the question and the code is understandable.
Thanks in advanced.
When you replace element's html, all the elements inside it are removed and gone. That means the event handlers attached to them are removed as well.
You could try attaching an event handler to a higher level element that is static and permanent on your page. Without more info I am going to use document:
$(document).on( "click", "#yaniv", function() {
alert("kahdaskjdj");
});
$('img.JustaTestClass').bind('click', function() {
var checkbox = $(this).siblings('input[type=checkbox]');
if (!checkbox.is(':checked')) checkbox.attr('checked', true);
else checkbox.attr('checked', false);
});
Since the elements are dynamically inserted into the DOM with ajax, you have to delegate events to a parent element that actually exists when binding the click handler, which in this case looks to be #ImgGalleryID
$('#ImgGalleryID').on('click', '#yaniv', function() {
DoorImageGallery(this.id);
alert("kahdaskjdj");
});
