JQuery :: Selecting Element Dynamically Inserted Into DOM

Sep 28, 2010

I can't figure out how to coax JQuery in to selecting an element that is manually (dynamically) inserted in to the DOM after the page loads. For example:
If I have HTML:
<div id="bar">
World!
</div>

Then I create a new element and insert it in to DOM:
var foo = '<div id="foo">Hello</div>';
$("#bar").before($(foo));

I end up with this, which is great:
<div id="foo">Hello</div>
<div id="bar">
World!
</div>

Now that's very nice, but later on I might want to do something different with the element I inserted, using JQuery to manipulate that new element. But if I try to do:
myHappyEl = $("#foo");
Then myHappyEl will be undefined. JQuery doesn't see it, presumably because it go attached after JQuery was done watching for such things. How I can coax JQuery in to noticing the existence of new elements created not only in exactly the manner shown here, but in general after the DOM has fully loaded.

I've seen lots of suggestions addressing a possibly related but subtly different issue, wherein the solution is to use .live() to attach an event listener when an element comes in to being. That would be brilliant if I wanted to capture a click event or something, but I don't; I want to be able to select the dynamically added element(s). Perhaps there's a simple way to accomplish this using live(), but I haven't seen it yet. If there is a solution using live then I'd like to know what event and what function to trigger!

JQuery :: Function To Have An Element Inserted, Or Removed From The DOM?

Nov 22, 2011

Is there a possible way to mimic the livequery's function to have an element inserted, or removed from the DOM? As I know the fastest and simpliest way was to use the livequery plugin.

So is there any way to mimic that function with the on, and the off functions yet?

JQuery :: Detect Element Class Change?

Jan 31, 2011

I have some legacy code that creates an image carousel and outputs AFTER the document head has been output - the CSS for this was being aded to a style block within the <body> which although worked is not compliant. I am trying to use jquery to set the css, but one part if failing. This is the original css :

#div_tab_one a:hover { .... }
#dic_tab_one .selected a {...}

How can I inject this css ? the selected class is set by some YUI code and rotates through the carousel setting/unsetting the "selected" class.

JQuery :: Detect What Type Of Tag/element Is Variable?

Feb 13, 2011

I have a variable that contains Form Elements. So these elements can be eitther a :text either a :check box See code below:

var currentValue = $(targetedInput).val() ? currentValue = $(targetedInput).val() : currentValue =$(targetedInput).is(':checked')

I was hopping that this line of code would assign a different value to currentValue depending on what kind of object i have. My idea was that If the current Object is a check bot it doesn t have a val attribute..

Detect If Element Inside A Div Been Dragged Out Of The Div?

Aug 23, 2011

I have elements inside a div. I want to detect that when some clicks and drags the elements outside the div. I want the code to take that elements html code and take it out of the div but still on the page.that way when the person drags the element out of the div the element no longer belongs to the div.

I have elements for example like text or the <a> tag inside a div. everything is draggable. so you can drag the <a> tags . I want to detect if the user drags the <a> tags out of that div to take the <a> tag html code out of the div. So the element no longer is linked or the child of the div. I want it to become a parent of it's own. like right now when you drag the elements and then drag the div, the div will still move the <a> tag that is now displayed outside of the div. I want to break that link... and the same goes the other way around where if there is an <a> tag outside of the div and the user clicks and drags that <a> tag and puts it into a div it will become the divs child.

JQuery :: .replaceWith Not Seeing Inserted Div?

Jan 1, 2012

I'm trying to shrink some jQuery code by using replaceWith, instead of hiding and showing two different items. Since I'd never used replaceWith before, I created a test page, all it has has a div container, with class "one", and inside it the word One.

The jQuery code I wrote is below, it works to replace One with Two, when one is clicked. But clicking Two does nothing. I put in an alert to test what replacement is, and it is correct, a div with class of two. Yet still the second click doesn't return to One.

$(document).ready(function()
{
var replacement;
$(".one").click(function(event){

JQuery :: Get To Text Inserted Into HTML?

Oct 14, 2009

I need to get text data from a web page which are unfortenately inserted into <span> tag by jQuery so it's not actually involved in HTML source file. That means for me I can't get it by classic HTTPRequest (programmatically).

For example, on this page: [URL]

When you enter some text in the textbox, this text will show up under it. But when you open HTML source or download it using HTTPRequest (I do so in C# language but it shouldn't matter), the source won't contain entered text. And this text is what I'm trying get to.

Let's say I have this code:

But when I click on the new paragraph, the event listener for p isn't running.

JQuery :: Accessing .html() Inserted Images?

Jul 22, 2011

I am building a custom shirt design app which uses an Ajax form to allow a user to upload an image, and once it is uploaded it is automatically placed in the next empty <li> in their little gallery... once it is in the gallery they can click on it and insert it into their shirt design. It's all done with Ajax so they never leave the page.

Here's the code that inserts the image into the page once it is uploaded: (this works perfect)

$('#last').html('<img src="uploads/' + filename + '" />');

Once the image is in their gallery, the user can click on it which inserts it into their t-shirt design:

var selected = $(this).attr('src');
$("#container").html('<img src="' + selected + '" width="40" />');

Okay so say their gallery already has 5 images in it an they upload a 6th, the HTML looks like this on page load:

<li class="graphic"><img src="uploads/monkey.png'"></li>
<li class="graphic"><img src="uploads/ltdtee.png'"></li>
<li class="graphic"><img src="uploads/wordpress.png'"></li>
<li class="graphic"><img src="uploads/kitty.jpg'"></li>
<li class="graphic"><img src="uploads/steve.png'"></li>
<li class="graphic" id="last"></li>

The problem is that if I click on one of the first five, it works, the image gets inserted into the shirt design. But if I click on that last one, which now has the image I uploaded in it, it doesn't get inserted into the shirt design. Is there a reason why?

JQuery :: Click Events From <a>s Inserted In A .html() Call?

Oct 17, 2010

I'm using some click events on normal <a> tags. When I rewrite the links within a html() method call, the click events no longer work. I've set up a very simple example here:When the page is loaded, clicking either of the 'link 2' links displays the correct information.When 'link 1' is then clicked, the main information is redisplayed. However, now, the 'link 2' link in the main paragraph doesn't work, although the 'link 2' link in the menu does.

JQuery :: Access An HTML Fragment That Was Inserted By A Different Function?

Oct 19, 2010

<html>
<head>
<script type='text/javascript' src='jquery-1.4.2.js'></script>
<script type='text/javascript'>
$(document).ready(function(){

[Code]...

The above is a simplified example of the problem I'm facing. I could merge functions into one big self-referencing function (i.e. recursive function), but that's ugly and causes other problems (such as when insert form elements and wanting to harvest the user input afterwards). I considered declaring a variable in the top ".ready" function, and have all child functions stuff their HTML changes in it, but that seems to be a pain to keep track of and removes much of the value of using jQuery in the first place...

Is there a nice solution for this? To, after inserting HTML, somehow update the HTML state referred to by jQuery in the non-local scope(s)?

JQuery :: Firing Existing Events From Inserted Html

Oct 27, 2009

I have a problem with jQuery appending new text to a div - but then not firing events attached to the inserted text.Let me explain. I have a div that contains a number of divs - the div has a link and a hidden form. Clicking on the link fires a slideToggle event which reveals the form.When you submit the form AJAX handles it and jQuery builds another div with the correct link and the correct form which it sticks on the end of the list. That all works fine and dandy.What I want to be able to do is to click on the newly-added link and have it behave in the same way as the other elements that were on the page when it was built. However, nothing happens when you click on it. Zip. Nadda. Rien du tout.Usually I have found a way round the problem - but I am slightly stuck on my current project. Apart from forcing a page reload, is there any way to get the browser to see the newly inserted link and apply the jQuery action to it?

JQuery :: Bind Does Not Take Dynamically Inserted Elements Into Account?

Sep 14, 2010

To make it simpler, i've got a div that I populate with buttons (via AJAX), each button has an ID of some table row. It looks like this:

<div id="mydiv">
</div>
and buttons are defined like this:
<input type="button" id="1" do_something="1" />

Now what happens - when page loads, I'm inserting buttons in that div with "id" attribute changed depending on some row within the database table.

[Code]...

it all works fine. Now, when I add another entry in the database and when I dynamically append yet another button - even tho it has the attribute "do_something" - the click action on it does nothing. I know how to get around this "problem" by adding bind action after I've inserted that button but it's literally duplicating my work. Is there way around this so that every newly inserted element has the action "click" bound to it if it fits the selector?

JQuery :: Events Not Working On HTML Inserted Through AJAX Call?

Oct 20, 2010

I've used to an AJAX call to load a HTML table into div. This is working successfully. I know want to use a click event on buttons located within the inserted table.

The click event is triggering on buttons outside the inserted table but not on the buttons within the table.

Do I need to call some sort of refresh function to so that jQuery is able to pick up these events?

JQuery :: Inserted Ajax Dropdown Not Fade On Form Wizard

Aug 31, 2010

I'm using formwizard, and I tried to insert a dropdown into the form by putting this jquery code
$('#aog').change(function() {
if ($('#aog').val()==='yes') {
$.ajax ({
type: "POST",
url: "<?php echo base_url(); ?>index.php/register/mortgator",
data: "aog=" + $('#aog').val(),
success: function(msg) {
$("#bank").html(msg);
$("#signupForm").formwizard("update_steps");
}}); //end of ajax
} else {
$("#bank").html('');
}});
//end of aog event

And this php code
function mortgator(){
$this->load->model('MBank');
$q = $this->MBank->getbanklist();
echo '<label for="mortgator">Mortgator:</label><br/>';
echo '<select name="mortgator" id="mortgator" class="required ui-wizard-content ui-helper-reset ui-state-default error">';
echo '<option value="">Select a Mortgator</option>';
foreach ($q as $key => $list){
echo '<option value="'.$list['bankID'].'">'.$list['bankName'].'</option>';
} echo '</select>';
}
It is working, except that when you click next, other form input boxes would fade, but this input inserted via ajax would not have a fade animation. That's why I added this line of code to the html tag ui-wizard-content ui-helper-reset ui-state-default error but it appears that that does not work.

JQuery :: Removing Dynamically Inserted HTML In Source Code

Jun 3, 2009

Why isn't this code working? I can add items but only remove the ones originally added in the source code, not the ones dynamically added.
<form><div class="list">
<div class="item">
<input type="text" value="" /> <a href=""class="removeitem">Remove this item</a>
</div><div class="item">
<input type="text" value="" /> <a href=""
class="removeitem">Remove this item</a>
</div><a href="" class="additem">Add item to list</a>
</div></form>
<script type="text/javascript">
// Add item to list
$('.additem').click(function(){
var template = $($(this).prev().get(0)).clone();
template.insertBefore($(this));
return false;
});
// Remove item from list
$('.removeitem').click(function(){
$(this).prev().parent().remove();
return false;
});
</script>
