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!
I have a text box im dynamically adding to the dom created with this line of code
When I try to get the value of the text box by referring to its id. I get an "undefined". I can get the value if I use plain javascript.
After loading a HTML fragment using AJAX, I can not select the newly embedded elements using the $("#id") notation. document.getElementById works fine though.

Code:
<table class=newsfeed_table>
<tr>
<td class="newsfeed_table_icon"><img src="/CodeIgniter/verkstad/icons/nf-msg-cr.png" alt=""/></td>[code]....
It's basically just a table containing a message, who wrote it and when.I'm trying to build a function that filters what types of posts are visible in the newsfeed. So by clicking a button I want to be able to filter out the "message"-post or the "sale-alert"-post.Only way I can see which type of post it is, is by looking at the image source in the table. So depending on what that is, I want to set the table to display:none.
But I've been looking into the jquery selector a bit but I can't make it work. I've tried with .each(function and child selector...
Previously when developing my own modal windows I have been creating a "mask" div directly in my markup, in the CSS setting it to be display:none and then setting it to show() by jQuery when a button is clicked.
I'm sure there is a better way to do this but i'm getting a little stuck.
I tried adding the "mask" div and its content to the body using prepend() when my button is clicked but i found i then can't select any of the added elements in jQuery.
How can you select elements you have added to a page by jQuery?? Also if this is the right approach whats the best way to insert a block of html to a page??
I'd like to do something like this: After the page is loaded I have some forms with submit buttons. The buttons have a class called "open". By clicking any of these buttons the script is using AJAX to take some data from database and add some HTML to the document. This part of generated HTML has also buttons with a class "open". By clicking any of the new buttons script should do what it does with the old ones. The problem is I have no idea how to "refresh" a click function. After generating HTML it "sees" only the old buttons.
Here's some code:
$(document).ready(function(){
$(".open").click(function(){
var idVal = $(this).parent().parent().find("#PlaceId").val();
if($("#admin_places_"+idVal).html()=='')
[Code].....
I have two text fields one is TECH field and another is JOB NUMBER... If I type a number in the tech field and If I select a number from the autopopulated/autosuggested list of tech number(which is queried from the database) it should display a dropdown list of JOBNUMBERS associated to that particular TECH number. The TECH is not a Primary key in database)
This is the code that I have to fetch the and the tech number will be the autosuggest field for which I have used JQUERY..

Can this jQuery function be created so I can add the function to "#<%= chbNuevoJugXX.ClientID %>" instead of "#<%= chbNuevoJug01.ClientID %>" and then use the XX to how hide the corresponding row?
This seems to be a peculiarone. Let me set the stage.I am selecting the href inside of ananchortag.I MUST disable all anchor tags inside my div.Here is the problem, I am redirecting old content to new content.I have over 1200 pages all with 1-20 anchor tagsAll of the anchor tags have a regular href url OR a javascript function.It looks like this:"javascript:open_window('detail1.html')"All I want is a way to extract the:detail1.html which can bedetail21.html ordetail.html also (thought about using slice to cut out what I need)

Here's the basic HTML

I want to show and hide the <li> Element. thought i'd do this by applying a css-class to the element

$(".download_liste li a").click(function() {
var showPic = $(this).attr("href");
$("[name*="showPic"]").next.toggleClass("hiddenpic");});

Well, it doesn't work, anybody care to tell me why? Or am i way off?
I would like to grab the onChange value of a select box which is inside a <td> and pass it to the next <td> and place it in a <span>
My php iterates multiple table rows with select boxes and a line total span.
I want it to work similar too..
But of course that wont work because the span is not inside the select.

I have an autocompleter in which i am trying to grab the text in the first element in a list of returned results from the db. I have been able to grab the first element in the list with the below code however, it brings up an alert for every realtime list that comes back so multiple times. Is there a clever way to make an if/else statement that forces it to alert only once?
var item = $('.title_div:first').text();
alert('this item ' + item + ' is the first to be showed');

I'm trying to add a class to a <li> where the href within it contains a string. I can apply the class to the anchor without a problem, but I can't seem to select the parent. Is an anchor a child? <li><a href="random.xls">Random Stuff</a></li>
In this case, since the href contains .xls, I'd like to be able to add a class to it. I've tried a variety of things, most recently this, but no luck: $('li has(a[href$=".xls"])').addClass('excel');
I'm using a form in several places for this project. I don't want to duplicates of this form so I have it as an include file. Each page requires all the same fields, however, there is one page where I'd like to remove two fields.
<fieldset>
<label for="FirstName">First Name</label>
<input id="FirstName" />
</fieldset>
Is there a way to remove an input field and it's label by selecting the ID of the input field? I looked at the JQuery doc, and there's a prev + next selector which shows $('label + input').css ... this will set css properties for an input element that follows a label element. something like $('#FirstName > label + input').remove...
I need to select the lowest element containing a given string.The :contains(text) selector returns the element I want but also allits ancestors (since they too contain the text). I haven't been ableto figure out a selector expression that returns only the lowestelement.
View 1 Replies View RelatedYou can't select the 'text' part of an 'a' element with css, e.g. in the statement <a>some text </a> you can't use a css attribute selector a[text = "some text"]{} to style the 'a' element. You can select all named attributes such as HREF, TITLE, etc. Does jquery's .attrib map strictly to the css usage or is there some way I can match on that part of an 'a' element?
I need this because a menu list I'm working with doesn't by default require a TITLE element so I can't assume I can match on this attribute.

i've been breaking my brain about this issue for a bit now, so here is my question.
I have a SELECT with various OPTIONS

I'm trying to find the currently clicked index of .accordion_trigger from within another element.
When inside the .accordion_trigger click event I can simply do the below to get the current clicked index:
Code:
$('.accordion_trigger').click(function(){
var index = $('.accordion_trigger').index(this);
}
return false;
});
Obviously this doesn't work when called from within another element. I understand that 'this' is part of the problem but can't seem to find a way to form the code in such a way for it to produce a valid result. Thus far I only get -1 or 0.
When .accordion_trigger is clicked it has an "$(this).toggleClass('active').next().slideDown();" applied so in theory I shold be able to search for which of the .accordion_trigger's are "active".
I've also tried doing this via the below method but to no avail:
Code:
var current = $('.accordion_trigger');
current.each(function() {
if ($(this).hasClass('active')) {
