I would like to be able to test if an element already has a style applied to it. This style might either be an inline style, or come from a stylesheet. I'm writing a plugin which needs to apply a CSS style to an element if it's not already there.
View 1 Repliesi have got about 50 definition lists on one html-page witch all look linke this:
<dl>
<dt class="title">aaa</dt>
<dd class="subtitle">bbb</dd>
<dd class="city">ccc</dd>
<dd class="email">ddd</dd>
<dd class="website">eee</dd>
<dd class="description">fff</dd>
</dl>
if the dt-element in one of the definition lists has a specific css-property (e.g. length > 100px) then the dd-element with the css-class "subtitle" in the same definition list should be removed.
I'm doing a very simple expand/collapse function using 'slideToggle'. The button that triggers this event simply says 'Expand/collapse'. I want this text to change depending on whether an element is visible or hidden.

I'm trying to run a function that reads the css property of an element and copies it over to another element on click.
I'm sure a huge part of my problem is that I'm stillstrugglingto learn the correct syntax for things, but I'm sure it's framed like this:
I didn't want to post my ACTUAL attempt to code this, mostly out of shame. But I'm pretty certain that it's ridiculously incorrect.
Has anybody seen a function which checked if one of passed elements is
nested in the node of another element passed to function, no matter how deep
it is nested ?

I'm trying to run some code when a H2 element is clicked on an unordered list below it. The problem is, the code runs whether the h2 has a ul below it or not.
h[x].onclick = function(){
var ul = this.nextSibling;
while (ul.nodeType != 1){
ul = ul.nextSibling;
}
So, if I have something like this:
<h2>Subtitle</h2>
<h2>Subtitle 2</h2>
<ul><li>List</li></ul>
Clicking "Subtitle" runs the function on "Subtitle 2". I don't want the function to run unless the next element is an ul. How can I verify that the next element is an unordered list and if not, don't run anything?

View 1 Replies View RelatedIs it possible to check for the existence of an element? I have a dynamic
page which may or may not have a <div> holding a bunch of thumbnails, and I

Generates an error.... I was hoping it would just return false or

I've been having this issue with Javascript that is just not getting resolved for a while. What I am basically doing is building a simple web browser extension that injects javascript on certain pages. I am using Firefox, Chrome and Safari. The issue I am having is accessing these so called "special properties" on a particular page. They look like the regular classNames, id, textContent and such but don't appear to be standard. It would be very helpful if I can access them.
A particular example would be in Yahoo Mail. When you are in your inbox you have list of messages. With each message row there are associated attributes. You can get to them with your web inspector or if you search for the div element with id "PagedTableView_wrapper", then follow the first child and then second child and you get a list of these messages being rendered. Each one of those rows has the regular className properties and such but also has "_checked", "_focused", "_selected" that look like custom Yahoo ones. I basically want to read those.
The issue is I can't. I always end up getting a null exception, as if it doesn't exist. I can read the className and the other standard ones fine, but not the special ones. (I've verified its the same element as well). I have tried the DOM navigation route with indexing, jQuery and XPATH, all with the same result. The weird part is that I can see them with the webInspector! Whats even more strange is that if I run firebug or commands in the Console, it actually works! But it doesn't work for my injected code/extension! Baffled.
how to change the css display property of a table, from hidden, to block outside of an iframe.
//This data is outside of the iframe
<style>
#table {display: hidden; z-index: 100;}
</style>

I ended up having to preset style with JavaScript.
Here is what I did.
CSS Code:
JavaScript Code:
HTML4Strict Code:
The first time I hit toggle, nothing happens. The second time I hit toggle, the hidden list appears, but only because I used JavaScript to set the display property.
My workaround is to do this in the HTML after the element to be toggled.
JavaScript Code:
Putting this code in the elements onload event property didn't work either, which I found odd, but I read that it was not the recommended way of doing this.
I can't figure out why the CSS declaration didn't load into the JavaScript HTML DOM. I suspect it's some sort of order of execution thing, like the difference between the two following function declarations.
JavaScript Code:
I'm writing a script that dynamically generates a menu table. Each TD has an onclick property which serves as a link. Everything works properly in other browsers since setAttribute onclick works. However, this function does not work in IE, and you're supposed to do this instead:
elementName.onClick = "blah";
Here's my code that works in all browsers but IE:
Code:
var truePath = "document.location.href=" + "'" + "/" + urls[i] + "'";
cell.setAttribute("onclick",truePath);
cell.onclick = truePath;
For IE, if I set the cell.onclick value to truePath, nothing happens when I click on the menu. However, it works fine in Firefox and Opera because of the setAttribute function. How I could get this to work in IE? My script is complete besides this part... I hate IE. Why can't they follow the rules?

i have a menu generated by a list with nested lists. i want the parent link to stay highlighted when the mouse hovers over the sub menus. because those sub menus are also generated by jquery (qtip), CSS alone won't do it (triedul.topnav li:hover a {background-color: #F00;}).is there a way to do this using jquery?
View 15 Replies View RelatedThe page I am working on will have a series of checkboxes. The boxes will be in the format of "parent" with one checkbox and then a "child" div with multiple checkboxes. The idea is being able to check a parent checkbox and have all the checkboxes in the preceding child div get checked as well.
Here is the layout:
<div class= "parent_div">
<label>
parent
</label><input type='checkbox'/>
</div>
<div class = "child_div" >
<label> child </label>
<input type = 'checkbox'/> .....
This does not work. The checkboxes do not get checked.
I know that the selector is working because if I assign a function to them like this:
$(".parent_div INPUT[type='checkbox']").
change(
function(){
var child = $ ( this ).
parent().
next( ".child_div" ); $ ( child ).
children ().
change (
function (){
alert (
"changed"
); }); });
It will work, the function get"s assigned to each checkbox in the div. Why my boxes are not getting checked? On a side note I found this curious, if I try to access the checkboxes by specifying a selector type in the children method like this :
$( child ).
children ( "INPUT[type='checkbox']" )
or
$( child ).
children ( "input" )
It doesn't select the boxes. In case anyone mentions it I know that the child divs are not actually children of the parent divs, all these values are coming from a database and the names were chosen based on the database relationships.
I am trying to target all PDF document links on a website and add to the href URL. The problem is, some of the links are relative and some are absolute... Because all PDF's don't exist in the same DIR (or even in the root), how can I check for the "/" and then append? [code]which works fine if the existing URL is an absolute path (i.e. "/document.pdf") but how do I also account for those URL's that have a relative path (i.e. "document.pdf") ?? URL...

View 1 Replies View RelatedI'm creating a script to get the next photo without reloading a webpage. To make it more smoothly, I fadeOut() the old image, and fadeIn() the new image.
However, when the new image is not yet fully loaded, the fadeIn() method doesn't really make sence. So I wonder if there is a way to first show an ajax loader, and after the new image is fully loaded, fadeIn the new image.
This is how far I got so far :-)
I first have to remove the first img tag, and inject a new one in the DOM, otherwise the old image flashes for a second, before the new one appears ;-)

$.ajax({

My question is why isn't this working? that it's probablybecauseit's been loaded dynamically andif ($('#load').length) is not checking dynamic content - but how would Iamendthe if statement to also check dynamic content?

View 2 Replies View RelatedIs there some way to determine if the XML returned via a $.ajax() call is well formed? My experience is that if badly formed XML is returned (eg: a missing ">") then the return value is "success". However I notice that data.childNodes[1].textContent contains a very specific error message that points to the line which has the syntax problem. Is there any (documented) way to know if the "success"-ful call to $.ajax() actually returned a poorly formed XML file?
