I was wondering if there is a "selector construct" that matches an element having more than one child. So I'm looking for a solution that doesn't need
an if statement such as;
if($('ul').children().size()>1)
{
//do this
}
[Code]....
But I'm looking for a selector that already looks for these conditions. Kind of like how :has() works but then a check for more than one child.
is there any way one can test if an element matches a jQuery selector? I'm not trying to locate elements, just test for match.
More specifically, when using event delegation and a common callback function for multiple events, is there a way to check the event's currentTarget against a selector?
In the following example, how can I check if the currentTarget is the LI node with class "item2"?
<!DOCTYPE html>

<script src="http://code.jquery.com/jquery-latest.min.js"></script>

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 2 Replies View Relatedaccording to the docs this 'should' work in all IE versions except 6.Examples :
$("#gallery > img").css();
$("#gallery").children("img").css()
Even tried $("#gallery").find("img").css() None of those methods will work in all versions of IE(even 8). Works just fine in FF, Safari, etc...Is there a work around or another method of selecting the children of a selector in IE? I would really like to not have to add extra classes to those images just to select them.
What is the syntax for accessing the children of a class, where the class is a variable?The html structure is multiple divs like this:
<div class="class1 class2 class3">
<p class="x"> lorem</p>
<p class="y"> ipsum</p>
<p class="z"> yadda</p>
</div>
(There's a structural reason for accessing the child <p> tags, rather than just the parent <div>s. Some <p> tags in some<div>swill have previously had a style change applied: if the changes are now applied only to the parents, some children won't change… at least not till they're hidden).Anyway: this code doesn't work, doesn't generate a FF error message, and doesn't stop subsequent chained functions from operating. So it can't be far off; and the syntax$(cl + ' > p') works ok in another function.
I'm trying to determine if the id of an element matches a String that has multiple parts.
Code:

The value of this.id is "platform_SWFUpload_0_0" but the result of thisID.match (pattern) is null.

I am using the contains selector for one element because I do not know the full ID. Since I only need the first element it finds should I be adding something to improve performance?

I need to get the attribute id of the current element which comes from a selector. As I found out with the help of this forum I need to use $(this).attr("id"). Unfortunately this just returns "undefinied" for me. Does anybody have an idea why this doesn't work?

I've got a reference to a TableCell and I'd like to use jQuery to get the first instance of an <IMG> tag within that TableCell, but can't get the syntax right, I understand how it would work if I were to reference the TableCell by and ID or class, but not when I have a direct reference to the cell, I've got:
What the jQuery syntax should be to get the first img tag within "tdRef"?

I'm using jQuery with Google jsapi and some strange problem occurs:
google.load("jquery", "1.4.2");
google.setOnLoadCallback(function() {
test();
});

When I run this code, alert returns null, not array. The same with any element, f.e. "#element". Why it doesn't work?
I'm working with jQuery on a form where each input element is contained in an <li> element.
Some fields are read-only, identified by a class ".readonly", and I'd like to bind a jQuery function to these fields' "focus" event, to send the focus to the next input whose class is not read-only.
But, because of the containing <li> elements, I don't think .next('input') will work, since the <input> tags aren't siblings.
Is there a simple selector that will do the job without having to climb up and down the DOM via parents and children? To me that feels unsatisfactory and brittle, because should the designer decide to change the layout (lists within lists, <div>'s within <li>'s), my DOM-climbing code might break.
I'm using the following code that adds to <a> tags to each <td> inside a table.
$(document).ready(function() {
$('.calendar td:not(.notinmonth.)').each(function() {
$(this).append('<a href="#" class="available am">AM: Available</a>').append('<a href="#" class="available pm">PM: Available</a>');
});
$('.calendar td:not(.notinmonth.)').each(function() {
$(this).has('.event').remove('.am');
});
});
The second half of the code looks to see if any of the cells contain an element with class 'event'. If one exists, then the '.am' anchor should be removed. However this does not appear to be happening. After carrying out a few tests with the 'alert' function, it looks as though the script thinks that every cell contains a '.event' element, but I have no idea why! Not only that, it doesn't remove the '.am' link from any of them.
Here is the markup for the table (the cell with 'Day 9' in it is the only one that should match having an '.event' element:
<table class="calendar"><thead>
<tr><th>Mon</th><th>Tue</th><th>Wed</th><th>Thu</th><th>Fri</th>
<th class="weekend">Sat</th><th class="weekend">Sun</th></tr>
</thead><tbody>
<tr><td class="notinmonth"></td><td class="notinmonth"> .....

My HTML is like this:
<div class="feature">
<h2>Heading Goes Here</h2>
<img src="photo.jpg" />
[Code]....
What I want to happen is for the element inside the .feature class to appear when the <h2> of that <div> is clicked I tried using next() and a few other methods but it doesn't work as neatly as I want it to - how can I tell jQuery to just return the element within that div (and not all elements which are inside a .feature class)?
I've 2 field sets and a div inside each fieldset with some contents. When the legend of the current fieldset is clicked, I will toggle the div contents. I'm trying to write a generic function which can be used by everyone. Here is my design:
<fieldset id="fs1">
<legend id="leg1">First Legend</legend>
<div id="div1">
