I have a standard menu structured with an unordered list. Some of the items in the menu have sub items, but are not themselves links. Here's an example:
<ul id="mainMenu">
<li><a href="">home</a></li>
<li><a>services</a>
<ul>
[Code].....
How do I select a tag that does (or does not) have a particular attribute? In my case, I want to be able to select all <a> tags in #mainMenu that do not have the href attribute.
I would like to change all img tags with a certain class on the page as follows [code]...
I do not know how to "copy" the value of the img tag src attribute to the background url attribute of the div.
$(document).ready(function() {
The SELECTor shows up in the document but it's not MULTIPLE, no ALT text, no CLICK event handler.
When the page loads there will already be a drop-down on the page, here's an example of the drop down.
<select id="dropdown">
<option value="2121S">Option text</option>
<option value="2122S">Option text</option>
<option value="2123S">Option text</option>
<option value="2121A">Option text</option>
<option value="2122A">Option text</option>
<option value="2121K">Option text</option>
</select>
On page load it will evaluate this drop-down and repopulate it determined on their values. If there is an S in any of the values the drop-down will generate an option for 'S' like so.. <option value="s">S Option Text</option> And for the first code example in this post - the Javascript would be able to repopulate the drop-down with the following:

How can I do a less than in a select e.g. something like $.("span.class [id<"+ a_custom_variable +"]") when I tried that it just selected all span of class with an ID attribute rather than where ID attribute is less than
View 14 Replies View RelatedI am just working on a project where i have to replace the href-attributes of all links by another string. The problem is, that i need the old href-attribute to generate the new one, and i have no idea how to get it

I know there is some way to do it but i forgot it and i looked up the whole internet for it and didnt find it
What I’m trying to accomplish is set an attribute called opacityin any element with a specified value that can be used to toggle whenever the user hovers over the element. The code below works perfectly but one other thing I would like to be able to do is retrieve the attribute opacity after the document loads and fade the element to that value instead of hard coding the ".66". This is probably fairly easy I've just never ran into a situation where I needed to do this.[code]...
View 2 Replies View RelatedI quite like the fact that you may add through JQuery an attribute like alt or title to an element. And I can see that you may also add mouseover using:
$('#aa').mouseover(function(){//does something in here});
However, I want to be able to pass some very specific values too and that's where I'm stuck for an answer. Suppose I want to attach the following:
mouseover="hm(this,'la1',5)"attribute to an <a> tag.
How do I do this by using exactly those values inside the "hm(this,'la1',5)" ?
I am trying to change an attribute of an element but can't figure out what the selector is to select it.
the page code is like this
<div class="slideshow" id="slideshow"><span class="image-wrapper current" style="opacity: 1;"><a title="" href="#2" rel="history" class="advance-link"> <img alt="" src="images/samples/1.jpg"></a></span></div>
I want to add a top css attribute to the img tag.
I tried many things such as
$('.advance-link:first')
$('.advance-link:firstChild')
but none seem to be working. The img gets generated by another script so I can't add an id or class to it. I figured an expert at selectors would be able to explain how to select it.
I have a table with several columns containing input elements populated from a database, e.g.,
On every row, I need to perform a calculation using the value of several input fields. So I tried to access the value of the first input field like so (which had worked in another function):
But for some reason it's returning a 0, and the line below also doesn't work:
But this returns the correct class, so I know it's finding the element:
And if I assign the input element an id, say "count," this works:
Obviously I don't want to fuss with individual id's to get the values. How to understand why the first two examples don't work, and how to fix them?
I have 2 lists on a page and I have a link set up to remove an li item from the one list. I need to check to see if there is a copy of that item in the other list based off an attribute in my li item called qid. How would I look for a child list item based off this custom
attribute? Assuming I have html like the following and I want to get the one where qid=14.
<ul id="ul1">
<li qid="12" id="ul1_1">adfaf</li>
<li qid="13" id="ul1_2">adfaf</li>
<li qid="14" id="ul1_3">adfaf</li>
</ul>
I've got a <select> with the multiple attribute on and then I got some jQuery doing some functions when one of the options is selected. Currently my code looks like this
$("select[name=(thename)] option").click(function() {
// do stuff..
});
and both this and the same with live ("click") works in Chrome and FF, but once again IE drops the ball. I've also tried with .change() but nothing..
I'm having trouble finding the image element by attribute "MyAttr" whose value is supplied: when the "onclick" function is called:
<div class="MyImages">
<div class="imageClass">
<img ... myAttr="abc"/>
</div><div>
<img ... onclick="findTheImageObjectByMyAttr("abc");" />
</div><div class="imageClass">
<img ... myAttr="def" />
</div><div>
<img ... onclick="findTheImageObjectByMyAttr("def");" />
</div></div>
I have a set of elements with the same function attached, how do I get the ID or other attribute value of the element that caused the function to be called?
View 2 Replies View Relatedbut having fun with it. Would like tolearn how to do the following...2) Find the parent <li>.3) Grab the value of the attribute "jcarouselindex" and put it in avariable to be used elsewhere.Sample code below...
<ul id="carousel">
<li class="carousel-item" jcarouselindex="1">
<a href="/someurl"><img src="someimage.jpg" alt="" />

I tried the code bellow, but it didn't work:
<script type="text/javascript">

My html code is this:
<img src="images/1backg.png" />
how can i set the attribute of an item in a select box to selected?
View 5 Replies View RelatedI already know that you can combine multiple attribute selectors, &&-style, by doing:
$("*[name='someName'][value='someValue']");
However, what I was wondering is, is there any way to combine multiple
attribute selectors, ||-style, such that I could select:
$("*[name='someName'][value='someValue']").add("*[name='someName']
[value='someOtherValue']");

$('a[class*=myclass]') selects all a elements whose class attribute contains 'myclass', how do I do the opposite?
View 1 Replies View RelatedI have a page which contains an <ul> list with 5 items. Each of those items has a data-weight attribute which corresponds to its importance in the list. I have to make only one random list item appear and use the weight to make sure that the most important one shows up more often than the least important item.

View 1 Replies View RelatedI'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
If I had a table like this...
<div id="div1" onmouseover="this.href.innerHTML='different click name'">
<a href="somewhere">click</a>
</div>
I know this.href doesnt work - Is there a way to access the <a> element without assigning an id to it ?

View 2 Replies View RelatedThe technique for getting the name of a span element should be just like getting the name of any other element, I would think... but it doesn't work in FF or Chrome. Here's some example code:
