This is the code i created i wonder how can i check if the last element has been selected and how to go start at first element.
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.

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?
Is 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
want a function to check for the existence of the <div>. Doing:
blah = getElementById("thumbnails");
Generates an error.... I was hoping it would just return false or
something... Is there a way of doing this?
I'm trying to check to see if a dynamically created element exists BEFORE creating another element of the same exact type...but my if statement at the beginning is not working and another element is just created.
function writeElement(id) {
if(document.getElementsByTagName('transElement')[0]) {
var id = id;
killElement();
writeElement(id);
}
var id = id;
var transElement = document.createElement('transElement');

[code]so now if url is xyz.html, the i'm getting the content of that page through AJAX and loading it to a DIV element(x).....and then accessing the div elements "name","category" etc.,but if urls point to heavy pages, it's slow process to do this work. so I WANT TO CHECK WHETHER THOSE DIV ID's EXIST IN THAT PAGE OR NOT WITHOUT LOADING THEM and then GET THEIR VALUES IF EXISTS.
View 3 Replies View Relatedi 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 ;-)

Okay I have a blank html page with the following in the head:
$(document).ready(function () {
$.ajax({
url: 'include.html',
success: function(data){
[Code]....
My question is why isn't this working? that it's probablybecauseit's been loaded dynamically andif ($('#load').length) is not checking dynamic content - but how would Iamendthe if statement to also check dynamic content?
Here's what I want to happen with the above: "if txComments is there don't append it again"owever when I run this code, it appends a new "txComments" every time the code is triggered.
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?
View 3 Replies View RelatedIs there a way to check the page for invalid usage (e.g. text boxes using .text which doesnt exist)? I originally thought I could use the .data("events") but then realize that .text and .val isn't an event which is pretty obvious but I'm stuck now. I already know my selector is $('input[type="text"]') but is there any way to see if anywhere on the page is improperly calling .text()?

I'm checking for a radio button's value and hiding/showing a node based on that value, but it's not working right. Two radio buttons: one's value is yes, the other no. If you click on yes, the div shows up. When you click no, it hides, so that works.
But I have a list of checkboxes that also may or may not show that element based on the radio button selection, and it's this part that isn't working.
$('[name="'+obj.name+'"]:checkbox').click(function () {
aThroughS = ($('[name="'+obj.name+'"]:checkbox:lt(19):checked').length > 0),
tSelected = ($('[name="'+obj.name+'"]:checkbox:eq(19):checked').length > 0),
