[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.

I was wondering if there was any method for determining the existance (or no existance) of a given DOM element using its Id.
My problem is the following :
I have some ajax stuff that does some crazy things to my original document well... errr... such as simply adding some new layers with a unique Id.
What I wanted to do, from another JS function that is triggered later on, was to check if theses layers were existing or not before populating them.
For example something like :
if (document.getElementById("blah").exists){
//populate the thingie !
}
[url]
This is all triggered from a, input :select. If a specific option is selected, generate a text field to enter a reason. the generated input carries an id: txComments_01/01 (this being the value pulled from the attribute "data-date".
The client only wants one per week, so if it exists already don't re-create it
When I create an array I use commas as the separator between elements of
the array e.g [1.1, 2.2, 3.3] but what happens with languages that use
commas as a number's "decimal point"? e.g. [1,1, 2,2 , 3,3] is now a 6
element array.
i need to do a click on a picture in an iframe without using a mouse
click because this iframe is not visible.
Thus i wrote this :
function updtframe() {
strButton = document.getElementByName("submit").value;
document.getElementById("htmle").contentWindow.document.body.innerHTML
= strButton...;
}
And there I'm stopped idon't know how to make a click.
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?
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?
$(document).ready(function(){
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.

Is there any way to check if exists a cookie from a domain2 in domain1?
The purpose here is if the cookie from domain 2 exists then do an action in domain 1.
For example:
Erase cookie or do an action.

I have inherited a project with some code that runs fine for some
frames but not for others. This is a frames based project, and
(apparently) sometimes there is a parent frame, and sometimes not. When
there is no parent frame, you see this error message:
'parent.frmUpper.document' is null or is not an object
I would like to know if there is a way to check for the existence of an
object by name so I can determine what to do next.
Initially the form is loaded using ASP and HTML and the ü codes
display the characters correctly. I have the values stored in a
javascript array so that I can more easily and dynamically change the
state/region dropdown when the country changes. However, when my
javascript code tries to add the new option and print out new region
the literal value such as "Würrtemberg" is displayed instead of
the special character.
Can this be done in javascript?
My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer here:
The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script>
About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to.
When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00.
I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top.
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:

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?

I am new to query. So far I have found this a huge improvement on coding all this stuff myself. I want to create a button which will add a new div element to the html page. I can do this in php however I want to know if there is a simple way of doing it in query and where I would look to find the documentation and examples of this function.
