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
want a function to check for the existence of the <div>. Doing:

We have a JSP website intended for viewing with IE 5 (and above)
On a certain jsp page, there are few span objects
(<SPAN ID="name">text</SPAN>), which are created dynamically.
The spans share the same ID, so we are able to reference them as an
array, in the javascript code :
for example:
<SPAN ID="wow">lala</SPAN>
<SPAN ID="wow")kaka</SPAN>
in the JS code:
wow[0].innerHTML = "fafa";
wow[1].innerHTML = "zaza";
It may occur, since these spans are created dynamically by the JSP
page, that on a certain instance of the page, no spans are created.
My question is - how do we know, in the JS code, that no spans of ID
'wow' exist?
We tried several ways:
if (!wow) alert('no wow'); // If there were no spans, this gives a
js error
tried a few other methods which i cant recall of now..
I know of a workaround - to add a 'dummy' span with the 'wow' ID , but
I prefer to know if there is a better way to deal with this.
I am trying to retrieve a clicked objects id I would use the method below:
$(this).attr("id");
However, the id value I am always getting back is lacking the # sign which I need to append like so:var id = "#" + $(this).attr("id"); Then I can utilize the id value. I understand I can just use $(this) to manipulate the object but in certain cases I'd just like the Id value.
So im trying to create a simple file menu, so far I have :
$(function() {
//Rolling over menu items.
$('#FileMenu a').hover(function(e) {

What is the proper way to .append to an element that has been appended? I'm creating a unordered list via jQuery and attempting to append list elements to said list but those elements, loaded from an XML file, duplicate themselves when I do this.
When I append those list elements to an html element that is hard coded into my html file, this does not happen.
I have a textbox with add button, says A. If i click A, a new textbox will be appended.The appended textbox, B will have an ADD button, in order to add new textbox again.The problem I face is I am not sure where or how to include the jquery function of ADD button for Textbox B.My script:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>

I am experimenting the online tutorials.I use .append to add same textblock:
$("input.buttonCAdd").click(function () { $("div.contentToChange").find("p").not(".alert").append("<strong class="addedtext"> This text "was" just appended to this paragraph</strong>") });
[code]....
In the return function (r) below, I cannot get the appended <tr> to slide down nicely. As it stands the <tr> just appears, which is fine but not the graceful effect I wanted. If I reinstate the hide() command it flickers crazily before appending.

I want to create a questions creation page. It has a Question Text Box and a Add Button.When users press the add button, there will be a newQuestion Text Box and a new Add Button appear in the next line. But the old Add Button will become a Delete Button and change its functionality.[code]I put all the Add Buttons and Minus Buttons into two different classes, ".buttonPlus" and ".buttonMinus".The .buttonPlus works well when the line is added by the main html. But it fails to work when it is added by the .append() function. It simply adds the .buttonPlus's CSS code to its button, but the$(".buttonPlus").click(function (event) {...} is NOT attached to the new buttonPlus.

I have a form which we append fields to when a user clicked a button. This is all working great.
However we need to be able to track and block when a user clicks the enter key.
We have the following code which works great when there is just one row of fields, however when we append the extra form it doesn't work on them...
$('.code').keyup(function(e) {
alert(e.keyCode);

I try to prepend/append code to the contents of a list item, but the contents are not in between the prepended and appended code..
the html:
<ul id="hoofdNavigatieLijst"><li>Collectie</li></ul>
the js:
$('ul#hoofdNavigatieLijst > li').prepend('<a href="/" class="klapOpen">');
$('ul#hoofdNavigatieLijst > li').append('</a>');
generated html code:
<li><a href="/" class="klapOpen"></a>Collectie</li>
how can I get the "</a>" to go to the end, after "Collectie"? I even put the <li> contents in a div, and tried it like this:
$('ul#hoofdNavigatieLijst > li > div').each(function() {
var ervoor = $(this);
var startlink = "<"+"a href="/xxx" class="klapOpen">"[code]....
does the same thing..when I replace the contents of the var's with normal words, they do wrap around the div, but when I use html code, they both go before the div, resulting in the same generated code as shown in previous post, plus the <div>-tags:
<li><a href="/" class="klapOpen"></a><div>Collectie</div></li>
I'm having a problem with Chrome and jQuery where I'm appending a script block to a page and I want the script to execute when it is appended. This works fine in every version of FF and IE I can find, but not in Chrome.
see the attachment for a simple example. In FF and IE you should get a 'hello world' alert when you click the page, but in Chrome you get nothing.
get Chrome to execute a script when the script is appended to a web page?

I dynamically generated some buttons, textboxes, radio (input types) etc using createElement method. The generation works fine. I append the newly generated input types to a span placed in the body. I want to make these draggable. I tried several ways of making the inputs draggable but none work. How do I make them draggable?

I have this HTML
HTML Code:
<ul id="my-list">
<li>item 1</li>
[code]....
I have the following HTML code which is doing a GET to a page, say
MyUrl.aspx :
<body>
<form name="form1" method="get" action="MyUrl.aspx" id="form1">
<input type="hidden" name="ClickedElement" id="Messenger" />
</form>
</body>
where the the Submit() is done within a javascript function invoked at
onclick on some element.
My question is: How can I prevent form submission when MyUrl.aspx is
not available? The javascript function is:
function Clicked(MyControl)
{
var _CellContent = document.getElementById("Messenger");
_CellContent.value = MyControl.id;
document.form1.submit();

View 2 Replies View RelatedI am creating this Javascript/XML HTA that is basically a project tracker. I recently added some new fields in the form that are written to the XML file for the project being tracked. This makes the files neither backwards compatible if I use it in a previous version nor forward compatible for future versions. This means if a user is using version 1, I create version 2, he wants to import his old tasks to Version 2, it throws an error. For example if I have a <status> element written in the newest version, but no <status> in the previous, I can no longer use that projects XML file in a previous version.
