Checking Existence Of An Element?

Jul 20, 2005

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?

Checking If Span Object(s) Exist

Jul 20, 2005

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.

JQuery :: Getting Id Value With # Appended?

Apr 27, 2010

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.

JQuery :: Appending To Appended Elements?

Nov 18, 2010

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.

JQuery :: Cannot Get The Appended <tr> To Slide Down Nicely

JQuery :: Add A Function To Appended Html Strings?

Oct 7, 2011

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.

JQuery :: Contents Are Not In Between The Prepended And Appended Code?

Aug 27, 2009

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>

How To Check URL Existence ?

Aug 24, 2006

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();

Validating Existence Of XML Tag ?

Apr 13, 2011

I 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.

I tried to use the following code to validate existence of the tag and assign whatever outcome as the variable to write, but it's not working. Theres a few different ways I tried.

1st Way:

Code:

2nd Way:

Code:

3rd Way:

Code:

Here's the XML file for reference.
