Need help with JavaScript library "JQuery"

**windows_user** · 28-11-2008

I seek your help with the JavaScript library "JQuery". My goal is to recover a portion of the contents of a variable that contains HTML.

For example:

HTML Code:

var data = "<html> <head .............</ html>";

My goal is to recover (to put in a variable) an element whose id = 'foo' for example.

If you have any ideas, please help!

According to me, it is

$ ('foo')

Sorry but no.

$ ('foo') with prototype or $ ( '# foo') with JQuery retrieves the element if the damage is loaded. Basically, HTML is in the current page.

My problem is different because the HTML code is in a variable.

From this document: http://docs.jquery.com/Core

HTML Code:

$ (my_var ).$ ('# foo ')

I did not succeeded with your method. However, reading the document more closely, I read: "Create DOM elements on-the-fly".

The solution to my problem is here: http://docs.jquery.com/Core/jQuery# htmlownerDocument

A small example of implementation

Code:

$ (). ready (function () { 
$ ( "# mylink"). click (function () { 
var mycodehtml = "<p> my para <span id='foo'> <strong> Myfoo </strong> </span> </p>"; 
var foo = $ ( "# foo", mycodehtml). html (); 
alert (foo); 
}); 
});

HTML Code:
