Get value of an text input defined by variable using jQuery

Question

I'm trying to get the value of an input text field using

var $rel = '#'+$(this).attr('rel');

but it returns nothing when I test it with

alert($rel.val());

Example: http://jsfiddle.net/59VmX/

Just use this.rel instead of $(this).attr('rel') and wrap it in jquery to get val(). — PSL

Don't forget to include the jquery library in the Frameworks & Extensions when using jQuery with jsFiddle. — Dylan Holmes

'#'+$(this).attr('rel');  // This is just a string

supposed to be

$('#'+$(this).attr('rel'));  OR // $('#'+ this.rel);

You need to encase it as a jQuery object if you want to use val method on the object

Or even better: $('#' + this.rel)

@Itay. According to the code the OP provided, I believe he was trying to access a input with id of that rel attribute.

When I try to do an alert to test it, there is no value. Updated: jsfiddle.net/59VmX/6

That is because you do not have a input that has the id set to the rel attribute

Check this jsfiddle.net/59VmX/8.. Also make sure you select the jQuery framework in options on left.

Remove the .val() Try just alert($rel);

Here is a working fiddle , In your old fiddle ,jquery is not loaded and:

Instead of this :

 var $rel = '#'+$(this).attr('rel');
 alert($rel.val());

It should be :

 var $rel = $(this).attr('rel');
 alert($rel);
