• 3 val() is for form fields. Are you looking for html()? – Tim M. Commented Oct 3, 2012 at 7:54

You need to pass the value of this, not a string "this", to jQuery, and call .text() to get the text content of an element, not .val() (which gets the value of an input element):

$('input').on('change',function(){
    var x = $(this).parent('div').text(); //`text` method gets contents of div
    //        ^ no quotes around `this`
    alert(x);
})​​​;

Corrected Script

$('input').on('change',function(){
  var x = $(this).parent('div').html();
  alert(x);
})​​​;

• val() is for form fields only
• this should not be quoted.

Alternative

If you only want the text of the parent, you can use text(). However, browsers can differ on how they implement it (see the notes here). In this case, it's probably cleaner to wrap the content you want in another element, like:

<div>
  <span>my content of the div1</span>
  <input/>
</div>​

And use script like:

$('input').on('change',function(){
  var x = $('this').siblings("span").html();
  alert(x);
})​​​;

You can ge the contents of the div with .html(), not with .val() method. The .val() method is primarily used to get the values of form elements such as input, select and textarea. See here for details.

jQuery val() only works on inputs not on generic html elements.

Change $('this') to $(this). (remove the quotes).

.val() doesn't exist for others tags than select/input/textarea tags. I'll suggest that you use .text() function or .html(), depending on what you would like to retrieve.

your code should be like this

$('input').on('change',function(){
  var x = $(this).parent('div').text();
// OR var x = $(this).parent('div').html();
    alert(x);
})​​​;

use this

$('input').bind('keyup',function(){ 
alert($(this).parent().html());
})
