jQuery "not contains" selector

Solution 1:

Assuming your user's text is stored in a variable called userString:

$(':not(:contains('+ userString +'))').hide();

will hide all of the elements not containing that string.

Edit: If you have control over the elements in the list items, you could transform the user's text when you store it in the userString var.

Let say that you want the list of all <td> that dont contains string 'Dinesh'.(assuming Dinesh is inside name Attribute)

$('tableId > tbody > tr > td').not("[name*='Dinesh']")
