Question

Here is the HTML code of a radio button

<input type="radio" class="grgrgrtgxxxxfeegrgbrg">

I am trying to check whether radio button’s name is having xx.
Here is my jquery code i have written

if($(this).prop('class').contains('xxxx'))
                               {
                                 alert("Yup");
                               }

Please tell me the Syntax mistake in it.

Answer 1

contains is a jQuery method that works with elements not with strings so you must use string methods:

if($(this).prop('class').indexOf("xx")>-1)
{
    alert("Yup");
}

But as someone else said you can use hasClass:

if($(this).hasClass("xx")) ...
