I got a very common question that I want to get the value of a HTML input by jQuery selector with its name and specific attribute like checked. Following is my case:

<input type="radio" name="gender" value="man" checked="checked" />
<input type="radio" name="gender" value="women"/>

I tried the following code:

var gener = $("name='gender':checked=checked").val();

But it didn't return a correct value. Hope somebody gives me help on it. Thanks.

You need to type the element then the attribute, like this $('element[attribute="value"]')

$('input[name="gender"]:checked').val();

With the :checked selector, you don't need to provide a value, try this:

var gender = $('input[name="gender"]:checked').val();

More information in the API docs

$('input[name="gender"]:checked').val();

Are you looking for something like that?
