[SOLVED] Check whether specific radio button is checked

Check whether specific radio button is checked

I'm having trouble after looking at the jQuery docs. I'm just trying to return true/false in one my my jquery methods depending on the check of a certain radiobutton and if it's selected or not

I've tried several things but have not been able to get this right:

<input type="radio" runat="server" name="testGroup" id="test1" /><label for="<%=test1.ClientID %>" style="cursor:hand" runat="server">Test1</label>
<input type="radio" runat="server" name="testGroup" id="test2" /><label for="<%=test2.ClientID %>" style="cursor:hand" runat="server">Test2</label>
<input type="radio" runat="server" name="testGroup" id="test3" /> <label for="<%=test3.ClientID %>" style="cursor:hand">Test3</label>

and in my method I have this:

return $("input[@name='test2']:checked");

I'm getting an undefined on $("input[@name='test2']:checked");

UPDATED:

example:

<input type="radio" runat="server" name="radioGroup"  id="payPalRadioButton" value="paypalSelected" />

this returns 'undefined' still:

$("input[@name=radioGroup]:checked").attr('payPalRadioButton');

If I try this, I get 'false' even if I select the radio button:

$('input:radio[name=radioGroup]:checked').val() == 'paypalSelected'

Solution

Your selector won't select the input field, and if it did it would return a jQuery object. Try this:

$('#test2').is(':checked');
