Determine if every radio group has had an option selected

Question

I need to make sure that all the radio groups have been answered before I enable the submit button. If I have:

var radioBtns = $(\'input\').filter(\':radio\         


        

Answer 1

not very neat way but still you can use it

$("input:button").click(function(){
    var v =$('input[name="a"]').filter(':checked');
    var vr =$('input[name="b"]').filter(':checked');
    if(v.length==0)
    {
    alert("select a group");

    }else alert("very good");


    if(vr.length==0)
    {
    alert(" o come on ");

    }else alert("guud");

    });
