Question

Neither of the alert box works for following code –

var genvalue=('input[#gender]:checked').val());
alert (genvalue);

var value = $("#edu_det1").val();
alert (value);

But when genvalue, the whole portion of code is remove it work. Don’t know what the problem

Answer 1

If you are trying to get an element with an ID, just target that ID as it should be unique :

var genvalue = $('#gender').val();
alert (genvalue);

var value = $("#edu_det1").val();
alert (value);

Otherwise you can also do :

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

But that sort of defeats the point of having an ID !
