then my code is not worked so how can i define a variable in jquery

Answer 1

jQuery is just a javascript library that makes some extra stuff available when writing javascript - so there is no reason to use jQuery for declaring variables. Use "regular" javascript:

var name = document.myForm.txtname.value;
alert(name);

EDIT: As Canavar points out in his example, it is also possible to use jQuery to get the form value:

var name = $('#txtname').val(); // Yes, it's called .val(), not .value()

given that the text box has its id attribute set to txtname. However, you don't need to use jQuery just because you can.

Answer 2

Try this :

var name = $("#txtname").val();
alert(name);
