AJAX to PHP Sending A Value

Question

var studno = $('#studno').val();
$(document).ready(function () {
    $('.go').click(function () {
        $('.inup').load('prochat.php', {
            studno: studno
        });
    });
});

I have this code and it's supposed to send the value of studno into prochat.php but everytime it does it only says undefined. Can anyone explain?

add alert(studno) before $('.inup').load('prochat.php', studno:studno});, what value is in the alert? — slash197

you are basically reading the value once, when the script loads, that's why there is no #studno element yet, so you keep getting undefined.. — Dany Khalife

Try this:

$(document).ready(function(){
    $('.go').click(function(){
        var studno = $('#studno').val();
        $('.inup').load('prochat.php', {studno:studno});
    });
});

Thanks for the answer. I'll just accept it when after 11 minutes (cause that's what stack overflow says. lol)

This will always pass the same value though

Never mind. Turns out this works

$('.inup').load('prochat.php', {studno: $('#studno').val()});

These could be possible reasons:

at the line where you are assigning the value to studno, the value of studno might be undefined
#studno is not defined in the html

possible solutions:

-. try assigning the value within the click function:

like this:

$('.go').click(function(){
    studno = $('#studno').val();
    $('.inup').load('prochat.php', {studno:studno});
});

-. make sure that the element with id studno exists in the html document

This should work better:

$(document).ready(function () {
    $('.go').click(function () {
        $('.inup').load('prochat.php', {
            studno: $('#studno').val()
        });
    });
});
