Menu
Just trying to change the value of an input using jQuery. Seems to work, however, when I look at the value of #input using Firebug, it remains at the original value. Is this normal, or am I doing something wrong? Thank you

Use .val(): console.log( $('#input').val() );
$(function(){
$("#DoIt").click(function(){
$('#input').val('final');
console.log($('#input').val()); // the fixed line!
alert($('#input').val());
});
});

EDIT
Now I understand at what you are looking: inside the element source (inspect element) in Firebug.
Well, if you want to see the change actually happen you'll have to use:
$('#input').attr('value','final');
instead of:
$('#input').val('final');
otherwise the change is stored by the browser (nothing to be afraid of) but not updated by Firebug.
in this demo you can see it working:
$("#DoIt").click(function(e){
$('#input').attr('value','final'); // use .attr() to see the change happen in Firebug!
// $('#input').val('final'); // but rather use this
// $('#input').prop('value','final'); // or better THIS one!
console.log( $('#input').val() );
alert( $('#input').val() );
return false;
});
