Question

Here’s the problem, in abstract terms: i have three input fields (A, B, C). two of them need to be text inputs (A and B), the third is of irrelevant type. I need to enable the third if A is not empty and B is not empty. I need to disable C if A is empty or B is empty.

The code

// empty is the empty function from the phpjs project
// framework used: jQuery
// A, B and C are classes here

$(".A, .B").keypress(function(){
   if( !empty($(".A").val()) && !empty($(".B").val()) )
       $(".C").attr("disabled","");
   else
       $(".C").removeAttr("disabled");
});

I want to be able to check this on keypress, but when requesting the value of the input that is edited when the keypress event occurs i get the value that was calculated before the keypress event.

Has anybody stumbled upon this before and solved it?

Answer 1

have you tried using the keyUp event?
