Question

So referencing this:
How to delay the .keyup() handler until the user stops typing?

I came up with the following code. But it does nothing… Any suggestions?

I am trying to get the setTimeout to cancel if the user types something further, so that multiple alerts don’t happen, only one when the user finally ‘stops’ (hopefully).

Thanks!!

var t = 0;  
$('input').keyup(function(){
    clearTimeout(t);
    t = setTimeout(alert($('input').val()),1000);
}

Answer 1

Replace

t = setTimeout(alert($('input').val()),1000);

with

t = setTimeout(function(){alert($('input').val())},1000);

You were passing the value of the input to setTimeout, while setTimeout needs a function (or a string it can evaluate as code) as first argument.

And replace the last line with }); so that the code compiles.
