JavaScript time outs
Sometimes it’s necessary to repeat an action in JavaScript to check if something’s updated since last time the function was called:
window.setInterval(“goAjax()”,1000);
Sometimes things don’t immediately update in a browser so you may need to delay a function call using something like this:
var bVal = setInterval(“buttonValid();”,500);
and
clearInterval(bVal);
Functions/statements must be in quotes. Timings are in milliseconds.
Using setInterval() to Make a JavaScript Listener explains what this means and how to set and clear intervals.
