Question

How can I call a JavaScript function when a div’s display is set to none?

This is the code I have :

if(document.getElementById("myDiv").style.display == "none"){

myFunction();

}

I was thinking having a function that repeats everytime (similar to an actionscript ENTER_FRAME event) with the if statement within it but i imagine that would ass a lot of lag.

Sorry if Im not clear enough.

Answer 1

I can think of 2 options.

1. What you have above being called with setInterval.

Or

1. Since you’re waiting on a programatic event, why don’t you call myFunction the same time you show myDiv?
