Question

I’m trying to make some code which finds if a div exists, and if it does then have it fade away slowly. I have this to determine whether or not the div exists

    if($('#error').length != 0)
 {
  $('#error').hide(500);
 }  

And that does work but only on a refresh, I’ve been attempting to put it in a timer like this:

   var refreshId = setInterval(function()
   {
      if($('#error').length != 0)
 {
  $('#error').hide(500);
 }   
   }, 500);

But its not getting rid of the innerHTML! I have some code which on hover alters the innerHTML of the error div so I can fill it up, but for some reason this isn’t working, any advice would help!

Thank you!

Answer 1

$("#error").fadeOut(500);

Update:

If you are looking to check for existence:

var msg = $("#error");
if(msg.length) {
  msg.fadeOut(500);
}

If you want to empty it:

$("#error").empty();
