How to show a spinner while loading an image via JavaScript

by

I’ve used something like this to preload an image and then automatically call back to my javascript when the image is finished loading. You want to check complete before you setup the callback because the image may already be cached and it may not call your callback.

function PreloadImage(imgSrc, callback){
  var objImagePreloader = new Image();

  objImagePreloader.src = imgSrc;
  if(objImagePreloader.complete){
    callback();
    objImagePreloader.onload=function(){};
  }
  else{
    objImagePreloader.onload = function() {
      callback();
      //    clear onLoad, IE behaves irratically with animated gifs otherwise
      objImagePreloader.onload=function(){};
    }
  }
}
