jquery how to make sure that all the images has been loaded

var nowCount = 0;
$("img").load(function(){
imgCount++;
if (nowCount == imgsCount)
do something ... 
});

imgsCount :: the number of images that i want 开发者_StackOverflow中文版to load

1- is this code compatible with all browsers ?

2- how can i know if an image failed to load ?

There is a lot of suspicious code here:

• ImgsCount vs. ImgCount
• what is nowCount supposed to do?
• Are you sure about the unload event for the IMG tag?

If you want to load images in the background, you need to create a new image element and attach a source attribute.
