javascript Document ready firefox (jQuery)

问题

In FireFox I have this jQuery at the end of the body:

$(document).ready(function() {
     $.getScript('LiveMapsJavascriptProvider.aspx?type=reference&value=6', init);
});

There are a lot of js files in the head that are needed to be all loaded before this would work. So I put my call in a document.ready event. It doesn't work. IE works fine.

If I put an alert(''); before I call $.getScript it works.

It looks like a problem with the scripts not getting loaded yet?

I thought Document.ready was fired after all the scripts are loaded and ready to go.

Thanks, ian

You don't necessarily need to use jQuery for that.

Simply have an onload function as below:

<body onload="JavascriptFunctionName">

Or you can dynamically attach your function call to the onload event as shown below:

function addEvent(obj, evType, fn){ 
 if (obj.addEventListener){ 
   obj.addEventListener(evType, fn, false); 
   return true; 
 } else if (obj.attachEvent){ 
   var r = obj.attachEvent("on"+evType, fn); 
   return r; 
 } else { 
   return false; 
 } 
}
addEvent(window, 'load', JavascriptFunctionName);

You may embed jQuery functions calls inside the JavascriptFunctionName function.

EDIT:

jQuery is also capable of doing that through the following code. I recommend trying that first, for the sake of avoiding unnecessary redundant code.

$(window).load(function() {
    JavascriptFunctionName();
});

回答2:

document.ready is fired after the DOM is loaded. You may try this:

$(window).load(function() {
    // will execute once all scripts and images are finished loading
});

You can try using something like head.js to specify execution order, while still taking advantage of parallel loading.
