Overview
Available since tags 4.82.
You can use sb.script in order to dyanmically load additional javascript into the head of your document and have it execute. While you can esily use sb.ajaz for loading additional javascript on the same site, sb.ajax does not allow you to load data from another domain. To get around thisyou can use sb.script, however, you should be aware that this could be dangerous if you do not trust the 3rd party you are loading the javascript from.
sb.script returns an sb.element that represents the script tag which was dynamically created.
Properties
src
The src of the javascript data
charset
The charset defaults to UTF-8
type
Defaults to text/javascript
Methods
By default sb.script instances inherit all the methods of Element.prototype. It also standardizes onload for IE
onload()
Fires after the script has loaded and can be used to interact with the data in the script. It can also be used to remove the script data from the page after it has executed to prevent memory leaking in long lived scripts.
load()
Fetch the data from the src specified when creating the instance.
remove()
Removes the script from the DOM and cleans up the attributes in IE
Example
javascript code
var script = new sb.script({ src : 'http://someotherdomain.com/test/script', onload : function(){ //alert teh head before removing alert($('head').innerHTML); this.remove(); //alert it after alert($('head').innerHTML); } }); script.load();
