Implementation method of using Flash to read cross-domain data in Ajax_javascript skills

Cross-domain operation of Ajax has always been a problem. The current main solutions are:
　1. JSONP (needs to be supported on the server side)
　2. IFrame (can only operate between subdomains)
3. Page proxy (this is a bit universal)
4. Access-Control-Allow-Origin (supported by new browsers, you need to set the Header on the server side)
Today, I provide another way to use Flash for cross-domain operations. method. As we all know, there are actually limitations to Flash's cross-domain operations. However, Flash's cross-domain configuration is relatively simple. You only need to place crossdomain.xml in the root directory of the site. As for the usage of crossdomain.xml, you can read this article: http://www.jb51.net/article/25485.htmThis article.
For this series of operations, I have encapsulated it in the form of a jQuery plug-in, and the download address will be attached at the end of the article.
How to use:
1. Introduce jQuery and ajaxf.js files into the page.
2. Insert the following code on the page. First install Flash into the page.

Copy code The code is as follows:

$(document).ready(function() {
$.ajaxf.install('/Files/zsea/flash4ajax.swf');
});

　3. Call the method to obtain remote data.

Let’s talk about the methods provided by the plug-in in detail:
$.ajaxf.install(swfpath)
To install Flash to the page, you can specify the path of Flash.
　$.ajaxf.ready(function(){})
　The function executed after Flash is loaded.
　 $.ajaxf.isReady()
Returns whether Flash has been loaded. The return value is Boolean
　 $.ajaxf.ajax(p)
　 Native ajax call support, p is an object, including: callback, callback function; type, method type, supports json, text, xml, script; url, the address to read the data; method, the request method, supports get, post; data, the data sent; contentType, the contentType header of the request; header, Object object, additional request headers.
　 $.ajaxf.get(url, data, callback, type)
　 Get data through get method
$.ajaxf.post(url, data, callback, type)
Get data through post method
Everyone knows the meaning of the following names just by looking at them, so I won’t explain them too much
$.ajaxf.getText(url, data, callback)
$.ajaxf.getJSON(url, data, callback)
$.ajaxf.getScript(url, data, callback)
$.ajaxf.postJSON(url, data, callback)
$.ajaxf.postText(url, data, callback)

Let’s demonstrate how to obtain the HTML code for Youku’s homepage.

Copy code The code is as follows:

Unfortunately, I don't know how to run the code on the page in the garden. Only friends have tested it themselves.
