如何使用php和jquery发布跨域数据并获得响应

Im trying to create a bookmarklet that allows users to post a lot of cross domain data to a php script and get a response from the php script using jquery. What is the best way to do this

I recommend checking out JavaScript: Use a Web Proxy for Cross-Domain XMLHttpRequest Calls

Your best shot will be to use JSONP:

JSONP or "JSON with padding" is a complement to the base JSON data format, a pattern of usage allowing a page to request data from a server in a different domain. JSONP is a solution to this problem, forming an alternative to a more recent method called Cross-Origin Resource Sharing.

jQuery implements JSONP. Try and test this code:

$.ajax( {
  url: 'http://…',
  dataType: 'jsonp',
  complete: function(xmlHttpReq, textStatus) {…}
});

Tricky because Cross Site Scripting gets blocked by most browsers. My solution was to write the data to a file and then access that file from php. Pass the data through a file in other words.
