This article mainly introduces the relevant knowledge of "how Ajax accesses XML data across domains". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how Ajax accesses XML data across domains" can help you solve the problem.

XML data cannot be read through Ajax cross-domain requests on the client by default. The general practice is to write a simple agent program on the server to read the remote XML data to the local server first, and then the client requests through Ajax from the local server. Since we cannot make any settings or modifications to the environment in which the data source is located, it is difficult to bypass this problem only through the client code. However, if the requested data is not a XML but a JSON object or JavaScript function, it can be easily solved by the JSONP method, and the returned result can be obtained by directly calling the JQuery.getJSON () method in the callback function. If you want to use JSONP, you can append the query parameter "& callback=?" to the specified URL.

$(document) Ready (function () {

$.getJSON ("http://www.example.com/getdata", function (data) {

Console.log (data)

})

})

$(document) Ready (function () {

$.getJSON ("http://www.example.com/getdata2?callback=?", function (data) {

Console.log (data)

})

})
