Ajax Chinese garbled Problem and Solution

Use jquery's Ajax method to submit Ajax requests, CodeAs follows: 1 $. Ajax ({
2 datatype: 'json'
3, type: 'post'
4. url: 'http: // localhost/test. Do'
5, data: {ID: 1, type: 'item '}
6, success: function (data ){
7
8}
9}); problem: Background action after submission ProgramThe obtained type is garbled. Solution: Method 1: encodeuri is used for encoding twice before submission. Remember that it must be twice. modify the following code data: {ID: 1, type: encodeuri ('item')} 2. decode1string type = request for the obtained string in the background action. getparameter ("type ");
2 type = urldecoder. decode (type, "UTF-8"); Method 2: Ajax configure the contenttype attribute, add the following parameter 1 contenttype to the Ajax method with charset = UTF-8: "Application/X-WWW-form-urlencoded; charset = UTF-8" using other JS frameworks or xhr is similar, set the contenttype in the header, the key here is charset = UTF-8, if this parameter is not found, it cannot be found. By default, the contenttype in jquery does not exist. add that the parameter in jquery has been processed by encodeuricomponent. * method 2 does not require decode in the action. Therefore, this method is recommended.
