Halo theme mjolnir mix php+AJAX solution to the problem that sending Chinese will cause garbled characters

//If the transmission parameters are given directly, garbled characters will be generated!

Copy the codeThe code is as follows:

http_request.open("POST",url,true);
http_request.setRequestHeader('Content- Type', 'application/x-www-form-urlencoded');
http_request.send("action="+strName+"&val="+val); //If the value of val is Chinese, garbled characters will be generated

//The solution is very simple: use the escape(string) function in javascript

The simplest solution to the garbled Chinese characters in the ResponseText GET returned in AJAX
When using AJAX to GET back a page, most of the Chinese characters in the RESPONSETEXT will appear garbled. This is because when xmlhttp processes the returned responseText, The resposeBody is encoded in UTF-8 and decoded. If the server sends a UTF-8 data stream, the Chinese characters will be displayed correctly, but when the GBK encoded stream is sent, it will be messed up. The solution is to add a HEADER to the sent stream to indicate what encoding stream is sent, so that XMLHTTP will not mess up.

Copy codeThe code is as follows:

PHP:header('Content-Type:text/html;charset=GB2312');
ASP:Response.Charset("GB2312")
JSP:response.setHeader ("Charset","GB2312");
