Ajax post in jquery to submit garbled solution (GO)

Introduction: In jquery Ajax POST request, the request, the Chinese in the background, the display as garbled, how to solve it?

Introduction of the problem:

var Regid = $ (' #oregion '). ComboBox (' GetValue ');

var sname = $ (' #sname '). Val ();

var sname = encodeURI ($ (' #sname '). Val (), "UTF-8");

if (regid!= "" &&regid!= ' undefined ') {

$.ajax ({

Async:true,

Type: "POST",

DataType: "JSON",

URL: "<%=request.getcontextpath ()%>/secretary/ishasuser.do?regid=" +regid+ "&sname=" +sname,

Success:function (data) {

if (data.mes!= "" &&data.mes!=null) {

$.messager.alert (' Warning ', data.mes);                              

return false;

}

}

});

}

}

The above code in Ff/chrome, can be normal delivery of Chinese, but under IE, there is a problem, in the background output information is garbled.

Problem attempts:

1. Set the ContentType: "Text/plain; Charset=utf-8 ", the problem still exists

2. Recheck the JSP page where the AJAX code is located, all using Utf-8, but the problem persists

3. In Java code in the background, forcing the use of Utf-8, GBK, gb2312 encoding conversion, the problem remains analyzed, it may be related to the browser or jquery content transmission, and currently can not be accurately determined.

Workaround : Previous paragraph: encodeURI ($ (DOM). Val (), "UTF-8"); Encode using encodeURI

Back-end Java code:

Urldecoder.decode (Inputstr, "UTF-8"): The back-end code decodes the string passed over the previous paragraph.

Summary: Finally, you can send the string information to the Ajax POST request, the normal display of Chinese.
