Ajax in jquery Post submitted in IE Chinese garbled solution _ajax related

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

Introduction of the problem:

Copy Code code as follows:

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 the Ff/chrome, the normal transmission of Chinese, but in IE, there are problems, in the background output information for garbled.

Questions to try:

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

2. Re-check the JSP page where the Ajax code resides, all for the use of utf-8, but the problem persists

3. In the background Java code, the forced use of Utf-8, GBK, gb2312 encoding conversion, the problem persists

After analysis, it may be related to the content transmission in the browser or jquery, and can not be accurately determined at present.

Solutions:

Anterior segment: encodeURI ($ (DOM). Val (), "UTF-8"); Using encodeURI for encoding

Back-end Java code:

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

Summarize:

Finally, it is possible to display the Chinese language correctly with the string information passed over to the Ajax POST request.
