Regex in ajaxPrefilter of JSON data type should not be valid

[Soul_Master@…]

jQuery.ajaxPrefilter( "json jsonp", function( s, originalSettings, dataIsString /* internal */ ) {

    dataIsString = ( typeof s.data === "string" );

    if ( s.dataTypes[ 0 ] === "jsonp" ||
        originalSettings.jsonpCallback ||
        originalSettings.jsonp != null ||
        s.jsonp !== false && ( jsre.test( s.url ) ||
                dataIsString && jsre.test( s.data ) ) ) {

From the above code, jQuery use jsre Regex to test current data. It return true when my data contain "?" symbol that is cause of bug when it process callback data as script instead of Json. The following code is my Json result that is generated by .NET JSON serializer. It can be correctly parsed when parser is parseJSON function instead of globalEval function.

{"ErrorList":{},"IsComplete":true,"RedirectTo":null,"ResultData":null}

Thanks,

For more information, my current data of this AJAX is the following code.

s.data = "ID=ec833bf0-6f8a-4899-921e-f7cfa725ca4b&ProcessID=ba2746c6-82ae-4f77-8e54-2654a736e398&CreatedDate=25+%E0%B8%A1.%E0%B8%84.+2554&Side=3&OwnerID=805e298e-6700-4629-a7cf-2f94916eac6a&Status=1&AttachedDocID=c72af5fd-41cc-4da4-83f3-689867a1b272&Description=fsyiul%3Blm.%2Cm&FileName=%3F%3F%3F2.jpg&CourtLevel=1"

Fixes #8054 by reverting feature enhancement 5812 (4920). Regexps no longer searches for %3F in url or data to find jsonp callback placeholders.

Changeset: 325dcdc2ab05173f809b9d83af59918b3695cc23

(In #5812) This enhancement breaks legitimate uses of ? in url or data.
