ajaxSubmit插件jQuery1.4.2版JSON问题

jQuery Form 插件基于jQuery v1.4.2版返回JSON数据时一直报错；修改以下内容可恢复；

原后台输出数据格式如：{sitename:'开发者网络',siteurl:'ww***AA.net',level:10} 需改为 {"sitename":"开发者网络","siteurl":"ww***AA.net","level":10}

也就是在名称需以双引号包括；因为 jQuery 1.4.2版在 parseJSON 方法中添加了正则判断

if ( /^[],:{}s]*$/.test(data.replace(/\(?:["\/bfnrt]|u[0-9a-fA-F]{4})/g, "@")    .replace(/"[^"\nr]*"|true|false|null|-?d+(?:.d*)?(?:[eE][+-]?d+)?/g, "]")    .replace(/(?:^|:|,)(?:s*[)+/g, "")) ) {    // Try to use the native JSON parser first    return wi***w.JSON && wi***w.JSON.parse ?     wi***w.JSON.parse( data ) :     (new Function("return " + data))();   } else {    jQ***y.error( "Invalid JSON: " + data );   }

jQuery Form 插件需要修改的地方

if (scr || s.***tarea) {      // see if user embedded response in textarea      var ta = do***etElementsByTagName('textarea')[0];      if (ta) {       xh***esponseText = ta.value;      }      else if (scr) {       // account for browsers injecting pre around json response       var pre = do***etElementsByTagName('pre')[0];       if (pre) {        xh***esponseText = pr***nnerHTML;       }      }         }     else if (s.***aType == 'xml' && !xh***esponseXML && xh***esponseText != null) {      xh***esponseXML = toXml(xh***esponseText);     }

修改为：

if (scr || s.***tarea) {      // see if user embedded response in textarea      var ta = do***etElementsByTagName('textarea')[0];      if (ta) {       xh***esponseText = ta.value;      }      else if (scr) {       // account for browsers injecting pre around json response       var pre = do***etElementsByTagName('pre')[0];       if (pre) {        xh***esponseText = pr***nnerHTML;       }else xh***esponseText=doc.body.innerHTML;      }         }     else if (s.***aType == 'xml' && !xh***esponseXML && xh***esponseText != null) {      xh***esponseXML = toXml(xh***esponseText);     }
