后台字符串转化成json

 function remotecontrol() {
     var progressbar = $("#progressbar");
     $.ajax({
         url: myurl,
         type: mytype,
         data: mydata,
         contentType: commonType,
         dataType: jsonType,
         success: function (data) {
             var ret = data.d.replace(/\r\n/ig, "<br \/>");
             var obj = eval('(' + ret + ')'); //转换后的JSON对象
             //if (obj.success) {
             progressbar.progressbar("value", 100);
             $('#dlgprogress').dialog('close');
             inittabled(obj);
             $('#dlg').dialog('open').dialog('setTitle', '操作结果');
         },
         error: function () {
             $('#dlgprogress').dialog('close');
         }
     });
