地址前面添加encodeURI()

 var url = encodeURI('xxxAction.action?para='+中文);

 $('#cc').combobox({

     url : url,

     editable : false,

     valueField : 'cityId',

     textField : 'cityName'

 });

  // 打印报表

     function printReport(obj) {

         var url = encodeURI("@Url.Action(ViewBag.Print, "Report")?Year=" + $("#Year").val() + "&Month=" + $("#Month").val() + "&caseStatus=" + $("#casetypelist").val());

         obj.href = url;

             return true;

         }
