紧急状况：jQuery ajax 回调不实施

$.ajax({
         type:'POST',
         dataType:'xml',
         async:false,
         url:'/module/reveice/default.php?'+ Math.random(),
         data:{action:'ReveiceAdd',ProjectID:ProjectID,IssueID:_UserID,Content:Content,Price:Price,Cycle:Cycle,File:File},
         success: function(dataXML){
            
             if($(dataXML).find('succeed').text()=='true'){
                             alert('Congratulations,the successful bid!');
                            $.cookies.set('fileSrc','');
                            window.location.href='/reveice/project/';
                            return;
                                }
             if($(dataXML).find('succeed').text()=='false'){
                            alert($(dataXML).find('info').text());
                            return;
                                }
                        alert('error !');
                 }
            });
