Posted 2020-09-22 相忘谁先忘

$(function(){
    $(‘#button1‘).click(function(){
         $.ajax({
             type: "POST",
             url: "eventlog.do",
             data: {methods:‘export‘},
             dataType: "json",
//访问之前的操作
             beforeSend:function(){
                 $("loading").show();
                 $("#button1").attr({ disabled: "disabled" });
                 document.forms[0].submit();
             },

//访问成功的回调函数

success: function(data){ alert(data+"success!"); },

//访问之后的操作

complete: function () { $("loading").hide(); alert("complete!!"); $("#button1").removeAttr("disabled"); }, }); }); });
