实现功能：java导出excel表
1、jsp代码
1 <form id="zhanwForm" action="<%=path%>/conferences.do?" target="_self" method="get" > 2 <input type="hidden" name="method" value="outData"/> 3 <input type="hidden" name="compassId" value='1'/> 4 <input type="hidden" name="fromWhere" value="AAAA"/> 5 6 </from>
2、js代码
1 $(".daochu1").click(function(){ 2 var bank = new Array(); 3 $.each($(".guangGaoLeiXing").find("input:checked"), function () { 4 bank.push($(this).val()); 5 }); 6 if(bank == false){ 7 alert("请选择要统计类型"); 8 }else{ 9 $("#zhanwForm").submit(); 10 } 11 }) 12 13 $(".lyBtn").click(function(){ 14 $(".mask").show(); 15 $(".tishiDiv").show(); 16 $.ajax({ 17 url : '<%=path %>/conferences.do?method=getUserLy&fromWhere=csco', 18 type : 'GET', 19 dataType : 'json', 20 success : function(data) { 21 $(".mask").hide(); 22 $(".tishiDiv").hide(); 23 window.open(data.url); 24 } 25 }) 26 });
3、action处理代码
