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