今天根据客户要求做了个导出功能，客户选择订单，导出的是该订单的产品明细
注意：在逗号拼接字符串的时候我老是忘了截取最后一个逗号
function exportproduct(){
var checkStatus = table.checkStatus('orderList');
if(checkStatus.data.length > 0){
var ids ="";
for(var i in checkStatus.data){
ids+=(checkStatus.data[i].id + ",");
}
ids = ids.substr(0, ids.length - 1);
var url='${pageContext.request.contextPath}/order/exportProduct.action?ids='+ids;
$("#downloadFrame").attr("src",url);
}else{
layer.open({
icon: 2,
title: '操作失败',
content: '请先勾选要导出的订单'
});
}
}
public void exportProduct(String ids, HttpServletRequest request, HttpServletResponse response) throws Exception {
