Thinkphp3.2.3整合PHPexcel进行导入导出操作

前端按钮
<a class="button excel" _href="{:U(CONTROLLER_NAME.'/excel')}">导出Excel</a>

AJAX提交
$(function () {
    $(".excel").on("click",function () {
      var data = $(".inputcheckbox:checked").map(function (i,e){return $(e).val()}).get().join(','),
    _url = $(this).attr("_href");
$.post(_url,{data:data},function(data){
      if (data.status) {
          window.location.href = "{:U(CONTROLLER_NAME.'/excel')}/excid/"+data.excid;
     }
      },'json');
  });
})

控制器方法：
//导出excel
