laravel5.4 +PHPoffice+Export.php 导出Excel表格

前端html代码:

<a href="#" id="Export"  class="inlineBlock operatBtn"><i class="icon-plus bigger-130"></i>
                导出
</a> 

Jquery:

var export_condition = {};
   $("#Export").click(function(){
        export_condition.time = $("#search2_time").val();
        export_condition.client = $("#search2_client").val();
        export_condition.username = $("#search2_user_name").val();
        export_condition.count = 0;
        export_condition.filename = "";
        result_export();
    });
   function result_export()
    {
        
        $.post("{{url('/log/log_export')}}",export_condition , function(data){
           // console.log(data);
            if(data.status === 1) {
                // $("#export_show").hide();
                layer.confirm('没有数据', {
                    btn: ['确定'] //按钮
                }, function () {
                    layer.closeAll();
                });
            } else if (data.status === 2) {
                package_file(data.filename);
            } else if (data.status === 3) {
                export_condition.count = data.count;
                export_condition.filename = data.filename;
                result_export();
            }
        });
    }
    

    function package_file(filepath)
    {
        //console.log(filepath);
        $.post("{{url('/log/actionPackage')}}", {filepath : filepath}, function(data){
            // $("#export_show").hide();
            if (data.status === true) {

                layer.confirm('导出完毕，是否下载？', {
                    btn: ['确定', '取消'] //按钮
                }, function () {
                    layer.closeAll();
                    window.location.href = "/storage/exports/" + data.filename;
                }, function () {
                });
            } else {
                layer.confirm('导出失败', {
                    btn: ['确定'] //按钮

                    layer.closeAll();
                });
