function exportCSV (argument) {
    //导出csv
    var url = "xxx";
    $.ajax({
        url: url,
        type: "POST",
        //data: $(‘#layui-form‘).serialize(),
        data: {
            "filter_platform":$("#filter_platform").val(),
            "filter_accoount":$("#filter_accoount").val(),
            "filter_project":$("#filter_project").val(),
            "export_cvs":"export_cvs"
        },
        beforeSend: function (xhr,settings) {
            xhr.setRequestHeader("X-CSRFtoken",$.cookie("csrftoken"));
            layer.msg(‘csv生成中,请等待......‘, {icon: 4,time:600000});
        },
        success: function (data) {
            if (data.code == 0){
                window.open("/static/xxx/download/" + data.file_name);
                layer.alert(data.msg, {icon: 6});
            } else {
                layer.alert(data.msg, {icon: 7});
            }
        },
        complete: function () {
            console.info("生成csv数据执行完成......");
        },
        error: function (data) {
            console.info("生成csv数据执行出错......");
