模态不会触发5秒钟之后

Question

有人可以看到我在这里做错了什么吗？我希望在5秒钟的无活动中能够自动弹出式弹出窗口，但似乎不起作用。

这是我的JQ

var THRESHOLD = 5 * 1000;
var lastActive = Date.now();
$(window).ready(function() {
    if (Date.now() > lastActive + THRESHOLD) {
     $('#modal').fadeIn(1500).css('display','block').trigger('click');
    }
    lastActive = Date.now();
});

使用此代码，如果用户没有浏览器上的任何活动
