<!--标题变成时钟-->
<div id="Header1_HeaderTitle"></div>
<script>
    function get_time() {
        var obj = new Date();
        var hour = obj.getHours();
        var min = obj.getMinutes();
        var seconds = obj.getSeconds();
        if (parseInt(seconds)<10)seconds='0'+seconds;
        if (parseInt(hour)<10)hour='0'+hour;
        if (parseInt(min)<10)min='0'+min;
        var time = hour + '时' + min + '分' + seconds + '秒'
        var title = document.querySelector('#Header1_HeaderTitle')
        title.innerText = time
    }
    setInterval('get_time()',1000)
    setInterval(function () {
        console.log(1)
    },1000)
