<div id="timeDiv"></div>var timeDiv = document.getElementById('timeDiv');function addZero(value){        return value < 10 ? "0" + value : value;}function getTime(){        var time = new Date();        var year = time.getFullYear();        var month = time.getMonth() + 1;        var day = time.getDate();        var hour = time.getHours();        var minus = time.getMinutes();       var second = time.getSeconds();     var week = time.getDay();        var area = '日一二三四五'       timeDiv.innerHTML = year +"年"+addZero(month)+"月"+addZero(day)+"日 星期"+area[week]+addZero(hour)+"时"+addZero(minus)+"分"+addZero(second)+"秒"}getTime()window.setInterval(getTime, 1000)
