时间：

var now = new Date();
var dateEle = document.getElementById("date");
console.info(now);
console.info(now.getDate());
console.info(now.getMonth()+1);
console.info(now.getFullYear());
html = "";
setInterval(function(){
    var now = new Date();
    str = now.getFullYear() + "/"
            + (now.getMonth()+1) + "/"
            + now.getDate() + " "
            + now.getHours() + ":"
            + now.getMinutes() + ":"
            + now.getSeconds() + "";
    dateEle.innerHTML = str;
},1000);
