js implements display time and date instance

This article mainly brings you an example of js displaying date and time (the time increases by 1 after one second). The editor thinks it is quite good, so I will share it with you now and give it as a reference for everyone. Let’s follow the editor to take a look, I hope it can help everyone.

html：

<p id="data"><font>2017年10月17日 15:11:11</font></span>

js：

function showLocale(objD) {  

 var str, colorhead, colorfoot;  

 var yy = objD.getYear();  

 if (yy < 1900) yy = yy + 1900;  var MM = objD.getMonth() + 1;  

 if (MM < 10) MM = &#39;0&#39; + MM;  var dd = objD.getDate();  

 if (dd < 10) dd = &#39;0&#39; + dd;  var hh = objD.getHours();  

 if (hh < 10) hh = &#39;0&#39; + hh;  var mm = objD.getMinutes();  

 if (mm < 10) mm = &#39;0&#39; + mm;  var ss = objD.getSeconds();  

 if (ss < 10) ss = &#39;0&#39; + ss;  var ww = objD.getDay();  

 if (ww == 0) colorhead = "";  

if (ww > 0 && ww < 7) colorhead = "";

str = colorhead + yy + "年" + MM + "月" + dd + "日 " + hh + ":" + mm + ":" + ss + " ";

return (str);

}

function tick() {

var today;

today = new Date();

document.getElementById("new_data").innerHTML = showLocale(today);

window.setTimeout("tick()", 1000);

}

tick();
