在几分钟内领先零 [英] Leading zeros in minutes

问题描述

我创建了一个时钟放在我网站的标题中。时间不显示零分钟< 10.例如，如果时间是10:50，它将只显示10：5，我找到了解决方案但不确定如何实现它。如果有更好的方法，请分享。

I created a clock to be placed in the header of my website. The time is not displaying a zero for minutes < 10. For example if the time is 10:50, it will only show 10:5 ,I found a solution but unsure of how to implement it. Also if there is a better method please share.

 var current;
window.onload = function () {

    current = new Date();

    document.getElementById("clock").innerHTML = current.getHours() + ":" +      current.getMinutes(); 

这就是我所需要的

                if (minutes < 10)
                minutes = "0" + minutes

这是我时钟的容器

    <span id="clock">&nbsp</span>

推荐答案

因为你可能会遇到表达问题未来沿着同样的路线，我建议为Javascript挑选一个最喜欢的字符串格式函数。

Since you're likely to run into presentational issues in the future along the same lines, I'd recommend picking a favorite string formatting function for Javascript.

一些例子：

• http：//www.masterdata .se / r / string_format_for_javascript /


• http ：//www.diveintojavascript.com/projects/javascript-sprintf

• http://www.masterdata.se/r/string_format_for_javascript/
• http://www.diveintojavascript.com/projects/javascript-sprintf

然后您可以执行类似<$ c的操作$ c>{0:00}：{1：00}。format（current.getHours（），current.getMinutes（））甚至更好，

Then you can do something like "{0:00}:{1:00}".format(current.getHours(), current.getMinutes()) or even better,

var d = new Date();
var s = d.format("hh:mm:ss tt");
// Result: "02:28:06 PM"
