显示星期几，小时和分钟以及日期

Question

我想调整此脚本，以便它还可以显示星期几和日期。

(function () {
    function checkTime(i) {
        return (i < 10) ? "0" + i : i;
    }

    function startTime() {
        var today = new Date(),
            h = checkTime(today.getHours()),
            m = checkTime(today.getMinutes());
        document.getElementById('time').innerHTML = h + ":" + m;
        t = setTimeout(function () {
            startTime()
        }, 500);
    }
    startTime();
})();

我虽然添加了getDay();，但我不知道如何在功能中添加它来说实话。知道日期和日期必须在页面上自动更新，这将持续数天......（这是一个几乎总是保持开启的显示。）

有什么想法吗？

Answer 1

dayNames = ["DOM", "LUN", "MAR", "MER", "GIO", "VEN", "SAB"],

dayNames[date.getDay()]

显示您当天的字符串。

将月份和日期名称添加到数组，然后使用getDay()，getDate()，getMonth()和getFullYear()：

＆＃13;

(function () {
    function checkTime(i) {
        return (i < 10) ? "0" + i : i;
    }

    function startTime() {
    	var months = [ 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December' ],
      	  days = [ 'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday' ]
    
        var today = new Date(),
            d = today.getDay(),
            f = today.getDate(),
            m = today.getMonth(),
            y = today.getFullYear(),
            
            h = checkTime(today.getHours()),
            i = checkTime(today.getMinutes());
        
        var val = days[d]+', '+f+' '+months[m]+' '+y+' - '+h+':'+i;
        
        document.getElementById('time').innerHTML = val;
        
        t = setTimeout(function () {
            startTime()
        }, 500);
    }
    
    startTime();
})();

＆＃13;

<div id="time"></div>

＆＃13;

＆＃13;

使用以下代码并进行检查。 HTML

 <div id="time"></div>
  <div id="day"></div>

<强>的Javascript

(function () {
    function checkTime(i) {
        return (i < 10) ? "0" + i : i;
    }

    function startTime() {
    var today = new Date(),
    ndays = [ 'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday' ]
    h = checkTime(today.getHours()),
    m = checkTime(today.getMinutes());
    s = checkTime(today.getSeconds());
    dn = today.getDay(),

    document.getElementById('time').innerHTML = h + ":" + m + ":" + s;
    var d=ndays[dn];
    document.getElementById('day').innerHTML=d;
    t = setTimeout(function () {
    startTime()
        }, 500);
    }
    startTime();
})();
