我有这个应该显示时间的 javascript 代码。有用。不过,我不想增加额外的时间。假设我想增加 1 小时。
<script type="text/javascript">
Date.prototype.addHours = function(h) {
this.setTime(this.getTime() + (h*60*60*1000));
return this;
}
// This function gets the current time and injects it into the DOM
function updateClock() {
// Gets the current time
var now = new Date();
// Get the hours, minutes and seconds from the current time
var hours = now.getHours();
var minutes = now.getMinutes();
var seconds = now.getSeconds();
// Format hours, minutes and seconds
if (hours < 10) {
hours = "0" + hours;
}
if (minutes < 10) {
minutes = "0" + minutes;
}
if (seconds < 10) {
seconds = "0" + seconds;
}
// Gets the element we want to inject the clock into
var elem = document.getElementById('clock');
// Sets the elements inner HTML value to our clock data
elem.innerHTML = hours + ':' + minutes + ':' + seconds;
}
function start(){
setInterval('updateClock()', 200);
}
</script>
第一个函数计算我要添加的毫秒数,第二个函数是“实时时钟”。如何将第一个功能实现到第二个功能中,以便获得工作结果?
最佳答案
要增加小时数,请使用 setHours
:
// Gets the current time
var now = new Date();
console.log("actual time:", now);
now.setHours(now.getHours() + 1)
console.log("actual time + 1 hour:", now);
