我在我的代码中遇到了一个障碍,下面的代码是一个完美运行的 JavaScript 时钟:
function renderTime() {
var currentTime = new Date();
var diem = "AM";
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
if(h == 0) {
h = 12;
} else if(h > 12) {
h = h - 12;
diem = "PM";
}
if(h < 10) {
h = "0" + h;
}
if(m < 10) {
m = "0" + m;
}
if(s < 10) {
s = "0" + s;
}
var myClock = document.getElementById('clockDisplay');
myClock.textContent = h + ":" + m + ":" + s + " " + diem;
myClock.innerHTML = h + ":" + m + ":" + s + " " + diem;
myClock.innerText = h + ":" + m + ":" + s + " " + diem;
setTimeout('renderTime()',1000);
}
renderTime();
但是,我现在尝试这样做略有不同:
function makeTime() {
var currentTime = new Date();
var diem = "AM";
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
if(h == 0) {
h = 12;
} else if(h > 12) {
h = h - 12;
diem = "PM";
}
if(h < 10) {
h = "0" + h;
}
if(m < 10) {
m = "0" + m;
}
if(s < 10) {
s = "0" + s;
}
var clock = document.getElementById('clock');
clock.innerHTML = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
myClock.textContent = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
myClock.innerText = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
setTimeout('makeTime()',1000);
}
makeTime();
这个有效,但是不像另一个那样更新,您必须手动刷新页面。
我究竟做错了什么?
