我已经获得了一些JavaScript,可以创建一个数字时钟进入网页。这是完美的工作,但是我尝试修改它以在span或粗体标签中包装am / pm后缀(或此代码中的diem),以便我可以在CSS中将其设置为与其余时间不同的样式。
我确信对于那些知道他们正在做什么的人来说这真的很简单,但我真的很挣扎。任何帮助将不胜感激,JavaScript如下:
function renderTime() {
var currentTime = new Date();
var diem = "AM";
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
setTimeout('renderTime()',1000);
if (h == 0) {
h = 12;
} else if (h > 12) {
h = h - 12;
diem="PM";
}
if (m < 10) {
m = "0" + m;
}
if (s < 10) {
s = "0" + s;
}
var myClock = document.getElementById('clockDisplay');
myClock.textContent = h + ":" + m + " " + diem;
myClock.innerText = h + ":" + m + " " + diem;
var diem = document.createElement('span');
}
renderTime();

您有几个选择:
使用innerHTML代替innerText。这允许您将HTML标记插入到字符串中:
myClock.innerHTML = h + ":" + m + " <span>" + diem + "</span>;
使用appendChild并忽略innerText末尾的diem
:
myClock.innerText = h + ":" + m + " ";
var diemSpan = document.createElement('span');
diemSpan.innerText = diem;
myClock.appendChild(diemSpan);
最后,您可以在标记中添加clockDisplay
和diem
范围并适当地访问它们:
<强>标记:强>
<div id="clockDisplay">
<span id="clockDisplay-time"></span>
<span id="clockDisplay-suffix"></span>
</div>
<强>脚本:强>
document.getElementById("clockDisplay-time").innerText = h + ":" + m;
document.getElementById("clockDisplay-suffix").innerText = diem;
答案 1 :(得分:1)
试试这个:
var myClock = document.getElementById('clockDisplay');
var suffix = document.createElement('span');
suffix.innerText = diem;
myClock.innerText = h + ":" + m + " ";
myClock.append(suffix);
或者,如果你想提高效率(纯DOM操作):
var myClock = document.getElementById('clockDisplay');
var suffix = document.createElement('span');
suffix.append(document.createTextNode(diem));
myClock.append(document.createTextNode(h + ":" + m + " "));
myClock.append(suffix);

Here's一个JSfiddle给你。它应该按照你想要的方式工作。
解决方案是为时间创建不同的跨度和“diem”,如下所示:
<强> HTML:强>
<p><span id="time"><!-- time will go here --></span><span id="diem"><!-- "diem" will go here --></span></p>
然后单独访问它们。您也可以在CSS中对它们进行不同的样式设置,如下所示:
<强> CSS:强>
span#diem {
font-weight: bold;
// your styles
}
<强> JS:强>
window.onload = function() {
renderTime();
}
function renderTime() {
// Insert time calculations here
var time_span = document.getElementById('time');
time_span.innerText = h + ":" + m;
var diem_span = document.getElementById("diem");
diem_span.innerText = " " + diem;
}
