我有一个工作正常的javascript代码,但我希望在一个页面上有多个时钟。
例如,我需要3个时钟。
我不知道如何在getelementbyid
中具有多个ID?
<div id="time">October 25, 2018 18:00 GMT+0300 (CDT)</div>
var timestamp = document.getElementById('time'),
t = new Date(timestamp.innerHTML),
hours = t.getHours(),
min = t.getMinutes() + '',
months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];
if(min.length == 1) min = '0' + min;
timestamp.innerHTML = hours + ':' + min ;
最佳答案
这里的每个人都在正确的答案上,我只是认为,如果您看到一些代码来引用他们的言论,那将会有所帮助
var timestamp1 = document.getElementById('time1')
getTime(timestamp1)
var timestamp2 = document.getElementById('time2')
getTime(timestamp2)
var timestamp3 = document.getElementById('time3')
getTime(timestamp3)
function getTime(obj){
t = new Date(obj.innerHTML),
hours = t.getHours(),
min = t.getMinutes() + '',
months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];
if(min.length == 1){
min = '0' + min;
}
obj.innerHTML = hours + ':' + min;
}
<div id="time1">October 25, 2018 18:00 GMT+0300 (CDT)</div>
<div id="time2">October 25, 2018 18:00 GMT+0300 (CDT)</div>
<div id="time3">October 25, 2018 18:00 GMT+0300 (CDT)</div>
请告诉我这是否有帮助!谢谢!
