Using Javascript to input time in HTML5 time field
提问by Envious
I'm trying to create a function in JS that will fill in the html5 <input type=time>with a format like this hh:mm:ss.
我正在尝试在 JS 中创建一个函数，它将<input type=time>用这样的格式填充 html5 hh:mm:ss。
function timeChange(){
var d = new Date();
d.getHours();
d.getMinutes();
d.getSeconds();
var hours = d.getHours();
var minutes = d.getMinutes();
var seconds = d.getSeconds();
document.getElementById("time_in").value = (....);
}
I'm not sure how to code the .value for this. I've tried using .value = (hours":"minutes":"seconds);but that just gives me a compile error.
我不确定如何为此编码 .value。我试过使用，.value = (hours":"minutes":"seconds);但这只会给我一个编译错误。
Anyone got ideas? I just need it in hh:mm:ss.
有人有想法吗？我只需要它在 hh:mm:ss 中。

hours":"minutes":"secondsisn't concatenating the string, you need +s: hours+":"+minutes+":"+seconds
hours":"minutes":"seconds不是连接字符串，你需要+s：hours+":"+minutes+":"+seconds

var d = new Date();
// Need to create UTC time of which fields are same as local time.
d.setUTCHours(d.getHours(), d.getMinutes(), d.getSeconds(), 0);
document.getElementById("time_in").valueAsDate = d;
回答by Ryan
document.getElementById('time_in').value = hours + ":" + minutes + ":" + seconds;
Otherwise you're not creating one concatenated string.
否则，您不会创建一个连接字符串。

The simplest way would be to grab the time string from the Date object:
最简单的方法是从 Date 对象中获取时间字符串：
var time = (new Date()).toTimeString().split(' ')[0];
var time = (new Date()).toTimeString().split(' ')[0];
The split allows us to remove the timezone portion of the string.
拆分允许我们删除字符串的时区部分。
