function getCurrentTime(){
    var date = new Date();
    var hh = date.getHours();
    var mm = date.getMinutes();

    hh = hh < 10 ? '0'+hh : hh; 
    mm = mm < 10 ? '0'+mm : mm;

    curr_time = hh+':'+mm;
    return curr_time;
}

赋值给变量并显示。

time = new Date();

var hh = time.getHours();
var mm = time.getMinutes();
var ss = time.getSeconds() 

document.getElementById("time").value = hh + ":" + mm + ":" + ss;

看看这些Date方法…

getTime() {
      let today = new Date();
      let h = today.getHours();
      let m = today.getMinutes();
      let s = today.getSeconds();
      h = h < 10 ? "0" + h : h;
      m = m < 10 ? "0" + m : m;
      s = s < 10 ? "0" + s : s;
      let time = h + ":" + m + ":" + s;
      return time;
    },

在ES6中一个简单的方法是这样做的，在你要求的格式(hh:mm):

const goodTime = ' ${new Date().getHours()}:${new Date().getMinutes()} '; console.log(因着);

(显然，控制台日志记录不是解决方案的一部分)

function getCurrentTime(){
    var date = new Date();
    var hh = date.getHours();
    var mm = date.getMinutes();

    hh = hh < 10 ? '0'+hh : hh; 
    mm = mm < 10 ? '0'+mm : mm;

    curr_time = hh+':'+mm;
    return curr_time;
}
