如何在JavaScript中获得当前时间并在时间选择器中使用它?
我尝试了var x = Date()，得到:
2012年5月15日星期二05:45:40 GMT-0500
但我只需要现在的时间，比如05:45
我怎么把它赋值给变量呢?

看看这些Date方法…

var today = new Date(); //gets current date and time
var hour = today.getHours();
var minute = today.getMinutes();
var second = today.getSeconds();
Date.toLocaleTimeString()选项
Date.toLocaleTimeString()函数可以接收一个选项参数来格式化输出
以下是一些可用的选项
new Date().toLocaleTimeString([], { timeStyle: "full" }) // 4:43:58 AM Pacific Standard Time
new Date().toLocaleTimeString([], { timeStyle: "long" }) // 4:43:58 AM PST
new Date().toLocaleTimeString([], { timeStyle: "medium" }) // 4:43:58 AM
new Date().toLocaleTimeString([], { timeStyle: "short" }) // 4:43 AM
或者你可以用这些值指定小时、分钟和秒的表示形式:
“数字”(例如，1) “2位数”(例如，01)
new Date().toLocaleTimeString([], { hour: '2-digit', minute: "2-digit" })
// 04:43 AM
或者使用hour12: true或false设置12小时时间
更多细节请看 Date.toLocaleTimeString()参数 Intl.DateTimeFormat()选项
var d = new Date("2011-04-20T09:30:51.01");
d.getHours(); // => 9
d.getMinutes(); // => 30
d.getSeconds(); // => 51
or
var d = new Date(); // for now
d.getHours(); // => 9
d.getMinutes(); // => 30
d.getSeconds(); // => 51
var hours = date.getHours();
var minutes = date.getMinutes();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0'+minutes : minutes;
var strTime = hours + ':' + minutes + ' ' + ampm;
console.log(strTime);
$scope.time = strTime;
date.setDate(date.getDate()+1);
month = '' + (date.getMonth() + 1),
day = '' + date.getDate(1),
year = date.getFullYear();
if (month.length < 2) month = '0' + month;
if (day.length < 2) day = '0' + day;
var tomorrow = [year, month, day].join('-');
$scope.tomorrow = tomorrow;
