Try this; bear in mind that JavaScript months are 0-indexed, whilst days are 1-indexed.
尝试这个; 请记住，JavaScript 月份是 0 索引的，而天是 1 索引的。
var date = new Date('2010-10-11T00:00:00+05:30');
alert(((date.getMonth() > 8) ? (date.getMonth() + 1) : ('0' + (date.getMonth() + 1))) + '/' + ((date.getDate() > 9) ? date.getDate() : ('0' + date.getDate())) + '/' + date.getFullYear());回答by Ore4444
All other answers don't quite solve the issue. They print the date formatted as mm/dd/yyyy but the question was regarding MM/dd/yyyy. Notice the subtle difference? MM indicates that a leading zero must pad the month if the month is a single digit, thus having it always be a double digit number.
所有其他答案都不能完全解决问题。他们打印格式为 mm/dd/yyyy 的日期，但问题是关于 MM/dd/yyyy。注意到细微的差别了吗？MM 表示如果月份是一位数，则必须用前导零填充月份，因此它始终是两位数。
i.e. whereas mm/dd would be 3/31, MM/dd would be 03/31.
即 mm/dd 为 3/31，MM/dd 为 03/31。
I've created a simple function to achieve this. Notice that the same padding is applied not only to the month but also to the day of the month, which in fact makes this MM/DD/yyyy:
我创建了一个简单的函数来实现这一点。请注意，相同的填充不仅适用于月份，还适用于月份中的第几天，这实际上使这个 MM/DD/yyyy：
function getFormattedDate(date) {
var year = date.getFullYear();
var month = (1 + date.getMonth()).toString();
month = month.length > 1 ? month : '0' + month;
var day = date.getDate().toString();
day = day.length > 1 ? day : '0' + day;
return month + '/' + day + '/' + year;
}Update for ES2017 using String.padStart(), supported by all major browsers except IE.
使用 String.padStart() 更新 ES2017，除 IE 外的所有主要浏览器都支持。
function getFormattedDate(date) {
let year = date.getFullYear();
let month = (1 + date.getMonth()).toString().padStart(2, '0');
let day = date.getDate().toString().padStart(2, '0');
return month + '/' + day + '/' + year;

Pass your string into the DateObject:
将您的字符串传递到DateObject 中：
var d = new Date("2010-10-30T00:00:00+05:30");
from here you can extract the desired using the following methods:
从这里您可以使用以下方法提取所需的内容：
d.getMonth()+1 // 10
d.getDate() // 30
d.getFullYear() // 2010
Note that getMonth()returns the month number zerobased (0-11)therefore a +1is needed.
请注意，getMonth()返回月份数零基础（0-11）因此，一个+1是需要的。

Another way, using .slice()and .split()
另一种方式，使用.slice()和.split()
var d = "2010-10-30T00:00:00+05:30".slice(0, 10).split('-');
d[1] +'/'+ d[2] +'/'+ d[0]; // 10/30/2010
