If you're running with jQuery you can use the datepicker UI library's parseDate function to convert your string to a date:
如果您使用 jQuery，您可以使用 datepicker UI 库的 parseDate 函数将您的字符串转换为日期：
var d = $.datepicker.parseDate("DD, MM dd, yy", "Sunday, February 28, 2010");
and then follow it up with the formatDate method to get it to the string format you want
然后用 formatDate 方法跟进它以得到你想要的字符串格式
var datestrInNewFormat = $.datepicker.formatDate( "mm/dd/yy", d);
If you're not running with jQuery of course its probably not the best plan given you'd need jQuery core as well as the datepicker UI module... best to go with the suggestion from Segfault above to use date.js.
如果你没有使用 jQuery，当然它可能不是最好的计划，因为你需要 jQuery 核心以及 datepicker UI 模块......最好按照上面 Segfault 的建议使用 date.js。

var stringDate = "Sunday, February 28, 2010";
var months = ["January", "February", "March"]; // You add the rest :-)
var m = /(\w+) (\d+), (\d+)/.exec(stringDate);
var date = new Date(+m[3], months.indexOf(m[1]), +m[2]);
The indexOfmethod on arrays is only supported on newer browsers (i.e. not IE). You'll need to do the searching yourself or use one of the many libraries that provide the same functionality.
indexOf数组上的方法仅在较新的浏览器（即不支持 IE）上受支持。您需要自己进行搜索或使用提供相同功能的众多库之一。
Also the code is lacking any error checking which should be added. (String not matching the regular expression, non existent months, etc.)
此外，该代码缺少应添加的任何错误检查。（字符串不匹配正则表达式，不存在的月份等）

If you only need it once, it's overkill to load a plugin.
如果您只需要它一次，那么加载插件就太过分了。
For a date "dd/mm/yyyy", this works for me:
对于日期“dd/mm/yyyy”，这对我有用：
new Date(d.date.substring(6, 10),d.date.substring(3, 5)-1,d.date.substring(0, 2));
Just invert month and day for mm/dd/yyyy, the syntax is
new Date(y,m,d)
只需反转 mm/dd/yyyy 的月和日，语法是
new Date(y,m,d)

Use moment js for any date operation.
使用 moment js 进行任何日期操作。
console.log(moment("Sunday, February 28, 2010").format('MM/DD/YYYY'));<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>
