You can certainly format the date yourself..
你当然可以自己格式化日期..
var mydate = new Date(form.startDate.value);
var month = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"][mydate.getMonth()];
var str = month + ' ' + mydate.getFullYear();
You can also use an external library, such as DateJS.
您还可以使用外部库，例如DateJS。
Here's a DateJS example:
这是一个 DateJS 示例：
<script src="http://www.datejs.com/build/date.js" type="text/javascript"></script>
<script>
var mydate = new Date(form.startDate.value);
var str = mydate.toString("MMMM yyyy");
window.alert(str);
</script>

var month = mydate.getMonth(); // month (in integer 0-11)
var year = mydate.getFullYear(); // year
Then all you would need to have is an array of months:
那么你所需要的只是一系列月份：
var months = ['Jan', 'Feb', 'Mar', ...];
And then to show it:
然后显示它：
alert(months[month] + " " + year);

Use your mydate object and call getMonth() and getFullYear()
使用您的 mydate 对象并调用 getMonth() 和 getFullYear()
