convert Java datestring to javascript date
提问by orshachar
When I send a date through JSON from Java to Javascript, it sends something like this:
当我通过 JSON 从 Java 向 Javascript 发送日期时，它会发送如下内容：
var ds = "11:07:47 13/01/2011";
Javascript fails to parse this string into date
Javascript 无法将此字符串解析为日期
var d = new Date(ds);
Any ideas?
有任何想法吗？

You need some JS that parse the String and return the year, month, day, minute,hour, second in strings:
您需要一些 JS 来解析字符串并返回字符串中的年、月、日、分钟、小时、秒：
var hour = ds.split(":")[0],
minute = ds.split(":")[1],
last_part = ds.split(":")[2],
second = second_part.split(" ")[0],
last_part2 = second_part.split(" ")[1],
day = last_part2.split("/")[0],
month = last_part2.split("/")[1],
year = last_part2.split("/")[2];
and then instantiate the Date constructor:
然后实例化 Date 构造函数：
var d = new Date ( year, month, day, hour, minute, second );

To be on the safe side you should get the time in milliseconds in Java and send that through JSON to JavaScript. There you can use
为了安全起见，您应该在 Java 中获取以毫秒为单位的时间，并通过 JSON 将其发送到 JavaScript。在那里你可以使用
var d = new Date();
d.setTime(valueInMilliseconds);

There are a number of ways you can call the Dateconstructor.
From the reference at http://www.w3schools.com/js/js_obj_date.asp:
您可以通过多种方式调用Date构造函数。
来自http://www.w3schools.com/js/js_obj_date.asp的参考：
new Date() // current date and time
new Date(milliseconds) //milliseconds since 1970/01/01
new Date(dateString)
new Date(year, month, day, hours, minutes, seconds, milliseconds)

function stringToDate(_date,_format,_delimiter)
{
var formatLowerCase=_format.toLowerCase();
var formatItems=formatLowerCase.split(_delimiter);
var dateItems=_date.split(_delimiter);
var monthIndex=formatItems.indexOf("mm");
var dayIndex=formatItems.indexOf("dd");
var yearIndex=formatItems.indexOf("yyyy");
var month=parseInt(dateItems[monthIndex]);
month-=1;
var formatedDate = new Date(dateItems[yearIndex],month,dateItems[dayIndex]);
return formatedDate;
}
stringToDate("17/9/2014","dd/MM/yyyy","/");
stringToDate("9/17/2014","mm/dd/yyyy","/")
stringToDate("9-17-2014","mm-dd-yyyy","-")
