Java date format to JavaScript date format

Question

I would like to be able to convert a Java date format string, e.g. dd/MM/yyyy (07/06/2009) to a JavaScript date format string, e.g. dd/mm/yy (07/06/2009).

Answer 1

If you just need to pass a date from Java to JavaScript, the best way to do it, I think, would be to convert the Java date to milliseconds using date.getTime(), create a JavaScript date initialized with this milliseconds value with new Date(milliseconds)and then format the date with the means of the JavaScript Date object, like: date.toLocaleString().

Answer 2

This works fine for me:

<%
Date date = Calendar.getInstance().getTime();
%>

<script>
var d = new Date(<%=date.getTime()%>);
alert(d);
</script>

Answer 3

I suggest you the MomentJS with this Plugin that allow you to convert a Java pattern to a JS pattern (MomentJS)

Answer 4

If you just want to format dates my date extensions will do that well - it also parses data formats and does a lot of date math/compares as well:

DP_DateExtensions Library

Not sure if it'll help, but I've found it invaluable in several projects.
