Question

How can I convert that date format /Date(1302589032000+0400)/ to JS Date object?

Answer 1

Remove the text first:

var src = "/Date(1302589032000+0400)/";

//Remove all non-numeric (except the plus)
src = src.replace(/[^0-9 +]/g, ''); 

//Create date
var myDate = new Date(parseInt(src));
