As a corollary to this question, if you created an object in javascript using the syntax new (Date) how would you pass in any constructor args/params?

In other words is there an equivalent of new Date(2000) or is that just how you would do it?

有帮助吗?

解决方案

The parens return the result of the contained expression, so this will work:

new (Date)(2000);

This is the same as:

new Date(2000);

其他提示

Have you tried: new (Date)(2000)? Not exactly pretty code...
