if not postback javascript equivalent

Question

In c# we have IsPostBack that we use to validate if is or isn't a postback.

if (!IsPostBack)
{
    // Validate initially to force asterisks
    // to appear before the first roundtrip.
    Validate();
}

There is a javascript/jQuery equivalent?

Note that

I don't wanna a solution using any other language than javascript (not excluding html, since it is not a programming language). Those questions below show how to do it using c#, I don't wanna that!. I want a solution in javascript (or jQuery) ONLY.

No, there is no direct equivalent. You'd have to track the state of the application using JavaScript. One popular way of doing that is hashbang urls. Ex:

http://domain.com/#some-state or http://domain.com/#/some-state

window.location.hash exposes the hashbang url and there are frameworks like AngularJS that make working with hashbang urls to control state and what view is displayed very easy.
