javascript - How to remove elements from Array?

How to remove all items from jQuery array?

I have array var myArray = [];, I want to clear all items in this array on every post back.

Answer

Simplest thing to do is just

myArray = [];

again.

edit — as pointed out in the comments, and in answers to other questions, another "simplest thing" is

myArray.length = 0;

and that has the advantage of retaining the same array object.
