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 1

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.

Answer 2

you can remove all item in myArray using array length, it's common pattern.

try this

var myArray = [1, 2, 3];     myArray.length = 0; // remove all item
