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.

---

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.

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

There is no such thing as a jQuery array, that's just a javascript array. When a page posts back, it re-renders and all of the javascript is re-run, you don't need to clear the contents of the array.

if, during execution of the page, you wanted to clear a javascript array, just re-initialize it as a new, blank array:

myArray = []; // no var, we are just initializing not declaring
