如何拆分JavaScript数组？

Question

In python, I can remove the first item from array xs like so:

xs = xs[1:]

How could I do that with the following javascript array?

var data = {{data}}

Answer 1

The JavaScript splice function, not an specific of jQuery.

 var fruit = ["Banana", "Orange", "Apple", "Mango", "Kiwi"]; var removed = fruit.splice(0, 1); console.log(removed); console.log(fruit); 

The result is ["Orange", "Apple", "Mango", "Kiwi"]

Answer 2

If you want to get the first value out of an array and remove it from the array, you can use Array#shift ( MDN | spec ):

 var a = [1, 2, 3, 4]; // An array var first = a.shift(); // Remove and return the first entry console.log(first); // Show the value we got console.log(a); // Show the updated state of the array
