Use of push () in jquery (array add Element)

Push definition and usage

The push () method adds one or more elements to the end of the array and returns the new length.

Grammar

Arrayobject.push (Newelement1,newelement2,...., newelementx)

Parameter description
Newelement1 required. The first element to add to the array.
Newelement2 is optional. The second element to add to the array.
Newelementx is optional. You can add multiple elements.

return value

Adds the specified value to the new length after the array.

Description

The push () method adds its parameter order to the tail of the arrayobject. It modifies the arrayobject directly, rather than creating a new array. The push () method and the Pop () method use the advanced post-stack functionality provided by the array.

Hints and Notes

Note: This method will change the length of the array.
Tip: To add one or more elements to the beginning of an array, use the Unshift () method.

Instance

In this example, we will create an array and change its length by adding an element:

var arr = new Array (3);
Arr[0] = "George";
ARR[1] = "John";
ARR[2] = "Thomas";
document.write (arr + "") document.write (Arr.push ("James") + "") document.write (arr);

Output:
George,john,thomas
4
George,john,thomas,james

One usage on the Web:

$ (function () {
var buf = [www.nuoya66.com];
Buf.push (' <script async src= ' http://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js ' ></script > ');
Buf.push (' <ins class= ' Adsbygoogle "style=" display:inline-block;width:728px;height:90px "data-ad-client=" ca-pub-88888888 "data-ad-slot=" 8305246055 "></ins>");
Buf.push (' <script> (adsbygoogle = Window.adsbygoogle | | []). push ({});</script> ');
$ ('. Footer-banner '). HTML (Buf.join ("));
