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

Push definitions and usage

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

Grammar

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

Parameter description
Newelement1 required. The first element to add to the array.
Newelement2 Optional. The second element to add to the array.
Newelementx Optional. Multiple elements can be added.

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. Instead of creating a new array, it directly modifies the arrayobject. The push () method and the Pop () method use the advanced stack functionality provided by the array.

Tips and comments

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

Instance

In this case, we'll create an array and change its length by adding an element:

Copy Code code as follows:

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

A usage on the Web:

Copy Code code as follows:

$ (function () {
var buf = [];
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 ('));

Note: You need to load the jquery.js before you use it
