How to create array and add element |
We can create arrays in JavaScript in different ways. Handling of arrays using JavaScript is required in many applications. If we are processing a form then elements of the form can be managed as part of an array. We will learn some different points on use of arrays and before that we will learn some basics of JavaScript array.
How to create arrays in JavaScript?
We can declare an array like this
var scripts = new Array();
We can add elements to this array like this
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
Now our array scrips has 4 elements inside it and we can print or access them by using their index number. Note that index number starts from 0. To get the third element of the array we have to use the index number 2 . Here is the way to get the third element of an array.
document.write(scripts[2]);
We also can create an array like this
var no_array = new Array(21, 22, 23, 24, 25);
