Javascript Array

By

Javascript Array

An array is a variable that can store many variables within it. Many programmers have seen arrays in other languages, and they aren't that different in JavaScript.

Creating a JavaScript Array

Creating an array is slightly different from creating a normal variable. Because JavaScript has variables and properties associated with arrays, you have to use a special function to create a new array. This example shows how you would create a simple array, store values to it, and access these values.
JavaScript Code:

<script type="text/javascript">
<!--
var myArray = new Array();

myArray[0] = "Football";
myArray[1] = "Baseball";
myArray[2] = "Cricket";

document.write(myArray[0] + myArray[1] + myArray[2]);
//-->
</script>

Output:
FootballBaseballCricket

JavaScript Array Sorting

Imagine that you wanted to sort an array alphabetically before you wrote the array to the browser. Well, this code has already been written and can be accessed by using the Array's sort method.
JavaScript Code:

<script type="text/javascript">
<!--
var myArray2= new Array();

myArray2[0] = "Football";
myArray2[1] = "Baseball";
myArray2[2] = "Cricket";

myArray2.sort();

document.write(myArray2[0] + myArray2[1] + myArray2[2]);
//-->
</script>

Display:

Accessible Forms

By
Forms aren't the easiest of things to use for people with disabilities. Navigating around a page with written content is one thing, hopping between form fields and inputting information is another. Because of this, it is a good idea to add a number of elements to the form. Labels Each form field should have its own label. The label tag sorts this out, with a for attribute that associates it to a form element:
