Javascript Sorting - Example 5

Intermediate sorting

This page demostrates the use of a comparison function with the Javascript sort method. The function will perform a reverse alphabetic sort.

For more information return to the article "Sort Your Data with Javascript".

Example code

// Create a test array

var wordList = new Array( "tiger", "cat", "dog");

// Create a comparison function

function reverseAlphabeticTest(a, b) {

   if (a < b) return 1;

   if (a > b) return -1;

   return 0;

}

// Sort all elements of the array using a comparison function

wordList.sort(reverseAlphabeticTest);

This table contains the original array and the sorted array.
