JavaScript Objects: More on String Methods - The LastIndexOf() Method
(Page 6 of 6 )

This is very similar to our previous method and to be honest, every time I have used it, it brings back the same result. It is supposed to result in the last position of your string value, but it always returns the starting position.

The Link() Method

You use the Link() method to create links in JavaScript.




<script type="text/javascript">

var website="Developer Shed!"

document.write("<p>Here is a link: " + website.link("http://www.devshed.com") + "</p>")




That would result in the following:

  Here is a link:   Developer Shed!  

The Match() Method

Similar to the IndexOf() method, the Match() method allows you to search a string of text for a specified string. However, instead of returning the numeric position for your result, it returns the actual string itself, or null if it does not find the value. Here it is in code:



<script type="text/javascript">

var love="I love Gorillas!"

document.write(love.match("I") + "<br />")

document.write(love.match("love") + "<br />")

document.write(love.match("to eat") + "<br />")





The mind shattering results:


And that wraps it up for this tutorial my apelike friends. Be sure to join me in our next Object packed tutorial as I (hopefully) finish off our discussion of JavaScript String Objects.
