JavaScript Objects: Finishing Strings - The Slice() Method
(Page 4 of 6 )
The Slice() method is used when you want to divide up a pizza into separate portions. It is also used when you wish to extract or slice a part of a string and return it to a new string.
<html>
<body>
<script type="text/javascript">
var castle="Castle Greyskull!"
document.write(castle.slice(6))
document.write("<br />")
</script>
</body>
</html>
This code finds the text in the sixth string and returns it, resulting in:
Greyskull!
If we wanted to grab more than one value, we do it like this:
<html>
<body>
<script type="text/javascript">
var castle="Castle Greyskull!"
document.write(castle.slice(6))
document.write("<br />")
document.write(castle.slice(0,17))
document.write("<br />")
document.write(castle.slice(0,15))
</script>
</body>
</html>
This results in the following manner:
Greyskull!
Castle Greyskull!
Castle Greyskul
You will note that in the last criteria, I used the value 15, and hence we only got part of the word Greyskull, or Greyskul.
