<h1 align="center">Find and Replace using split() and join()</h1>

<div style="width:400">
<p>
You have probably seen other find and replace scripts that use Range or
TextRange objects to find and replace text, or indexOf() and substring()
to manipulate the text, but I have found a third way to do that, which is
via the split() and join() methods.
</p>

<p>
Normally, the split() and join() methods are used to combine arrays into 
strings, to be stored in cookies. But they can also be used for a find and 
replace script, such as this one.
</p>

<p>
The split() method takes a peice of text and/or HTML, and makes each peice 
of text before and after each occurance of the text into an array item.

<xmp>
Example:
var text = "Congress shall make no law respecting an establishment of religion";
text = text.split("a")

This would equal:
var text = new Array();
text[0]="Congress shall make no l";
text[1]="w respecting ";
text[2]="n est";
text[3]="blishment of religion";

all of the "a"s have been removed 
</xmp>
</p>

<p>
The join() method does the opposite, it recontructs the array into a string
<xmp>
Example:
text = text.join("a")

This would equal:
var text = "Congress shall make no law respecting an establishment of religion";

However, you can use a different character for join()

Example:
text = text.join("117")

This would equal:
var text = "Congress shall make no l117w respecting 117n est117blishment of religion";
</xmp>
</p>

<p>
That's how this script works. Try it using the form below.
</p>
<p align="right">
<form>
Find:<input id="find" value="law"><br />
Replace with:<input id="replaceWith" value="legislation"><br />
Number of items:<input id="number"><br />

<button id="button" onclick="FindReplace('find','replaceWith')">Go!</button>
</form>
</p>
