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 this is a third way to do that, which is via the split() and join() methods.

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><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><P>That's how this script works.
