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.
