Or do you want to get a new array so you can do other things with it? I'll assume the latter, since it's more generally useful. Assuming the 'book' array is in order, you just need to write a loop that finds the first element you want, and then a loop that copies everything into a new array until you find the first element you don't want. [code] firstChapter = 4; lastChapter = 6; line = 0; // skip the lines we don't want for ( ; line < book.length; line++ ) { if ( book[line][0] == firstChapter ) break; } // grab the lines we do want result = new Array(); for ( ; line < book.length; line++ ) { if ( book[line][0] > lastChapter ) break; // stop when we see something we don't want result[result.length] = book[line]; // append this line to the end of the 'result' array // if all you want is word counts, you could just tally the word count here instead. } return result; [/code] [url=http://www.slimeland.com/] [img]http://www.slimeland.com/misc/ozonemetalslimesig.gif[/img] [/url] [small](Edited by [url=http://www.ozoneasylum.com/user/5]Slime[/url] on 12-08-2009 11:03)[/small] Loading...
