Javascript: Price Calculator in JavaScript, perimeter length, price calculator. Expert: Anthony Levensalor - 1/3/2007 QuestionHi!
I'm trying to create a price calculator for custom-made picture frames to post on my website. I want users to be able to type in the length and the width into a table and then it displays the estimated price. There are three different frame thicknesses; 1.5" Narrow Barnwood, 2" Rustic Barnwood, and 3" Thick Barnwood, so a drop-down menu or something that would let users choose the design would be awesome. I came up with an equation that will do the trick. First we find the square area of the frame by multiplying the perimeter (length+length+width+width) by the thickness of the frame (which will either be 1.5" 2" or 3"). So it is as follows: [2*(l+w) *Thickness] * 0.27 if its 1" Thick, 0.23 if its 2" and 0.18 if its 3" thick. I have no clue whatsoever when it comes to javascript, how to code this. Here's what I got so far: document.getElementById('calc'... = total + 5; } </script> Help with javascript price calculator!

Lets get straight to it, by creating a PHP script that gets the file names of all images inside the directory the script is placed in, and return them as a JavaScript array: This script will grab the file names of every image in a directory (based on its extension) and output them as JavaScript array elements: where "dog.gif", "cat.gif" etc are the file names of the images inside the directory.
