View Full Version : I need help with building a computer business website

08-25-2002, 08:19 PM
I need help with building a computer website to where I can have people customize and PC and it will tell their price (either in real-time or by clicking a button to update). Now I know all it takes is some java script in the head or wherever on the page, but since I am a noob at javascript, I have no clue.

If anybody could help me as in actually building a site, or just giving my tutorial url's or emails; that would be greatly appreciated.

try the following links:

Webmonkey (http://www.webmonkey.com)

HtmlGoodies (http://www.htmlgoodies.com)

w3schools (http://www.w3schools.com)

They should give you the basics. They won't give you ready made scripts, but should guide you on some stuff.

I know HTML, it is just that i want to define a variable and then total the value of all variables but I dont know how to do it, here is an example:

function calculateTotal() {
var Motherboard=document.Configuration(name of the form).Motherboard(name of the box).value
var total= (all vars)


It has an error...and I dont know the correct operators to use when trying to get the value.

Remember i am trying to get specific values of choices in drop down boxes.

It is actually quite simple. Make an array for each select box.

var CPUvalue = new Array(3)
CPUvalue[0] = 75
CPUvalue[1] = 100
CPUvalue[2] = 125

varMOBvalue = new Array(3)
MOBvalue[0] = 125
MOBvalue[1] = 150
MOBvalue[0] = 135

0 corresponds to the first entry in the select box, 1 to the second, etc.
And then you would need a function not unsimilar to this:

function computeTotal(form)
CPU = CPUvalue[form.CPU.selectedIndex]
MOB = MOBvalue[form.Mainboard.selectedIndex]

total = (CPU + MOB)

form.total.value = total

<form name="form">
<select size="1" name="CPU" onChange="computeTotal(this.form)>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>

<select size="1" name="Mainboard" onChange="computeTotal(this.form)>
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>

<input type="text" name="total" size="10">

Of course if you want to get fancy, you could always just put total in a document.write

If you have any other questions regarding this, or would like to see a full scale example, feel free to email me @ mojuba@comcast.net
Oh I almost forgot, if you want the script to total up on page load just add onload="computeTotal(this.form)" to the BODY tag.
