This is an assignment I have for a course I am taking. The objective is to validate the zipcode of a form to ensure that it only contains numbers. I cannot get this to work. The teacher wants us to use the for loop to do this, otherwise I would use a different function.
Code:
<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8">
<head> .....
i using for my contact form
[URL]
The above code was copied from a Youtube tutorial about JavaScript.
I would like to ask, what additional code should be added in the existing code in order to validate the numbers only and an email format before the form to be submitted?

I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.

have a form with three fields for home phone, work phone & mobile phone.I've got jquery to validate that the numbers entered are the right format, i.e. using the following with custom methods for the phoneUK etc.The thing is I only need one of these numbers. I have been trying *all day* to try and get this to work but no joy. I know I need to group them somehow but can't figure it out.I want it so I get a single message if all fields are left empty and then if a field does have an entry then it's validated to ensure its a number.

I need a regular expression to validate a string which consists of numbers, seprated by a period. For example: 123.456.7890.123 or
543245634.564362454.543543523.43532543
Basically, its a set of any amount of numbers, seperated by a period, ocurring any number of times. Now this is my first time dealving into regular expressions, and after reading some tutorials i came up with this:
/+((+d).)/
Would this evaluate correctly?

I have to code an errorPlacement for my form checkboxes. The form works good with the default behavior; but I don't get how to code a special errorPlacement for the checkboxes. I used the Milk form demo. My working form (less the checkboxes) is at [URL] and the non-working one is [URL]. I know this must be really basic but I really new at this (I'm just a designer doing his best!)

How to validate more than one field in JavaScript

Another quick question. I have the script to add each field up I need, but if the ending 0 after a decimal is present it doesnt show. How do I keep the leading zero and how do I keep just 2 digits after the decimal?
For example:
1 + 1.50 = 2.50
But javascript displays it as 2.5
Now sometimes when I do math I get:
2.3454545
In this case I just want 2.34. So if there is a ending zero I want to keep it, and if there is more than 2 numbers after the decimal I want to cut the rest off and leave the 2 there.
I have an HTML form, that's part of a child window,and has two random numbers in it. How can i have it so when user inputs the sum in an empty box in the form, and clicks 'submit' the result is displayed in the main window? Also, it needs to check if answer is correct or wrong and show that in the main window at the same time.
