I have the following code that I wrote myself (except for the function isNumberKey). However, I don't know how to actually add the numbers together. My plan is to store the value entered in the forms as a variable, then manipulate the variables to get my final number. The final number would be stored in variable named Total and would be displayed after Total: at the bottom of my page.
<HTML>
I am using this code to validate a form to check that only numbers have been entered but when I enter alphabets the javascript raises an error but still submits the form.
<script type='text/javascript'>
function isNumeric(elem, helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}}
</script>
<form>
Numbers Only: <input type='text' id='numbers' action= "desktop.html"/>
<input type='button'
onclick="isNumeric(document.getElementById('numbers'), 'Numbers Only Please')"
value='Check Field' />
</form>
I am making a form using HTML and java where you enter a number and it uses an equation then spits out another number. My problem is I want to split the number you put into the form and add it up. Example You enter"457829"Press "convert"And the first step I want it to do is"4+5+7+8+2+9=sumA"Then"sumA/8"So far I can only do the sumA/8 if I manually add up the numbers then place the sum in the form, here's the code:
Code:
{
var a = parsefloat(form.NumA.value, 10);
[code]....
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.

I am constructing an HTML questionnaire and one of the questions
requires people to rate some choices from 1 to 5, where 1 is their
favourite and 5 is their least favourite:
Car
Bus
Taxi cab
Train
Airplane
Each choice has an INPUT TYPE=TEXT tag to contain the response. I
also have a function that is called ONCHANGE in order to check that a
number is entered between 1 and 5:
function CheckNos(obj) {
if(obj.value.match(/[^d]/) || obj.value<1 || obj.value>5)
{alert("Please enter a number between 1 and 5");obj.value="";return
false}
}
This works fine, but ideally I would like a function that could check
ONCHANGE that someone has not filled in the same number twice, for
example answered "1" for all of them. They are only allowed to use
each rating number once, so rating their choice 1 to 5.
Can anyone suggest a short function that could accomplish this easily?
Could I use some kind of array with 5 elements and allocate a flag
value once that number had been chosen, then check that the value had
been set?
I'm trying to make sure that when a user enters information into my textbox, that when the textbox loses focus then it checks to make sure that they entered numbers and not text or other characters. Numbers only....Any suggestions?

Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890
So that it appears as: (123) 456-7890 with a blank space after the ")"
(2)If that's simple, is there a way to error-check it so that only numbers can be entered into the phone number input field?
I am inexperienced in JavaScript. I have an html page with several numeric input fields which are an array. At the bottom of the screen is a running total of the numbers entered.
The html is like:
<INPUT TYPE=TEXT NAME='array[0]' onchange='addup()'>
<INPUT TYPE=TEXT NAME='array[1]' onchange='addup()'>

I need to add 18 months to a date entered on a form and show the results to the user without the time. so a date like 1/1/2000 is entered and the results should be 06/30/2001. I am parsing the string and adding 18 months of milliseconds to the date. While I have gotten this to work, it is not correct because each month has a different # of days.
add 18 months to a date entered by a user?
Code:
var str = document.form1.startdate.value;
var d1 = Date.parse(document.form1.startdate.value);
var d7 = d1+86400000*30*18;

I'm trying to do a homework problem that involves using cookies to add numbers.
Here is what I've done so far:
The code is simply supposed to prompt the user asking how many numbers he/she would like to add. Then it is supposed to have additional prompts asking for each individual number. As the numbers are being inputted, it is supposed to keep a running sum via cookies and then output the total at the end.
The problem that I'm having is that I don't think the cookies are even being created which is weird because the createCookie(), printCookie(), and overWriteCookie() methods are copied directly from the textbook.
Does anyone know what i'm doing wrong here. Instead of adding my numbers together its putting them next to each other?

I'm wondering how I can add numbers in real time using javascript.
example,
say I enter a number in a text field,
<input type="text" name="qty" value="2">
<input type="text" name="cost" value="5">
how would I then be able to get the total in another test field, like:
<input type="text" name="total" value="10">
I am re-developing my website and want to use some Ajax/jQuery in it (so I am learning as I go) and I am not sure if this is possible so that is my first question:I have a registration form and I would like to know if after the person registering has completed their first and surname and the 2 sections of their postcode if I can use jQuery to run a PHP script to see if they are already registered before waiting for the form to be submitted and running a script then.I am thinking onkeyup (or similar) after the last field is completed but I don't know how that would work needing to also use 3 other field values.If this is possible, can anyone give me any ideas of examples that do this or how I can go about passing all the variables and running the scripts at the correct time.

I have a JavaScript application that needs to preserve double quote marks and apostrophes (" and ') that are entered into form fields by the user. The form data is passed through several screens using hidden fields.
Right now, apostrophes work because I have the input fields coded as value="". I have not found a way for JavaScript to retrieve the field's value if double quotes are entered by the user. If I change the parameter to value='' (single quotes) then the apostrophes probably won't work.
Is there a straightforward way for JavaScript to retrieve the field value containing quotes, so that I can manipulate it into a different string that can be easily passed between HTML pages?
Basically i need help with input fields that when clicked the text (value) disappears but if the user has not entered anything in it would revert back to what was originally there.I have managed to get the value inside to disappear once clicked without the use of javascript but would love someone to point me in the right direction of how to revert the original value back if nothing was entered in if the user did click inside as the field continues to be blank.
