# Splitting Then Adding A Number Entered Into A Form?

Aug 7, 2010

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);

## Adding Numbers That Have Been Entered In A Form

Aug 25, 2011

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.

## Adding Random Number To HTML Form?

May 29, 2009

I have a pretty basic HTML form, it doesn't go to a database or anything, it just gets emailed directly to the owner of the website with their customer query.However, the owner has now asked that each query be assigned a random reference number of no more than 16 digits which must also be visible to the customer.I presume this will be relatively easy but I'm a complete beginner with Javascript which I assumed would be necessary for generating the number. I've sort of figured out how to generate the number but I can't figure out how to get that number into a read-only field on the form so that it will be both visible to the client and sent with the rest of the data on the form to the owner.I've had a number of attempts but this is what I'm trying at the moment:

## Adding Months To Entered Date?

Apr 18, 2011

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;

## Calculator Calculation - 1st Number Entered Displaying It And Storing It In The Variable "memory"

Feb 13, 2011

This is calculator program that I have gotten stuck on. Here is where I think I am at:

The program is now taking the 1st number entered displaying it and storing it in the variable "memory".

Operation (+,-,*,/) is added to the memory in function action1() but then when the second number is entered it replaces memory with the second number. How can I get the variable memory to the whole string of 1st number,action, 2nd number?

Also once I do get that working correctly:

Wouldn't eval(document.calculator.display.value= memory) in my HTML for the "=" give me the calculation. (if I could figure out how to have memory store the 1st number and action1 and 2nd number all together) Or would eval(document.calculator.display.value) do it for me.

## JQuery :: Run PHP Script After 4 Form Fields Entered And Form Not Submitted?

Nov 12, 2010

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.

## Preserve User-entered Quote Marks In Form Fields?

Apr 10, 2010

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?
