Calculation Of Form Field Entries?
Jun 18, 2011
I am a novice user of Expressions Web4 and am attempting to build a form that makes calculations of field entries and displays the results in designated fields. Specifically, multiplying the entry in the pmt_amt field by .03 and placing the result in the srv_fee field, then adding the entry in the pmt_amt field to the result in the srv_fee field to show the resulting sum in the total_pmt_amt field. I have created functions in JavaScript for both calculations and tied them to onClick relative to a button btn_srv_fee.
I used this method by searching online for an appropriate method and tweaked results for my application. Below is the code for what I am attempting to do. Upon making an entry in the pmt_amt field and then clicking the button, there are no results in neither the srv_fee field or total_amt_field. Below is the code for the functions and the associated section that identifies the fields.
<script type="text/javascript">
function multiplyNumbers(pmt_amt, .03, ResultField1)
{

The attached page has 3 entries to be made. Now I want to validate them, that is, if the form is submitted with even one blank field an error must be indicated. I have put the validation code but it doesn't work upon empty form submission.

I have a form with 12 fields. This form submits the information for registering a student for courses that we offer. Currently, it only handles one registration at a time and is kind of clunky.I want to present the user the capability to register more than one person at a time. Essentially adding multiple users' info at once before submitting the form.I also want to have an area above the form that shows a list of people that they enter in a select,which will later be modified to have checkboxes so they may remove them, if needed.

I'm trying to expand on a tutorial where Jonathan Stark creates a database using JS, CSS, and JQuery. A complete explanation of the code can be found in chapters 4 and 5 here:Building Android Apps with HTML, CSS, and JavaScript (sets up the HTML).Building Android Apps with HTML, CSS, and JavaScript (sets up the DB storage).Stark uses a form for the user to enter data, then the attached js file inserts the data into the SQLite database:
HTML Code:
<div id="createEntry">
<div class="toolbar">
<h1>New Setup</h1>
[code]...
how can I redirect the form to a different database script on a different or same page as this database code? I want to have multiple forms going to different tables, and I want the database scripts kept separate. I just don't understand how the form data knows to be inserted into this database. If I duplicate kilo.js, rename it kilo2.js and use different field names, and attach it to the forms page following kilo.js, then kilo.js is ignored and the original form does not work.

I'm building a form that is calulated based on the options selected with a javascript form. This is my first attempt at something like this so I'm a bit lost at the final update.
First to be sure I'm on spot here is the javascript I'm using to update the form - <script>
function BDWcalc ()

I have a form which must calc the difference between 2 date fields and
return the result in a third field. I have the following code but it does
not seem to work. Can anyone tell this total newbie where he is going wrong
or suggest a more elegant way of doing this.
<head><script>
function doit(oForm, usrInp)
{
var one_day = 1000 * 60 * 60 * 24 ;
var userDate = new Date(usrInp)
var dueDate = new Date(usrInp)
diff = dueDate - userDate
oForm.diff.value = (diff/one_day) + ' days'
}
//-->
</script>
</head>
<body>
<form name="a">
<input type="text" name="userDate" >
<input type="text" name="dueDate" onblur='doit(this.form, this.value)'>
<input type="text" name="diff" onfocus=this.blur();>
</form>

I have a form which i want to calculate entered values in text boxes. What i want from the below code is ;
1- i may have 100 textboxes so the javascript that i use may be inefficient for larger amounts. Does anyone have more encapsulated solution for multiplying and adding to total amount?
2- when i click check boxes their values must be added to total textbox below.
3- How can i calculate VAT and grand total? with $ sign infront of them ?
its seems easy but couldn't manage to do as i am not a programmer.

I am attempting to provide the user with an estimated price value given their input in 2 form fields.
One is a dropdown and the other is a radio button set. They will output to a text box
I was able to achieve the desired result using integers as the text box options. However, when i replaced them with strings, the calculations no longer work (obviously )
My problem are:
1. Associating integer values with the word items listed in the dropdown. Example: "standard" should have a value of 100, "deluxe" =200 etc...
2. actually getting the calculation to complete using both dropdown and radio button elements. I'm not sure what logic to use to get it to total out. I essentially want the selected plan flat rate cost ($100 for "standard", $200 for "deluxe")to be added to the additional units cost ($50*number of units selected)
Refer to the reference URL for my intended layout and functionality [url]

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.

The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
function validate_form ( )
{
valid = true;

my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:
//Event Registrations (Variable Declarations) found in validation_chkr.js
//Validate Entire Form using validate_join()
function validate_join()

I have made a script where you can add extra fields, and next to the row is a span that automatically displays the outcome from a calculation of three fields in that row. i.e. Q x (B - A) = total. Here is the bit that does the calculation:
function advCalc(selected) {
var result = Number(document.formmain.elements["quantity"+selected].value) * (Number(document.formmain.elements["provideamount"+selected].value) - Number(document.formmain.elements["supplyamount"+selected].value)) ;

Is there a way I can calculate a field in a form based on another field in
the same form. When clicking submit, both values should be posted to the
next page. I want to be able to type in a value in one field, and
automatically in a second field the value*1,36 should appear.

I am having trouble with the following code. Right now the user clicks the button and it shows all of the blogs from the blog array. However I want it to just reveal 2 then two more and two more and so on as the user clicks button. I have tried multiple things but can't seem to get it right. Most of the things i try either reveal the entire blog on start or when the user clicks hides all of them.

Have form where visitors fill in a few '<input type="text"> fields that require simple integer numbers. (I may be making a mistake in just using text fields? Please mention in reply in conjunction with main question below).
Here is a typical row:
<td>Box of dozen red pencils</td><td>$1 per box<td><td>Number of boxes wanted</td><td><input type="text" name="redpencils" id="redpencils" size="6"></td>
There are four colours and all are different prices per box. Blue are $1.20, Yellow are $1.50 and green are $1.70 per box. The form says that a minimum order is $10. I want that a warning comes up and submission fails if the entries add up to less than $10. I have simple default browser warnings come up if the required fields (like name, phone number) are not filled in. I want similar if the orders do not add to $10 or more.

I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.
When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?

I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

I work for a very large company that has zero communications between IT and the employees...so there is very little possibility of having any code changed.I need to use a web based system that submits orders for my department. The problem is i must order by "task number". I could have 20-30 task numbers so to complete the order I need to go to my company's page and fill out 15 form fields and submit for each task code. It is a terrible pain. 14 of the 15 fields are the same for each order... only the task code changes.
