JS :: Multiple Field Validation ?
Sep 7, 2010
My code seems to work individually it is when I try to do multiple input validation that everything goes wrong.I have tried at the moment to cut it down to just two validation inputs to simplify things, but the more I try and play around with it the worse it seems to get.I know a lot of people post about this but I have tried comparing to other people's codes and solutions and just can't work out what is wrong.

Also if any of these fields are left blank i don't want to be able to go to the next page on clicking the submit button

I'm only validating one (Consent) radio button with this code but I need to validate multiple different questions/buttons.
<script>
function getRBtnName(GrpName) {
var sel = document.getElementsByName(GrpName);
var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
} return fnd;
}
function checkForm() {
var chosen = getRBtnName('Consent');
if (chosen < 0) {
alert( "Please choose one answer when you are asked to select a number." );
return false;
} else { return true; }
}
</script>
<form action="congratulations_aff.php" method="post" name="congratulations_aff" onSubmit="return checkForm()">
<table border="0" cellspacing="1" cellpadding="0">
<tr>
<td colspan="3">I consent to providing my electronic signature.</p></td>
</tr>
<tr>
<td colspan="3" valign="top">
<input type="radio" name="Consent" value="Y" />
Yes
<input type="radio" name="Consent" value="N" />
No
<table border="0" cellspacing="1" cellpadding="0">
<tr>
<td>I consent to electronic receipt of my information reporting documentation.</td>

<td valign="top">
<input type="radio" name="Consent1099YesNo" value="Y" />
Yes
<input type="radio" name="Consent1099YesNo" value="N" />

I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.

I'm using the validation plugin available here and seem to be encountering trouble in IE7. The validation is not occuring and my forms submit. Not what I want.The functions below are working fine in FF3, Opera 9.0, Chrome, & Safari.I'm going to guess this is a result of some misplaced character or ...??? Maybe a second set of eyes will spot the error.
Code JavaScript:
//
// Validate Form Fields

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;
[code]....

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.

I'm trying to display an alert if a form field has a value in it. I got this function, and looked at a half dozen others that are virtually identical They ALL claim to work This doesn't and I have no idea what I've got wrong Can somebody tell me what's going on? The function gets called onSubmit, and the Alert "xxx" is displaying.
[Code]...
And while I'm in here asking questions about javascript, can somebody tell me how to do an alert that'll append a value to text? For example... Alert ("xxx" + form.newfile0.value); How do I write this so it actually works?

I have a three field contact form on an HTML5 page. Using CSS3/HTML5 techniques, the fields change state as the info is entered properly (green OK symbol if good, red "!" if not, etc). That all works as expected in all browsers.
My final hurdle is preventing the form being submitted with nothing entered in the fields. I have done hours of research and have tried several ways of writing the checkFeedbackForm function. My problem is that none of the solutions I've found are recognized by FireFox (mac and pc) and IE. They just ignore the javascript and allow the empty form to be emailed.

Form validationhaving had a number of responses to my initial request for a template for a simple client-side JavaScript form with basic field validation it seems that this simple request is far from simple.so, collating all of the not-so-simple comments that I have had heres a revised request
Is there anywhere that I can find a template JS script that will provide me with a form that has the most basic of fields on it first name, surname, telephone.e-mail etc that comes with field validation? The users will predominantly have hotmail, yahoo etc e-mail addresses Not all of them will have IE web browsers Not all of them will have Outlook Express as their mail client
The form fields MUST BE VALIDATED ON THE CLIENT-SIDE as there is no server-sideaccess and the site that the form is then be posted to will only accept validated field data. Or would it be simpler for someone to provide me with plans for a engine that would provide light-speed.?

I have some problems with validating form in javascript.
I have a following HTML code:
What I want in validation is to check all the field in form (check for required fields etc). I want to show user error message in div tag with id='poruka'.
Part of code of function ValidirajFormu:
So, validation works OK, but message is not written in div tag. Only if all fields are correct, form is submited, but there are no error message.

I am having difficulty with my javascript data validation for a birthday field. The error is coming up correctly, but the result is never returned as true. Even if I enter the date correctly, the error "Invalid date! The correct date format is like '01/01/2004'. Please try again." comes up. This data validation is for a contact form that i've developed for a personal site. Can someone please stear me in the right direction? I feel as if this is a simple syntax error, but I have looked at it for hours and cannot seem to find any error in script or the functions.Here is the code:

I need this function to accept decimal values (e.g., 2.5 ok, not just whole numbers between 1 and 5).

I need to invoke a method when a field validation is either successful or unsuccessful. I have managed to get the function to run if the field validation fails by using the following:
$('#myform').validate({
rules: {
client_name: {
[code]....
But how do I invoke a method specific to a field that triggers when the field validates successfully? I need to invoke showBigGreenTick(fieldname) for the fields that are validOn another note, I find it very strange the the documentation is so poor regarding this validation. To even find out that there was a "messages" option for validate was found on another website.

The phone number field must match a 7 digit or 10 digit(with area code)phone number. I want to be able to include paranthese and/or hyphens for the valid phone number.
function checkForm1() {
if (document.forms[0].firstname.value.length == 0) {
alert("You must put in a first name");

All I need is a script to check whether a field contains an exact code. For example,
A user goes through a game, collects pieces of the code - In this case random numbers or letters to form a 9 digit code.
The user can then enter this code into the field, hit submit and told whether they've cracked the code or not.
So basically something like, if this field contains "123456789" then go to WellDone.html but if it contains anything else other than this code then go to BadLuck.html ,
any ideas? Code:
