I need to do javascript money validation for a field. the condtions are
1) depending on the Locale (not sure if this can be done in JS like US,Germany..)
2) verify if it has $,pound symbol, yen symbol..
3) group the digits either like 00,00,000 or 000,000,000
4) accept 2 digits decimal 000,000.00
I have a problem in asp application validation. My textbox only accepts numeric value.It should not accept empty field and negative values and charcters.I am not aware of IsNan function.
View 8 Replies View Relatedi have to do in the onkeypress or in onchange the float (real) field validation I try something:
function ValidaCampo(nomeCampo,TotInteri,TotDecimali)
{
DecimalPos=NomeCampo.value.Indexof(',');
Lungh=TotInteri+TotDecimali+1; //sum the ineger + decimal +
decimal separator
if ((window.event.charcode==',') && (DecimalPos>-1))
//i think exist a decimal separator so i don't add any other
else
if (DecimalPos<>TotInteri+1)
//i haven' t insert too much integer
else
if i haven't add any decimal, i add a separator with two zero value
else
if nomecampo.length<>Lungh
//error
}
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]....
that a javascript which is validating a phone number accepts only digits but if the text field is left empty it should accept the entry as an empty entry...
View 2 Replies View RelatedI have 2 fields in a form, field1 is type hidden while field2 is type text.Both will have numbers in them. I need to compare these 2 in my form validation and having issues getting it to work right. If I do something similar to the following:if ((passForm.field1.value) < (passForm.field2.value) ) {alert.....It runs, but is running the validation, but is reading the values as text and literally left to right.
so for example
If field1 = 12 and field2=3 it does not run the alert (wrong)
If field1 = 12 and field2=100 it runs the alert (wrong)

Very simple, but useful - I just came up with this in answer to a post:

document.all ? k = e.keyCode : k = e.which;

}

provide the HTML/Javascript to ensure a field can only accept numbers? (I don't mean post-submit validation, but literally the field only accepts numerical input.)
View 4 Replies View RelatedI have an input in the form, where i have to do the following validations.
1) see if it is a number
2) allow digit grouping wither like 00,00,000(Asia format) or 000,000,000 (us format)
3) allow 2 decimal points 000,000.00
4) if the money does not conform to this format return false
need to calculate decimal values
example 42.925181855342466 + 58.64
but i get this $58.64$42.93, i know js is easy on int values
Code:
Esanda.prototype.calculateFornightCharge = function(payIndex,dueIndex)
{
var oThis = this;
alert("Pay index" + " " + payIndex + " " + "Due index" + " " + dueIndex);
var pi = (payIndex-1);

I am unable to solve two problems creating a contacts form using dreamweaver CS3. My other problem is posted under the heading, "Modify code created with Dreamweaver CS3, to compare two text feilds". For this posting, can someone please tell me how to modify my code, pasted below, so that the "First Name" and "Last Name" text fields are restricted to accepting only alphabetical characters.
Here's my current code

i'm fairly new to regular expression and want to know if it's possible to check a text field value. I need to only accept value between 0 and 20. I've got also a problem with the 0 value ... guess the script think it's false :
if(!Number(document.data.f_cat_1.value) || document.data.f_cat_1.value > 20){
alert('Your must enter a numeric value between 0 & 20 pts!');
document.data.f_cat_1.focus();
return false;
}
I have a small piece of code (taken largely from W3 Schools)that checks that there is a decimal point entered in a form field, but what I really need is to check that the number entered ends in 2 decimal places.
e.g.
10 is Invalid
10.00 is Valid
My current code is below. Can someone explain what I need to do to ensure that the user enters a number including two trailing decimal places please?

I am trying to setup a textbox to only accept specific keys. The problem is, some of the Function keys are reading as the same values as letters.Ex.
112 - F1 - p
113 - F2 - q
114 - F3 - r[code]....
Is there another way to allow the function keys without enabling all matching letters as well?
I need to validate two forms containing multiple input fields but want just one error message if any of the fields are left blank, the page is required to submit the users details (registration form). 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
View 1 Replies View RelatedI'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.

I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?
Not exactly sure this is the right forum to post this but just to give it a shot.I am relatively new to programmming...I am currently working on a web appliation using MySQL DB and use PHP/SQL.I have a web form i have created. What i want to achieve is that when a user fills in one of the fields...a text field, i want 8 other fields to be AUTO filled with different values related to the one the user filled in
View 2 Replies View RelatedI 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 have a field that requires validation when you press a button as follows:
<form name="form_affiche" enctype = "multipart/form-data" method="get">
.....
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?
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.

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.
