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

View 3 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
}
I need to edit the plugin so that the number fields will accept decimal numbers with no preceeding digits. For example, I need .8 to be valid [URL].
View 1 Replies View RelatedIs there a formatting or rounding technique to specify the number of digits to display after the decimal?
View 2 Replies View RelatedI wrote a regex to edit a decimal number. you're allowed 1,2, or 3
digits before the decimal point, and 0,1,2,or 3digits after the decimal
point. Of course, you can't enter a decimal point without at least a
digit after ("5." is invalid). So here is my regex
pattern=/^d{1,3}(.(?=d))d{0,3}$/
This works fine for every case except an integer. In other words, it
tests false for entering 5, or 567.
I don't see why it tests false for integers. I'm allowing 1-3 digits
before the decimal point, then a decimal point only if the next
character is a digit (the lookahead clause), and then 0-3 digits after
the decimal point.
I've gotten around this problem with other javascript code around
the regex, but I'd just like to know why this "clean" solution doesn't
work.
Suppose I do (5 * 0.039) + 0.59, then the result is 0.7849999999999999 - but I want to round it upwards and should have only 3 digits after decimal point. I found out that using toFixed(3) will get it to be 0.785, but the problem is that it add x.x00 for some numbers where there aren't much decimal numbers. Is there a way I can remove the 0's?

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 8 Replies View Relatedi'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;

How can I validate a text field to make sure it contains only digits?
View 4 Replies View RelatedI 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 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

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.

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;

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.
View 3 Replies View RelatedIm trying to find a code for such a ''Reckoner'' script as it is here: [url]
Of course the datas should be instantly updates when exchange rates between currencies changes and it does changing very often (daily). I thought I could ask their webmaster for the code but the script is not the same to what is needed because there should be some rounding also done to the nearest 5. What do I mean with ''nearest 5'' is shown here:
[url]
I have seen those four scripts already but they are different:
[url]
Its very important for me that updates are being changed by trustful source (website) which will really stay up 24/7 forever and will get (this source) new exchange rates instantly. If source would be unavailable that means the script on page of my website would be unavailable too. Also I should not need to republish page (or entire website) when the datas are changed. When I mentoined changes should be instantly, on html page, I meant when page (or website) is being reloaded. So since the source of exchange rate is important, the code should not contain any values at all (except for rounding) because those values (exchange rates) are changing very often (daily).
