Field Validation As Float With Certain Integer And Certain Decimal
Jul 23, 2005
i 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 have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.
I want javascript function that could convert from integer to float e.g if user enters 10 then it should convert it to 10.00 or better 10.000. If user enters 10.0123 then it should convert it to 10.0123.
I want to use a result for furtherer calculations but only want the whole number and not the decimal portion. In Excel there is a function "=INT(A1)" this ignores the decimal values in cell "A1",
e.g. if cell "A1=5.345"
and I use the following function in cell "A2" "=INT(A1)*3" I get the result "15"
the user enters his values in 4, 5,25,6,00 or 6,05 etc.(using the , sign)and the max validation only takes integers. How can I still make the max validation with the , sign and float values? The users isn't allowed to submit the form if the value is greater than the max value specifyed.
This should be simple, but it's not working for me! The relevant code is beneath. This code is on my html page directly under the input field:
input = document.getElementById('hiddenInput'); var inputInt = parseInt(input.value); if (inputInt != 0) { setClick(inputInt); }
(I've tested it to make sure it sees the input object and that it has the correct value. It does call the setClick function appropriately, too.) This code is in a javascript file called in the <head> of the html page:
[Code]...
setClick() and resetAll() work great when I hook setClick() up to a link. When I try to grab the value from the input field, it doesn't even call resetAll(). I've assumed that it's a problem with converting the value to an integer, but I could be wrong. Does anyone have an idea as to what's going on?
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 learn how to do this one thing with JavaScript and can't seem to find anything on the internet. I have learned about loops and arrays and some other useful stuff. I've been looking for 2 days straight. I have gotten close though.
I am trying to have a textbox on the page and a button below it. A statement above the textbox should ask the user to enter a positive integer and then click the button. When the button is clicked the results from 0 to that number should appear below the button. Should look like this
please enter positive integer. 6 BUTTON1
1 2 3 4 5 6
I have been trying night and day for 2 days now and It's driving me insane.
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
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.
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,
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?
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.
I want to pop up message incase of validation failure of form field.If I use document.write("name shold be between 2 to 15 char only")it redirects to new page and gives this message..........if I use alert than incase or 2 or more validation fail it gives multiple or one by one alert boxes.I want to to displey my message near to field...............
function validateForm() { var x=document.forms["regform"]["email_id"].value;
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.
