I am using this code to validate a form to check that only numbers have been entered but when I enter alphabets the javascript raises an error but still submits the form.
function check_email(mailstring) { valid = "1234567890qwertyuiop[]asdfghjklzxcvbnm.@-_QWERTYUIOPASDFGHJKLZXCVBNM"; for(i=0; i < mailstring.length ;i++)
[Code]....
at the moment its checks that someting has been enetered in all these fields,
what would be the best way to check that the email or phone nummber had been entered?? will not send if nothing enetered, but will send if one or both have been enetered?
I am constructing an HTML questionnaire and one of the questions requires people to rate some choices from 1 to 5, where 1 is their favourite and 5 is their least favourite:
Car Bus Taxi cab Train Airplane
Each choice has an INPUT TYPE=TEXT tag to contain the response. I also have a function that is called ONCHANGE in order to check that a number is entered between 1 and 5:
function CheckNos(obj) { if(obj.value.match(/[^d]/) || obj.value<1 || obj.value>5) {alert("Please enter a number between 1 and 5");obj.value="";return false} }
This works fine, but ideally I would like a function that could check ONCHANGE that someone has not filled in the same number twice, for example answered "1" for all of them. They are only allowed to use each rating number once, so rating their choice 1 to 5.
Can anyone suggest a short function that could accomplish this easily? Could I use some kind of array with 5 elements and allocate a flag value once that number had been chosen, then check that the value had been set?
I have the following code that I wrote myself (except for the function isNumberKey). However, I don't know how to actually add the numbers together. My plan is to store the value entered in the forms as a variable, then manipulate the variables to get my final number. The final number would be stored in variable named Total and would be displayed after Total: at the bottom of my page.
The following Javascript will return an error message if the user did not enter any value into the zip code field. The form will submit even if user entered only 1 character. Does anyone know how to change this to at least minimum 5 characters must be entered into the field?
...} var fname = "CustomFields_17_2"; var fld = document.getElementById(fname);
I have a form with a text box where users can enter a 10 digit code. The 10 digit code can be just numbers/letters (eg. 0123456789 or abcdefghij) or it can be a mixture (eg. 0a1b2c3d4e). What I would like is if the user enters a code which is a mixture of numbers and letters then the submit url goes to mixed.php If the user enters a code which just has letters or numbers then the submit url goes to sole.php change the url from selecting radio buttons.

I'm trying to make sure that when a user enters information into my textbox, that when the textbox loses focus then it checks to make sure that they entered numbers and not text or other characters. Numbers only....Any suggestions?
I currently have a form named "survey". I found here a JavaScript to validate my form.
I am having serious issues with this script, either it won't execute at all (the form doesn't work, as well as the validation) or the form submits without validating the form.
I don't know why it's not running the validation js first upon "submit", it goes straight to the "thankyou" page specified by the php (let me know if php needs to be posted). I've check my syntax over and over, I can't see anything.
I'm trying to have a "tell-a-friend" form where one requires to enter his/her first name, surname, email and a friend's email � with option of forward to to other 4 friends (total 5).
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 putting some validation on some forms at work. The users have asked to put something in place to make sure that if you enter something in on field that you must enter something in the corresponding field.
Example : Lets say there is a Company field and a Position field. Well they would like that if you enter a Company you should enter a Position and the other way where if you enter a Position you just enter a Company.
Ok so thats easy enough I did something like the following.
if((form.Company1.value=="") && !(form.Position1.value=="")){ alert("Enter a Company into the Company field for row 1 or enter N/A"); form.Company1.focus(); return false; }
Well now they want a message box to give the user the option it ignore that they have a blank field, and more or less want a �hey just to let you know, you didn�t put anything here
I have an issue with a form I am creating, I have many check boxs where at least one of the 2 needs to be selected and the final one has to be selected for the submit button to become active
This is the javascript I have atm to do this:
I cant seem to get this to work, forgetting about the 3rd checkbox for now
I've got a url field on a form that is not required but if it's entered I want it to be correctly entered to keep errors down. This is for an admin screen so I'm not concerned about cross site scripting attacks or anything, I just want to make sure that the URL is properly formed.
So far I've come up with the following code snip but I wonder if anyone can comment on it or perhaps come up with some improvements. Code:
I would like to add a plausability check for numbers with JS, but regex is not really a strong knowledge of mine. Can anybody give me a hint, or lead me to the right script for doing this?
Inside the form a user can place a price which I would like to be only a number, smaller than 100000 and there should no , or . be inside the value. otherwise they should see an alert message. Code:
I am re-developing my website and want to use some Ajax/jQuery in it (so I am learning as I go) and I am not sure if this is possible so that is my first question:I have a registration form and I would like to know if after the person registering has completed their first and surname and the 2 sections of their postcode if I can use jQuery to run a PHP script to see if they are already registered before waiting for the form to be submitted and running a script then.I am thinking onkeyup (or similar) after the last field is completed but I don't know how that would work needing to also use 3 other field values.If this is possible, can anyone give me any ideas of examples that do this or how I can go about passing all the variables and running the scripts at the correct time.
