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 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.

For static files I use as
file: {
required:true,
accept: "png|jpg",
},
How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.
<input type="file" id="tval_1" name="tval_1" class="required accept" />
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 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 RelatedThe 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 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.
Here is the current JavaScript I am using.

Code:
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).
Here are the fields I need to validate:
My js (validationB.js) file:
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 already have the remote check working and it works fine. But the catch is that I want to allow submission even if my check returns false.
All I really want is to show a warning if the remote check returns false.
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 found something here, but I'm not good at javascript, and i don't know which part of the code is the right! I need only for Checkboxes!
[url]
I need something like: onclick="check_if_at_least_one_is_selected()"
There is only one <form></form> and all checkboxes are same type...
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.
<script type='text/javascript'>
function isNumeric(elem, helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}}
</script>
<form>
Numbers Only: <input type='text' id='numbers' action= "desktop.html"/>
<input type='button'
onclick="isNumeric(document.getElementById('numbers'), 'Numbers Only Please')"
value='Check Field' />
</form>
I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. just for testing purposes I've put return false on everything so it displays a message when everythings ok.[code]
View 3 Replies View RelatedForm 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'm using the following javascript code to validate a form:
My HTML code is as follow:
The fact that my using xhtml strict I'm having an error when validating my html file. Can't use name attribute in form.
I have this form validation code
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 have an image validation script that im working on. This is what i have so far...
<script type="text/javascript">
<!--
function validate_form ( )
{
var imgcheck;
valid = true;
if ( document.editavatar.avatar.value == "" )
{
alert ( "Please Enter an Image Url!" );
valid = false;
}
return valid;
}
//-->
</script>
How can i add to that so that it checks if the avatar field has the words png, jpg, gif and bmp, and if it doesnt, valid will be false. So in other words, if it does contain png, jpg etc it will return valid.
I want to validate a form. In the form is a text field named 'extra[]' where the user inputs a number. The number is what I want to validate.
However, the 'extra[]' field is dynamic and does not always appear in the form.
If it appears, there may be only 1 occurrence of it which means it's then not an array but there may also be multiple occurrences of it.
I have a script that validates (and work as it should) if the 'extra[]' field occurs multiple times and is thereby an array, but I can't figure out how to validate the 'extra[]' if there is only 1 and to not throw an error if it's not there at all. Code:
A non leap year can be divided by 100. But a leap year is divisible by both 4 and 400.This seems so simple yet I can't nail it. I'm taking an accelerated Javascript class and I was able to do all the problems up to this one. It's confusing me, or it may be that I've been up since 2 working on homework and getting ready for another test.

View 2 Replies View RelatedAjax and jQuery is something I'm new to, but PHP, Javascript, and MySQL I'm pretty well seasoned with.For starters, I want to create a simple form where there are these fields:Name (text field)E-mail (text feld)Zip Code (text field)Cell Phone Number (text field)Phone Carrier (dropdown menu)Thing is, I want to check the database to see if an e-mail address has already been entered. I'd like for that to happen after they enter the email address and tab or click out of the e-mail text field. For instance, after they enter an e-mail address and tab to the Zip Code field, the script queries the database to see if that e-mail exists already. If it does, it notifies the user and greys out the submit button. If not, they're allowed to finish filling the form out and submit. It'll be a huge time saver if this Ajax script is in place.
View 1 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)

I need to validate the form, I am getting started by validating a simple username field. I have written the code but it does not seem to work for me.

I have an order form where a customer can select a number of artwork prints supplied by different artists and suppliers. The name, price, postage amount and other details for each of the prints are held in a table in a MySQL database. As postage amount may vary between prints and suppliers of the prints we must have the customer select postage per print - not the amount just yes or no. The customer may select as many of these prints as he desires - printa, printb, printc, printd etc. through to printz. Many of the prints are provided by separate individual suppliers and must therefore have postage paid for each ordered print and this is automatically added by the order form. However some prints are provided by the same supplier and only one postage fee needs to be chosen (yes or no), so these are not automatically added and the customer must choose to pay postage on only one of the prints (not all 3 if he orders 3 of them).
So for postage purposes I have a postage code on the table in the MySQL database. For example printa, printb and printc are all supplied by the same supplier so each have a linked postage code of A. Similarly others may also be linked using different postage codes e.g. printx and printy may have a postage code of B. So whenever a customer chooses a print that does not have a linked postage code then the postage fee is automatically selected for him and charged to the total. However where prints are linked to the same postage code we must allow the costomer to select postage (yes or no), but we must force him to select yes or no for at least one of the linked prints.
So to do this I need a javascript validation alert to force the customer to choose yes for postage for at least one of the prints, not necessarily all of them, where they have a linked postage code. To do that I can add the the postage linked code as an array for each print selected to a form hidden field so that my javascript can use the field as follows: <input type="hidden" name="postagearray[]" value="<? echo $postagecode; ?>">
