Simple Email And Phone Number Validation From Form
May 17, 2009
I am in need of some very simple javascript to validate email address and a phone number from a form.
The email address only needs to:
1. Check that the box is not empty.
2. Check that the text imputted contains an '@' symbol.
3. Check that the text imputted contains atleast 1 Period.
The phone number only needs to:
1. Check that the box is not empty.
2. Check that there is no more than 11 characters.
3. check that only numeric characters have been inputted.
I would like it to report (failure) back as text on the page under the box that has the problem rather than a window.
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?
The following is a simple form with text boxes..Used java script to check for nulls but how to check my phone number for only integer values ie numbers
Another newbie question here, I'm sure. I'm trying to modify an existing form with an existing validation scheme. I have to put in something so that the phone field that is entered actually contains numbers. There is no need for dashes, parens or any other divider, but we don't want to exclude them either.
I have gotten as far as this: [URL]..110620_1a.html (new isPhone function that doesn't break anything added at lines 119 - 127) When I try to add the call for the checking however, the entire checking scheme breaks, and the form just executes: [URL]...._110620_1.html (Added code is at lines 190-198)
i have created one simple login form with 5 fields namely username,email id,password,retype password and phone no.i have created alert message for each function,so that when there is an error it displays alert message..now i have to replace all alert messages with inline validation(displays errors beside textbox).
below is the code for simple login form having fields username,email id,password,retype password and phone no. i have done inline validation forcheckName() .i am not getting for the other fields can u tell me how to do it..
Need Phone Number Validation for my JavaScript, i can't work it out It currently has E-mail, Surname, Address and Name validation, This is my code at the moment:
<script language="JavaScript"> function echeck(str) { var at="@"
i was doing this in php but then i decided to do it in js but i am not familiar at all with it. i am trying to validate a phone number. it is supposed to be in the format xxx-xxx-xxxx.
I want to add a min length of 9 validation for a phone number. Thats once spaces have been stripped out.[code]What do I need to add for the min length? (once spaces have been stripped out)??
I have a phone number field on my form that needs validation, but I'm not sure how to code this. I have the following function to validate a first name is entered and last name. The phone number field must match a 7 digit or 10 digit(with area code)phone number. I want to be able to include paranthese and/or hyphens for the valid phone number.
function checkForm1() { if (document.forms[0].firstname.value.length == 0) { alert("You must put in a first name");
I want to validate phone number in my project. I include some validations. Furthermore i want to check whether it exactly contains ONLY 10 digits.nothing more and nothing less.How should i include that?
if (document.form1.phone_number.value == '') { alert('Please fill in phone number!');
I am a Javascript newbie and I'm trying to implement a very simple form validation function, but for some reason it won't work. I must be doing something fundamentally wrong here. Maybe somebody can hint me into the right direction? My code looks like so:
function validate_form () { valid = true; var re = new RegExp(); re.compile("[A-Za-z0-9._-]+@[^.]+..+"); if ((document.form.author_name.value == "") || (document.form.author_email.value == "") || (!re.test(document.form.author_email.value)) || (document.form.author_message.value == "")) { alert ("Please fill in all required fields."); valid = false; } return valid; }
The tricky bit is the email validation using the regular expression. Apart from that it all works.
I am trying to do a simple email validation for a form with javascript that doesn't seem to work. I have tried pasting it into both the head and body of my html document. I have also tried unsuccessfully to link it as an external .js file. I have tried numerous scripts that I have found online but none have worked. I am new to programming and don't have much experience with javascript.
This is what I have so far, it is a template I copied from my working E-mail validation. I'm assuming I have to make it so it's just an array of numbers but I really don't know Java too well.
Essentially I just want numbers only to be accepted into the phone field. code...
i have some script java script which is working but i want to do it some thing else
[Code]....
This script is working for email validation also if email box is empty it says to fill it i want that for all if some one left any box in form it says fill that. i have tried many ways but failed that's why posting here. and the last function is for contactno INPUT field so one can only put number in the field. HTML CODE
I have a form which mostly works and validates with javascript Name, details, email, etc. However the email bit is happy to validate with just @. instead of a@b.net/com/whatever. It's probably a really simple fix, but I'm still new to javascript.. Hopefully someone can point out what I need to add / change in the following section of script.
i'm not sure if something like this has been answered before, so sorry if this is a repost.what i'm trying to do is have a div become visible on an invalid form entry.here is the code that i have:
Code: function validate(c_form,email) { var reg = /^([A-Za-z0-9_-.])+@([A-Za-z0-9_-.])+.([A-Za-z]{2,4})$/;
I am trying to develop a form with email validation but i am recieving an error which is this

I am looking to add an email validation to my new user registration form. Currently, we do not validate (or activate) a new user via an activation link in the email. We don't have that process. I'd like to get my hands on the code to randonly create a security code and the actual code to sent the validation email. Can anyone help me out here? I'm absolutely new to PHP or ASP coding. I do know some HTML.
Im building a simple form that should check for two fields (not empty), however it seems the form is not being activated as no errors are being produced.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Guestbook</title> <script type="text/javascript"> function checkform() { if
I tried searching for this but couldn't find anything that looked correct (Although, I might not have a clue what I'm actually looking at!) I have a fairly simple forum system running as part of my site as part of the member system memberkit. I would like the forum to be public - members can post to the forum, and the public can post to the forum by putting in a name and email address.....
but....I would like some simple code to either block out, xxxx out, or remove entirely email address and phone numbers from forum visitors that are not members. I'd really like to show a gray block over the phone or email address that says "please login to view this information"
Now as part fo the system, I do have IFEQ tags available to determine if the user is a member or not, so I've got somethnig to execute the code on, but I just don't know what the code needs to be.
I've seen this done on other forums before for links and such, I'm just not sure how to do it. I'm guessing it would need to read the whole post message and look for certain strings of characters, etc. [URL]...
