JavaScript - Simple Javascript Form Validation
I'm trying to do a simple validation to see if the field is blank, if it is, I want to write a message to a div. I've added the function call to an onclick. It seems to be set off no matter if there is a value or not, and what's more, the fields are clearing out when the link is clicked. My brain is mush right now, so what am I missing?
Code: function validateThis() {
document.getElementById('messages').innerHTML = ''
var theMessage = '';
var reqMsg = 'must have a value.';
for (var i = 0; i <document.theForm1.elements.length; i++) {
if (document.theForm1.elements[i].value = ' ') {
theMessage += document.theForm1.elements[i].name +' ' + reqMsg +'<br/>';
}}
document.getElementById('messages').innerHTML = theMessage;
}
Similar TutorialsI'm trying to make an xhtml form that validates itself through a javascript function. I have the form up but for some reason I can't get it to validate. I'm not even sure if I linked things correctly. Here's what I have: the xhtml file <?xml version = ″1.0″ encoding = ″utf-8″ ?> <!DOCTYPE html PUBLIC ″-//W3C//DTD XHTML 1.0 Strict//EN″ http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd> <html xmlns = "http://www.w3.org/1999/xhtml"> <head> <script src="gas24.js" type="text/javascript"></script> <h2> Registration Form </h2> <title> Javascript Form Validation Homework </title> </head> <body> <table border=""> <form name="validation_form" method="post" onsubmit="return validate()"> <tr> <td> <t>Name: <input type="text" name="YourName" size="10" maxlength="10"/> </td> </tr> </br> <tr> <td> E-mail Address: <input type="text" name="YourEmail" size="10" maxlength="24"/> </td> </tr> </br> <tr> <td> Password: <input type="password" name="YourPassword" size="10" maxlength="10"/> </td> </tr> </br> <tr> <td> Re-Type Password: <input type="password" name="passwordConfirmed" size="10" maxlength="10"/> </td> </tr> </br> <tr> <td> Your Gender: <input type="radio" name="MaleBox" Value="Male"> Male <input type="radio" name="FemaleBox" Value="Female"> Female </td> </tr> </br> <tr> <td> Comments: <input type="text" name="Comments" size="100" maxlength="500" value=""/> </td> </tr> <tr> <td> <input type="submit" value="Submit"/> </td> </tr> </form> </table> <p></p> </body> </html> The javascript file: I've tried two things. This: <SCRIPT LANGUAGE="JavaScript"> function validation() { var x=document.forms["validation_form"]["YourName"].value; if (x==null || x=="") { alert("First name must be filled out"); return false; } } And this: function validation() if ( document.validation_form.YourName.value == "" ) { alert( "Please type your name."); valid = false; } if ( document.validation_form.YourPassword.value =! "document.validation_form.Confirm.value" ) { alert ( "Please confirm your password." ); valid = false; } I would greatly appreciate it if somebody could tell me what I'm doing wrong. Hello, On my client's site: www.twdcycling.com he wanted a place where people could make suggestions for his blog. I accomplished the simple form using a textarea field and even put a little text that clears on clicks and reappears on blur. When you go there--go to the bottom left. It also actually works. The problem is that (besides the fact that so far no one has cared to make a suggestion) somehow the form is (this is what I believe) being submitted automatically. I don't believe a human is clicking submit. When I click submit w/o clicking in the field the default text that I have in the field already gets submitted in the generated email. So I now need to work on my validation in my php file that sends the email. For background I obtained my php file from html-form-guide.com here the file is in its entirety: Code: <?php
if(!isset($_POST['submit']))
{
//This page should not be accessed directly. Need to submit the form.
echo "error; you need to submit the form!";
}
$name = $_POST['name'];
$visitor_email = $_POST['email'];
$message = $_POST['message'];
//Validate first
if(empty($name)||empty($visitor_email))
{
echo "Name and email are mandatory!";
exit;
}
if(IsInjected($visitor_email))
{
echo "Bad email value!";
exit;
}
$email_from = 'tom@amazing-designs.com';//<== update the email address
$email_subject = "New Form submission";
$email_body = "You have received a new message from the user $name.\n".
"Here is the message:\n $message".
$to = "tom@amazing-designs.com";//<== update the email address
$headers = "From: $email_from \r\n";
$headers .= "Reply-To: $visitor_email \r\n";
//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: thank-you.html');
// Function to validate against any email injection attempts
function IsInjected($str)
{
$injections = array('(\n+)',
'(\r+)',
'(\t+)',
'(%0A+)',
'(%0D+)',
'(%08+)',
'(%09+)'
);
$inject = join('|', $injections);
$inject = "/$inject/i";
if(preg_match($inject,$str))
{
return true;
}
else
{
return false;
}
}
?>
It does have some validation code, and it also is set up to handle more parameters than I needed. I tried to just pare it down to the one simple thing (I just need the user to type anything they want into my text area) My reasoning is that I should be able to go get some simple validation snippet to make it so that if there is the possibility something is causing the form to just "fire off" w/o a human clicking, the validation shouldn't allow it to send, cause the text field is empty. But one would think if that is happening my default text would allow it to send, but oddly enough, no! when I get the email (last one at 5:49 am) it was a blank email! So its like some robot is doing two things: clicking in the field to empty it and THEN clicking submit! Weird, I know. But the validation code would fix this if only I knew how. (But on another note, if I try to send an empty box my default text pops back in when I click submit--proving that its happening automatically. I tried all morning yesterday to implement a snippet from several sources. Here's a couple of examples of what I added: Code:
function emptyvalidation(entered, alertbox)
{
// Emptyfield Validation by Henrik Petersen / NetKontoret
// Explained at www.echoecho.com/jsforms.htm
// Please do not remove this line and the two lines above.
with (entered)
{
if (value==null || value=="")
{if (alertbox!="") {alert(alertbox);} return false;}
else {return true;}
}
}
I didn't modify this code at all....maybe where I went wrong here. Should "value" correspond to text area name "message"? (about the only thing I didn't try) Here's another one --this one from W3 schools: Code: function validateForm()
{
var x=document.forms["myForm"]["fname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;
}
}
this is how it was on the source site, all I changed was "myForm" and "fname" to "blog_suggestion" But when testing both these snippets separately what happened is that on submit I just go to my php page (which is just blank) I'm assuming code I'm adding is crashing the script somehow. And then of course no thank you page and no email sent. Finally here is my current php page in its entirety, followed by the form code on the home page... Code: <?php
if(!isset($_POST['submit']))
{
//This page should not be accessed directly. Need to submit the form.
echo "error; you need to submit the form!";
}
$message = $_POST['message'];
//Validate first
if(empty($message))
{
echo "Please enter a suggestion before clicking submit.";
exit;
}
$email_from = 'f7digitaldesign@gmail.com';//<== update the email address
$email_subject = "SOMEONE HAS SUBMITTED A SUGGESTION FOR THE BLOG!";
$email_body = "\n $message".
$to = "f7digitaldesign@gmail.com";//<== update the email address
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: thank-you.html');
// Function to validate against any email injection attempts
function IsInjected($str)
{
$injections = array('(\n+)',
'(\r+)',
'(\t+)',
'(%0A+)',
'(%0D+)',
'(%08+)',
'(%09+)'
);
$inject = join('|', $injections);
$inject = "/$inject/i";
if(preg_match($inject,$str))
{
return true;
}
else
{
return false;
}
}
?>
I tried to modify the validation I got w/ this to produce the "echo" message "Please enter a suggestion before clicking submit." But let's be honest, by now you know I don't know what in the heck I'm doing (it doesn't seem to matter). Form code: Code: <form name="blog_suggetion" method="post" action="send_form_blogidea.php">
<span class="bloginfotext" ><textarea name="message" rows="14" cols="12" onfocus="clearValue(this, 'Please submit ideas for our blog here—we’d love to hear from you!')" onclick="this.value='';" onblur="if (this.value == '') {this.value = 'Please submit ideas for our blog here—we’d love to hear from you!';}" ></textarea></span>
<div style="font-size:6px; color:#FFF;">sdsadfds</div>
<input type="submit" name='submit' value="submit">
</form>
Any time spent and help offered for this is greatly appreciated!! Also if you need to/want to test the field, I don't care--send me a message. I'll know someone cares! Brian I have built a signup form which has several text inputs and text areas. Their labels are set as their values. When the user focuses on the field, the label text is cleared to accept text input. When focus is changed to another field. The field checks if text has been entered. If it has not, it then resets the value back to the default label value. For example: Code: <input type="text" name="company_name" size="50" class="textInput" value="Company Name" onfocus="if(this.value=='Company Name')this.value='';" onblur="if(this.value=='')this.value='Company Name';" /> What I would like to do is have some simple javascript which checks the fields on submit. If any of the required fields still have the default label value, then I would like to change the colour of the label value in the input to red and disable the form submit until the value is corrected. Most of the inputs and text areas will accept any text, though one is an email text input. I don't think any fancy validation is needed for this email input , other than checking to be sure a '@' has been entered. Since the website that this form will be contained in runs jQuery, I have looked into some plugins for form validation. However, these seem to be over-complicated for what I need. I want to keep this as simple and light as possible. Oh, and also, I am not allowed to use anything php based as this is not allowed to run on our servers for security reasons... Any advice or suggestions are much appreciated! I am trying to have the page go to another page after clicking the submit button. is it possible to add to this function an else statement ? if form is filled then go to this page Code:
function notEmpty(elem, helperMsg){
if(elem.value.length == 0){
alert(helperMsg);
elem.focus();
return false;
}
return true;
}
Hey all, I'm finishing up a project at work that has a web-based front end. Our tightly compressed schedule has left me with no time to properly learn Javascript, so I need some help. I have two pages that need client side validation... Page 1: several text inputs, one select, one textarea, and (maybe) a checkbox There are some complex things I could do here, but for now, I just need to make users behave. The textarea must have something in it, certain select options need a Yes/No popup, and if the checkbox is written to the page (ASP determines this) then it must be checked before certain select options are submitted. I could copy some examples I've found, but how do I ignore the checkbox when it doesn't exist? Page 2: two selects and a textarea Options must be selected and the textarea must have something in it. Straightforward, except that it's a dynamic form where each element has a name + i where i is a number that increments each time the user expands the form. Will wildcards work here? I know this looks like "do my homework" but any help would be greatly appreciated. This is desired to work in IE6, but if that can't happen, I can force an IE8 upgrade on everyone. Would appreciate some help making some minor enhancements to a pet adoption form: http://pawsct.org/application.php Problem - Applicants don't read. They answer "No" to the "Agree to Shelter Visit" question, then fill out the looooong application, and get abusive when told that they're not eligible for adoption. They apply from Florida and ignore the warnings about the 90 mile limit. Text notes just don't make enough of an impact. I want to use OnChange to give an alert if someone does not answer "Yes" to agree to a shelter visit (i.e. popup "You must agree to a shelter visit to qualify for an adoption from PAWS") and perhaps a warning message (red text reminder about the 90 mile limit next to the drop-down box) if someone enters a state other than CT. Second problem - I'm a volunteer who doesn't know javascript and can't cobble together a SIMPLE, workable solution from other code samples. Any assistance that you can provide would be most welcome and appreciated. Note: we are planning a redesign of the web site and may do some more sophisticated form validation (e.g. check age, valid e-mail, valid phone) in the future. But for now, we're just looking to check a few key fields for answers that would immediately disqualify an applicant. Hi I am trying to valid a simple address, that works fine apart from the fact that it will not allow forward slash in it "/" such as: Unit 12/13 some where. In brief I want to change /^[\w ]+$/; to include a forward character in it. I am new to javascript. many thx. p.s. every time I google it they find me email address validation dehhhhh I use the following code: Quote: function validateVat_No(fld) { var error = ""; var illegalChars = /^[\w ]+$/; // allow letters, numbers, and spaces if (fld.value !== "") { if (!illegalChars.test(fld.value)) { fld.style.background = 'Yellow'; error = "The Vat No contains illegal characters.\n"; } } else { fld.style.background = 'White'; } return error; } I am a javascript begginer and would like to know what is this bit of code saying?

Hey everyone. I hope you can help me getting through this problem, because I have no idea of what else to try. I'm a web designer and sometimes modify Javascript, but my main focus is HTML and CSS, meaning I have no idea how to code in Javascript or how to write something from scratch in PHP. So I designed a form that works pretty well, and integrated a PHP and Javascript script to make it work. This is the form: Code: <form name="form" id="form" method="post" action="contact.php">
<p>Hello,</p>
<p>My name is <input type="text" name="name">, from <input type="text" name="location">, and I'd like to get in touch with you for the following purpose:</p>
<p><textarea name="message" rows="10" ></textarea></p>
<p>By the way, my email address is <input type="text" name="email" id="email" placeholder="john@doe.com">, and I can prove I'm not a robot because I know the sky is <input type="text" name="code" placeholder="Red, green or blue?">.</p>
<p title="Send this message."><input type="submit" id="submit" value="Take care."></p>
</form>
And this is the script, in an external file called contact.php: Code: <?php
$name = check_input($_REQUEST['name'], "Please enter your name.") ;
$location = check_input($_REQUEST['location']) ;
$message = check_input($_REQUEST['message'], "Please write a message.") ;
$email = check_input($_REQUEST['email'], "Please enter a valid email address.") ;
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email)) {die("E-mail address not valid");}
if (strtolower($_POST['code']) != 'blue') {die('You are definitely a robot.');}
$mail_status = mail( "my@email.com", "Hey!", "Hello,\n\n$message\n\nRegards,\n\n$name\n$location", "From: $email $name" );
function check_input($data, $problem='')
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
if ($problem && strlen($data) == 0)
{
show_error($problem);
}
return $data;
}
function show_error($myError)
{
?>
<html>
<body>
<b>Please correct the following error:</b><br />
<?php echo $myError; ?>
</body>
</html>
<?php
exit();
}
if ($mail_status) { ?>
<script language="javascript" type="text/javascript">
alert('Thank you for the message. I will try to respond as soon as I can.');
window.location = '/about';
</script>
<?php
}
else { ?>
<script language="javascript" type="text/javascript">
alert('There was an error. Please try again in a few minutes, or send the message directly to aalejandro@bitsland.com.');
window.location = '/about';
</script>
<?php
}
?>
So what it does is this: if everything's OK, it sends an email with "Hey!" as the subject, "[name]" as the sender, "Hello, [message]. Regards, [name], [location]" as the body, and a popup saying the message was delivered appears. If something fails, it outputs the error in a new address, so the user will have to go back to the form and correct the error. What I actually want to happen is this: if everything's OK, a <p> which was hidden beneath the form appears saying the message was delivered, or, alternatively, make the submit button gray out and confirm the message was delivered. I found a script to make this happen, but with "Please wait...", so the user can't resubmit the form. If there's an error, I'd like another <p> which was hidden to appear with the specific error, so there'd be many <p>'s hidden with different IDs. If possible, I'd also like to change the CSS style of the input field, specifically changing the border color to red, so it'd be a change in class for the particular field. -- So in essence, I want the errors and the success messages to output in the same page as the form (without refresh), and a change of class in the input fields that have an error. It'd be great if the submit button could be disabled until all fields are filled correctly, but I don't know if this is possible. Thanks in advance, and please let me know if it'll be possible. :) I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes. I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return. html form: Code: <form id="f1" name="form1" onsubmit="validate_form(this); return false;" action="register" method="post">

could anyone tell me how to do this? i don't know anything about javascript, but it is the most elegant way to validate a form. i have 2 questions asked in a form (name=questions). First question are radio buttons with 3 answers (name=answer). Second is a questions with a numeric value as answer with max 10 characters (name=questionb). Could anyone tell me where to start? Thanks, Walter Hi Guys, I have trying to validate my form using JavaScript. On blur of the a text box I am calling a function in JavaScript which checks if the text box is empty or not.... If the text box is empty it display an appropriate error message. The issue I am facing is that, for the first time if any user does not enter any value in the text box, the JS function is invoked and an appropriate error message is displayed.... So when the user tried to enter a value in the text box, a drop down list appear from the past forms data. (The drop down value appear because the user has already filled in the form in the past. Hence the Browser remember the data filed in, and displays it as a drop down list.) This allows the user to select any values from the drop down list to fill in the box.* After the user has selected the appropriate value from the drop down and takes its mouse cursor and navigates to another text box in the form, the first error message does not disappear. The form does not recognize that the value filed has already been filled in the first filed.* If the user actually types into the field it recognizes that the text box has a filed is filled. Please may I know how to solve this issue. I have problem with my javascript form validation... Validation works only on last question and I can't understand why it doesn't work on other questions..

Hi i need help with an assignment that validates forms using javascript. Using my instructors example as a guide, i wrote this if you click submit on the example it properly returns false and displays an error message, in my assignment it does nothing but submit to the echo while im trying to get an error message. The assignment is unfinished but i wanted to test out the first bit of code and its not working. Hello, I am using the following javascript to validate a text field on my site: Code: function checkExpire(form)
{
// regular expression to match required date format
re = /^\d{1,2}\/\d{1,2}\/\d{4}$/;
if(form.txtExpire.value != '' && !form.txtExpire.value.match(re)) {
alert("Invalid date format: " + form.txtExpire.value);
form.txtExpire.focus();
return false;
}
return true;
}
The above code works fine for the following situations: The default value of the field is: __/__/____ The JavaScript code above will not accept that for a field value. If a user inputs the following for a date 5_/7_/11__ for May 7th, 2011 the JavaScript will not accept the format it must be entered as: 05/07/2011 (in order to clear the validation)... NOW HERE IS WHAT I NEED THE JAVASCRIPT TO DO: 1) It needs to accept __/__/____ as a value that can be inserted into the database 2) still retains the code above so 5_/7_/11__ is not an acceptable date but 05/07/2011 will work just fine 3) Now... the default value of the text field in Internet Explorer is __/__/____ but the value is blank in Mozilla Firefox so in an instance where the text field is completely blank I need the JavaScript to assign the value '__/__/____' ... SO FAR: I did at one point get both the validation working so it worked for rules 1 and 2 mentioned above but I completely destroyed it while trying to integrate rule 3 into the functionality. So I know this can be accomplished with a series of if / else statements as well as assigning a value to a form object to handle rule# 3 ... I am just a novice getting ready to turn intermediate in JavaScript so any help, guidance, reference or example / sample code you could give me would be much appreciated. Thank your for your assitance and I hope you are all doing well. Cordially, aRK Hi there! Could somebody please help me understand why this javascript isn't executing? I've been stuck with it for days and have researched the problem to death to no avail. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

if(number.value == null) {
result = false;
break;
}
}
if(result == false) {
alert("Please fill in all the fields");
return result;
}
return result;
}
</script>
