JavaScript - Need Help Validating A Multi-field Form For An Educational Game
Hello,
I'm working on a cryptogram game for an educational site. The cryptogram will be displayed like scrabble tiles, and letter will have a corresponding text box. So for a five-letter word, there will be five scrabble tiles with five small text boxes beneath for students to fill in individual letters. At the end there will be a validate button that tells them if they have all the letters right or not. I found a reference to this solution in the forum: http://www.clickfind.com.au/javascri...tion/index.cfm. It looks to me like this will work but I can't figure out how to modify it to check for specific values. I've posted an example of my table below in case it's useful to a helpful person out there. I realize it's not much of a start. Thanks in advance for your help, ransomcat Code:
<form>
<table id="cryto_one" class="crypto" cols="15">
<tr>
<td><img src="tiles/20wide/4.gif" /></td> <td> </td> <td><img src="tiles/20wide/!.gif" /></td> <td><img src="tiles/20wide/3.gif" /></td>
</tr>
<tr>
<td><input name="four" type="text" class="crypto_letter" /></td> <td></td> <td><input name="exclam" type="text" class="crypto_letter" /></td> <td><input name="3" type="text" class="crypto_letter" /></td>
</tr>
</table>
<input type="submit" value="Submit" />
</form>
Similar TutorialsI am somewhat a noob at js/jquery so I wasn't sure exactly how to do this. Think I just need a push in the right direction. Basically I'm trying to validate a form (jquery validation) with a couple of conditionals based on a selection box. So I have: Code: <form id="info" class="validate">
<select id="select">
<option value="senior">Senior Citizen</option>
<option value="adult">Adult</option>
<option value="child">Child</option>
</select>
<input type="text" name="age" id="age" class="required" minlength="1" maxlength="3" title="age group">
</form>
I'm trying to validate that if the user has selected "Senior Citizen" then their age must be 65 or older (and validate the adult/child ages as well). I hope to get this all in ajax so it would be checking it live. Thanks for the help! Hi, I am trying to only allow a person to enter alpha characters in this field and if they try to enter a number a pop up box will tell them they can only enter alpha characters. Can this be done? Here is my code: How would you like us to address you? ("Dear Pat" Dear <input name="SALUT" type="text" id="address2" style="color: #000000; border-left: 0px solid #008000; border-right: 0px solid #254D78; border-top: 0px solid #008000; border-bottom: 2px solid #0033CC; background-color: #EBE1BE" tabindex="5" size="15" maxlength="50" onFocus="if(this.value=='SALUT')this.value='';"> Any help would be greatly appreciated. Thanks I managed to create the form that asks you to type in the information but I'm having some difficulty trying to figure out the alert to say "Thank you " after you have everything filled in and then hitting the button. my code is Code:

Help me. Thanks. Clement Osei. Hello, I have a form which asks for some user data and then submits this data and inserts into a mysql database. I wanted to know the best way to validate the form before the data is submittted to the action script. For example, checking form fields to see if they are empty and also making sure no special characters are inserted by the user. The code I have tried is: Code: function checkForm() {
var theForm = document.forms.feedback;
if (theForm.fname.value == "" || theForm.loc.value="" || theForm.com.value == "") {
alert("Please complete all of the form");
}
}
Working with this form: Code: <form id="feedback" name="feedback" action="php/phpcustom.php" method="POST">
<fieldset>
<legend>Gardenable.com Feedback</legend>
<p><label for="fname">Name:</label><input type="text" size="30" maxlength="40" id="fname" name="fname" /></p>
<p><label for="loc">Location:</label><input type="text" size="30" maxlength="40" id="loc" name="loc" /></p>
<p><label for="com">Comments:</label><textarea cols="40" rows="6" maxlength="300" id="com" name="com"></textarea></p>
<p><input type="submit" name="send" id="submitbutton" value="Submit" onclick="checkForm()" /><input type="reset" name="reset" value="Reset" /></p>
</fieldset>
</form>
I've added this function to the onclick attribute of the submit input button but it is just submitting the data and not executing. Just wondering if anyone could please explain how to stop the execution of the data being submitted and check the form before doing so. If not could you possibly advise any good sites/links for me to browse to achieve this. regards, LC. Hi, I'm a student learning web design and having a problem with some javascript code, I'm validating a text area, i dont have a problem limiting how many characters can be typed in the textarea, but I cant get it to give an error if there is no text in the text area. In the code below the validateMes() function is not working, the other functions work fine Javascript code: Code:
function validateLimit(fld){
var error ="";
if(fld.value.length > 300){
error = "Cannot exceed 300 characters.\n"
fld.style.background = 'Yellow';
}else{
fld.style.background = 'White';
}
return error;
}
function validateMes(fld) { //this function not working
var error = "";
if (fld.value.length == 0) {
fld.style.background = 'Yellow';
error = "The Message field has not been filled in.\n"
} else {
fld.style.background = 'White';
}
return error;
}
function validateFormOnSubmit(form1) { //master validating function
var reason = "";
reason += validateLimit(form1.mess);
reason += validateMes(form1.mess);
if (reason != "") {
alert("Some fields need correction:\n" + reason);
return false;
}else{
alert("Message has been submitted");
return true;
}
}
Html form code: Code:
<form name="form1" id="form1" onsubmit="return validateFormOnSubmit(this)" >
<div class="box">
<h1>CONTACT FORM :</h1>
<label>
<span>Full name</span>
<input type="text" class="input_text" name="name" id="name" value=""/>

<input type="text" class="input_text" name="subject" id="subject" value=""/>
</label>
<label>
<span>Message</span>
<textarea class="message" name="mess" id="mess" ></textarea> <span>*Message limited to 300 characters</span>
<input type="submit" class="button" value="Submit Form" />

I can't see what I'm doing wrong, would really appreciate some help Thanks hi im new to scripting so apologies if this is a basic question. I have a form which has javascript validation which triggers hidden divs if certain input boxes are left blank. I have it working with text fields and text areas, but im having trouble with a drop down menu. This is the code for my drop down: Code: <select name="department" size="1" id="department"> <option value="" selected>Please select</option> <option value="1">Personal Injury</option> <option value="2">ULR & Credit Hire</option> <option value="3">Consumer Credit</option> <option value="4">Health & Safety</option> <option value="5">Property</option> </select> And this is the code currently for the Javascript validating: Code: if(department.selectedIndex == 0){
var error = true;
$('#department_error').fadeIn(500);
}else{
$('#department_error').fadeOut(500);
If i leave the drop down on the 'Please Select' value, the error message should show, but at the moment it doesnt show up. I have a feeling the syntax is wrong in the javascript? Any help very much appreciated Thanks hello everyone Im new to javascript as well as to this forum, Im coming here for first class help that I can only get from skilled programmers like you. I have a html form that uses javascript for validation, this is an assignment that consists of a form that sells hard drives from three different manufacturers, more specifically the part im stuck on is where if a manufacturer hoes have a number in the number of drives textbox, javascript needs to check to see that one of the radio buttons in that row is checked, if no radio button is checked an alert is displayed, however when I do select a radio button I still get the alert I used a "if...else if...else" construction but my logic is not well structured and thereby I get those problems, I have included the code down below if anyone is interested in helping a newbie out, thanks Code: <html>

I've been searching for how to do this, what seems simple, task. I have a form with multiple inputs and I want to be able to save them onchange, using the html5 function localStorage. Does anybody have an idea how I could go about doing this? It seems simple but I'm not very familiar with coding. Any help is appreciated! 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. Could someone please explain what I am doing wrong? here is my code so far... Note: just for testing purposes I've put return false on everything so it displays a message when everythings ok. Code: ....
<script type="text/javascript">
window.onload = function() {
document.forms[0].username.focus();
}
function validate(form)
{
var form = document.getElementById("reg");
var e = document.getElementById("error");
e.style.background = "red";
for(var i = 0; i < form.elements.length; i++)
{
var el = form.elements[i];
if(el.type == "text" || el.type == "password")
{
if(el.value == "")
{
e.innerHTML = "Please fill in all fields!";
el.style.border = "1px solid red";
el.focus();
return false;
} else {
el.style.border = "1px solid green";
return false;
}
}
}
var un = form.username;
un.value = un.value.replace(/^\s+|\s+$/g,"");
if((un.value.length < 3)|| (/[^a-z0-9\_]/gi.test(un.value)))
{
e.innerHTML = "Only letters,numbers and the underscore are allowed (no spaces) - 3-16 characters";
un.focus();
return false;
}
var pw = form.password;
pw.value = pw.value.replace(/^\s+|\s+$/g,"");
if((pw.value.length < 3) || (/[^a-z0-9]/gi.test(pw.value)))
{
e.innerHTML = "Only letters and numbers are allowed (no spaces) - 3-16 characters";
pw.focus();
return false;
}
e.innerHTML = "You filled in all the fields, well done!";
e.style.background = "green";
return false;
}

What am I? the answer is: Your Breath. (This is where the JAVASCRIPT comes in) Lets say they guess a rock, have a pop up say: Wrong Answer. Please try again. Lets say they guess Your breath -OR- Breath, have a pop up say: Correct! I want a text field where you can enter your answer, and if they choose ANYTHING but the 2 correct answers above, it will display please try again. Can anyone code this please? Thanks for reading. Ok so i want to work on an EASY basic game. As simple as Guess what number... But there are some twist... Ok So here is my example... (HTML, i know this.)I'm Guessing a number 1-99. What is it? (java) Lets say its 66 and they guess 53, have the text rusult be in a pop up window be: Too low! (java) Lets say they guess 78, have the text rusult be in a pop up window be: Too high! (java) Lets say they guess 100+, have the text rusult be in a pop up window be: Out of range! (java)But lets say they guess 66, have a text result be in a pop up window be: You've won! (java) I want a text field where you can enter your answer, and it will do the actions above. Can anyone code this? Thanks for reading! How can I add a form field value to a url.

I need to learn how to clear form fields when a user clicks on them. Here is the site in question: http://www.yourvancouvermortgagebroker.ca/apply They used to work, but then I changed the field value and now it doesn't work on some of the fields (whichever ones I changed). Here is a link to the .js file: http://www.yourvancouvermortgagebroker.ca/js/apply.js Hi! I use the :: Form field Progress Bar from DynamicDrive: Form field Progress Bar Now I trided to change the text when the textarea is full "Limit:100%" to "Your max. characters is reached" I trided it but with no luck. This is the main code.. Code: <script type="text/JavaScript">
function textCounter1(field,counter,maxlimit,linecounter) {
// text width//
var fieldWidth = 137;
var charcnt = field.value.length;
// trim the extra text
if (charcnt > maxlimit) {
field.value = field.value.substring(0, maxlimit);
}
else {
// progress bar percentage
var percentage = parseInt(100 - (( maxlimit - charcnt) * 100)/maxlimit) ;
document.getElementById(counter).style.width = parseInt((fieldWidth*percentage)/100)+"px";

The reason for this is that the form has add buttons to add another field or fields for the purpose of entering another email address, etc., to send invitations and do other things. The problem that I am running into is how to access the individual fields in an array of fields inside javascript to do form validation. So if I have an email address field name emailAddress[], and using the add button, the user of my site adds 3 other copies of the emailAddress[] field, I want to then do form validation onSubmit to ensure those email address are valid using standard procedures. However, inside the javascript code, how do I access the individual fields that make up emailAddress[]? I just cannot find anywhere online the proper way to get at these values. If anyone can help me, I would greatly appreciate it. Happy Holidays |
