My find matches function does not seem to be working.
I want to get an array ([]) element by id and do comparisons with it.
The function is supposed to go into the array and generate a random person, then display the match in the text area "showmatches".
I am not sure if the random person is being generated nor if the criteria are being matched in the comparison.

Do these steps. First you have two window.onload = () (As you are not using addEventListener only one event will be attached).
Steps:
Keep everything intact, just remove the window.onload from both places. Keep all code inside load intact.
Move the entire code block just to the bottom of the html above closing tag. (Doing so, will make window.onload redundant.)
Put console.log() in the click handler and see if it's working (it will)
Let us know.
NOTE: On other hand there are better way to code this, for e.g wait for DOMContentLoaded for attaching event etc., but it's too big to discuss here. First make this work, then we can recommend better approaches.

I'm not sure what I'm doing wrong here. It says that my variables are not defined, but I did that at the top of the js file. I think all my logic is correct, but something is not right somewhere I haven't been able to figure out what it is. I'm just adding more text here so it will let me edit this question with updated coded. Delete this last bit as needed. Thanks.
function calculate() {
document.getElementById("cost").innerHTML = "Cost: "
var cost = Number(document.getElementById("type").value);
var years = Number(document.getElementById("years").value);
if (years > 1) {
var discount = cost * 0.20
cost -= discount ; // 20%
document.getElementById("cost").innerHTML += cost;
} else {
document.getElementById("cost").innerHTML += cost;
}
return false;
}
I made two changes and it runs without error:
var cost = parseInt(document.getElementById("cost).value);
Should have another " after cost, and:
if (type && type.value && years && (years > 0)) {
should be years.value > 0
Then change the switch to:
switch (type.value) {
and the cases to:
case 'basic':
case 'premium':
etc.
function calculate() {
// Be strict:
'use strict';
// Variable to store the total cost:
var cost;
// Get a reference to the form elements:
var type = document.getElementById('type');
var years = document.getElementById('years');
// TODO Convert the year to a number:
// Check for valid data:
if (type && type.value && years && (years.value > 0)) {
// TODO Add a switch statement to determine the base cost using the value of "type"
switch (type.value) {
case 'basic':
window.console.log("Basic - $10.00");
break;
case 'premium':
window.console.log("Premium - $15.00");
break;
case 'gold':
window.console.log("Gold - $20.00");
break;
case 'platinum':
window.console.log("Platinum - $25.00");
}
// TODO Update cost to factor in the number of years:
var cost = parseInt(document.getElementById("cost").value);
// Discount multiple years:
if (years > 1) {
cost -= (cost*20); // 20%
}
// TODO update the value property of 'costElement' to the calculated cost
var costElement = document.getElementById('cost');
} else { // Show an error:
document.getElementById('cost').value = 'Please enter valid values.';
}
// Return false to prevent submission:
return false;
}
function init() {
'use strict';
// call a function named calculate() when form submitted
document.getElementById('theForm').onsubmit = calculate;

On the 82 line of my JavaScript I have "document.getElementById("errors").innerHTML = errMsg;" this code and I was wondering how to implement it into my HTML page so when the validation isn't correct the error message will be displayed in the correct place such as when someone is younger then 15 the error message will be displayed next to date of birth. At the moment I have my errors appearing in an alert but I'd like them to appear on the web page. I also when to know if my "storeForm" and "prefillForm" functions are correct because I tried to test them and it doesn't seem to work. How do I go about fixing these?

you may create a generic function like that :
function show_error(element, message) {
element.parentElement.innerHTML += "<span class='error'>" + message + "</span>";
}
//call the function
show_error(document.getElementById('street'), 'error message');
.error {
color: red;
}
<p><label for="street">*Street Address:</label>
<input type="text" name="street" id="street" maxlength="40" size="30" required="required" /></p>
<p><label for="suburb">*Suburb/town:</label>
<input type="text" name="suburb" id="suburb" maxlength="40" size="20" required="required" /></p>
Then you can add another function to remove this error.
You can do the below to update when there is an error. I have added a small code to demonstrate.
$(document).ready(function() {
$("#btn").click(function() {
validate();
});
});

How to Enable/Disable input field based on a dropdown selection. and also I should take the user data in JSP based on the selection.
<form action="../jsp/findActorbyChar.jsp">
<h3>Search by:
<select name ="nameField"> </h3>
<option> Only FirstName </option>
<option> Only LastName </option>
<option> Or </option>
<option> And </option>
</select>
<br><br>
First Name <input type="text" name="firstName"/>
Last Name <input type="text" name="lastName"/>
<br><br>
<input type="submit"/>
<input type="reset"/>
Modified Html as shown below:
<h3>Search by:</h3>
<select name ="nameField" id="nameField">
<option>Only FirstName</option>
<option>Only LastName</option>
<option>Or</option>
<option>And</option>
</select>
<br><br>
First Name <input type="text" name="firstName" id="firstNameInput"/>
Last Name <input type="text" name="lastName" id="lastNameInput" />
<br><br>
<input type="submit"/>
<input type="reset"/>
Javascript code:
var nameField = document.getElementById("nameField");
var firstNameInput = document.getElementById("firstNameInput");
var lastNameInput = document.getElementById("lastNameInput");
nameField.addEventListener("change", function(){
//Update this to your logic...
if(nameField.value === "And"){
firstNameInput.disabled = true;
lastNameInput.disabled = true;
}
});
But I think it would be easier if using JQuery to handle DOM update.
Give your menu an id and then you can access the selected index with menu.options.selectedIndex. From there, you can add an on change handler to the menu and use switch cases to set the disabled attribute of the menu.
<h3>Search by:
<select id="menu" name ="nameField"> </h3>
<option> Only FirstName </option>
<option> Only LastName </option>
<option> Or </option>
<option> And </option>
</select>
<br><br>
First Name <input id="first" type="text" name="firstName"/>
Last Name <input id="last" type="text" name="lastName"/>
<br><br>
<input type="submit"/>
<input type="reset"/>
<script type="text/javascript">
var menu = document.getElementById('menu');
var first = document.getElementById('first');
var last = document.getElementById('last');
menu.onchange = function(){
var enableFirst = false, enableLast = false;
switch(menu.options.selectedIndex){
case 0:
enableFirst = true;
enableLast = false;
break;
case 1:
enableFirst = false;
enableLast = true;
break;
case 2:
/*not sure which results you want here*/
break;
case 3:
/*not sure which results you want here*/
break;
default:
break;
}
first.disabled = !enableFirst;
last.disabled = !enableLast;
}
</script>
My code: still all the input fields are enabled
enter code here
<script src="script.js">
var nameField = document.getElementById("nameField");
var firstNameInput = document.getElementById("firstNameInput");
var lastNameInput = document.getElementById("lastNameInput");
nameField.addEventListener("change", function(){
//Update this to your logic...
<script src="script.js">
var nameField = document.getElementById("nameField");
var firstNameInput = document.getElementById("firstNameInput");
var lastNameInput = document.getElementById("lastNameInput");
nameField.addEventListener("change", function(){
//Update this to your logic...
if(nameField.value === "And"){
firstNameInput.disabled = true;
lastNameInput.disabled = true;
}
else if(nameField.value === "firstNameInput"){
firstNameInput.disabled = false;
lastNameInput.disabled = true;
}
else if(nameField.value === "lastNameInput"){
firstNameInput.disabled = true;
lastNameInput.disabled = false;
}
elseif(nameField.value === "lastNameInput"){
firstNameInput.disabled = true;
lastNameInput.disabled = true;
}
});
</script>
I need to do a Javascript verification of the fields. I need to know how to make for each span of every label how to make it display the write message.
At the moment the html code is:
<form method="post" id="contactForm" onclick="return main();">
<fieldset>
<div class="subscribe">
<label for="firstName">First name:</label>
<input type="text" name="firstName" id="firstName"/>
<span id="fnameMessage" class="infomessage">
Your first name should contain at least 2 alpha characters.
</span>
</div>
<div class="subscribe">
<label for="lastName">Last name:</label>
<input type="text" name="lastName" id="lastName"/>
<span id="lnameMessage" class="infomessage">
Your last name should contain at least 2 alpha characters.
</span>
</div>
<div class="subscribe">
<label for="title">Title:</label>
<select name="title" id="title">
<option value="1"> Mr. </option>
<option value="2"> Ms. </option>
<option value="3"> Mrs. </option>
<option value="4"> Miss. </option>
<option value="5"> Master. </option>
</select>
</div>
<div class="subscribe">
<label for="hNumber">Health Authority Number:</label>
<input type="text" name="number" id="hNumber"/>
<span id="hanMessage" class="infomessage">
Your ZHA number should be in the form of 6 digit integer prefixed wit the letters ZHA.
</span>
</div>
<div class="subscribe">
<label for="email">Email address: </label>
<input type="email" name="email" id="email"/>
<span id="emailMessage" class="infomessage">
Your email address should be as example: example#difexample.com.
</span>
</div>
<div class="subscribe">
<label for="phoneNumber">Telephone number:</label>
<input type="text" name="phoneNumber" id="phoneNumber"/>
<span id="phoneMessage" class="infomessage">
Your phone number should contain 11 numeric characters.
</span>
</div>
<div class="button">
<input id="btn1" type="submit" value="Submit" />
</div>
</fieldsed>
</form>
The javascript code that I've done it's:
function main() {
document.getElementById("contactForm").onsubmit = validateAll,
document.getElementById("firstName").onblur = validateName,
document.getElementById("lastName").onblur = validateName,
document.getElementById("phoneNumber").onblur = validatePhone;
}
function validateName() {
var test1 = fieldEmpty(this);
var test2 = fieldLength(this,2,50);
var test3 = fieldCharacters(this, "A");
var result = test1&&test2&&test3;
return result;
}
function validatePhone() {
var test1 = fieldEmpty(this);
var test2 = fieldLength(this,11,11);
var test3 = fieldCharacters(this,"N");
var result = test1&&test2&&test3;
return result;
}
function fieldEmpty(id) {
var valid = true;
if (id.value == "") {
valid = false;
alert("Field Empty");
}
return valid;
}
function fieldLength(id,min,max) {
var valid = true;
var lng = id.value.length;
if (lng < min || lng > max) {
valid = false;
alert("Field Length");
}
return valid;
}
function fieldCharacters(id,character) {
var letters = /[a-zA-Z]/;
var numbers = /[0-9]/;
var patternTest;
var valid = true;
if(character == "N") {
patternTest = numbers;
}
else if(character == "A") {
patternTest = letters;
}
valid = patternTest.test(id.value);
if (!valid) {
alert("Pattern Fail");
}
return valid;
}
function validateField() {
var noErrors = true;
// var input = document.getElementById(this);
if(this.value.length<2) {
noErrors = false;
alert("You need to input more than 1 character in " + this.id);
}
if(noErrors==false) {
var temp = document.getElementById(this.id + "firstnamemessage");
temp.className = "infomessage";
}
}
function validateAll() {
return false;
}
window.onload = main();
