How to split string of input tag HTML?

When a user enters the below link in an input tag, I just want the last part of the string, in order to minimize input mistakes - the two input fields generate a new link that the user can copy and use.
name:id:5icOoE6VgqFKohjWWNp0Ac (I just want the last '5icOoE6VgqFKohjWWNp0Ac' part)
Can anyone help me with amending the below to achieve this?
function generateFullName() {
document.getElementById('txtFullName').value = ('https://nlproducts.nl/item/') + document.getElementById('fName').value + ('?context=') + document.getElementById('lName').value;
}
Enter a product ID:
<input type="text" id="fName" placeholder='0A5gdlrpAuQqZ2iFgnqBFW' />
Enter a user ID:
<input type="text" id="lName" oninput="generateFullName()" placeholder='37i9dQZF1DXcBWIGoYBM5M'/><br/></p>
Tada! This would be the link for your campaign:
<input type="text" id="txtFullName" name="txtFullName" />

Here's a JavaScript function that takes a string as input, and formats it to only keep the last part after the last colon (if it contains a colon):
function parseColon(txt) {
return txt.split(":").slice(-1).pop();
}
Eg. parseColon("a:b:c") would return "c"
You can validate your inputs with:
function isValidInput(txt) {
numberOfColons = txt.split(":").length - 1;
if (txt.length == 32 && numberOfColons == 2)
return true
return false
}
In your code you can use these two functions to check & parse lName and fName like this:
function generateFullName() {
var lName_val = document.getElementById('lName').value;
var fName_val = document.getElementById('fName').value;
//fill in link in the output if fName and lName are valid inputs
if(isValidInput(fName_val) && isValidInput(lName_val))
document.getElementById('txtFullName').value = ('https://nlproducts.nl/item/') + parseColon(fName_val) + ('?context=') + parseColon(lName_val);
// otherwise, clear the output field
else
document.getElementById('txtFullName').value = "";
}
function parseColon(txt) {
// return the part after the last colon
return txt.split(":").slice(-1).pop();
}
function isValidInput(txt) {
numberOfColons = txt.split(":").length - 1;
if (txt.length == 38 && numberOfColons == 2)
return true
return false
}
Enter a product ID:<br>
<input type="text" id="fName" oninput="generateFullName()" placeholder='0A5gdlrpAuQqZ2iFgnqBFW' size="50"/><br/>
Enter a user ID:<br>
<input type="text" id="lName" oninput="generateFullName()" placeholder='37i9dQZF1DXcBWIGoYBM5M' size="50"/><br/><br/>
Tada! This would be the link for your campaign:<br>
<input type="text" id="txtFullName" name="txtFullName" size="50"/>

Javascript Phone Number Validation- error message erace

Goal:
Phone number must be entered in this format, 208-111-1111; otherwise it shows the error message.
What is the best way to show the error message when the user entered in the correct format but if the user re-entered in the correct format, the error message will disappear.
JS
phoneNumber = document.getElementById("phone");
var result = phoneNumber.toString().match(/^\d{3}-\d{3}-\d{4}$/);
function validatePhone(){
if (result == null)
{
error2.innerHTML = "The number is not in a correct format";
} else
{
error2.innerHTML = " ";
};
}
HTML
<p>Phone:</p>
<input type = "text" id="phone" name="phone" onChange="validatePhone()">
<br>
<span id="error2" ></span>

function validatePhone() {
phoneNumber = document.getElementById("phone");
var result = phoneNumber.value.match(/^(\d{3}-\d{3}-\d{4})?$/);
if (result == null) {
error2.innerHTML = "The number is not in a correct format";
} else {
error2.innerHTML = " ";
};
}
<p>Phone:</p>
<input type="text" id="phone" name="phone" oninput="validatePhone()">
<br>
<span id="error2"></span>

The problem is with the phoneNumber.toString() call.
Calling toString() on a DOM input element does not return the value of the user input. toString() is intended to provide a string representation of the object it is called on, not retrieve a value held by the object.
phoneNumber.value will return the value you are looking for.

if contact number is both empty and does not have 11 digits

id like my "Invalid contact number" to show if the text field is empty or if it does not contain 11 digits (if the text field has content)
HTML:
<label id="number_label">
<b>Contact Number</b>
</label>
<input type="text" placeholder="Contact Number" class="form-control" id="contact" name="contact">
Javascript:
var contact = document.getElementById("contact").value;
if (!contact || (contact.val().length >=12 || contact.val().length <=10) ) {
document.getElementById("number_label").innerHTML = "<span style='color: red;'>Invalid contact number (must contain 11 digits)</span>";
} else {
document.getElementById("number_label").innerHTML = "Contact Number";
}
My "number_label" id in the if statement should change text and display the error.

It isn't working
You're calling .val() on contact (a String) which is no good. .val() is a jQuery method, and is meant to be called on the element itself.
the form just loads the "Invalid contact number" and reloads the page going back to the beginning
If you're trying to restrict a form from posting, make sure any path in your function that should restrict this has a return false.
var label = document.getElementById("number_label");
function validate() {
var contact = document.getElementById("contact").value;
if (!contact || contact.length !== 11) {
label.innerHTML = "<span style='color: red;'>Invalid contact number (must contain 11 digits)</span>";
return false;
} else {
label.innerHTML = "<b>Contact Number</b>";
}
}
<label id="number_label">
<b>Contact Number</b>
</label>
<input type="text" placeholder="Contact Number" class="form-control" id="contact" name="contact">
<button onclick="validate()">Validate</button>

Your code has some errors. val() is not a function of the element.
if (!contact || (contact.**val()**.length >=12 || contact.**val()**.length <=10) ) {

Multiphase Form (wizard) show all information before submit

I create a multiphase form (wizards from) and I want to show in the last step all Information in input text (you can modify it) before validate
I try a lot but without any result, how can I do it ?
My code
var fname, lname, age;
function _(x) {
return document.getElementById(x);
}
function processPhase1(){
fname = _("firstname").value;
lname = _("lastname").value;
if(fname.length > 2 && lname.length > 2){
_("phase1").style.display = "none";
_("phase2").style.display = "block";
}
else {alert("Please Enter All Information");}
}
function processPhase2(){
age = _("age").value;
if(age.length >= 1){
_("phase2").style.display = "none";
_("show_info").style.display = "block";
}
else {alert("Please Enter All Information");}
}
<body>
<div id="phase1">
First Name : <input id="firstname" name="firstname"><br>
Last Name : <input id="lastname" name="lastname"><br>
<button onclick="processPhase1()">Next</button>
</div>
<div id="phase2">
Age : <input id="age" name="age"><br>
<button onclick="processPhase2()">Next</button>
</div>
<div id="show_info">
First Name : <input id="firstname" name="firstname" value = ""><br>
Last Name : <input id="lastname" name="lastname" value = ""><br>
Age : <input id="age" name="age" value = ""><br>
<button onclick="submit()">submit</button>
</div>
I try this but it's just for showing Information, but you can't modify it, I need to show it in input text
function processPhase2(){
age = _("age").value;
if(age.length >= 1){
_("phase2").style.display = "none";
_("show_info").style.display = "block";
_("display_fname").innerHTML = fname;
_("display_lname").innerHTML = lname;
_("display_age").innerHTML = age;
}
else {alert("Please Enter All Information");}
}
<div id="show_info">
First Name : <span id="display_fname"></span><br>
Last Name : <span id="display_lname"></span><br>
Age : <span id="display_age"></span><br>
<button onclick="submit()">submit</button>
</div>

I would have done this completely different, but this is how you would do it based on what you've already written. When you click the next button in each function, you want to grab that value of (fname, lname, or age) and set the value of that to the value of the last set of inputs. I've altered your code a bit and made you a JS BIN http://jsbin.com/sopikuzuri/edit?html,output
In simple terms
Each time you call a new phase function (processPhase1), you want to grab the values of what the user just entered.
Then, you want to set those values to the proper <input />
So, the simplest example I can give is this:
Below, the user will enter some data into the field. When they click the submit phase 1 button we will grab the value of what they just entered and set that value to the last input (for them to see/edit)
<input type="text" id="firstName"/>
<button id="submit">Submit Phase 1</button>
<input type="text" id="displayInput"/>
<script>
$("#submit").click(function() {
// getting the value of what the user typed in
var fname = $("#firstName").value;
// setting the value of the final box to the var above
$("#displayInput").val(fname);
});
</script>

How do I print user input with the first letter of each word capitalized?

I am working with a form and would like to print the user's input with the first letter of each word capitalized no matter how they type it in. For example, I want the user's "ronALd SmItH" to print as Rondald Smith. I would also like to do this for the address and city. I have read all of the similar questions and answers on here and they are not working for me. I am not sure if I am putting my code in the wrong place or what I'm doing wrong.
This is the code I am using:
function correctFormat(customer)
{
var first = customer.charAt(0).toUpperCase();
var rest = customer.substring(1).toLowerCase();
return first + rest;
}
I have tried placing that in a variety of places within the whole document, I have tried renaming the string (eg. name, city, address). I have also read the others postings on here with what seems like the same question as this but none are working. I am not entering a string that I want capitalized. The user is entering their data into a form and I need it to print in an alert in the correct format. Here is the above code within the entire document. I am sorry it is so long but I am again, at a loss.

You can use regular expression, such as this:
function correctFormat(customer){
return customer.replace(/\b(.)(.*?)\b/g, function(){
return arguments[1].toUpperCase() + arguments[2].toLowerCase();
});
}

Your function only capitalizes the first letter of the string but not the first letter of each word. You can try splitting the string into separate words using string.split(' '):
function correctFormat(customer)
{
if (customer == null || customer.length == 0)
return customer;
var words = customer.split(/\s+/g);
for (var i = 0; i < words.length; ++i) {
var first = words[i].charAt(0).toUpperCase();
var rest = words[i].substring(1).toLowerCase();
words[i] = first + rest;
}
return words.join(' ');
}
I also noticed that you do not call correctFormat anywhere. You need to call the function in order for it to be executed. For example:
var customer = correctFormat(document.PizzaForm.customer.value);

As mentioned by #Wee You, you use customer for the first letter but use name for the rest letters. You have to call this function with user inputs and then update text in dom with the correct format.
function correctFormat(str)
{
var first = str.charAt(0).toUpperCase();
var rest = str.substring(1).toLowerCase();
return first + rest;
}

Here's a tiny example of the code you need:
Pass to the .replace() method every name part:
var PizzaForm = document.PizzaForm;
var customer = PizzaForm.customer;
function formatName() {
this.value = this.value.replace(/([^ \t]+)/g, function(_, str) {
var A = str.charAt(0).toUpperCase();
var bc = str.substring(1).toLowerCase();
return A + bc;
});
}
customer.addEventListener("input", formatName);
<form name="PizzaForm">
Name: <input name="customer" size="50" type="text">
</form>
the above will work also on Paste. Have fun
PS: instead of all that doClear(){ wall of code, why don't you reset your form by simply using: PizzaForm.reset();

Try this function
function correctFormat(customer)
{
var upperText = customer.toLowerCase();
var result = upperText.charAt(0).toUpperCase();
for(var i=1;i<upperText.length;i++)
if(upperText.charAt(i-1) == ' ')
result += upperText.charAt(i).toUpperCase();
else
result += upperText.charAt(i);
return result;
}
