How to print user input with the first letter of each capitalized word?
I am working with a form and want to print user input with the first letter of each word, capitalized, no matter how they print it. For example, I want the user "ronALd SmItH" to be typed as Rondald Smith. I would also like to do this by address and city. I have read all similar questions and answers here and they don't work for me. I am not sure if I am putting my code in the wrong place or what I am 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 tried to put this in different places within the whole document, I tried to rename the string (e.g. name, city, address). I also read other posts here with what looks like the same question as on this one, but none seem to work. I am not entering the string I want in all caps. The user enters their data into the form and I need it to print in the alert in the correct format. Here is the above code throughout the document. I'm sorry it took so long, but again, I'm at a loss.

Your function only uses the first letter of the string, but not the first letter of each word. You can try splitting the string into individual 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 don't call correctFormat
anywhere. You need to call the function for it to execute. For example:
var customer = correctFormat(document.PizzaForm.customer.value);

As @Wee You mentioned, you use customer
for the first letter, but for the rest of the letters use name
. You have to call this function with custom inputs and then update the text in the 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: Go to the method .replace()
for each part of the name:
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>
above will work on Paste too. Enjoy
PS: instead of all this doClear(){
wall of code, why don't you reset your form just 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;
}
