JavaScript - Capitalize each word in a sentence

Question

I am trying to capitalize each word in a sentence in JavaScript. When ran I get an Uncaught TypeError saying myArray.substr is not a function.

function cap() {
    var myString, myArray, first, last, up, low;
    myString = document.getElementById("textbox").value;
    myArray = myString.split(" ");
    first = myArray.substr(0, 1);
    last = first.substr(1);
    up = myString.toUpperCase();
    low = myString.toLowerCase();

    document.getElementById("textbox").value = myString;

    return cap(" ");
}

Perhaps the split function is not returning an array in some circumstances — Grantly, Nov 11 '17 at 01:21

Check this answer here. This worked for me. I used what was mentioned,

return word[0].toUpperCase() + word.substr(1);

Try this

function toTitleCase()
    {
        var myString = document.getElementById("textbox").value;
        return myString.replace(/\w\S*/g, function(txt){return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();});
    }
