Answer 1

Use this code:

You'll need to change the line: splitFullName("firstName","lastName","fullName"); and make sure it includes the right field IDs from your form.

function splitFullName(a,b,c){
    String.prototype.capitalize = function(){
        return this.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
    };
    document.getElementById(c).oninput=function(){
        fullName = document.getElementById(c).value;
        if((fullName.match(/ /g) || []).length ===0 || fullName.substring(fullName.indexOf(" ")+1,fullName.length) === ""){
            first = fullName.capitalize();;
            last = "null";
        }else if(fullName.substring(0,fullName.indexOf(" ")).indexOf(".")>-1){
            first = fullName.substring(0,fullName.indexOf(" ")).capitalize() + " " + fullName.substring(fullName.indexOf(" ")+1,fullName.length).substring(0,fullName.substring(fullName.indexOf(" ")+1,fullName.length).indexOf(" ")).capitalize();
            last = fullName.substring(first.length +1,fullName.length).capitalize();
        }else{
            first = fullName.substring(0,fullName.indexOf(" ")).capitalize();
            last = fullName.substring(fullName.indexOf(" ")+1,fullName.length).capitalize();
        }
        document.getElementById(a).value = first;
        document.getElementById(b).value = last;
    };
    //Initial Values
    if(document.getElementById(c).value.length === 0){
        first = document.getElementById(a).value.capitalize();
        last = document.getElementById(b).value.capitalize();
        fullName =  first + " " + last ;
        console.log(fullName);
        document.getElementById(c).value = fullName;
    }
}

//Replace the ID's below with your form's field ID's
splitFullName("firstName","lastName","fullName");
