Return multiple functions

Question

I am new to javascript, so I apologize if this is all totally wrong, but I'm trying to validate a form right now, and I have the simple functions for testing. I want the function validateForm() to return all three of the functions checkName(), checkEmail, and checkMessage(). The way I have the validateForm() function, it only runs the checkName() function. Any ideas?

function checkName(){

    var name=document.forms["contactForm"]["Name"].value;

    if(name==null || name==""){
        $("input#name").css("border-color", "#ff0000");
        $("input#name").attr("placeholder","Your name is required");
        return false;    
    }    
    else {
        $("input#name").css("border-color", "#00a8ff");
        $("input#name").attr("placeholder","");
        return true;
    }    
}

function checkEmail(){

    var email=document.forms["contactForm"]["Email"].value;

    if(email==null || email==""){
        $("input#email").css("border-color", "#ff0000");
        $("input#email").attr("placeholder","Your email is required");
        return false;    
    }    
    else {
        $("input#email").css("border-color", "#00a8ff");
        $("input#email").attr("placeholder","");
            return true;
        }
}

function checkMessage(){

    var message=document.forms["contactForm"]["Message"].value;

    if(message==null || message==""){
        $("textarea#message").css("border-color", "#ff0000");
        $("textarea#message").attr("placeholder","Your message is required");
        return false;    
    }    
    else {
        $("textarea#message").css("border-color", "#00a8ff");
        $("textarea#message").attr("placeholder","");
        return true;
    }
}

function validateForm(){

    return checkName() && checkEmail() && checkMessage();

}

Operator && executes left operand (checkName in your case), and, if it is false, immediately returns false without executing right operand. So, you need to manually execute each of your function and only then connect them via &&.

function validateForm(){
    var a = checkName();
    var b = checkEmail();
    var c = checkMessage();
    return a && b && c;
}
