I grabbed the form from some random site because I'm only interested writing the javascript at the moment.

I am trying to check that a user has selected or entered text for all fields. I've made it a long if if-else but that can't be the best/most elegant/easiest solution. 

Leaving aside the radio button validation for now, what's the better way to check that the text fields, drop down, and checkboxes all have a value/input?

I'm teaching myself javascript so I'm open to being told the proper way and I'll research it and do it on my own, or updating my fiddle would be fine too. (Be gentle with me. I'm sure this code is janky.)

Any thoughts on this would be appreciated.

Fiddle: <https://jsfiddle.net/kiddigit/g0rur21a/>

```
document.getElementById("newForm").addEventListener("submit", enterForm);

function enterForm(event) {
    event.preventDefault();

    var dropdown = document.getElementById('dropDown');

    if (document.getElementById('fname').value === ''){ 
            document.getElementById('fname').focus(); 
            alert('Enter text.');
        } else if (document.getElementById('eMail').value === ''){
            document.getElementById('eMail').focus();
            alert('Enter text.');
            } else if  (document.getElementById('textArea').value === '') {
                document.getElementById('textArea').focus();
                alert('Enter text.');
                } else if (!dropDown.value) {
                    document.getElementById('dropDown').focus();
                    alert('Choose an option.');
                    } else if ( ( newForm.checkbox[0].checked == false ) && ( newForm.checkbox[1].checked == false ) ) 
                        { alert ( "Please choose a checkbox" ); 
                            return false;
                            }

    var radios = document.getElementsByName("radio");
    var formValid = false;
    var i = 0;
    while (!formValid && i < radios.length) {
        if (radios[i].checked) formValid = true;
            i++;        
        }

        if (!formValid) alert("Please check a radio button.");
        return formValid;

        return false;
};
