I have a button called "letsgo". When it is clicked I want to make sure that both a text area (Notes) and a a text field (theperson) are populated. Could someone help me with the "if" part of my validation below? Thank you.

	window.onload = function() {
    document.getElementById("letsgo").onclick = function() {
        var TextArea = document.getElementsByName("Notes")[0];
        var TextField = document.getElementsByName("theperson")[0];
        if ..................
        {
            alert("Please enter a Person and Notes."); 
            return false;
        }
        return true;
    }
}

I ended up using the below. I needed both required and 1 text area and 1 text field.

Thank you for the assistance.

if (TextArea.value.length==0 || TextArea.value.length==0)

here is a jquery solution:

         $('#letsgo).bind('click', function (event) {
                document.getElementById("letsgo").onclick = function() {
                if( $('#Notes').val() == '' ) {
                    alert("Please enter a value for the Notes Field."); 
                    return false;
               } else if ( $('#theperson).val() == '' ) {
                   alert("Please enter a value for the Person Field."); 
                   return false;
              } else
                    return true;
    }
}
