title: jQuery validating multiple form fields
body: <p>Fairly new to jquery but I realize my code could be condensed. It works just fine but there's got to be a better way to do this as it kind of seems like redundant code. I've got two input fields and a textarea that I'm validating see below. Code samples would be ideal since I'm still learning but any help is appreiacted:</p>
  
  <pre><code>$("form#designForm").submit(function(){
  
      if($("#ccDesignFirstName").val().length == 0){
        alert("Full Name field is required");
        $("#ccDesignFirstName").focus();
        return false;
      }        
  
      if($(".telephoneInput").is(":visible")){
          if($("#ccDesignTelephone").val().length == 0){
            alert("Phone is required");
            $("#ccDesignTelephone").focus();
            return false;
          }
      }
  
      if($("#ccDesignProblem").val().length == 0){
        alert("Question is required");
        $("#ccDesignProblem").focus();
        return false;
      }
  });
  </code></pre>
