javascript else statement return true only when everything is filled in correctly

I am a novice in JavaScript and I have a question. Maybe he has already been answered, but I could not find the answer (links to the answer are welcome!). I have made a small form that checks whether everything has been filled in correctly. I use the "if / else" statement in my code to check the input. In the cosole.log he returns 'true' while he has to return 'false' because I have not entered anything in the input boxes. I want my "else" statement to return "true" only when everything is filled in correctly.

Thank you in advance.


validation.js

function validate() {
           var fields = f1.getElementsByTagName('input');
           var attribute = [];
           for (i = 0; i < fields.length; i++) {
               if (fields[i].type != "submit") {
                   attribute.push(fields[i].getAttribute('validate').split('|'));
               }
           }

           var name = document.f1.name.value;
           var namelength = document.f1.name.value.length;
           var status = false;
           var emptyName = attribute[0][0];

           ////////////////////////////////////////////////////////////////
           // CHECK NAME
           ////////////////////////////////////////////////////////////////

           if (emptyName == "empty-allowd") {
               emptyName = 0;
           }
           if (emptyName == "empty-not-allowd") {
               emptyName = 1;
           }
           if (emptyName == 0) {
               document.getElementById("namelocation").innerHTML = "ok";
               status = true;
           }
           if (emptyName == 1) {
               document.getElementById("namelocation").innerHTML = "Required.";
               status = false;
           }
           if (namelength > 0 && namelength < attribute[0][1]) { 
               document.getElementById("namelocation").innerHTML = "Name not shorter than" + " " + attribute[0][1] + " " + "characters.";
               status = false;
           }

           status = true;
           console.log(status);
           alert(status);
           } 

      return status;
