Here I am validating password if function one credential is right it says no user found first and says validation succeeded and wise versa. How to get rid of it .

function validate()
    {
        if(   document.getElementById("user").value == "admin"
           && document.getElementById("psw").value == "password" )
        {
            alert( "validation succeeded" )
            
                
        }
        else
        {
            alert( "validation failed" );
           
        }
    }
    
    
    
    
    //local storage validation
    
    function validlogin(event) {
      var user = document.getElementById('user').value;
      var psw = document.getElementById('psw').value;
    
      var items = JSON.parse(localStorage.getItem('login'));
    
      for (let i = 0; i < items.length; i++) {
    
        if (items[i].username == user && items[i].password == psw)
          {
    
          alert("Succesfully logged in");
          return;
          
          }
         alert("Invalid Credential")
         event.preventDefault();
        window.location = "test.html";
    }
      }

windows.load is notworking instud form action is working but need to redirect different page.
