Password validation is at least 6 character

I wrote some validation code for a password and confirm password that checks if they match or not. Furthermore there is a condition that checks if length of my password is less than 6 characters and writes/displays an error if they are less than 6 characters. But my code doesn't work correctly: when I switch to field 2 the condition of field 1 isn't checked and if both of conditions are correct the error still presents.

Here is my code:

function checkPass()
{
    var pass1 = document.getElementById('pass1');
    var pass2 = document.getElementById('pass2');
    var message = document.getElementById('error-nwl');
    var goodColor = "#66cc66";
    var badColor = "#ff6666";

    if(pass1.value == pass2.value){
        pass2.style.backgroundColor = goodColor;
        message.style.color = goodColor;
        message.innerHTML = "ok!"
    }
    else{
        pass2.style.backgroundColor = badColor;
        message.style.color = badColor;
        message.innerHTML = " These passwords don't match"
    }
	
    if(pass1.length > 5){
        pass1.style.backgroundColor = goodColor;
        message.style.color = goodColor;
        message.innerHTML = "character number ok!"
    }
    else{
        pass1.style.backgroundColor = badColor;
        message.style.color = badColor;
        message.innerHTML = " you have to enter at least 6 digit!"
    }
}

         <input name="password" type="password" placeholder="password"  id="pass1"/>
         <input name="repeatpassword" type="password" placeholder="confirm password" id="pass2" onkeyup="checkPass(); return false;" />
                  <div id="error-nwl"></div>

Solution

Use below code. Firstly, pass1.length is not correct. You should write pass1.value.length. Secondly, I added comparing the 2 blocks at the end, as firstly you should check the length of first block. Also, the function should be called on changes of first block also.

Good luck!

function checkPass()
{
    var pass1 = document.getElementById('pass1');
    var pass2 = document.getElementById('pass2');
    var message = document.getElementById('error-nwl');
    var goodColor = "#66cc66";
    var badColor = "#ff6666";
 	
    if(pass1.value.length > 5)
    {
        pass1.style.backgroundColor = goodColor;
        message.style.color = goodColor;
        message.innerHTML = "character number ok!"
    }
    else
    {
        pass1.style.backgroundColor = badColor;
        message.style.color = badColor;
        message.innerHTML = " you have to enter at least 6 digit!"
        return;
    }
  
    if(pass1.value == pass2.value)
    {
        pass2.style.backgroundColor = goodColor;
        message.style.color = goodColor;
        message.innerHTML = "ok!"
    }
	else
    {
        pass2.style.backgroundColor = badColor;
        message.style.color = badColor;
        message.innerHTML = " These passwords don't match"
    }
}

<input name="password" type="password" placeholder="password"  id="pass1" onkeyup="checkPass(); return false;" />
<input name="repeatpassword" type="password" placeholder="confirm password" id="pass2" onkeyup="checkPass(); return false;" />
<div id="error-nwl"></div>
