HTML:

<form id="registerform3" method="post" name="registerform3" action="finish.html"  önsubmit="checkPass();my();">
<input type="submit">
</form>

I want to trigger two functions on onsubmit event. can it be possible? and if yes than how?

Javascript:

function my()
{ var pass1 = document.getElementById('setpassword');
    var pass2 = document.getElementById('confirm');

    var message = document.getElementById('message1');
	

    var goodColor = "#0C6";
    var badColor = "#FF9B37";
	 if(pass1.value.length>=8){
        
        pass1.style.backgroundColor = goodColor;
       message.style.color = goodColor;
	 
        message.innerHTML = "Password Accepted!";
	return true;
    }else {
   
        pass1.style.backgroundColor = badColor;
		
        message.style.color = badColor;
        message.innerHTML = "Minimum 8 characters!";
		return false;
    }
}
function checkPass()
{


    var pass1 = document.getElementById('setpassword');
    var pass2 = document.getElementById('confirm');
    
    var message = document.getElementById('message2');

   var goodColor = "#0C6";
    var badColor = "#FF9B37";
  
    if(pass1.value == pass2.value){
       
	   
        pass2.style.backgroundColor = goodColor;
        message.style.color = goodColor;
        message.innerHTML = "Matching!";
		return true;
		
		
    }else {
      
        pass2.style.backgroundColor = badColor;
        message.style.color = badColor;
        message.innerHTML = "Doesn't Matching!";
		return false;
	
	
    }
	
	
	
}

Event handlers in HTML (like onsubmit) are uing JavaScript code, so writing return something; will stop the execution flow.
If you want to execute multiple function you can do two things:
1. Create a function that calls upon all others (preferred IMHO)

HTML

<form ...  önsubmit="return(onSubmit());">

JavaScript

function onSubmit()
{
  var rv = checkPass();

  my();

  // other thing to do

  return(rv);
}

2. Write in event handler all the functions you want to call: onsubmit="chcekPass();my();"

Your change is seem all right - that will execute both functions before posting the form. However if you want to use these function to stop the flow in certain cases, it's not good. It also not too goo as writing practice...
As I told, the best way is wrapping all your function into one and use it - see updated answer...
