1.) Get the DOM object of the element

var elem = document.getElementById("total");

2.) Set the value

elem.value = your_variable;

Example:

var Counter = 0;
var elem = document.getElementById("total"),
while(condition == true) {
    // some code
    Counter++;
    elem.value = Counter;
}

You can get the value of form field by Javascript DOM API.

<script lang=”text/javascript”>
var total = document.getElementById("total").value;

Var counter;
Loop{
Some Code . . . . 
Counter++;
}//end loop
