Adding numeric value from textbox into another textbox

I have been looking for this script everywhere however i was unable to find it. I am trying to create a simple donation count. When a value is added inside a textbox I want it to be permanently fixed into second textbox after button submission. Thanks in advance for all your help.

Try this:

<script>
window.onload = function () {
    var textfield6 = document.getElementById('textfield6');
    textfield6.value = 0;
    document.querySelector('input[type=button]').onclick = function () {
        textfield6.value = parseInt(textfield6.value) + parseInt(document.getElementById('textfield5').value);
    }
}
</script>

1) First get the value from textBox1 (assuming id=textbox1)
2) Assign the value to second textbox (assuming id=textbox2)
3) Add the below code in form submission or button click. 

document.getElementById('textbox2').value =
              document.getElementById('textbox1').value
