Answer 1

Instead of doing document.getElementById("toai").innerHTML=+totaltoai; in the toai() function you can return the value.

<script>
function toai()
{
var Fr_amt_invt  = document.getElementById("Fr_amt_invt").value;
var Re_amt_invt  = document.getElementById("Re_amt_invt").value;
Fr_amt_invt = parseFloat(Fr_amt_invt);
Re_amt_invt = parseFloat(Re_amt_invt);
var totaltoai = (Fr_amt_invt + Re_amt_invt);
totaltoai = parseFloat(totaltoai);
//document.getElementById("toai").innerHTML=+totaltoai; // delete this
return totaltoai;
}

Then you can do document.getElementById('some-inputs-id').value = toai();
