I have created a Rate Calculator for wall hanging
where we have to enter dimensions of 3 entities (Picture,Mount ,Frame) that are
width
height
rate
and 4 column is calculation of 3 dimention
Then I have created total rate where the addition of all 4th column is calculated
function btnclick() {
var PictureHeight = document.getElementById('PictureHeight').value;
var PictureWidth = document.getElementById('PictureWidth').value;
var Rate = document.getElementById('Rate').value;
var FinalRate = document.getElementById('FinalRate');
FinalRate.value = parseInt(PictureHeight) * parseInt(PictureWidth) * parseInt(Rate);
var MountHeight = document.getElementById('MountHeight').value;
var MountWidth = document.getElementById('MountWidth').value;
var MountRate = document.getElementById('MountRate').value;
var MFinalRate = document.getElementById('MFinalRate');
MFinalRate.value = parseInt(2 * MountHeight) parseInt(2 * MountWidth) * parseInt(MountRate);
var FrameHeight = document.getElementById('FrameHeight').value;
var FrameWidth = document.getElementById('FrameWidth').value;
var FrameRate = document.getElementById('FrameRate').value;
var FrFinalRate = document.getElementById('FrFinalRate');
FrFinalRate.value = parseInt(2 * FrameHeight) parseInt(2 * FrameWidth) * parseInt(FrameRate);
var TFinalRate = document.getElementById('TFinalRate');
TFinalRate.value = parseInt(FinalRate) parseInt(MFinalRate) parseInt(FrFinalRate);

</html>but when u click on submit it shows NAN in total Rate
CodePudding user response：
there is only one error is that you haven't take the value of TFinalRate.value = parseInt(FinalRate.value) parseInt(MFinalRate.value) parseInt(FrFinalRate.value);
You should use FinalRate.value, FinalRate.value and MFinalRate.value
function btnclick() {
var PictureHeight = document.getElementById('PictureHeight').value;
var PictureWidth = document.getElementById('PictureWidth').value;
var Rate = document.getElementById('Rate').value;
var FinalRate = document.getElementById('FinalRate');
FinalRate.value = parseInt(PictureHeight) * parseInt(PictureWidth) * parseInt(Rate);
var MountHeight = document.getElementById('MountHeight').value;
var MountWidth = document.getElementById('MountWidth').value;
var MountRate = document.getElementById('MountRate').value;
var MFinalRate = document.getElementById('MFinalRate');
MFinalRate.value = parseInt(2 * MountHeight) parseInt(2 * MountWidth) * parseInt(MountRate);
var FrameHeight = document.getElementById('FrameHeight').value;
var FrameWidth = document.getElementById('FrameWidth').value;
var FrameRate = document.getElementById('FrameRate').value;
var FrFinalRate = document.getElementById('FrFinalRate');
FrFinalRate.value = parseInt(2 * FrameHeight) parseInt(2 * FrameWidth) * parseInt(FrameRate);
var TFinalRate = document.getElementById('TFinalRate');
TFinalRate.value = parseInt(FinalRate.value) parseInt(MFinalRate.value) parseInt(FrFinalRate.value);
