first of all, my skills in programming etc. are almost zero, but I would like to try a few things out and now I am stuck with a problem (which isnt probably one for everyone else here).
I have aligned the table and the column names to the example of this link and copy paste the code into the JS console, but nothing happened. Does somebody knows why or could potentially help? Again, probably an easy fix, but as I said, no coding experience/know-ledge here at all.
Dear Felix,
Can you show me where you've copied the code to? Also, check browser's console for errors - these will help us determine what goes wrong. Screenshots would help!
I tried to add them together with OrderTotal into the new field Total Sum on the right by adding a new variable that is called sumtotal and add orderTotal with the field OtherCostsVAT. However, I struggel with getting the value out of OtherCostsVAT and add them to orderTotal in order to calculate the new sumtotal (see code below):
The calculation to sumtotal works fine if I add e.g. orderTotal + orderTotal, so I think its because I cannot obtain the value out of the Other Cost VAT field. Would you have a fix for that?
Dear @ffaupel,
You can just access these fields directly in your calculation. Can you copy and paste your code as text, so I can adjust it a little for you?
fd.rendered(function() {
//Disable OrderTotal field
fd.field('OrderTotal').disabled = true;
fd.field('TotalSum').disabled = true;
//Make LineTotal column noneditable
fd.control('DataTable1').columns[4].editable = function(){return false};
fd.control('DataTable1').$on('change', function(value) {
//variable to count Order Total
var orderTotal = 0.0;
var sumtotal = 0.0;
//if there are records in the table
var modifiedValue = null;
if(value){
//go through each one by one
for (var i = 0; i < value.length; i++){
//if this record has Amount and UnitPrice
if(value[i].Amount && value[i].UnitPrice){
//set LineTotal to their product
var cost = value[i].Amount * value[i].UnitPrice;
if (value[i].LineTotal !== cost) {
if (!modifiedValue) {
modifiedValue = Object.assign({}, value);
}
modifiedValue[i].LineTotal = cost;
}
}
//add Total to the Order Total
orderTotal += parseFloat(value[i].LineTotal);
console.log(orderTotal);
sumtotal += orderTotal + 'OtherCostsVAT';
console.log(sumtotal);
}
}
//here we refresh the table
if (modifiedValue) {
fd.control('DataTable1').value = value;
fd.control('DataTable1').widget.refresh();
}
//we set Order Total field to sum of Totals
fd.field('OrderTotal').value = orderTotal;
fd.field('TotalSum').value = sumtotal;
});
});

//Disable OrderTotal field
fd.field('OrderTotal').disabled = true;

if (modifiedValue) {
fd.control('DataTable1').value = value;
fd.control('DataTable1').widget.refresh();
}
//we set Order Total field to sum of Totals
fd.field('OrderTotal').value = orderTotal;
fd.field('TotalSum').value = orderTotal + fd.field('ShippingFee').value + fd.field('OtherCostsVAT').value;
});
});
Just need to change the Names for the two fields ShippingFee and OtherCostsVAT that you want to add to the sum.
thanks so much, it works super well :)! Just one thing I noticed, when I add the inputs for Shipping Fee and Other Costs, it adds up, but when I change the Shipping Fee and Other Costs value, the Total Sum does not update.
Is there any code that would update the values from both fields once changed and refresh the total sum field?
Sorry for asking all of these questions, I hope you don't mind Again, thanks so much!!
Dear @ffaupel,
You're right, the code only runs when the DataTable value changes. I would recommend to split the code inside of a function, and call it on change in either one of the fields or in the DataTable, like this:
function calculateTotal(){
var value = fd.control('DataTable1').value;
//variable to count Order Total
var orderTotal = 0.0;
var sumtotal = 0.0;
//if there are records in the table
var modifiedValue = null;
if(value){
//go through each one by one
for (var i = 0; i < value.length; i++){
//if this record has Amount and UnitPrice
if(value[i].Amount && value[i].UnitPrice){
//set LineTotal to their product
var cost = value[i].Amount * value[i].UnitPrice;
if (value[i].LineTotal !== cost) {
if (!modifiedValue) {
modifiedValue = Object.assign({}, value);
}
modifiedValue[i].LineTotal = cost;
}
}
//add Total to the Order Total
orderTotal += parseFloat(value[i].LineTotal);
console.log(orderTotal);
}
}
//here we refresh the table
if (modifiedValue) {
fd.control('DataTable1').value = value;
fd.control('DataTable1').widget.refresh();
}
//we set Order Total field to sum of Totals
fd.field('OrderTotal').value = orderTotal;
fd.field('TotalSum').value = orderTotal + fd.field('ShippingFee').value + fd.field('OtherCostsVAT').value;
}
fd.rendered(function() {
//Disable OrderTotal field
fd.field('OrderTotal').disabled = true;
fd.field('TotalSum').disabled = true;
//Make LineTotal column noneditable
fd.control('DataTable1').columns[4].editable = function(){return false};
fd.control('DataTable1').$on('change', function() {
calculateTotal();
});
fd.field('ShippingFee').$on('change', function() {
calculateTotal();
});
fd.field('OtherCostsVAT').$on('change', function() {
calculateTotal();
});
});
It works well, thanks a lot for your support!!!
