For and while loops

Jacques TUR
Last edited 295 days ago by Jacques TUR.
A for loop can be used to execute code and/or return an array of values. The type of the returned array corresponds to the type of the last statement between do and end.
⁠

For Loop

Looping Throu

for i from 1 to 10 do
i;
end;

Looping Through an Array:

var myArray := [1, 3, 5, 7];
for i in myArray do
i;
end;

Looping Through Keys and Values of a JSON Object:

var config := {
sep: ",",
qut: """",
lf: "%0D%0A",
numberFormat: "point",
dateFormat: "locale",
header: true,
sepHeader: false,
encoding: "utf8"
};

for key, value in config do
key + " = " + value;
end;
arrow
See how to manipulate JSON variables in Ninox:
Special Variables / JSON
⁠
.
⁠
⁠
it is possible to do the same with a record, but you need to use
NativeJS from Ninext
⁠
to transform a record (nid) into JSON:
var rec := (first(select Customer));

"Transforming a record into a JSON object"
var config := #{:any return rec}#;

for fieldName, value in config do
fieldName + " = " + value;
end;
This approach can be useful for exporting all fields of a table into formats like CSV.

⁠

While Loop

about
While loops are simple and do not return any value. They are used solely for performing iterative tasks and cannot be used to build arrays.

Example:

var a := 1;
while a < 10 do
a := a + 1;
end;
For Loop
Looping Throu
Looping Through an Array:
Looping Through Keys and Values of a JSON Object:
While Loop
Example:
Want to print your doc?
This is not the way.
Try clicking the ⋯ next to your doc name or using a keyboard shortcut (
CtrlP
) instead.
