You can use server method to send a request to the server to execute a function defined in the server module of an item.
En the example below we create the btn
button that is a JQuery object.
Then we use its click method to attach a function that calls the
server
method of the item to run the calculate
function defined in the server module
of the item.
The code in the client module:
function on_view_form_created(item) {
var btn = item.add_view_button('Calculate', {type: 'primary'});
btn.click(function() {
item.server('calulate', [1, 2, 3], function(result, error) {
if (error) {
item.alert_error(error);
}
else {
console.log(result);
}
})
});
}
The code in the server module:
def calculate(item, a, b, c):
return a + b + c
