Hi @HUANGCONG ,

g_form does not work there, to get a value in a client controller you can use something like this:

$scope.$on("field.change", function(evt, parms) {
if (parms.field.name == 'your_field')
    c.data.yourfield = parms.newValue;
});

Or refer to these links :

Hi,

"g_form" as a global object cannot be used in a widget client controller so its functions are not supported either. Please find below link for solution.

It would be better to know what exactly you want to do in the widget's client controller . You may use something like below ->

var g_form = $scope.page.g_form;

 g_form.setValue('variable_name', 'value');
