Call a function on changed value event

Call a function on changed value event

Hi everyone,

I would like to call a function on changed value event. How can I do this?

The value to be monitored is in a label, it is used to indicate the step of my animation. The property text of label is binded to CurrentStep of my 3D Model which contains animation sequences.

Thanks,

 

Maxime.

Hello @MaximeDid ,

one possible option to define a change value event and to call an action when a widget property will chang   , is to use  the $watch angular construct / defintion in  javascript e.g. in the Home.js -> some code like this:

 

 $scope.$watch("view.wdg['label-1']['text']", 
         function (newValue, oldValue, scope) {
console.log("Old Value -befor it was changed =" + oldValue); 
//! it could be undefined first time called
console.log("new  Value -after it was changed =" + newValue); 
//prints the current $scope (copy) object passed to the $watch construct
// pay attention it has no $ !
console.warn(scope);// the scope variable passed to the function
// this is the same as $scope but has not the $-char
})
