AngularJS - how to calculate input field values

Question

I'm looking for a good way to preform a calculation on a couple of inputs and store the total value in a $scope variable as well as a total field (disable).

Here is a jsfiddle - http://jsfiddle.net/U3pVM/18830/

In this case we need to apply unique visit / mobile visit = total visit, store the total in metricData.totalVisit, and set the value of the disabled field to that as well.

Thanks in advance!

Angular provides $watch to do stuff like this. You can simply do something like:

$scope.$watch('metricData', function(metricData) {
    metricData.totalVisit = metricData.uniqueVisit / metricData.mobileVisit;
}, true);

Fiddle: http://jsfiddle.net/j0ajrtzr/

(note this is just an example to demo basic functionality, more info at $scope.$watch)
