I have an AngularJS page with several form inputs.
When the some of the inputs have focus, I want to change other, arbitrary, aspects of the page.
For example, when the user is in the 'stock code' input, I want to display the list of popular stock codes. When they are in the 'qty' field I want to show in-stock quantities and lead times.
Is there a variable which contains the 'current' input (the one which has focus), or do I need to revert to jQuery's onFocus. (It seems a little primitive now.)
How about make a directive? You could set a variable whenever the user leaves/enters the input, and detect that: http://jsfiddle.net/TZnj2/
Be sure to read the directive guide if you're confused as to what's happening: http://docs.angularjs.org/guide/directive
Also I use scope.$apply in that directive, here's an explanation of what that does: http://docs.angularjs.org/api/ng.$rootScope.Scope#$apply
