Angular JS views not updating properly

问题

I have the following action

ng-click in my view -> which inturn calls a jQuery ajax function that displays jQuery Qtip -> In the Qtip popup I have an ng-click on an element -> which performs a $http post and has some callbacks to update $scope values.

So all these things are happening properly. But the updates are not getting reflected in the view as per the changes made in the callback in the final stage.

I have a function for "ng-mousemove" in my view. So whenever I move my mouse, the updates in the view are getting reflected.

What am I doing wrong here? Is the because of transitioning between angular and non-angular? Can anyone help me how to solve this?

回答1:

As the docs explains:

$apply() is used to execute an expression in angular from outside of the angular framework. (For example from browser DOM events, setTimeout, XHR or third party libraries). Because we are calling into the angular framework we need to perform proper scope life-cycle of exception handling, executing watches.

So if you have a jQuery code like

$('#myDiv').on('click', function() {
  // do stuff
  $scope.$apply();
});

You have to tell angular Js something has changed with $scope.$apply().

Here is a nice blog on why: http://www.yearofmoo.com/2012/10/more-angularjs-magic-to-supercharge-your-webapp.html#apply-digest-and-phase
