using of $timeout

Hi everyone,
i am currently trying to make a HoloLense experience with two views, where i can switch between these views with a voice command.

I created an application event "Switch view" and linked it to the "Navigate" option of both views. This works fine, whenever i say "Switch view" it immediatelly switches. 

But now i want to make this a little bit slower, with a delay of 1second for example. I tried to use $timeout but:

How do i use it and where do I have to write the command? (in Home.js or into the JS of the application event)

 

Thank you all for your help!

Here is another approach:

 

That's say we have 2 view, "first" and "second".

In first.js and second.js

 

$scope.app.switchView = function(destination){
  $timeout(function(){
    twx.app.fn.navigate(destination);
  }, 2000)
}

 

 

Then in APPLICATION EVENTS:

Name: firstToSecond

Voice Alias: switch to second view

JS: viewCtrl.app.switchView("second")

 

Name: secondToFirst

Voice Alias: switch to first view

JS: viewCtrl.app.switchView("first")

 

 

View solution in original post

1. Let suppose you have 2 views Home / wich is the the start view and a second view named mySecondVIEW

2. Copy the below script in Home.js

 

$scope.app.mySecondViewCmd = function () { // will call the view "mySecondVIEW"
// with delay 2 secs
$timeout(function() {
  twx.app.fn.navigate("mySecondVIEW")
}, 2000); // call with delay of 2 seconds = 2000 miliseconds
};

 

3. In the js script of the second view in mySecondVIEW.js wirte the code:

 

$scope.app.myViewCmdHome = function () {
$timeout(function() {// will call the home view with 3 secs delay
   twx.app.fn.navigate("Home")
}, 3000); // call with delay of 3 seconds = 3000 miliseconds
}

 

4.) then for the voice command add in the js UI section the function call which should call mySecondView:

 

viewCtrl.app.mySecondViewCmd();

 

 

and for the voice command which should call  back the Home view:

 

viewCtrl.app.myViewCmdHome()

 

 I think the both defintions  of the functions  $scope.app.mySecondViewCmd() and  $scope.app.myViewCmdHome could be done in the start view (so that when this view was called then the definitions are available then)

Here is another approach:

 

That's say we have 2 view, "first" and "second".

In first.js and second.js

 

$scope.app.switchView = function(destination){
  $timeout(function(){
    twx.app.fn.navigate(destination);
  }, 2000)
}

 

 

Then in APPLICATION EVENTS:

Name: firstToSecond

Voice Alias: switch to second view

JS: viewCtrl.app.switchView("second")

 

Name: secondToFirst

Voice Alias: switch to first view

JS: viewCtrl.app.switchView("first")

 

 

Yes, this is better appraoch - more general- using only one deffinition. I see you confirmed that we need to define the function in each view.js - because I did this some time ago and could not remember if the voice command java code defintion will remember the defintion from the start view - also when we navigate to a second view.

Hi, @RolandRaytchev 

 

Thanks for reply. I just try to provide a more general approach.

 

As to Function Declaration  part, here is the clarification:

 

With ".app",

Functions declared in one View can be used in any other Views.

e.g.

$scope.app.switchView = function(destination){
  $timeout(function(){
    twx.app.fn.navigate(destination);
  }, 2000)
}

 

Without ".app

Function can only works in the View in which was declared.

e.g.

$scope.switchView = function(destination){
  $timeout(function(){
    twx.app.fn.navigate(destination);
  }, 2000)
}

 

In other words, $scope.app.switchView be declared in either View is sufficient in my approach above.

 

Sorry for misleading.

That’s   fine, thanks for clarification. Such details are something what we can find during tests , but after some time I could not really remember all the details, so that I appreciate such kind of comments. Thanks!

A big thank you to both of you!!
