Hello everybody!
Is there a way to sequentially execute javascript code in vuforia?
I have a function in which I need to perform a series of actions in a clear order:
1) Call the service and get the data
2) Analyze data from the service
3) Depending on the data analysis, show or hide some elements of the vuforia interface
If i write the code like this:
// Call service
$scope.ServiceCall = function () {
twx.app.fn.triggerDataService("VuforiaThing", "Service");
};
// Anylaze data
$scope.DataAnalyze = function () {
if ($scope.app.mdl['VuforiaThing'].svc['Service'].data.current['OperationStatus'] == "status"){
$scope.app.params.testparam = true;
} else {
$scope.app.params.testparam = false;
}
};
//Manipulate UI
$scope.ManipulateUI = function () {
if ($scope.app.params.testparam == "true"){
$scope.view.wdg['WidgetID']['visible'] = true;
} else {
$scope.view.wdg['WidgetID']['visible'] = false;
}
};
// Execute code after view entry
$scope.$on('$ionicView.afterEnter', function() {
$scope.ServiceCall();
$scope.DataAnalyze();
$scope.ManipulateUI();
});
sometimes it turns out that step 2 is performed earlier than 1 and then an incorrect analysis occurs, since there is no data and, accordingly, at step 3, I perform erroneous actions on the interface elements.
If i try to use "async function" vuforia say
! 'async function' is only available in ES8 (use 'esversion: 8').
I find some solutions like this
but it does not working in Vuforia.
Solved! Go to Solution.
Hello everybody!
Seems i found solution.
First of all we need on our "screen.js" paste such code comment:
/*jshint esversion: 8 */
After that manipulation vuforia studio don't alert async js functions.
example1:
$scope.$root.$on('SomeTwxService-end', async function(evt, arg) {
await $scope.Func1();
await $scope.ManipulateUI();
...
await $scope.Func1();
await $scope.Func2();
await $scope.Func3();
});
example2:
$scope.OpCntrlStateChangedCheck = function () {
var step1_value;
var step2_value;
var step3_value;
var p1 = new Promise((resolve, reject) => {
step1_value= angular.element(document.querySelectorAll('twx-widget[widget-id=\"SomeID1\"] twx-widget-content div label input'));
resolve();
});
var p2 = new Promise((resolve, reject) => {
step2_value= angular.element(document.querySelectorAll('twx-widget[widget-id=\"SomeID2\"] twx-widget-content div label input'));
resolve();
});
var p3 = new Promise((resolve, reject) => {
step3_value= angular.element(document.querySelectorAll('twx-widget[widget-id=\"SomeID3\"]'));
resolve();
});
Promise.all([p1, p2, p3]).then(value => {
if (SomeValue == "learn") {
for (var x0=0; x0 < $scope.view.wdg['repeater-2']['data'].length; x0++) {
Step1_value[x0].disabled = true;
}
} else {
for (var x1=0; x1 < $scope.view.wdg['repeater-2']['data'].length; x1++) {
Step1_value[x1].disabled = false;
}
}
for (var x2=0; x2 < $scope.view.wdg['repeater-2']['data'].length; x2++) {
if (step1_value[x2].checked == step2_value[x2].checked) {
step3_value[x2].className = "ControlValueCheckbox checkbox-balanced";
} else if (step1_value[x2].checked != step2_value[x2].checked) {
step3_value[x2].className = "ControlValueCheckbox checkbox-assertive";
}
}
});
};
I tested functionality in the vuforia studio and on mobile vuforia view application seems to work fine.
It may be useful for other community members.
Have you tried to listen on serviceInvokeComplete?
Like this example.
$scope.$on('getModelURL.serviceInvokeComplete', function() {
$scope.view.wdg['model-4']['src'] = $scope.app.mdl['remoteDesignShareUtils'].svc['getModelURL'].data.current['result'];
$scope.app.mdl['remoteDesignShareUtils'].svc['copyRep2FileRepowJSON'].data.current['result'];*/
});
