Is it possible queuing ng-init? Generally, in first init I want to add JSON file to prototype vars (array) and in another init depending on the params I want to skip getJsonData() or add other JSON file to prototype.
function init(param) {
console.log("startInit");
// big JSON file
var promise = getJSON(param);
return promise.then( function() {
//some func
console.log("finish");
return true;
});
};
function getJSON(param) {
var deferred = $q.defer();
console.log("startInitDataInner");
someService.getJsonData(param).then(function(data) {
// some code
console.log("endInitDataInner");
deferred.resolve();
}, function(error) {
deferred.reject();
});
return deferred.promise;
};
in view ng-init
ng-init="init(param)"
ng-init="init(param)"
// ...
and log:
startInit
startInitDataInner
startInit
startInitDataInner
endInitDataInner
finish
endInitDataInner
finish
//..
Edit:
Generally, I want to create something like plugin in jQuery. I have this code:
<div ng-controller="parentController as parent">
<div ng-controller="childController as child" ng-init="child.init(parent.data)"></div>
</div>
<div ng-controller="parentController as parent">
<div ng-controller="childController as child" ng-init="child.init(parent.data2)"></div>
</div>
and configurable part by user:
angular.module('myApp').controller('parentController', ['$scope', function($scope) {
this.data = {
config: {
lang: "en",
title: "title"
}
};
this.data2 = {
config: {
lang: "pl",
title: "title2"
}
};
}]);
ng-init update api:
angular.extend(this, parent.data);
Do you have any ideas how I should do it differently?
Well, if you are working with angular, you use controllers. What is controller itslfmin general meaning? Right, its a constructor function. The main word here is function . What does function in general? Run the code inside.
So, just place your initial logic at the beggining of controller code (but without wrapping it as a separate function) and it will run just in time your controller will be resolved by angular resolver.
var controller = function () {
// vars, costs, etc.
console.log("startInit");
// big JSON file
var promise = getJSON(param);
return promise.then( function() {
//some func
console.log("finish");
return true;
});
};
