I use Typescript with Angular and Breezejs.
class CounterController {
count: number = 0;
static $inject = ['$scope'];
constructor($scope) {
$scope.vm = this;
}
setCount14(): void {
this.count = 14; // works
}
getQuestions(): void {
var manager = new breeze.EntityManager('/breeze/dbentities');
var query = breeze.EntityQuery.from("Corporations").where("Name", "startsWith", "Zen");
manager.executeQuery(query)
.then(querySucceeded);
function querySucceeded(data) {
this.count= 1; // works not!
}
}
}
How can i access the count
property in the querySucceeded
function correct?
Edit: better: there must be a way to pass a typescript function to executeQuery(query).then
?
Solution: Pass Typescript function as a Javascript function
Then calling the scope.$apply()
does apply the bindings.
use (data) => { this.count = 1; }
(data) => { this.count = 1; }
instead. or your "this" won't have the correct scope. OR as an alternative:
var me = this;
function querySucceeded(data) {
me.count= 1; // works not!
}
eg:
getQuestions(): void {
var manager = new breeze.EntityManager('/breeze/dbentities');
var query = breeze.EntityQuery.from("Corporations").where("Name", "startsWith", "Zen");
manager.executeQuery(query)
.then((data) => { this.count= 1; });
}
