>我正在尝试开发一个具有自己的控制器的指令,以便它可以从API收集所需的数据并注入到任何地方。
这是我到目前为止得到的:
(function () {
'use strict';
angular
.module('app.hostelsmg.bookings')
.directive('bookingsChart', bookingsChart);
function bookingsChart() {
return {
restrict: 'E',
scope: true,
controller: [function(){
$scope.test = 'Hi there!';
}],
compile: function(tElem, attrs){
tElem.html('{{test}}');
return function(scope, elems, attrs){
}
}
}
}
})();
所以我想要的,是从它自己的控制器获取数据的指令。到目前为止,我无法让它以这种方式工作。
有谁知道怎么做?
你可以使用这样的东西
function bookingsChart() {
return {
restrict: 'E',
scope: true,
controller: ['$scope', 'yourservice', function ($scope, yourservice) {
$scope.data = []; //bind this data to your view
$scope.getServiceData = function (count) {
//your service call
yourservice.getServiceData(count).then(function (data) {
$scope.data = data; //sets data in $scope.data variable
});
}
}],
link: function (scope, elements, attributes) {
//if you want to pass any parameters from your UI to your service method
scope.getServiceData(attributes.count); //calls the getServiceData in controller defined above
}
}
}
