问题描述
你如何手动注入的角度镖一个实例?这将是等同于以下中angularjs:
VAR myInjector = angular.injector([NG]);
变量$ HTTP = myInjector.get($ HTTP);
解决方案
从组件内部的code的例子。
@NgComponent(
选择:评级,
publishAs:CTRL)
类RatingComponent {
喷油器_injector;
RatingConfig _config; RatingComponent(this._injector){
_config = _injector.get(RatingConfig);
// 要么
_config = injectByName(RatingConfig);
} 无效injectByName(字符串的typeName){
_injector.types.takeWhile((E型){
如果(e.toString()==的typeName){
_config = _injector.get(E);
返回false;
}
返回true;
});
}
}
How do you manually inject an instance in angular dart? This would be the equivalent to the following in angularjs:
var myInjector = angular.injector(["ng"]);
var $http = myInjector.get("$http");
解决方案
A code example from inside a component.
@NgComponent(
selector: 'rating',
publishAs: 'ctrl')
class RatingComponent {
Injector _injector;
RatingConfig _config;
RatingComponent(this._injector) {
_config = _injector.get(RatingConfig);
// or
_config = injectByName("RatingConfig");
}
void injectByName(String typeName) {
_injector.types.takeWhile((Type e) {
if (e.toString() == typeName) {
_config = _injector.get(e);
return false;
}
return true;
});
}
}
