我正在尝试使用Angular的“装饰器”功能向某些指令添加功能。假设我的指令名称是myDirective。我的代码如下所示:
angular.module('app').config([ '$provide', function($provide) { return $provide.decorator('myDirective', [ '$delegate', '$log', function($delegate, $log) { // TODO - It worked! Do something to modify the behavior $log.info("In decorator"); } ]); }
]);
我不断收到此消息:
Uncaught Error: [$injector:unpr] Unknown provider: myDirectiveProvider from app
尽我所能,指令在装饰器函数运行时已被注册。任何见识将不胜感激!
本文说明了实际上如何将带指令的decorator()使用。
您只需将“指令”作为名称的后缀即可。因此,在我的示例中,我应该一直在做
return $provide.decorator('myDirectiveDirective', ['$delegate', '$log', function($delegate, $log) { // TODO - It worked! Do something to modify the behavior $log.info("In decorator"); // Article uses index 0 but I found that index 0 was "window" and index 1 was the directive var directive = $delegate[1]; }
