AngularJS 调用嵌入在另一个控制器中的 ng-controller

Question

Here is a snippet of the cshtml:

<div>
    <button type="button" ng-click="recalcButton()">Recalc Button</button>
</div>
<div ng-controller="appealPartialController">
    <div ng-include="'/Partials/appealsPartial.html'"></div>
</div>

When recalcButton is clicked, I want to reload the data in appealPartialController. Any documentation or JS code examples would be greatly appreciated!

Answer 1

因此，经过大量的谷歌搜索和一个好主意的仙女，我找到了一个利用angularJS 的内置 $scope 并从父级调用加载函数的解决方案。

$scope.$$childHead.$$nextSibling.loadAppealModel($scope.claimID);

Answer 2

You can use a shared param. First of all you create a service like this:

import { Injectable, EventEmitter } from '@angular/core';
import { Subscription } from 'rxjs/internal/Subscription';

@Injectable({
  providedIn: 'root'
})
export class SharedParamsService {

  invokeFirstComponentFunction = new EventEmitter();
  subsVar: Subscription;

  constructor() { }

  onUpdateEnv(key, val) {
    var toEmit = [key, val]
    this.invokeFirstComponentFunction.emit(toEmit);
  }
}

Now you can emit a variable when clicking your button, so in your component, after importing SharedParamsService and declaring in your constructor private sharedParams: SharedParamsService:

recalcButton(){
    this.sharedParams.onUpdateEnv("btn", this.jobObj.name);
}

Finally, in the component you want to reload after importing SharedParamsService and declaring in your constructor private sharedParams: SharedParamsService:

 this.sharedParams.subsVar = this.sharedParams.
     invokeFirstComponentFunction.subscribe((emitted) => {
        if (emitted[0] == "btn") {
            this.ngOnInit();
        }
      });

of course you can avoid using the key, val way if you have only this button to check, but using this way you can subscribe to multiple buttons toggles or other variables.
