Sending information between parent and child components in AngularJS is a common task that can be accomplished using various methods

Is there a way to pass data from the Main Controller (index) to the Sub Controller (Component)? In this scenario, instead of hardcoding the url, I want to send the parameters for the Title and the URL from the main controller to the component. I'm encountering difficulties with sending this information and troubleshooting where the issue lies.

index.html

<div>
  <my-list obj="vm.obj"></my-list>
</div>

index.controller.js

this.obj = {
    testURL: "AngularJS",
    testName: "Testing Environment
}

mylistComponent.html

<span>{{vm.myTestName}}</span>
<a href="https://en.wikipedia.org/wiki/{{vm.myTestURL}}">AngularJS Wikipedia</a>

mylist.Component.js

binding: {
    obj: "="
}

this.goToPage = function() {
    this.myTestName = this.obj.testName;
    this.myTestURL = this.obj.testURL;
}

PLUNKER

Answer №1

When utilizing your plunker, make sure to follow these steps:

<test-component value="vm.obj"> </test-component>

By implementing the above code, you are assigning the value of obj to the variable value. This means that in the child scope, you will need to refer to this value using the variable value, rather than obj.
