Retrieve the value of an attribute within a controller function that is not a directive

Here is some HTML content,

<button data-href="helloworld">Show href Value</button>

And here is some Javascript content,

$("body").on('click', 'button', function(){
    console.log($(this).attr("data-href"));
});

When executed, this will print

helloworld

in the console. I am now transitioning this code to AngularJS,

<div ng-controller="hello">
  <button data-href="helloworld">Show href Value</button>
</div>

var app = angular.module('app',  []);

app.controller("hello", function(){
  // I need assistance with determining what services to inject and 
  //how to structure the logic to display the data-href attribute value
})

Could anyone provide guidance on the hello controller function parameters and implementation?

Answer №1

Transitioning to AngularJS requires a complete reevaluation of your app structure, especially if it heavily relies on selection and DOM manipulation. Angular is designed to streamline these processes, so consider why you need event binding instead of utilizing data bindings or the view model.

For an immediate solution, consider implementing a directive:

<button show-link="helloWorld">Show Link Value</button>

app.directive("showLink", function () {
    return function (scope, elem, attr) {
        elem.bind("click", function () {
            console.log(attr.showLink);
        });
    };
});

Answer №2

One approach in Angular is to declare the value within the controller's scope

<button data-href="{{myLink}}" ng-click="handleClick()">Show Link Value</button>
....
app.controller("sample", function($scope){
     $scope.myLink = 'hello';
     $scope.handleClick = function(){
          console.log($scope.myLink);
     }
})

Alternatively, if you must define data-href in the HTML and access it within Angular code, consider using a directive instead of a controller

Answer №3

let $scope;
const app = angular.module('miniapp', []);

function Controller($scope) {
    $scope.clickEvent = function(Obj) {

        // Display the Obj to view all details
        console.log(Obj);

        // Show only the data value in an alert
        alert(Obj.target.attributes.data.value);

    }
};

HTML

<div ng-app="miniapp">
    <div ng-controller="Controller">
        <a ng-click="clickEvent($event)" class="exampleClass" id="exampleID" data="exampleData" href="">Click Me</a>
    </div>
</div>
