HTML content,

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

Js content,

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

This prints

helloworld

in the console. I am migrating the above 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(){
  //someone help me with the services that are to be injected and 
  //and what logic goes here to print the data-href attribute value
})

Can someone help me with the hello controller function arguments and contents?

If you are switching over to AngularJS you will have to start rethinking your app entirely -- it's difficult to make a complete overhaul from an existing app that is using selection and DOM manipulation. Angular is typically used to avoid these. Thus, you should ask yourself why you need to bind to an event rather than using data bindings / the view model.

That's too much to get into here, so to solve your immediate problem you could use a directive.

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

// `data-` prefixes stripped from directives as part of Angular normalization
app.directive("showHref", function () {
    return function (scope, elem, attr) {
        elem.bind("click", function () {
            console.log(attr.showHref);
        });
    };
});

Angular way would be to define value in controller scope

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

However if you really need to define data-href from html and get access to it in angular code that you need to consider using a directive instead of a controller

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

function Ctrl($scope) {
    $scope.clickEvent = function(obj) {

        // Log the obj to see everything
        console.log(obj);

        // Alert just the data value
        alert(obj.target.attributes.data.value);

    }
};

HTML

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