Angular Directives in Error

Help needed with creating a custom directive in Angular. Seeking guidance :)

I am trying to display the content from 'directive.html' within the 'app-info' directive. The code functions properly without the directive, indicating a mistake in how I am implementing it.

Cheers!

Angular.js file

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

app.controller("mainController", ["$scope", function($scope){
    $scope.list = [
        {
            name: "Joe",
            age: 26,
            job: "Front-End Developer",
            skill: 0
        },
        {
            name: "Rob",
            age: 23,
            job: "Ruby Developer",
            skill: 0
        },
        {
            name: "Mark",
            age: 25,
            job: "Back-End Developer",
            skill: 0
        }
    ];

    $scope.skill = function(index) {
        $scope.list[index].skill += 1;
    };
}]);

app.directive("appInfo", function(){
    return {
        restrict: "E",
        scope: {
            info: "="
        },
        templateUrl: "directive.html"
    };
});

Directive html file

<li>{{ item.name }}</li>
<li>{{ item.age | currency }}</li>
<li ng-click="skill($index)">{{ item.skill }}</li>

Answer №1

After reviewing the code, I have identified a couple of issues that need to be addressed:

Firstly, in your directive.html file, make sure to use {{info.name}} instead of {{item.name}}, as your directive scope variable is named info.

Secondly, don't forget to update the name of your directive in the HTML file from "app-Info" to "app-info".

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8>
  <title>angular</title>
</head>
<body ng-app="angularApp">
  <div ng-controller="mainController">
    <ul ng-repeat="item in list">
         <app-info info="item"></app-info>
    </ul>
  </div>
  <script src="https://code.jquery.com/jquery-3.1.0.slim.min.js"></script>
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
  <script type="text/javascript" src="angular.js"></script>
</body>
</html>

Directive.html

<li>{{ info.name }}</li>
<li>{{ info.age }}</li>
<li ng-click="skill($index)">{{ info.skill }}</li>

In my opinion, the directive you are using should be enclosed within a parent tag like a div tag or any other tag. It is essential to have a single root element.
