ng-angular: Angular Custom Directive and Transclusion Sample

In this tip, you can see an example of using Angular JS transclusion, which means to insert one part of a document into another by reference. When a custom directive wraps arbitrary content, the transclusion can be an elegant approach. Below you can see a directive that represents a popup container, and how the transclusion is used to nest arbitrary content in it:

<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<script src="../angular/angular.min.js"></script>
<link href="./css/popup.css" rel="stylesheet"/>
<script type="text/ng-template" id="popupTemplate">
<div id="popupTrigger">
<div id="popupText">{{popuptitle}}</div>
<div id="popupContainer">
<div id="popupContent">
<div ng-transclude></div>
</div>
</div>
</div>
</script>
<script>
angular.module("appModule", [])
.controller("appCtrl", function ($scope) {
$scope.players = [
{ name: 'Nadal, Rafael (ESP)', rank: 1, age: '28', prizemoney: 66149345 },
{ name: 'Djokovic, Novak (SRB)', rank: 2, age: '27', prizemoney: 70704129 },
{ name: 'Federer, Roger (SUI)', rank: 3, age: '33', prizemoney: 84827704 },
{ name: 'Wawrinka, Stan (SUI)', rank: 4, age: '29', prizemoney: 13155060 },
{ name: 'Ferrer, David (ESP)', rank: 5, age: '32', prizemoney: 24034072 },
{ name: 'Tsonga, Jo-Wilfried (FRA)', rank: 11, age: '29', prizemoney: 1708240 },
{ name: 'Simon, Gilles (FRA)', rank: 26, age: '29', prizemoney: 760469 },
{ name: 'Lopez, Feliciano (ESP)', rank: 20, age: '33', prizemoney: 1100579 },
{ name: 'Benneteau, Julien (FRA)', rank: 28, age: '32', prizemoney: 617688 },
{ name: 'Verdasco, Fernando (ESP)', rank: 33, age: '30', prizemoney: 689219 },
{ name: 'Mayer, Leonardo (ARG)', rank: 25, age: '27', prizemoney: 946294 }
];
})
.directive("popup", function () {
return {
template: function () {
return angular.element(
document.querySelector("#popupTemplate")).html();
},
scope: {
popuptitle: "@titleattr"
},
restrict: 'E',
transclude: true
}
});
</script>
</head>
<body>
<div ng-app="appModule" ng-controller="appCtrl">

<popup titleattr="Player Bio">
<h4>Rafael Nadal Bio</h4>
