Working on a reporting application where reports are generated (in HTML) from a BIRT Report Engine object. The report data comes as a JSON string is recieved from XHR. The JSON string contains a combination of HTML and javascript (a function call, specifically). Once received, the report data is stuffed into a for display in the view. The view is put together using AngularJS.
I did some research and found that binding the HTML/javascript to the view in Angular requires the use of $compile. Using that as a basis, i put together some code that will include data and execute code bound from a string defined explicitly in the $scope. But - unless i'm going overlooking something after staring at the same stuff for a couple hours, the approach i'm using does not work with $scope data defined by XHR. Here's a plunkr to show the general idea implemented. Any suggestions would be greatly appreciated.
The HTML
<!DOCTYPE html>
<html data-ng-app="example">
<head lang="en">
<meta charset="UTF-8">
<title></title>
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.10/angular.js"></script>

<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.20/angular-sanitize.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="controller" >
<h1>Static Content</h1>
<p><button href="javascript: void(null)" role="link" ng-click="loadSubreport('recv_po_detail.rptdesign', 'static')">PO000007</button></p>
<h1>HTML from static string</h1>
<div compile="snippet"></div>
<h1>HTML from server string</h1>
<div compile="html.body"></div>
<hr />
<button ng-click="alert()">Show XHR Data</button>
</body>
</html>
The Javascript
var app = angular.module('example', []);
app.controller('controller', ['$scope', '$compile', '$http', function ($scope, $compile, $http){
$scope.snippet="<p><button href=\"javascript: void(null)\" ng-click=\"loadSubreport('recv_po_detail.rptdesign', 'compiled')\">PO000007</button></p>";
$http.get('data.json')
.success(function (data) {
$scope.html = data;
});
$scope.loadSubreport = function (filename, source) {
alert("Called from " + source);
};
$scope.alert = function () {{
alert($scope.html.body);
}}
}]);
app.directive('compile', ['$compile', function ($compile) {
"use strict";
return function (scope, element, attrs) {
var ensureCompileRunsOnce = scope.$watch(
function (scope) {
return scope.$eval(attrs.compile);
},
function (value) {
element.html(value);
$compile(element.contents())(scope);
ensureCompileRunsOnce();
}
);
};
}]);
