AngularJS: Troubleshooting scope problems within a directive while utilizing $compile

Having trouble with scope loss during compilation for a dynamic template in my directive. Here's the condensed code snippet:

(function () {
'use strict';

angular.module('cdt.dm.directives').directive('serviceSources', ['$http', '$templateCache', '$compile', '$parse',
function ($http, $templateCache, $compile, $parse) {
    return {
        restrict: 'E',
        replace: true,
        scope: {
            type: '=',
            sources: '='
        },
        link: function (scope, element, attr) {
            var template = 'Template_' + scope.type + '.html';

            $http.get(template, { cache: $templateCache }).success(function (tplContent) {
                element.replaceWith($compile(tplContent)(scope));
            });

            $compile(element.contents())(scope);
        }
    }
}
])
})();

This implementation successfully loads the HTML template.

The structure of the HTML template is as follows:

<table>
<thead>
    <tr>
        <th>File</th>           
    </tr>
</thead>
<tbody data-ng-reapeat="src in sources">
    <tr>
        <td>{{src.fileName}}</td>
    </tr>
</tbody>

Sources is an array with two elements. While the scope of the directive confirms this, the ng-repeat in the template doesn't function properly at this stage (likely due to sources being undefined).

Any insights on what might be causing this issue?

Answer №1

I believe there is a mistake in your code: using ng-repeat instead of data-ng-reapeat, and ng-repeat should be placed on <tr>

<table>
<thead>
    <tr>
        <th>File</th>           
    </tr>
</thead>
<tbody>
    <tr ng-repeat="src in sources">
        <td>{{src.fileName}}</td>
    </tr>
</tbody>

Please note that $http.get is asynchronous, so make sure to wrap the code inside scope.$apply. Your modified code should look like this:

link: function (scope, element, attr) {
            var template = 'Template_' + scope.type + '.html';

            $http.get(template, { cache: $templateCache }).success(function (tplContent) {
              scope.$apply(function(){ 
                element.replaceWith(tplContent);
                $compile(element)(scope);
               });
            });
        }
