Obtaining Compiled HTML Output Using AngularJS

I'm running into an issue with obtaining the compiled html of a page in AngularJS. Below is the code snippet that demonstrates this problem:

JavaScript:

    <script src="http://code.angularjs.org/1.2.0rc1/angular.min.js"></script>
    <script>
        var app = angular.module('main', []);

        app.directive("compile", ['$compile', function ($compile) {
            return {
                link: function(scope, elem, attr){
                    var compiledHTML = $compile(elem.contents())(scope);
                    console.log(compiledHTML);
                    var returnString = '';
                    for(i=0; i<compiledHTML.length; i++)
                        returnString += compiledHTML[i].outerHTML;

                    console.log(returnString);
                }
            };
        }]);
    </script>

HTML:

<html ng-app="main" compile>
    <body>
        {{3 + 4}}
    </body>
</html>

The issue I am facing is when I use the first console.log(), it displays the compiled data as 7 in the outerHTML property. However, when I try to output all the .outerHTML, it only shows the uncompiled version, {{3 + 4}}

Answer №1

Seems like the problem was related to timing. Allowing time for processing the compiled HTML resolved it.

$timeout(function(){
    var updatedHTML = '';
    for(i=0; i<compiledHTML.length; i++)
        updatedHTML += compiledHTML[i].outerHTML;

    console.log(updatedHTML);
},0);
