How can I get ng-click to function with ng-repeat and ng-bind-html? - angularjs

Question

I am trying to get a ng-click directive to function within an ng-repeat and ng-bind-html. The ng-click code is added to a string of html from data pulled from the server (hence the ng-bind-html). The setup has a controller, a base template that is put onto the page with Drupal, and a partial that is loaded via the template from Drupal.
The controller looks like this at the moment:
var guideListController = angular.module('app')
.controller('guideListController', [
'$scope',
'$sce',
'$compile',
'ViewService',
'ToolKit',
function($scope, $sce, $compile, ViewService, ToolKit) {
// Storage for which rows need more/less links
this.rowIndex = [];
this.showFull = false;
this.showFullClick = function() {
alert('Showfull');
};
this.trustIntro = function(code) {
return $sce.trustAsHtml(code);
};
// Fetch the guide list view from services
var data = ViewService.get({view_endpoint:'guide-service', view_path: 'guide-list'}, function(data) {
//console.log(data);
// Update/process results
for (var row in data.results) {
// Create short intro w/ truncate.js
data.results[row].Intro_short = $sce.trustAsHtml($scope.guideList.getShortIntro(data.results[row], row));
//data.results[row].Intro_short = $scope.guideList.getShortIntro(data.results[row], row);
// Update intro
data.results[row].Introduction = $sce.trustAsHtml($scope.guideList.updateIntro(data.results[row], row));
//data.results[row].Introduction = $scope.guideList.updateIntro(data.results[row], row);
}
$scope.guideList.guides = data.results;
});
// Add a read less anchor tag at the end of the main intro
this.updateIntro = function(row, row_index) {
var intro = row['Introduction'].trim();
if ($scope.guideList.rowIndex[row_index]) { // only apply Less link if needed
var index = intro.length - 1;
var tag = [];
if (intro.charAt(index) === '>') { // we have a tag at the end
index--;
do {
tag.push(intro.charAt(index));
index--;
} while (intro.charAt(index) != '/'); // the closing tag
index--; // we move the index one more for the "<"
tag.reverse(); // Reverse
tag = tag.join('');
}
var inserts = ['div', 'p']; // we insert the Less link here.
if (jQuery.inArray(tag, inserts) >= 0) { // insert into the tag
intro = intro.substr(0, index) + ' <a class="less" ng-click="$parent.guideList.showFull = false">Less</a>' + intro.substr(index);
}
else { // insert at the end of the html
intro = intro + '<a class="less" ng-click="this.showFull = false">Less</a>';
}
}
return intro;
};
// Truncate the long intro into a shorter length blurb
this.getShortIntro = function(row, row_index) {
// Truncate if necc.
var short_intro = jQuery.truncate(row['Introduction'], {
length: 250,
words: true,
ellipsis: '\u2026 <a class="more moreish" attr-ng-click="guideList.showFullClick()">Read on</a>'
});
var more = jQuery('.more', short_intro); // select more link
if (more.length) { // do we have a more link
$scope.guideList.rowIndex[row_index] = true;
}
else { // no more link
$scope.guideList.rowIndex[row_index] = false;
}
$compile(short_intro)($scope);
return short_intro;
};
}]);
As you can see in the ViewService.get() call, data is fetched and then processed. The processing simply involves putting a link at the end of the "Intro" field that is intended to be clickable.
For a while I was having a tough time to even get the ng-click directive to even show (it was being filtered out w/out $sce.trustAsHtml). Now it is there but clicking it has no effect.
The main template (from Drupal) currently looks like:
<div class="guide-listing" ng-controller="guideListController as guideList">
<a ng-click="guideList.showFullClick()">Click me</a>
<div class="guide-teaser"
ng-repeat="guide in guideList.guides"
ng-include src="'/sites/all/themes/ngTheme/ngApp/partials/guide_teaser.html'">
<!-- See guide_teaser.html partial for guide teasers -->
</div>
</div>
The ng-click as placed in the Drupal template above works as expected.
And for the partial that is used in the ng-repeat, it looks like so:
<div ng-controller="guideListController as guideList">
<h2 class="guide-teaser-title">{{guide.node_title}}</h2>
<div class="guide-teaser-intro" ng-bind-html="guide.Introduction" ng-show="guide.showFull">
{{guide.Introduction}}
</div>
<div class="guide-teaser-intro-short" ng-bind-html="guide.Intro_short" ng-show="!guide.showFull">
{{guide.Intro_short}}
</div>
</div>
So far I have only been working on getting the ng-click to work on the short_intro and have had no success so far. Any ideas as to what I am doing wrong would be greatly appreciated!

Ok, So I did get some traction! I used the ngHtmlCompile (http://ngmodules.org/modules/ng-html-compile) directive that was created by https://github.com/francisbouvier (thanks!)
The issue was that the new (dynamic) html wasn't being compiled.
At first it didn't work. I had two issues that prevented it from firing:
A: I stopped using $sce.trustAsHtml. Using this in conjunction with the directive caused the content to disappear!
B: The other issue was one of scope. After I changed the directive such that transclude was set to false it worked just fine!
