I'v been using Jdenticon JavaScript library (https://jdenticon.com/) for my user icons. It should take hash and render it as either SVG or Canvas using something like this:
<svg width="200" height="200" data-jdenticon-hash="ff8adece0631821959f443c9d956fc39">
Fallback text for browsers not supporting inline svg
</svg>
So the problem is that I am trying to render multiple user icons on single page using angular ng-repeat and bind hash inside data-jdenticon-hash. It appears that all data is right where it should be, but Jdenticon is complaining that it doesnt see the binded data. If I add static hash, like "ff8adece0631821959f443c9d956fc39" inside data-jdenticon-hash, it renders all icons the same, but correctly.
Here is my current code:
<div ng-repeat="i in friends" last-element-directive>
<div id="requests" class="col col-md-12 col-sm-12 col-xs-12 tab-pane fade in active" ng-show="user_friends">
<div id="icon" class="col-md-12">
<div class="col-md-1 col-sm-1 col-xs-4">
<svg width="40" height="40" data-jdenticon-hash="{{i.avatar}}"></svg>
</div>
<div class="col-md-3 col-sm-2 col-xs-3">
<h3><a href="/user/?id={{i.username}}" target="_blank">{{i.username}}</a></h3>
</div>
</div>
</div>
</div>
Any help would be appreciated!
I'm not an expert with jdention but just stumbled over this while implementing it for my project. Maybe it helps you:
The problem is that
jdenticon.update
is never called for canvases created dynamically as by Angular. A solution could be to create a directive that is responsible for callingjdenticon.update
when the canvas element is constructed. See this fiddle for an example: https://jsfiddle.net/w5h6msvd/
source is this github issue: https://github.com/dmester/jdenticon/issues/10
Edit: this is how I use it now in my project
import identiconImpl from 'jdenticon';
export default () => ({
restrict: 'A',
link: (scope, elem) => {
identiconImpl.update(elem[0], scope.hashValue);
},
scope: {
hashValue: '<'
}
});
And this is the template:
<svg identicon hash-value="ctrl.hashAndSaltOperatorName()"></svg>
Oh and here the index.js to have all the necessary parts:
export default angular
.module('jdenticonHash', [])
.directive('identicon', identiconDirective);
