Based on answers here, I have been trying to wrap a jQuery plugin (addtocalendar) in an angular directive. I am using ui-router and previously the plugin would work, but if I navigated away from this child to state to another, the addtocalendar button would disappear entirely.
Now, with the plugin wrapped in a directive, if I navigate away to a different child state and then come back, I am able to see the button, however, I get an error from the plugin that I have specified an invalid date. It seems that the data I am feeding the plugin from Angular gets run once and then is never fed to the plugin again.
Is there a workaround for this?
Here is my HTML:
// works fine on first page load
<div addtocalendartest> // angular directive
<div class="addtocalendar"> //jQuery plugin
<div class="arrow-up"></div>
<var class="atc_event">
<var bind-once class="atc_date_start">{{event.startDate | date:'yyyy-MM-dd HH:mm:ss'}}</var>
<var bind-once class="atc_date_end">{{event.endDate | date:'yyyy-MM-dd HH:mm:ss'}}</var>
<var bind-once class="atc_timezone">America/New_York</var>
<var bind-once class="atc_title">{{event.description}}</var>
<var bind-once class="atc_description">{{event.Synopsis | characters: 200 :false }}</var>
<var bind-once class="atc_location">_</var>
</var>
</div>
</div>
And here is the directive I created that contains the plugin logic:
'use strict';
angular.module('myApp')
.directive('addtocalendartest', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
//run jQuery scripts
var w = window;
var d = document;
(function(w, d) {
var atc_url = "//addtocalendar.com/atc/",
atc_version = "1.5",
b = d.documentElement;
if (!Array.indexOf) {
Array.prototype.indexOf = function(e) {

if (this[t] == e) {
return t
}
}
return -1
}
}
if (!Array.prototype.map) {
Array.prototype.map = function(e) {
var t = [];
for (var n = 0, r = this.length; n < r; n++) {
t.push(e(this[n]))
}
return t
}
}

};

var ready = function(e, t) {

if (!n) {

n = true;

}

} else {

e.onload = function(e) {

u()
}
}
}
}
function f() {
if (n) return;

return

UPDATE/ANSWER Thanks to @charlietfl, the answer is to include $timeout so that Angular can load before the jQuery plugin, e.g:
'use strict';
angular.module('myApp')
.directive('addtocalendartest', function($timeout) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
$timeout(function(){
// jQuery plugin logic goes here
}, 5000);
}
};
});
