I have a third-party component that using jQuery (FineUploader). When a document gets uploaded, it fires an event in javascript/jquery and I need to, at that point, call a function that is inside my Angular component from the jquery code that is outside my Angular component.
The angular button works as expected but I can't get the jQuery button to call the function successfully.
Here's my plunker example code
HTML Page
<!DOCTYPE html>
<html>
<head>
<script data-require="angular.js@1.5.8" data-semver="1.5.8" src="https://code.angularjs.org/1.5.8/angular.js"></script>
<script data-require="jquery@1.11.3" data-semver="1.11.3" src="https://code.jquery.com/jquery-1.11.3.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
<script>
function widgetController() {
var model = this;
model.addWidget = function(text) {
alert(text);
}
}
var app = angular.module("app", []);
app.component("widget", {
templateUrl: "template.html",
controllerAs: "model",
controller: [widgetController]
});
</script>
</head>
<body>
<div ng-app="app">
<widget></widget>
</div>
</body>
</html>
Template Page
<center>
<p>The jQuery button below is a representing a third-party component that can't be altered and uses jquery events.</p>
<button id="addAngular" ng-click='model.addWidget("ANGULAR WORKED!!")'>Add widget using Angular</button>
<button id="addJquery">Add widget using jQuery</button>
</center>
<script>
$(function() {
//This is mocking up an event from the third-party component.
$("#addJquery").on("click", function(){
model.addWidget("JQUERY WORKED!!"); //I need to be able to call the Angular function from jQuery
});
});
</script>
I think this may have done the trick but I'm not sure if there is a better answer. Please post an alternate solution if there is a better one.
