Status: RESOLVED DUPLICATE of bug 1351501

(Core :: DOM: Bindings (WebIDL), defect)

Description

[u623779]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce:

In salesforce, add Leaflet (https://leafletjs.com/) as a static resource named "leaflet"

    Create a lightning component that is available for communities.
In the component add the following:

<ltng:require styles="/resource/leaflet/leaflet.css"
        scripts="/resource/leaflet/leaflet.js"
        afterScriptsLoaded="{!c.jsLoaded}" />

In the Component js controller, create a method called jsLoaded:
jsLoaded: function(component, event, helper) {alert("Hello");}

Create a salesforce community and add the component onto a page.
Open that page.



Actual results:

Nothing


Expected results:

An alert with "Hello"
Works in other browsers

Triaging as a Core: JavaScript issue. Please correct if this is not the right component.
