Uncaught SyntaxError: Unexpected token )

I have an html file using which I am rendering a react component. Here is my html file

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="../../../elements/css/elements.css"/>
    <link rel="shortcut icon" href="http://example.com/myicon.ico"/>
</head>
<body>

<h1>Text Modal Demo</h1>
<p>Styled using the Elements SDK.</p>
<br/>
<div id="app"></div>

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.3.2/react.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.3.2/react-dom.js"></script>

<script src="https://cdn.polyfill.io/v2/polyfill.js?features=CustomEvent,Intl.~locale.en,Intl.~locale.fr"></script>

<script type="text/javascript" src="../../jsfiles/textModal/dist.text-modal.js"></script>
<script type="text/javascript" src="../../jsfiles/textModal/text-modal.js"></script>
</body>
</html>

And here is my text-modal.js file

function init() {

  // Demo eventing API
  document.body.dispatchEvent(new CustomEvent('o.InitTextModal', {
      detail: { elementId: 'app', contentTemplateLarge: true, footerVisible: true, successBtnCallback: () => { console.log('¡¡success button pressed!!') }}
  }
  ));
}
window.onload = init;

When I try to load the html file, I see this error in my console Uncaught SyntaxError: Unexpected token ) at Line 5 text-modal.js which is this line - detail: { elementId: 'app', contentTemplateLarge: true, footerVisible: true, successBtnCallback: () => { console.log('¡¡success button pressed!!') }}

This issue is seen only on IE 11 and Android device. Works fine for iOS


IE11 doesn't support arrow functions. You need to rewrite your javascript:

Before:

 () => { console.log('¡¡success button pressed!!') }

After:

 function() { console.log('¡¡success button pressed!!') }

看起来像IE 11或某些旧版本的Android浏览器不支持箭头语法。


I haven't tried this much but as far as the error looks this thingy here seems it is not supported better use the same old way of creating functions to make sure it is compatible anywhere

successBtnCallback: () => { // Anything else }

hope that helps
