“Object doesn’t support property or method ‘find'” error when using Microsoft Bot WebChat in IE11

This post has been republished via RSS; it originally appeared at: IIS Support Blog articles.

For old browser, such as IE 11. We will need to use

<script src="https://cdn.botframework.com/botframework-webchat/latest/botchat-es5.js"></script>

Instead of

<script src="https://cdn.botframework.com/botframework-webchat/latest/botchat.js"></script>

in the web page that hosts the WebChat.


And we must also include

    <link href="https://cdn.botframework.com/botframework-webchat/latest/botchat.css" rel="stylesheet" />

in the same web page that hosts the WebChat.


The issue was documented at this GitHub issue.
