Using JavaScript Code with HTML Canvas Pages

Topics:

Although the HTML canvas is fully integrated with JavaScript, it is suggested that you do not create custom JavaScript that manipulates the HTML canvas generated controls, as cannot support such custom JavaScript code. Additionally, there is no guarantee that the JavaScript code will work correctly in future releases.
