LEADTOOLS HTML5 Browser Support


The LEADTOOLS HTML5 / JavaScript toolkit can be used to develop applications for any web browser that supports HTML5.

The LEADTOOLS HTML5 / JavaScript toolkit supports the following browsers

  • Desktop Browsers
    • Internet Explorer (9 and later)
    • Edge
    • Safari
    • Chrome
    • Firefox
    • Opera
  • Mobile Browsers
    • Internet Explorer 10
    • Safari
    • Chrome
    • Android
    • Firefox Mobile
    • Opera Mobile

Note: Microsoft Internet Explorer browsers versions 8 and earlier have a faulty support ECMA JavaScript Object.defineProperty method. Browsing to an HTML page that includes LEADTOOLS libraries references in the head section will result in an error. The workaround is to insert the following JavaScript script into the head section prior to any LEADTOOLS reference:

JavaScript Example
<!-- Workaround for Internet Explorer 8 and earlier. Must be added before any LEADTOOLS references --> 
<script type="text/javascript"> 
   // check whether HTML5 canvas is supported 
   if (!("HTMLCanvasElement" in window)) { 
      alert('HTML 5 Canvas not supported, redirecting ...'); 
      location.href = "https://www.leadtools.com";  
<!-- LEADTOOLS references --> 
<script type="text/javascript" src="Scripts/Leadtools.js"></script> 
<script type="text/javascript" src="Scripts/Leadtools.Controls.js"></script>
