How to Emulate `pointer-events:none` in Internet Explorer?

Emulating Pointer-Events:none in Internet Explorer

In the realm of web development, the pointer-events:none CSS property has become indispensable for creating interactive overlays that allow users to interact with underlying elements. However, Internet Explorer poses a challenge, as it does not recognize pointer-events:none.

Problem Statement

Developers seeking to enhance charts with gradient PNG overlays face a dilemma in Internet Explorer. The use of pointer-events:none to preserve chart interactivity conflicts with the browser's lack of support for this property. As a result, users on IE cannot simultaneously enjoy enhanced chart design and interact with the charts.

Solution

Although pointer-events:none is not recognized for general elements in IE, it is supported for SVG elements. This limitation stems from the specification defining pointer events only for SVG elements.

To implement a pointer-events:none-like behavior in IE, consider wrapping your existing elements in an SVG element. For this, you can utilize the wrap method provided by the jQuery library.

Code Example

CSS:

#tryToClickMe {
  pointer-events: none;
  width: 400px;
  height: 400px;
  background-color: red;
}

HTML:

<svg>

Additional Considerations

If you need to access both overlying and underlying objects, IE provides the document.msElementsFromPoint method. This method returns an array of all layers at a specified point.

By understanding this quirk of Internet Explorer, developers can overcome this challenge and enhance the user experience in their web applications for all users, regardless of their browser preferences.
