Can You Retrieve Custom Data Attributes in IE 6 Using JavaScript?

Custom Data Attributes in IE 6

Custom data attributes, introduced in HTML5, allow developers to store arbitrary data on HTML elements without affecting the element's appearance or functionality. However, concerns arise regarding their support in older browsers, such as Internet Explorer (IE) 6.

To clarify, custom data attributes are defined using the "data-*" prefix, followed by a custom attribute name. For example:

<div>

The question is, can we retrieve the value of this custom attribute ("data-geoff") in IE 6 using JavaScript?

Contrary to expectations, IE 6 does indeed support retrieving custom data attributes. However, it requires the use of getAttribute() instead of the more direct dataGeoff property.

For instance, to retrieve the value of the "data-geoff" attribute in IE 6, you would use:

var geoff = document.getElementById("geoff");
alert(geoff.getAttribute("data-geoff"));

It's important to note that this functionality is not specific to HTML5 attributes; IE 6 supports retrieving custom attributes regardless of their namespace.
