HTML and JavaScript

eBay does not permit the use of several types of HTML and JavaScript functions in member listings, Stores pages, About Me pages, or Want-It-Now ads.

Any attempts to disguise the intention or function of the source code (HTML or JavaScript) of your listing are in violation of eBay policy. This includes, but is not limited to:

the use of unescape functions in JavaScript
items that split HTML or other JavaScript tags with the express purpose of hiding the tags within the source code of the listings’s HTML or script

Users may not manipulate or edit any areas outside of the areas designated for member content.

Additionally, on the German site (eBay.de), the use of JavaScript functions is further limited. Refer to the Additional Information section below for more information.

Violations of this policy may result in a range of actions, including:

Listing cancellation
Limits on account privileges
Account suspension
Forfeit of eBay fees on cancelled listings
Loss of PowerSeller status

Some Examples

Not permitted

HTML or JavaScript used to drop or read a cookie on any eBay page
HTML or JavaScript that redirects the user from eBay to another page (such as the "replace" script)
HTML or JavaScript that automatically calls remote scripts and pages (such as JavaScript includes or iframes)
HTML or JavaScript that changes registry entries, or otherwise writes to another's computer hard drive
HTML or JavaScript that creates automatic "pop-ups" (exception - links that open in a new window when clicked on)
HTML or JavaScript that automatically posts to scripts in eBay
HTML or JavaScript that automatically loads any binary program on another's computer (exception - Flash content)
HTML or JavaScript that automatically overwrites any area on the listing outside of the item description area
Manipulation of areas outside the listing description, including changing fonts, colors, backgrounds, etc. in areas such as eBay headers, footers, etc.

Additional Information

Attempts to use the disabled scripts will return a very specific error message that begins: "Disallowed JavaScript/HTML Syntax". Members will be prevented from listing the item or will be disabled at run-time. Any other JavaScript error indicates a separate issue and is not related to the disabling of these scripts.

Why does eBay have this policy?

Some HTML or JavaScript functions can be used for malicious purposes. To maximize the trust and safety of the eBay marketplace and community, eBay does not permit the use of HTML or JavaScript functions specified in the “Examples” section.
