JavaScript policy

If you intend to sell on one or more of eBay's international sites, you will need to accept, and we encourage you to carefully review, the User Agreement, policies, and other requirements of that site. You can continue to reach out to the relevant customer service teams on the respective eBay site of your listing or transaction, as may be applicable to the nature of your query.

Policy overview

Active content such as JavaScript, Flash, plug-ins, and form actions are no longer displayed in listings. If you include active content in your listings then they may not look as expected and buyer experience may be impaired.

Some forms of active content that can be used maliciously are still not allowed in listings or other eBay pages. You also aren't allowed to use Javacript to manipulate the standard functions of eBay listings, eBay Store pages, or your profile. For details on what is and isn't allowed on the site, see the guidelines below.

Any attempt to disguise the intention or function of a listing's source code when using JavaScript is a violation of eBay policy. Sellers may not manipulate or edit anything outside of the areas designated for member content.

Make sure your listing follows these guidelines. If it doesn't, it may be removed, and you may be subject to a range of other actions, including limits of your buying and selling privileges and suspension of your account.

What are the guidelines

Not allowed 

Not allowed

You can't use JavaScript that:

  • Calls remote scripts and pages automatically

  • Changes registry entries or otherwise writes to another person's computer hard drive.

  • Creates automatic pop-ups except for links that open in a new window when clicked on.

  • Is used to drop or read a cookie on any eBay page.

  • Loads any binary program on another person's computer automatically.

  • Launches a song or video when a listing is opened.

  • Overwrites any area in the listing outside of the item description area.

  • Manipulates areas outside the listing description, including changing fonts, colors, and backgrounds in areas such as eBay headers and footers.

  • Posts to scripts on eBay automatically.

  • Redirects the user from eBay to another web page, such as using the "replace" script.

 

If you try to use scripts that we disable, you'll get an error message that says "Disallowed JavaScript/HTML Syntax". This means you can't list the item, or the script will be disabled at run-time. Any other error message indicates a separate issue and isn't related to disabling HTML or JavaScript code.

 

To help keep our website working the way we designed it to, we don't allow using scripts that manipulate or change the way the site and its features operate, and we don’t render active content.
