The purpose is so you can copy an item and then immediately paste it elsewhere. There isnt any way to access it, and it only holds the most recently copied item. Check the compatibility tables for each method before using it. As noted above, the clipboard is just a temporary holding source for whatever you just copied. In addition, read() and write() are disabled by default and require changing a preference to enable them. Content scripts applied on HTTP sites do not have access to the clipboard object.
Due to both potential security concerns and technical complexities, the process of integrating this API is happening gradually in most browsers.įor example, Firefox does not yet support the "clipboard-read" and "clipboard-write" permissions, so access to the methods that access and change the contents of the clipboard are restricted in other ways.įor WebExtensions, you can request the clipboardRead and clipboardWrite permissions to be able to use clipboard.readText() and clipboard.writeText(). The asynchronous clipboard API is a relatively recent addition, and the process of implementing it in browsers is not yet complete.
