Jay How does that help?Over the past few years, browsers have converged on using document. It's great to have a single widely-supported way to integrate copy and paste into web apps, but this came at a cost: clipboard access is synchronous, and can only read and write to the DOM.

Synchronous copy and paste might seem fine for small bits of text, but there are a number of cases where blocking the page for clipboard transfer leads to a poor experience.

Time consuming sanitization or decoding might be needed before content can be safely pasted. The browser may need to load linked resources from a pasted document. That would block the page while waiting on the disk or network.

Imagine adding permissions into the mix, requiring that the browser block the page while asking the user if an app can access the clipboard.

At the same time, the permissions put in place around document. So, what might a dedicated clipboard API look like if it addressed blocking and permissions problems? It's a replacement for execCommand-based copy and paste that has a well-defined permissions model and doesn't block the page.

This new API also promises see what I did there? To copy text to the clipboard call writeText. Since this API is asynchronous, the writeText function returns a Promise that will be resolved or rejected depending on whether the text I passed is copied successfully:. Similarly, I can write this as an async functionthen await the return of writeText :. Much like copy, you can read text from the clipboard by calling readText and waiting for the returned Promise to resolve with the text:.

There are plans to introduce a new event for detecting clipboard changes, but for now it's best to use the "paste" event. It works nicely with the new asynchronous methods for reading clipboard text:.

Clipboard access has always presented a security concern for browsers. Without proper permissions in place, a page could silently copy all manner of malicious content to a user's clipboard that would produce catastrophic results when pasted. Giving web pages unfettered read access to the clipboard is even more troublesome. Users routinely copy sensitive information like passwords and personal details to the clipboard, which could then be read by any page without the user ever knowing.

As with many new APIs, navigator. To help prevent abuse, clipboard access is only allowed when a page is the active tab. Pages in active tabs can write to the clipboard without requesting permission, but reading from the clipboard always requires permission.

To make things easier, two new permissions for copy and paste have been added to the Permissions API. The clipboard-write permission is granted automatically to pages when they are the active tab.

The clipboard-read permission must be requested, which you can do by trying to read data from the clipboard.Welcome to the third of my Vue quick shots. Be sure to check out my first and second entries.

I'll be posting a quick Vue. Today's entry is an example of how to add "Copy to Clipboard" functionality for a site. You see this fairly often in developer portals where keys or tokens are shared with developers for their code.

A little bit of JavaScript tied to a button or some other UI is added to make it easier to copy the value. Today's tip will show one way of adding this feature.

An open letter to the friend who hurt me

This is a newer way of accessing the clipboard see this excellent StackOverflow post for a look at other methods that is supported in everything but Internet Explorer and Safari.

Alright, so how can we add a way to copy those values to the clipboard? I'm going to use a simple button that looks like so:.

Interact with the clipboard

The v-if portion will handle hiding or showing the button based on if the browser supports the API. The click handler will pass the value to be copied. I can add it to the HTML like so:. I first added a boolean value for canCopy that will handle the toggle for showing the buttons. I then use created to check if the API exists. Finally I added the copy method.

The clipboard API is an asynchronous one so I wait for it to finish and then alert the user. Let me just say that I am not a fan of using alert like this. The API runs so darn quick I think you could skip this part completely, but technically it's possible someone could click and try to paste at lightning speed and not get what they expect.

I also think you could do the notification a bit nicer than the alert. You could add some text by the button or someplace else in the UI.

Many UI frameworks support a "toast" event that will show a message that automatically dismisses. That would be a great option as well. So before I wrap this quick tip, let me point out this functionality could be done a bit nicer as a component or custom directive.

Cut and Copy Commands

You can even buy me a coffee! Let's begin with a simple application.IE10 and above added support for the 'cut' and 'copy' commands through the Document. As of Chrome version 43, these commands are also supported in Chrome.

copy to clipboard devtools

Any text selected in the browser when one of these commands is executed will be cut or copied to the user's clipboard. This lets you offer the user a simple way to select a portion of text and copy it to the clipboard.

This becomes extremely useful when you combine it with the Selection API to programmatically select text to determine what is copied to the clipboard, which we'll be looking at in more detail later on in this article. For example's sake, let's add a button which copies an email address to the user's clipboard. We add the email address in our HTML with a button to initiate the copying when it's clicked:.

Then in our JavaScript, we want to add a click event handler to our button in which we select the email address text from the js-emaillink anchor, execute a copy command so that the email address is in the user's clipboard and then we deselect the email address so the user doesn't see the selection occur. What we are doing here is using a method of the Selection APIwindow. After calling document. If you wanted to confirm everything worked as expected you can examine the response of document.

We wrap execCommand in a try and catch since the 'cut' and 'copy' commands can throw an error in a few scenarios. The 'cut' command can be used for text fields where you want to remove the text content and make it accessible via the clipboard. Ahead of calling document. In our example above we could set the button disabled state based on support like so:. The difference between document. This is useful in scenarios where you aren't setting the selection of text programmatically and want to ensure the command will do as expected, otherwise present a message to the user.

You can then use the copy function to copy temp1 as a string representation to the clipboard.

The Document. The Clipboard API provides asynchronous access to read and write the clipboard contents directly. For example, to read text from the clipboard:.

This requests the contents of the clipboard and, when the response is received stores the clipboard text into an element's innerText. Note: The asynchronous Clipboard API methods are a recent addition to the specification, and may not be fully implemented to the specification in all browsers.

Be sure to review the compatibility tables for each method before using them, to ensure that support is broad enough for your needs.

Copy to clipboard with Javascript

There are two ways to write to the clipboard. The document. These commands can be used without any special permission if you are using them in a short-lived event handler for a user action for example, a click handler. To make the "copy" button copy the contents of the element is used to create interactive controls for web-based forms in order to accept data from the user; a wide variety of types of input data and control widgets are available, depending on the device and user agent.

Because the execCommand call is inside a click event handler, you don't need any special permissions here. Depending on the browser, this may not work. On Firefox, it will not work, and you'll see a message like this in your console:. To enable this use case, you need to ask for the "clipboardWrite" permission. So: "clipboardWrite" enables you to write to the clipboard outside a short-lived event handler for a user action.

The Clipboard API adds greater flexibility, in that you aren't limited to simply copying the current selection into the clipboard, but can directly specify what information to place into the clipboard. Using the API requires that you have the permission "clipboardRead" or "clipboardWrite" in your manifest.

For page scripts, the Permissions API's "clipboard-write" permission is needed. You can check for that permission using navigator. Note : The clipboard-write permission name is not currently supported in Firefox — only Chromium browsers.

The clipboard and other APIs involved here are evolving rapidly, so there are variations among browsers in how they work. The execCommand method provides the "paste" command, which lets you paste the current clipboard contents at the insertion point in an editable control.

First, you will need to have the "clipboardRead" permission established for your extension. This is the case even if you're using the "paste" command from within a user-generated event handler such as click or keypress. To set the content of the element represents a multi-line plain-text editing control, useful when you want to allow users to enter a sizeable amount of free-form text, for example a comment on a review or feedback form.

The Clipboard API's navigator. This lets you access the data in the clipboard without simply pasting it into an editable element. Once you have the "clipboard-read" permission from the Permissions APIyou can read from the clipboard easily:.

This snippet of code fetches the text from the clipboard and replaces the current contents of the element with the ID "outbox" with that text. Firefox supports the "clipboardRead" permission from version 54, but only supports pasting into elements in content editable modewhich for content scripts only works with a element represents a multi-line plain-text editing control, useful when you want to allow users to enter a sizeable amount of free-form text, for example a comment on a review or feedback form.
