Modern copy to clipboard. No Flash. Just 3kb gzipped.
Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework.
That's why clipboard.js exists.
You can get it on npm.
npm install clipboard --save
Or bower, too.
bower install clipboard --save
If you're not into package management, just download a ZIP file.
First, include the script located on the
dist folder or load it from a third-party CDN provider.
Internally, we need to fetch all elements that matches with your selector and attach event listeners for each one. But guess what? If you have hundreds of matches, this operation can consume a lot of memory.
We're living a declarative renaissance, that's why we decided to take advantage of HTML5 data attributes for better usability.
A pretty common use case is to copy content from another element. You can do that by adding a
data-clipboard-target attribute in your trigger element.
The value you include on this attribute needs to match another's element selector.
<!-- Target --><!-- Trigger -->
Additionally, you can define a
data-clipboard-action attribute to specify if you want to either
If you omit this attribute,
copy will be used by default.
<!-- Target -->Mussum ipsum cacilds...<!-- Trigger -->Cut to clipboard
As you may expect, the
cut action only works on
Truth is, you don't even need another element to copy its content from. You can just include a
data-clipboard-text attribute in your trigger element.
<!-- Trigger -->Copy to clipboard
There are cases where you'd like to show some user feedback or capture what has been selected after a copy/cut operation.
That's why we fire custom events such as
error for you to listen and implement your custom logic.
var clipboard = '.btn';clipboard;clipboard;
For a live demonstration, open this site and just your console :)
If you don't want to modify your HTML, there's a pretty handy imperative API for you to use. All you need to do is declare a function, do your thing, and return a value.
For instance, if you want to dynamically set a
target, you'll need to return a Node.
If you want to dynamically set a
text, you'll return a String.
Also, if you are working with single page apps, you may want to manage the lifecycle of the DOM more precisely. Here's how you clean up the events and objects that we create.
var clipboard = '.btn';clipboard;
|42+ ✔||12+ ✔||41+ ✔||9+ ✔||29+ ✔||10+ ✔|
The good news is that clipboard.js gracefully degrades if you need to support older browsers. All you have to do is show a tooltip saying
success event is called and
Press Ctrl+C to copy when
error event is called because the text is already selected.
You can also check if clipboard.js is supported or not by running
Clipboard.isSupported(), that way you can hide copy/cut buttons from the UI.
