clipboard.js is a plug-in that copies text to the clipboard without flash. This article mainly introduces you to the basic usage of clipboard.js. I hope it can help you.

1 Introducing the plug-in

<script src="js/clipboard.min.js"></script>

2 Basic usage

First you need to instantiate it by passing a DOM selector, HTML element or HTML element list.

new Clipboard(&#39;.btn&#39;);

1 Use one element as a trigger to copy the text of another element. The data-clipboard-target attribute needs to be followed by the attribute selector

<!-- Target -->
<input id="foo" value="https://github.com/zenorocha/clipboard.js.git">
<!-- Trigger -->
<button class="btn" data-clipboard-target="#foo">
</button>

In addition, there are Another attribute, data-clipboard-action attribute, is used to specify whether copy or cut operation is required. The default is copy. The cut operation only works on or elements.

<!-- Target -->
<textarea id="bar">Mussum ipsum cacilds...</textarea>
<!-- Trigger -->
<button class="btn" data-clipboard-action="cut" data-clipboard-target="#bar">
    Cut to clipboard
</button>

2 Copy text from the attribute. You don’t need another element as a trigger. You can use the data-clipboard-text attribute and put the text that needs to be copied at the end.

<button class="btn" data-clipboard-text="Just because you can doesn&#39;t mean you should — clipboard.js">
    Copy to clipboard
</button>

3 Others Description

1 Check whether clipboard.js supports Clipboard.isSupported() by running it. If it returns true, it can be used.
2 Show some user feedback or capture the selection after copy/cut operations. Operation, text, trigger element

var clipboard = new Clipboard(&#39;.btn&#39;);
    clipboard.on('success', function(e) {
        console.info('Action:', e.action);
        console.info('Text:', e.text);
        console.info('Trigger:', e.trigger);
        e.clearSelection();
    });
    clipboard.on('error', function(e) {
        console.error('Action:', e.action);
        console.error('Trigger:', e.trigger);
    });

3 This plug-in uses event delegation to trigger, so it greatly reduces operations on the dom.

4 Advanced usage

If you don’t want to modify your HTML, then you can use a very convenient command API. All you need to do is declare a function, write the operation you want, and return a value. Below is an example of returning different values for triggers with different IDs. For specific usage methods, please see https://clipboardjs.com

<body>
    <input id="foo" value="https://github.com/zenorocha/clipboard.js.git">
    <!-- Trigger -->
    <button id=&#39;foo_1&#39; class="btn" data-clipboard-target="#foo">
    </button>
</body>
<script>
    new Clipboard(&#39;.btn&#39;, {
        text: function(trigger) {
            if(trigger.getAttribute(&#39;id&#39;)==&#39;foo_1&#39;){
                return 1;
            }else{
                return 2;
            }
        }
    });
</script>

From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
