如何在 JavaScript 项目中使用 Particle.js？

As the name suggests, the Particle.js library allows us to add particles to specific HTML elements. Additionally, we can change the number of shapes of the particles in the div.

We can add animation or motion to particles using the Particle.js library. Here we will learn to change the shape, color and movement of particles through different examples.

grammar

Users can use the Particle.js library in JavaScript projects according to the following syntax.

tsParticles.load("id", {
   particles: {
      
      // properties for the particles
   }
});

In the above syntax, id represents the id of the div element to which we need to add particles.

Example

In the example below, we are using the Particles.JS library and using the CDN in the

tag. We created the element and assigned the id in the HTML body.

In JavaScript, we added the tsarticles.load() method to load particles. As the first parameter of the load() method, we pass the id of the div element. We pass this object as the second parameter containing the particle properties.

<html>
<head>
   <script src = "https://cdnjs.cloudflare.com/ajax/libs/tsparticles/1.18.11/tsparticles.min.js"> </script>
   <style>
      #tsparticles {
         width: 100%;
         height: 100%;
         background-color: grey;
      }
   </style>
</head>
<body>
   <div id = "tsparticles">
      <h2 id="Using-the-i-particle-js-library-i-in-the-JavaScript-project"> Using the <i> particle.js library </i> in the JavaScript project. </h2>
   </div>
   <script>
      tsParticles.load("tsparticles", {
         particles: {
            number: {
               value: 500
            },
         }
      });
   </script>
</body>
</html>

In the output, the user can observe the particles in the div element.

Example

The following example will add movement and color to particles. Users can use the move attribute to move particles. The "move" property takes the value as an object containing the enabled property with a boolean value.

<html>
<head>
   <script src = "https://cdnjs.cloudflare.com/ajax/libs/tsparticles/1.18.11/tsparticles.min.js"> </script>
   <style>
      #particles {
         width: 100%;
         height: 100%;
         background-color: lightgreen;
      }
   </style>
</head>
<body>
   <div id = "particles"> 
      <h2 id="Using-the-i-particle-js-library-i-in-the-JavaScript-project"> Using the <i> particle.js library </i> in the JavaScript project. </h2>
   </div>
   <script>
      tsParticles.load("particles", {
         particles: {
            number: {
               value: 1000
            },
            move: {
               enable: true
            },
            color: {
               value: "#272701"
            },
         }
      });
   </script>
</body>
</html>

Users can use the color property to change the color of particles that contain this object as a value.

Users can use the following shapes of particles in the Particle.JS library.

"Polygon"
"triangle"
"Circle"
"Edge"/"Square"
"image"/"image"
"Star"
"Character"/"Character"

Example

In the example below, we have added a polygon shape to the particles. Additionally, we changed the size of the particles using the size property. Additionally, we added animation to the particles themselves, increasing and decreasing the size of the particles that users can observe in the output.

<html>
<head>
   <script src = "https://cdnjs.cloudflare.com/ajax/libs/tsparticles/1.18.11/tsparticles.min.js"> </script>
   <style>
      #particles {
         width: 100%;
         height: 100%;
         background-color: lightgreen; 
      }
   </style>
</head>
<body>
   <div id = "particles">
      <h2 id="Using-the-i-particle-js-library-i-in-the-JavaScript-project">Using the <i> particle.js library </i> in the JavaScript project. </h2>
   </div>
   <script>
      tsParticles.load("particles", {
         particles: {
            number: {
               value: 1000
            },
            move: {
               enable: true
            },
            color: {
               value: "#ff0342"
            },

            // adding shape of particles
            shape: {
               type: "polygon",
            },

            // changing the size of elements
            size: {
               value: 8,
               random: true, 
               animation: {
                  enable: true,
                  speed: 40,
                  sync: true
               },
               move: {
                  enable: true,
               },
            }
         }
      });
   </script>
</body>
</html>

What is 'this' in JavaScript?Mar 04, 2025 am 01:15 AM

Core points This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called. When there is no current object, this refers to the global object. In a web browser, it is represented by window. When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object. You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
