Question

我正在尝试将particles.js调整为以下示例中的Vue.js组件： https://codepen.io/MichaelVanDenBerg/pen/WpXGRm

但是，使用下面的代码时，我在控制台中收到以下错误消息：

[Vue警告]：挂钩错误：“TypeError：this.particles不是函数“

如何在下面的代码中修复它？

模板：

</template>
    <div>
        <div id="particles-js"></div>
    </div>
</template>

脚本：

<script>
import particles from 'particles.js'
export default {
    mounted() {
        this.initParticles()
    },
    methods: {
        initParticles () {
            particles("particles-js", {

CSS：

<style scoped>
#particles-js {
    position: absolute;
    width: 100%;
    height: 100%;
    background: #00356B;
}
</style>

Answer 1

particles.js package不会导出任何内容，而是导出sets window.particlesJS。

要使用此软件包，只需在脚本中导入它，然后调用particlesJS()，如下所示。（您的代码很接近，但错误地使用了particles()。）

import 'particle.js'
export default {
  // ...
  methods: {
    initParticles() {
      window.particlesJS("particles-js", {/* ... */})
    }
  }
}

Particles.js进入Vue组件
