Detailed explanation of the Vue.compile function and how to implement rendering dynamic templates

Vue.js is a popular JavaScript framework that is widely used to build user interfaces. One of its core features is the ability to implement dynamic data binding so that pages can be automatically updated based on changes in data. The Vue.compile function is a relatively rarely used function in Vue.js. It allows us to compile dynamic string templates into rendering functions at runtime, thereby realizing the rendering of dynamic templates.

In this article, we will explain in detail how to use the Vue.compile function, and use a specific example to demonstrate how to render dynamic templates.

Vue.compile function introduction
The Vue.compile function is a compilation function provided by Vue.js, which is used to compile dynamic string templates into rendering functions. It accepts a string parameter, which is a string representation of the dynamic template.
Compile dynamic templates using the Vue.compile function
First, we need to introduce the Vue.compile function in Vue.js:

import Vue from 'vue';

Copy after login

Next, we can use Vue. compile function to compile dynamic string template:

const template = '<div>{{ message }}</div>';

const render = Vue.compile(template).render;

Copy after login

In the above example, we defined a dynamic string template template, which contains a data interpolation syntax bound to the message variable. Then, we use the Vue.compile function to compile the template into a rendering function and assign the rendering function to the variable render.

Rendering dynamic templates
Now, we can use the rendering function render to render the dynamic template and insert it into the page:

new Vue({
  data: {
    message: 'Hello, Vue!'
  },
  render: render
}).$mount('#app');

Copy after login

In the above example, We created a Vue instance through new Vue and set the data attribute to an object containing the message attribute. Then, we assign the rendering function render to the render property of the Vue instance to achieve dynamic template rendering. Finally, use the $mount method to mount the Vue instance to the DOM element with the id app.

Complete example

<!DOCTYPE html>
<html>
<head>
  <title>Vue.compile示例</title>
  <script src="https://cdn.jsdelivr.net/npm/vue@2.6.12/dist/vue.js"></script>
</head>
<body>
  <div id="app"></div>

  <script>
    const template = '<div>{{ message }}</div>';

    const render = Vue.compile(template).render;

    new Vue({
      data: {
        message: 'Hello, Vue!'
      },
      render: render
    }).$mount('#app');
  </script>
</body>
</html>

Copy after login

In the above example, we first introduced the CDN link of the Vue.js framework. Then, we define a dynamic string template template and use the Vue.compile function to compile it into the rendering function render. Next, we created a Vue instance and rendered the dynamic template through render. Finally, use the $mount method to mount the Vue instance to the DOM element with the id app.

Through the above steps, we successfully used the Vue.compile function to realize the rendering of dynamic templates.

Summary:
The Vue.compile function allows us to compile dynamic string templates into rendering functions at runtime, thereby realizing the rendering of dynamic templates. Its usage steps include introducing the Vue.compile function, using the Vue.compile function to compile dynamic templates, and rendering dynamic templates. We can implement the rendering of dynamic templates through the above steps. In actual development, when we need to render templates according to different situations, the Vue.compile function will be very useful.
