How to use Vue and jsmind to create customizable map node styles and connection line styles?

Map is a tool that organizes information in a tree structure. It can help us better organize and display our thinking. Vue is a popular JavaScript framework, and jsmind is a famous JavaScript-based mapping library. Combining Vue and jsmind, we can easily create a customized mapping system. This article will introduce how to use Vue and jsmind to create customizable map node styles and connection line styles, and provide code examples for reference.

First, we need to introduce the jsmind library into the Vue project. You can install jsmind through npm, or directly download the jsmind.js file locally and then introduce the file into the Vue component. In this example, we will introduce jsmind by importing the jsmind.js file.

npm install jsmind

In the Vue component, we can use jsmind's API to create a simple map. For convenience, we can initialize jsmind in Vue's created life cycle hook and use a div element as the map container. The following is a simple Vue component example:

<template>
  <div ref="mindContainer"></div>
</template>

<script>
import jsMind from 'jsmind';

export default {
  name: 'MindMap',
  created() {
    const options = {}; // 在此处设置导图的选项
    const mind = jsMind.show(this.$refs.mindContainer, options);

    const exampleData = { /* 导图的数据结构 */ };
    mind.show(exampleData);
  },
};
</script>

In the above example, we use the jsMind.show() method to create a map instance and mount it to Vue In the mindContainer container of the component. Next, we can display the map content by passing a data object to the jsMind.show() method.

So, how to customize the map node style? jsmind provides some APIs for customizing map node styles. For example, we can use the mind.set_node_style() method to set the style of a specified node. The following is a sample code:

mind.set_node_style('node_id', {
  'background-color': 'red',
  'color': 'white',
});

The above code sets the background color of the specified node to red and the font color to white. You can customize more style attributes according to your needs.

In addition, for the customization of the connection line style, we can use the mind.set_line_color() method, which can specify the color for the connection line. The following is a sample code:

mind.set_line_color('line_id', 'red');

The above code sets the color of the specified connection line to red. In addition to the color, we can also set the thickness, style and other properties of the connection line.

In addition to the above style customization methods, jsmind also provides some other APIs and options to handle map interaction, layout and other needs. You can view the official documentation of jsmind to learn more about the functions of jsmind.

To sum up, by combining Vue and jsmind, we can easily create a customizable mapping system. With the API and options provided by jsmind, we can customize the style of map nodes and connecting lines to meet different needs. I hope this article can help you quickly get started using Vue and jsmind to create and customize your own mapping system.
