Vue项目中实现自定义连线图

news 2025/5/10 13:04:42

需求描述

在vue项目中实现由自定义块元素组成的连线图。

效果图

连线图

实现思路

Leader-Line 是一个用于 Web 的轻量级 JavaScript 库，专为创建从一个元素指向另一个元素的引导线而设计。它提供了高度自定义的能力，使得开发者能够轻松地在网页上实现各种指引用例，如表单验证指示、界面导航辅助等。该库支持现代浏览器，且不依赖任何大型框架，保证了其灵活性和性能。
利用Leader-Line组件可以实现把不同dom元素进行连接，且连线及箭头可以灵活自定义。

具体步骤

1、环境版本：

Node版本：16.20.2
Leader-Line版本： 1.0.8

2、使用npm或yarn安装leader-line依赖包

npm install leader-line  或  yarn add leader-line

3、找到装好的依赖包，把leader-line.min.js文件复制到自己的拓展工具类函数文件夹下面
例如放置路径：src\plugins\leader-line.min.js

4、在使用的地方引入leader-line.min.js文件

import LeaderLine from "@/plugins/leader-line.min.js";

5、创建连线
