思维导图?感觉很复杂的样子,这种很牛p的东西应该不是我三两天就能手写搞定的,于是我github
转了一圈,果然不出我所料,对比了几个插件以后我是先选择了 vue3-mindmap 简单易用。既然好用那就直接npm install
到项目里使用就完了,可是不知道是我使用的方式方法不对还是咋的,很多参数都不生效。于是发现了更好的思维到图库 simple-mind-map ,最终也是和它长相厮守。
1.一个 js 思维导图库,不依赖任何框架,可以使用它来快速完成 Web 思维导图产品的开发。
开发文档:https://wanglin2.github.io/mind-map-docs/
2.一个 Web 思维导图,基于思维导图库、Vue2.x、ElementUI 开发,可以操作电脑本地文件,可以当做一个在线版思维导图应用使用,也可以自部署和二次开发。
在线地址:https://wanglin2.github.io/mind-map/
使用npm安装
npm install simple-mind-map
提供一个宽高不为 0 的容器元素
<div class="mindMapContainer" ref="mindMapContainerRef"></div>
// 样式
.mindMapContainer {
margin: 0;
padding: 0;
width: 100%;
height: calc(100vh - 190px); // 按自己需求修改
}
然后创建一个实例(官方是vue2例子,我使用的是vue3,所以使用方式略微不同,需要手动注册组件),代码如下:
import MindMap from 'simple-mind-map'
import MiniMap from 'simple-mind-map/src/plugins/MiniMap.js'
import Watermark from 'simple-mind-map/src/plugins/Watermark.js'
import KeyboardNavigation from 'simple-mind-map/src/plugins/KeyboardNavigation.js'
import ExportPDF from 'simple-mind-map/src/plugins/ExportPDF.js'
import ExportXMind from 'simple-mind-map/src/plugins/ExportXMind.js'
import Export from 'simple-mind-map/src/plugins/Export.js'
import Drag from 'simple-mind-map/src/plugins/Drag.js'
import Select from 'simple-mind-map/src/plugins/Select.js'
import RichText from 'simple-mind-map/src/plugins/RichText.js'
import AssociativeLine from 'simple-mind-map/src/plugins/AssociativeLine.js'
import TouchEvent from 'simple-mind-map/src/plugins/TouchEvent.js'
import NodeImgAdjust from 'simple-mind-map/src/plugins/NodeImgAdjust.js'
import SearchPlugin from 'simple-mind-map/src/plugins/Search.js'
import Painter from 'simple-mind-map/src/plugins/Painter.js'
import ScrollbarPlugin from 'simple-mind-map/src/plugins/Scrollbar.js'
import Formula from 'simple-mind-map/src/plugins/Formula.js'
import Cooperate from 'simple-mind-map/src/plugins/Cooperate.js'
// 注册插件
MindMap.usePlugin(MiniMap)
.usePlugin(Watermark)
.usePlugin(Drag)
.usePlugin(KeyboardNavigation)
.usePlugin(ExportPDF)
.usePlugin(ExportXMind)
.usePlugin(Export)
.usePlugin(Select)
.usePlugin(AssociativeLine)
.usePlugin(NodeImgAdjust)
.usePlugin(TouchEvent)
.usePlugin(SearchPlugin)
.usePlugin(Painter)
.usePlugin(Formula)
const mindMapContainerRef = ref()
let mindMap = null;
const mindData = {
"data": {
"text": "Root Node",
},
"children": [
{
"data": {
"text": "Child Node 1",
"image": "",
"imageTitle": "",
"hyperlink": "",
"note": ""
},
"children": []
},
{
"data": {
"text": "Child Node 2",
"image": "",
"imageTitle": "",
"hyperlink": "",
"note": ""
},
"children": []
}
]
};
async function init() {
mindMap = new MindMap({
el: mindMapContainerRef.value,
data: mindData
});
}
onMounted( async () => {
init()
})
根据以上使用步骤,得到的效果如下图:
Tab键
可新增子节点。怎样让它更丰富一点呢!再往下瞅瞅。更多功能实现,可以根据需求参考下 官方开发文档 进行开发。
2.1 右键点击节点可弹出操作框
2.1.1 弹出的元素
<!-- 右键菜单 -->
<div v-if="showContextMenu"
class="context-menu"
:style="{ top: `${menuPosition.y}px`, left: `${menuPosition.x}px` }"
>
<ul>
<li>添加子节点</li>
<li>添加同级节点</li>
<li>删除节点</li>
<li>复制节点</li>
<li>粘贴节点</li>
</ul>
</div>
2.1.2 属性设置
// 当前右键点击的类型
const type = ref('')
// 如果点击的节点,那么代表被点击的节点
const currentNode = shallowRef(null)
// 是否显示菜单
const showContextMenu = ref(false);
// 菜单显示的位置
const menuPosition = ref({ x: 0, y: 0 });
2.1.2 节点右击事件
mindMap.on('node_contextmenu', (e, node) => {
if (e.which == 3) {
menuPosition.value = { x: e.clientX +10, y: e.clientY+10 };
showContextMenu.value = true;
currentNode.value = node
}
})
2.1.3 css样式
.top-menu-fixed{
position: fixed;
top: 100px;
left: 50%;
width: 180px;
z-index: 1000;
display: flex;
justify-content: space-around;
background-color: #fff;
padding: 10px 20px;
border-radius: 6px;
box-shadow: 0 2px 16px 0 rgba(0, 0, 0, .06);
border: 1px solid rgba(0, 0, 0, .06);
margin-right: 20px;
.top-menu-item{
width: 50px;
text-align: center;
border: 1px solid rgba(0, 0, 0, .06);
cursor: pointer;
padding: 3px 0px;
border-radius: 5px;
.top-menu-item--text{
font-size: 14px;
}
}
}
.context-menu {
position: fixed;
background-color: white;
border: 1px solid #ccc;
box-shadow: 0px 2px 10px rgba(0, 0, 0, 0.1);
z-index: 1000;
padding: 10px;
border-radius: 4px;
}
.context-menu ul {
list-style: none;
padding: 0;
margin: 0;
}
.context-menu li {
padding: 8px 12px;
cursor: pointer;
}
.context-menu li:hover {
background-color: #f0f0f0;
}

showContextMenu.value = false; // 关闭菜单
};
// 添加同级节点
const addSameNode = () => {
if (mindMap) {
mindMap.execCommand('INSERT_NODE')
}
showContextMenu.value = false; // 关闭菜单
};
// 删除节点
const removeNode = () => {
if (mindMap && currentNode.value) {
mindMap.execCommand('REMOVE_NODE')
}
showContextMenu.value = false; // 关闭菜单
};
// 复制节点
const copyNode = () => {
if (mindMap && currentNode.value) {
mindMap.renderer.copy()
}
showContextMenu.value = false; // 关闭菜单
};
// 粘贴节点
const pasteNode = () => {
if (mindMap && currentNode.value) {
mindMap.renderer.paste()
}
showContextMenu.value = false; // 关闭菜单
};
// 导出为图片
const exportMindMap = () => {
if (mindMap) {
mindMap.export('png', true, '底格里斯任务中心图')
}
};
