很久之前寫過一篇cytoscape.js基礎篇, 地址是https://blog.csdn.net/dahaiaixiaohai/article/details/89669526. 可以適當的參考一下其內容.
很久之前寫過一篇cytoscape.js初級篇, 地址是https://blog.csdn.net/dahaiaixiaohai/article/details/108862390. 可以適當的參考一下其內容.
很久之前寫過一篇cytoscape.js Cxtmenu圓形選單篇, 地址是https://blog.csdn.net/dahaiaixiaohai/article/details/108867486. 可以適當的參考一下其內容.
本篇章, 正式使用cytoscape.js實作一些簡單的節點操作, 并加上左上角的操作工具列. 所提供的工具列功能有: 放大, 縮小, 自由布局, 方形布局, 圓形布局, 高亮鄰居. 實作這些功能后, 開發者可以自由實作其他功能. 擴展功能將會在后期繼續更新發布.
本文對應的源代碼寄托于github, cytoscape.js進階篇 , 在此感謝github提供的服務.

前言
本實體通過Vue開發測驗, 其他開發方式可以參考本篇章, 適當的修改后使用.
cytoscape依賴參考
- npm : npm install cytoscape --save
- bower : bower install cytoscape
- jspm : jspm install npm:cytoscape
cytoscape擴展依賴參考
- 本篇章主要依賴
cytoscape-avsdf,cytoscape-cola,cytoscape-cose-bilkent組件. 所以務必保證該些組件安裝成功.
npm 布局及擴展依賴參考
# Cytoscape.js的圓形可滑動背景關系擴展選單
npm install cytoscape-cxtmenu --save
# Cytoscape.js的布局方式
npm install cytoscape-avsdf --save
npm install cytoscape-cola --save
npm install cytoscape-cose-bilkent --save
升級Cytoscape組件
- 本篇章是在 cytoscape.js Cxtmenu圓形選單篇 的基礎上繼續完善實作的, 沒有 cytoscape.js Cxtmenu圓形選單篇 準備作業或后面代碼看起來有些吃力的小伙伴們可以先看一下cytoscape.js Cxtmenu圓形選單篇, cytoscape.js初級篇 , 甚至可以先看一下 cytoscape.js基礎篇 .
擴展Cytoscape組件模板容器
- 擴展Cytoscape模板容器后的樣式, 在左上角會多出一組工具列. 該工具列是由組件本身提供, 不需要參考者單獨開發工具列.

重繪布局
- 依賴上述依賴組件:
cytoscape-avsdf,cytoscape-cola,cytoscape-cose-bilkent組件.
/**
* 重繪布局.
* name取值范圍:
* ['grid', 'circle', 'cola', 'avsdf', 'cose-bilkent', ]

*/
refresh({name = 'cola', randomize = false, animate = true} = {}) {
this.$cy.layout({name: name, randomize: randomize, animate: animate,}).run();
},
高亮鄰居
- 高亮的程序: 判斷是否有選擇節點, 多選擇節點, 只取第0個節點.
- 給所有節點添加高亮樣式, 獲取選擇節點去除高亮樣式.
- 添加一次性操作onse(‘click’, () => {}), 取消高亮樣式.
- 異步執行.
/**
* 高亮.
* @param ele 某元素ID
*/
lightOn(ele) {
this.$cy.startBatch();
this.$cy.batch(() => {
this.$cy.elements().addClass("light-off"); //*添加樣式*/

Cytoscape組件的使用
- Cytoscape測驗模板與 cytoscape.js初級篇 的Cytoscape測驗模板幾乎完全一致.
- 唯一差距在: 將添加, 洗掉按鍵下移, 給工具列騰出位置.
創建Cytoscape測驗模板
<template>
<div style="height: 100%; width: 100%; border: 1px solid #00F;">
<div style="position: fixed; left: 20pt; top: 50pt; z-index: 99999;">
<Button size="small" @click="addEles">添加</Button>
<Button size="small" @click="delEles">洗掉</Button>
</div>
<CJS ref="ref_CJS"></CJS>
</div>
</template>
- 樣式如下
Cytoscape組件參考
- 測驗模板參考Cytoscape組件, 并命名為CJS.
<script>
import CJS from './components/cjs';
export default {
name: "Test",
components: {CJS,},
// ......
}
</script>
