前言
越来越发现,前端深入好难哦!虐成渣渣了。
需求:前端绘制灵活的关系图(此demo还是简单的,我的需求才跨出一小步)
安装
npm install jointjs
容器,工具栏
<template>
<div id="toolbar">
<button class="btn add-question" :click='addNode'>Add Node</button>
<button class="btn add-answer">Add Answer</button>
<button class="btn preview-dialog">Preview Dialog</button>
<button class="btn code-snippet">Code Snippet</button>
<button class="btn clear">Clear Canvas</button>
<button class="btn load-example">Load Example</button>
</div>
<div id="myholder" @click="click_joint"></div>
</template>
<script>
require('../assets/css/toolbar.css')
import ParamidaPay from "../paramidaPay.js"
import joint from 'jointjs'
import $ from 'jquery' export default {
name: 'App',
data: function () {
return {
active: true
}
},
mounted: function () {
this.inti()
},
methods: {
inti(){
// 先创建joint graph 对象
var graph = new joint.dia.Graph(); //设定容器基本信息
var paper = new joint.dia.Paper({
el: document.getElementById('myholder'),
width: 900,
height: 700,
model: graph,
});
let rect = new joint.shapes.basic.Rect({
position: { x: 100, y: 30 },
size: { width: 100, height: 30 },
attrs: {
rect: { fill: 'rgb(75, 74, 103)' }, text: { text: 'node', fill: 'white' }
}
})
let rect2 = rect.clone(); let rect3 = rect.clone();
rect2.translate(300);
rect3.translate(600); let link = new joint.dia.Link({
source: { id: rect.id },
target: { id: rect2.id }
}) graph.addCells([rect, rect2, rect3,link]);
}
},
addNode(){ }
}
</script>
<style>
#myholder{
width: 900px;
height: 700px;
margin: 0 auto;
margin-top: 25px;
border: 1px solid #d3d3d3;
}
</style>
运行效果
Fannie式总结
是不是有点好看
话不多说,我其实是为了保存代码,最小单元
然后我要接着做下去了
好了,emmmm(调研阶段有更多的坑,我下一篇文章写)
