这里主要是针对vis的network图进行节点动态添加

 

图用的是vis.js，表单使用的是element-ui

程序运行截图如下：

添加一个节点：

程序结构如下：

关键源码如下：

FormGroup.vue

<template>
  <el-form :model="ruleForm" status-icon :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
    <el-form-item label="id" prop="pass">
      <el-input v-model="ruleForm.pass" autocomplete="off"></el-input>
    </el-form-item>
    <el-form-item label="结点名" prop="checkPass">
      <el-input v-model="ruleForm.checkPass" autocomplete="off"></el-input>
    </el-form-item>
    <el-form-item label="连接到节点ID" prop="age">
      <el-input v-model.number="ruleForm.age"></el-input>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>
      <el-button @click="resetForm('ruleForm')">重置</el-button>
    </el-form-item>
  </el-form>
</template>


<script>
  import {addNode} from 'JS/visTest.js'
  export default {

      let checkAge = (rule, value, callback) => {

      };

      };
      let validatePass2 = (rule, value, callback) => {

      };

    },
    methods: {
      submitForm(formName) {

        addNode(this.ruleForm['pass'], this.ruleForm['checkPass'], this.ruleForm['age']);
      },
      resetForm(formName) {
        this.$refs[formName].resetFields();
      }
    }
  }
