VUE动态生成word的实现

不废话，直接上代码。

前端代码：

<template>
  <Form ref="formValidate" :model="formValidate" :rules="ruleValidate" :label-width="110">
    <FormItem label="项目（全称）：" prop="orgName">
      <Input v-model="formValidate.orgName" placeholder="请输入项目名称"></Input>
    </FormItem>
    <FormItem label="申请人：" prop="applyName" >
      <Input v-model="formValidate.applyName" placeholder="请输入申请人"></Input>
    </FormItem>
    <FormItem label="电话：" prop="applyPhone">
      <Input v-model="formValidate.applyPhone" placeholder="请输入电话"></Input>
    </FormItem>
    <FormItem label="生效日期：" style="float: left">
      <Row>
        <FormItem prop="startDate">
          <DatePicker type="date" format="yyyy-MM-dd" placeholder="请选择生效日期" v-model="formValidate.startData"></DatePicker>
        </FormItem>
      </Row>
    </FormItem>
    <FormItem label="失效日期：">
      <Row>
        <FormItem prop="endDate">
          <DatePicker type="date" format="yyyy-MM-dd" placeholder="请选择失效日期" v-model="formValidate.endData"></DatePicker>
        </FormItem>
      </Row>
    </FormItem>
    <FormItem label="备注：" prop="vmemo">
      <Input v-model="formValidate.vmemo" type="textarea" :autosize="{minRows: 2,maxRows: 5}" placeholder="备注"></Input>
    </FormItem>
    <FormItem>
      <Button type="primary" @click="handleSubmit('formValidate')">生成申请单</Button>
    </FormItem>
  </Form>
</template>
<script>
  import axios from 'axios';
  export default {
    data () {
      return {
        formValidate: {
          orgName: '',
          applyName: '',
          applyPhone: '',
          startDate: '',
          endDate: '',
          vmemo:''
        },
        ruleValidate: {

          ],

          ],
          applyPhone: [
            { required: true, message: '电话不能为空！', trigger: 'change' }
          ],
          startDate: [
            { required: true, type: 'date', message: '请输入license有效期！', trigger: 'change' }
          ],
          endDate: [
            { required: true, type: 'date', message: '请输入license有效期！', trigger: 'change' }
          ],
        }
      }
    },
    methods: {
      handleSubmit (name) {
        this.$refs[name].validate((valid) => {
          if (valid) {
            axios({
              method: 'post',
              url: this.$store.getters.requestNoteUrl,
              data: this.formValidate,
              responseType: 'blob'
            }).then(res => {
              this.download(res.data);
            });
          }
        });
      },
      download (data) {
        if (!data) {
          return
        }
        let url = window.URL.createObjectURL(new Blob([data]))
        let link = document.createElement('a');
        link.style.display = 'none';
        link.href = url;
        link.setAttribute('download', this.formValidate.orgName+'('+ this.formValidate.applyName +')'+'-申请单.doc');
        document.body.appendChild(link);
        link.click();
      }
    }
  }
</script>

补充知识：vue elementui 页面预览导入excel表格数据

html代码：

<el-card class="box-card">
<div slot="header" class="clearfix">
<span>数据预览</span>
</div>
<div class="text item">
<el-table :data="tableData" border highlight-current-row style="width: 100%;">
<el-table-column :label="tableTitle" >
<el-table-column min-width="150" v-for='item tableHeader' :prop="item" :label="item" :key='item'>
</el-table-column>
</el-table-column>
</el-table>
</div>
</el-card>

js代码：

import XLSX from 'xlsx'

data() {
  return {
    tableData: '',
    tableHeader: ''
  }

  document.getElementsByClassName('el-upload__input')[0].setAttribute('accept', '.xlsx, .xls')

    return this.readerData(itemFile)
  }
},
methods: {
