<template>
  <div>
    <div style="width: 100%;height: 100px;">
     <!-- 添加会员 -->
    <el-button type="primary" @click="sendmessage" style="margin-top: 30px;float: left; margin-left: 10px;margin-bottom: 25px;"><i class="el-icon-s-promotion">发送</i></el-button>
    <el-button type="primary" style="margin-top: 30px;float: left; margin-left: 5px;margin-bottom: 25px;">√全选</el-button>
    <el-button type="primary" style="margin-top: 30px;float: left; margin-left: 5px;margin-bottom: 25px;">×批量删除</el-button>

    </div>
 
    <!-- 弹出的页面内容 -->
    <el-dialog :visible.sync="getmessage">
      <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
        <el-form-item label="收件人：">
            <!-- 下拉框 -->
          <el-select v-model="value" placeholder="请选择">
            <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value"></el-option>
          </el-select>
        </el-form-item>
        <el-form-item label="">
            <el-input v-model="ruleForm" placeholder="标题信息" style="margin-top: 10px;"></el-input>
        </el-form-item>
        <el-form-item label="">
            <el-card style="height: 610px;">
              <quill-editor v-model="content" ref="myQuillEditor" style="height: 500px;" :options="editorOption">
              </quill-editor>
            </el-card>
        </el-form-item>
        <el-form-item>
            <el-button type="primary" @click="submitForm('ruleForm')" style="float:right">确定</el-button>
        </el-form-item>
    </el-form>
    </el-dialog>

 
    <!-- 表格 -->
    <el-table :data="tableData" style="width: 100%">
      <el-table-column label="">
        <div>
            <input type="checkbox" v-model="use1" id="r1"></input>
        </div>
      </el-table-column>
      <el-table-column label="标题" prop="date">
      </el-table-column>
      <el-table-column label="时间" prop="name">
      </el-table-column>
      <el-table-column label="接受条件" prop="date">
      </el-table-column>
      <el-table-column label="操作">
        <template slot-scope="scope">
          <el-button size="mini" @click="handleEdit(scope.$index, scope.row)">Edit</el-button>
          <el-button size="mini" type="danger" @click="handleDelete(scope.$index, scope.row)">Delete</el-button>
        </template>
      </el-table-column>
    </el-table> 
 
  </div>
</template>
 

script配置

<script>

export default {

  data() {
    
    return {
      //弹框
      getmessage:false

    }
  },
  methods:{
    //弹框
    sendmessage(){
        this.getmessage = true
    } 

  }
  
}
</script>
