Vue中点击切换按钮功能之点启用后按钮变为禁用

实现:

三步:在template中设置2个按钮,通过v-if ,v-show来控制;data中设置按钮的默认值;methods中控制点击按钮切换效果。

<template>
  <el-table
    :data="tableData"
    border
    style="width: 100%">
    <el-table-column
      fixed
      prop="date"
      label="日期"
      width="200">
    </el-table-column>
     <el-table-column
      prop="state"
      label="状态"
      width="150">
    </el-table-column>
    <el-table-column
      prop="name"
      label="姓名"
      width="120">
      <template slot-scope="scope">
            <el-input placeholder="请输入内容" v-show="scope.row.show" v-model="scope.row.姓名">  
            </el-input>
            <span v-show="!scope.row.show">{{scope.row.姓名}}
            </span>
        </template>
    </el-table-column>
    <el-table-column
      prop="province"
      label="省份"
      width="120">
    </el-table-column>
    <el-table-column
      prop="city"
      label="市区"
      width="120">
    </el-table-column>
    <el-table-column
      prop="address"
      label="地址"
      width="300"
       :show-overflow-tooltip="true" >
    </el-table-column>
    <el-table-column
      prop="zip"
      label="邮编"
      width="120">
    </el-table-column>
    <el-table-column
      fixed="right"
      label="操作"
      width="300">
      <template slot-scope="scope">
        <el-button @click="handleClick(scope.row)" type="text" size="small">查看</el-button>
        <el-button @click="scope.row.show =true" type="text" size="small">编辑</el-button>
        <el-button @click="scope.row.show =false" type="text" size="small">保存</el-button>
        <el-button @click="changeStatus" type="text" size="small" v-if="btnStatus == 0">启用</el-button>
        <el-button @click="changeStatus" type="text" size="small" v-show="btnStatus == 1">禁用</el-button>
        
      </template>
      
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    methods: {
      handleClick(row) {
        console.log(row);
      },
      changeStatus(){
                this.btnStatus = this.btnStatus === 0 ? 1 : 0;
            }
    },

    data() {
      return {
          btnStatus: 0,
        tableData: [{
          date: '2016-05-02',
          
          name: '王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎王小虎',
          province: '上海',
          city: '普陀区',
          address: '上海市普陀区金沙江路 1518 弄上海市普陀区金沙江路 1518 弄',
          zip: 200333,
          show:true
        }, {
          date: '2016-05-04',
          
          name: '王小虎',
          province: '上海',
          city: '普陀区',
          address: '上海市普陀区金沙江路 1517 弄',
          zip: 200333,
          show:true
        }]
      }
    }
}
</script>

另外,注意下,data中,按钮的默认值要放在data下,图1。

不能放在table中,否则会按钮显示不出来,且会报错,图2:Property or method "btnStatus" is not defined on the instance but referenced during render.

这个报错原因是:在template里面或者在方法里面使用了 “btnStatus” ,但是在data里面没有定义。
