element——switch接口成功后赋值打开开关

应用场景

基本用法使用v-model双向绑定值,进行开关控制

在这里插入图片描述

例子1:需求:

**点击switch,出弹窗,点击弹窗保存按钮调接口成功后再赋值(row.orderButtonValue=“1”)打开switch开的状态变颜色。
在vue 中使用 :value动态的绑定值。
(在Vue中,冒号(:)被称为v-bind指令的缩写。v-bind指令是Vue中非常强大的一个指令,它用于动态绑定数据到HTML标签的属性中。简而言之,冒号就是v-bind指令的语法糖。
说白了,冒号是用来告诉Vue,我要绑定数据到这个属性里,属性的名称就是冒号后面的部分)
**

 <el-table-column prop="orderButtonValue" label="指令" min-width="100" align="center">
        <template slot-scope="scope">
          <el-switch
            v-show="scope.row.orderButton == 1"
            @change="changeClick(scope.row, scope.$index)"
            :value="scope.row.orderButtonValue"
            active-value="1"//打开为 字符串1
            inactive-value="0"//关闭 字符串0
            active-color="#67C8FF"
            inactive-color="#CCCCCC"
            >{{ scope.row.orderButtonValue }}
