el-cascader获得焦点

el-cascader获得焦点的实现可以通过为el-cascader元素添加focus事件来实现。具体的实现代码如下：

<el-cascader size="large" :options="options" v-model="addOrder.address" @change="handleChange" clearable style="width: 300px;" @blur='addressBlur' @focus='addressFocus'></el-cascader>

在methods中添加addressFocus方法来处理焦点事件：

methods: {
  addressFocus() {
    // 这里可以添加获得焦点后的逻辑处理
  },
  // 其他方法...
}

这样当el-cascader获得焦点时，addressFocus方法会被触发，你可以在其中添加相应的逻辑处理。<span class="em">1</span><span class="em">2</span>
