el-option

1. Code

<el-form-item label="分屏数">
  <el-select v-model="form.screens" 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>

2. Pay attention

1. The value displayed by the v-module attribute in el-select is the value selected by el-option by default. 2. The
label attribute in el-option is the value displayed in the drop-down list on the front-end page, and the value attribute is The value 3 we pass into the backend
is included in the fact that we want to fetch data from the database and assign the value to form.screens so that multiple el-options can be selected by default. The value in form.screens here is the value of value. Only then can el-option be selected by default, but not label.
4. When we select an el-option and print the value of form.screens, the result is the value of value, not the value of label.
