elementui如何获取选择器的值

像这样的options：["12.30","12.40"]怎么赋值呢？
<el-option
                    v-for="item in options"
                    :key="item"
                    :value="item">
   </el-option>

<el-select v-model="optionsValue">
      <el-option
        v-for="item in options"
        :key="item"
        :value="item">
      </el-option>
    </el-select>

data () {
      return {
        optionsValue: '',
        options: ['12.30', '12.40']
      }
    },

v-mode就可以啊
