element-plus动态判断表单是否是必填项。出错时显示的错误。在不是必填项时为什么还能显示

选择否后面输入框不可编辑

选择是，后面输入框为必填

现在的问题时，默认是不可编辑的。但是我选择是之后自动校验提示了。

再等我再切回否时。之前的红色提示文字还在。但实际上点表单的提交是可以正常提交的。

解决办法：在最后提交时根据前面的是否再给表单做校验。

<el-form ref="ruleFormRef" :model="formData" label-width="140px" label-position="right" label-suffix=" :" :rules="rules">

<el-form-item label="是否民政补贴" >
      <el-radio-group v-model="formData.subsidySign" class="radioStyle">
        <el-radio :value="1">是</el-radio>
        <el-radio :value="0">否</el-radio>
      </el-radio-group>
  </el-form-item> 
 <el-form-item prop="subsidyAmount">
      <el-input
        v-model="formData.subsidyAmount"
        :disabled="formData.subsidySign != 1"
        @blur="calcAmount"
        placeholder="请输入补贴金额"
        clearable>
        <template #append>元</template>
      </el-input>
</el-form-item>

<el-button type="primary" @click="handleSubmit" >确定</el-button>

</el-form>

const formData = reactive({
  subsidySign:0, //是否民政部贴
  subsidyAmount: "", //补贴金额
});

const rules = reactive({
  subsidyAmount: [{ required: false, message: "请输入补贴金额" }],

});

const handleSubmit = () => {
  if(formData.subsidySign==1){//是民政补贴，补贴金额必须填
    rules.value.subsidyAmount[0].required=true;
  }else{
    rules.value.subsidyAmount[0].required=false;
  }

}
