最近根据需求完成表单提交按钮（方便自己以后使用）

只有代码

首先表单prop，ref 都要保持一致

<el-form :model="form" ref="formData" :rules="rules">
        <el-form-item label="实际停电时长" :label-width="formLabelWidth" prop="powerCutTimeActual">
                <el-input v-model="form.powerCutTimeActual" autocomplete="off" required="required"></el-input>
        </el-form-item>
</el-form>
<div slot="footer" class="dialog-footer">
      el-button @click="dialogFormVisible = false">取 消</el-button>
      <el-button type="primary" @click="submitIsPower('formData')" :validate-event="false">确 定</el-button>
</div>```

```javascript
form: {
         powerCutTimeActual: ''
            },
rules: {
          powerCutTimeActual: [
             { required: true, message: '实际停电时长不能为空'},
                ]
       },

第三步

submitIsPower(formData) {
            this.$refs[formData].validate((valid) => {
                if (valid) {
                   
                }
            })
        },
