elemetUI开关状态误操作

 好了，可以倒计时了。。。我想回家

<el-form-item>
     <el-switch  v-model="ruleForm.useStatus" @change="switchVhange()"></el-switch>
      <em v-if="ruleForm.useStatus == true">开启</em>
      <em v-else>关闭</em>
</el-form-item>

ruleForm:{useStatus: true}

switchVhange() {
     if(!this.ruleForm.useStatus == true) {
         this.$alertMsgBox(
              "是否确定关闭状态",
              "系统提示",
              "此为门店内部信息，请谨慎填写",
              "el-icon-question",
               "#FE9100")
          .then(() => {
                this.$messageOK("success", "已关闭");
})
           .catch(() => {
                this.ruleForm.useStatus = true
                this.$messageOK("info", "已取消");
});
         } else if(!this.ruleForm.useStatus == false) {
                this.$alertMsgBox(
                  "是否确定开启状态",
                   "系统提示",
                   "此为门店内部信息，请谨慎填写",
                   "el-icon-question",
                   "#FE9100")
                    .then(() => {
                       this.$messageOK("success", "已开启");
})
                    .catch(() => {
                        this.ruleForm.useStatus = false
                         this.$messageOK("info", "已取消");
 });
                }
            }
