在vue項目中在elementUI中使用敲擊回車登錄效果

<el-form-item>
   <el-button type="primary" @click="submitForm('ruleForm')">登錄</el-button>
   <el-button @click="$router.push('/register')">註冊</el-button>
</el-form-item>

在vue的created鉤子函數中寫

 // 鉤子函數
  created() {
    // let that = this;
    document.onkeypress = (e)=>{
      var keycode = document.all ? event.keyCode : e.which;
      if (keycode == 13) {
        this.submitForm('ruleForm');// 登錄方法名
         return false;
      }
    };
  },
methods:{
   submitForm(formName) {} //登錄方法

}
