| Shadowed name: 'id' (no-shadowed-variable)tslint(1) | 似乎不能用id命名，改其他命名即可
|
|
| Type 'string' is not assignable to type '"" | "success" | "error" | "warning" | "validating"'.ts(2322) | vldStatus 已经是'success'了，但是还是报错： |
定义一个类型，利用"类型断言"解决： |

|
| Unnecessarily quoted property 'xxxxx' found. (object-literal-key-quotes)tslint(1) | key没必要加引号 | |

把引入Input的哪一行删掉或者把Input用起来即可 |
