项目中遇到的ts问题汇总

 

报错关键词句	报错截图	解决
Declaration of public static field not allowed after declaration of public instance method. Instead, this should come at the beginning of the class/interface. (member-ordering)tslint(1)		把defaultProps和state移动至最前面即可:
Identifier 'tempOpt' is never reassigned; use 'const' instead of 'let'. (prefer-const)tslint(1)		把let换成const即可
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： https://www.tslang.cn/docs/handbook/basic-types.html
Class name must be in pascal case (class-name)tslint(1)		接口名应采用大驼峰的写法：CityItem
Forbidden bitwise operation (no-bitwise)tslint(1)		禁止使用位运算符哎╮(╯▽╰)╭
if statements must be braced (curly)tslint(1)		if 语句要写完整
Multiline JSX elements must be wrapped in parentheses (jsx-wrap-multiline)tslint(1)		return 后面必须用中括号括起来： 而且括号需转行：
JSX elements with no children must be self-closing (jsx-self-close)tslint(1)		没有children元素必须自合,eg:
Unnecessarily quoted property 'xxxxx' found. (object-literal-key-quotes)tslint(1)		key没必要加引号
Uncaught ReferenceError: React is not defined	由于第二行只引入了Input 但是 居然还没用过，所以报错：	把引入Input的哪一行删掉或者把Input用起来即可
Multiline JSX elements must be wrapped in parentheses (jsx-wrap-multiline)tslint(1)		多行JSX元素必须用括号括起来
Use a template literal instead of concatenating with a string literal. (prefer-template)tslint(1)		？？？
元素隐式具有 "any" 类型，因为类型“{}”没有索引签名		类似解决方案：
