错误ts2683 可以通过在函数参数中显式声明 this 的类型来解决。 在TypeScript 中,当你遇到错误 ts2683: 'this' implicitly has type 'any' because it does not have a type annotation 时,这通常意味着 TypeScript 无法确定 this 关键字的类型。这通常发生在类外部的函数中,或者是在嵌套函数中,当 TypeScript...
const foo = new Foo(); foo.on(‘error’, function(err: any) { console.log(err); this.emit(‘end’); // error:thisimplicitly has typeany}); 将类型化的 `this` 添加到回调参数会导致相同的错误: foo.on(‘error’, (this: Foo, err: any) => { // error:thisimplicitly has typeany ...
};conste1 =newEmployee('Tom',100);console.log(e1.getSalary()); 当TypeScript 无法确定 this 关键字的类型时,会出现“this implicitly has type any”错误,因为我们已经在类之外或嵌套函数中使用了它。 在类之外使用时,默认情况下它的类型为 any。 以下是会产生错误的代码示例: classEmployee{first: string...
"this" 隐式具有类型 "any",因为它没有类型注释 'this' implicitly has type 'any' because it does not have a type annotation 解决方案: 将this放在函数参数列表上声明类型即可,使用的时候this不会干扰形参传入顺序 constfn= () => {returnfunction(this:any, ...args:any[]) {letthat =thisconsole.l...

在TypeScript中,this 关键字的类型推断可能会导致一些问题,特别是在没有明确类型注释的情况下。当TypeScript编译器无法确定this的具体类型时,它会默认将其推断为any类型,这会失去类型检查的好处。 基础概念 this 关键字在JavaScript和TypeScript中用于引用当前执行上下文的对象。它的值取决于函数的调用...
