1. 解释SyntaxError: await is only valid in async functions and the top level错误的含义 这个错误表明你试图在非异步函数(即没有用async关键字声明的函数)中使用await关键字,或者在不支持await使用的顶层作用域(即不在异步函数或模块顶层)中使用await。在JavaScript中,await关键字用于等待一个Promise解决(resolve)...
{constdata =awaitCSVtoJSON().fromFile('./input.csv')returndata }lettemp =awaittest()console.log(temp) 无论我尝试过哪种方式,我总是会收到以下错误 let temp = await test() ^^^ SyntaxError: await is only validinasync functionsandthe top level bodies of modules at Object.compileFunction (no...
Thesyntaxerror await is only valid in async function,indicating that you are trying to use theawaitkeyword outside of anasyncfunction. For example: const result = await someAsyncTask(); console.log(result); Output: SyntaxError: await is only valid in async functions and the top level bodies ...
currently, we have 2 retools, 1 is self-hosted and the 2nd one, we use retool's hosting. we created the same tools on both retools but on the self-hosted retool we are getting this error: > await is only valid in async functions and the top-level bodies of modules but on ...
确保await关键字只在async函数内部使用,并且被await的表达式必须是一个返回 Promise 的异步函数。 示例代码 错误的用法: 代码语言:txt 复制 function fetchData() { let result = await fetch('https://api.example.com/data'); // SyntaxError: await is only valid in async functions and th...
async await我们直接进入主题!!!1.async和await是什么? async: 是ES7语法,用于声明一个function是异步函数。 await: 等待一个异步方法完成。 ps:await只能出现在async函数中,不然会报错,如示例1-1; Uncaught SyntaxError: await is only valid in async functions and the top level bodies of modules Await只在...
(async () => {try {await fetch1(url);await fetch2(url);} catch (err) {// TODO}})(); 1. 2. 3. 4. 5. 6. 7. 8. 也要注意 await 必须写在 async 函数里,否则会报错 SyntaxError: await is only valid in async functions and the top level bodies of modules。
1.Await只能在Async函数中使用 在Async函数之外使用Await会导致语法错误,因此需要确保Await的代码块位于Async函数内部。 代码语言:javascript 复制 // 错误示例:letresult=awaitfetch("https://jsonplaceholder.typicode.com/todos/1");// SyntaxError: await is only valid in async functions and the top level bodie...
const a= await 'Hello World';//上述写法会报错的:await is only valid in async functions and the top level bodies of modules//相当于const a = await Promise.resolve('Hello World');//所以直接写同步代码即可,不需要 await 关键字const a = 'Hello World'; 异步代码 //2s 之后...
(async()=>{try{awaitfetch1(url);awaitfetch2(url);}catch(err){// TODO}})(); 也要注意 await 必须写在 async 函数里,否则会报错SyntaxError: await is only valid in async functions and the top level bodies of modules。 代码语言:javascript ...
