reader.onload = function(event) { const fileContent = event.target.result; // 在这里可以对文件内容进行处理 }; 接下来,使用reader对象的readAsText方法读取文件。readAsText方法接受一个File对象作为参数,该对象可以通过input元素的files属性获取: 代码语言:txt 复制 const fileInput = document.get...
“smarter” about these sorts of patterns. In TypeScript 3.1, for any function declaration orconstdeclaration that’s initialized with a function, the type-checker will analyze the containing scope to track any added properties. That means that both of the examples – both ourreadFileas well ...
import{readFile}from'fs';readFile('hoge','utf-8',(err,content)=>{if(!err)console.log(content);}); To allow Tsuquyomi to import the shortest path instead of the complete one (where the initial module declaration is) one, put this in your .vimrc: ...

” You many never have to use the declare keyword yourself because you can find definition files for most JavaScript libraries on the DefinitelyTyped site atdefinitelytyped.org. Through these definition files, TypeScript can effectively “read the documentation” about the libraries with which you ...
