我想用myFunction()获取文件
如果用户将相对路径作为函数参数传递,如何获取该文件
../somewhere/index.js
import {myFunction} from "../pathTo/app.js";
myFunction("../relative/path/file.txt");
app.js
export const myFunction = (path) => {
fs.readFile(path); //=> How to get the file here
};
假设有一个文件路径var dir = "my/file/directory",我提供了一个相对文件路径var rel = "../../other/directory/myFile.js",如何计算实际目录:
var dir = "my/file/directory"
var rel = "../../other/directory/myFile.js"
var nDir = func(dir,rel) // returns "my/other/directory/myFile.js"
到目前为止,我已经找到了pa
当我做git status时,会出现这样的情况:
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: src/app.js
modified: src/view/view.js
modified: sr
因此,为了方便和可读性,总是一个好主意,声明您的变量在顶部,即;
然而,我想知道js如何处理所需的文件。它是在声明时加载还是在执行时加载?上面的声明是否有意义(如果运行程序只需要一个“文件”)?
var File1 = require('../api/file1.js');
var File2 = require('../api/file2.js');
var File3 = require('../api/file3.js');
var File4 = require('../api/file3.js');

I have one .js file named final.js which I copied as bundle resource I have a requirement like the html document which reads this js file should download at runtime and store it in documents directory.

我正在尝试使用webpack 4创建JavaScript库和CSS包(提取单个文件中使用的所有CSS )。
我的webpack.config.js文件配置如下:
var path = require("path");
var HtmlWebpackPlugin = require("html-webpack-plugin"); // Require to generate html file
var MiniCssExtractPlugin = require("mini-css-extract-plugin"); // Require to
我试图搜索我的代码库中的所有jscript目录,然后使用以下批处理脚本获取这些目录中的相关文件列表.
@echo off
setlocal enableextensions enabledelayedexpansion
FOR /F "tokens=*" %%G IN ('DIR /B /AD /S jscripts') DO (
CD %%G
CD dev
SET "currentDir=!cd!"
IF NOT "!currentDir:~-1!"=="\" SET
我以前没有使用过sourcemaps和typescript,所以请记住这一点。
我必须与多个typescript文件编译成单个javascript文件的项目一起工作。
我有以下文件:
lib.js (the compiled js code of the project)
lib.js.map (the source map of the lib.js)
lib.d.ts (the "header" of the lib.js before it was compiled)
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0

当我使用grunt启动一个收听localhost:9000的服务器时,页面看起来和工作都很好。当我试图在浏览器中加载index.html时,我无法访问bower_components文件夹,该文件夹是目录中index.html之上的一个文件夹。
GET file:///bower_components/modernizr/modernizr.js net::ERR_FILE_NOT_FOUND
index.html:190 GET file:///bower_components/jquery/dist/jquery.js net::ERR_FILE_NOT_FOUND
我的index.html文件如下所示
<html>
<body>
<script src="public/jquery-latest-min.js"></script>
/*But this script file is not importing and creating error */
</body>
</html>
app.js代码是
var express = require('express'),
app =
假设有两个文件 ./file2.js
function scriptpath()
return __filename
./file1.js
var path = file2.scriptpath()
console.log(path) //returns absolute path of file2.js but not file1.js 我希望从调用文件的位置获得文件(file1.js)的绝对路径。
