是否有可能在未提供服务的页面上使用JS / HTML5 FileReader加载文件？ [英] Is it possible to load a file with JS/HTML5 FileReader on non served page?

问题描述

我想在HTML5 / JS中创建一个简单的游戏，我不希望用户运行任何网络服务器或必须连接到网站。 （只是一个HTML页面）

但它看起来像FileReader只能用于文件类型输入。

是否有可能只有两个文件：index.html和foo.txt并排，并从index.html读取foo.txt，如下所示：

  //没有输入需要，我知道我想读取
 var my_file = new File（foo.txt）; 
 var reader = new FileReader（）; 
 alert（reader.readAstext（my_file，UTF-8））; 
  

任何想法？

解决方案

我相信这是你的答案：如何使用Javascript打开本地磁盘文件？

总之，您看起来像这样：

 < input type =fileid =filesname =file/> 
  

HTML5允许您加载本地存储在计算机上的文件，但无法选择它。用户必须选择他/她想要加载的文件。

想象一下，当开发者（或者说更好的口语，黑客）会可以访问每个人的本地数据......

I want to create a simple game in HTML5/JS and I don't want the user to run any webserver or to have to connect to a website. (just an HTML page)

But it looks like FileReader can only be used on files type inputs.

Is it possible to have only two files : index.html and foo.txt side by side and to read foo.txt from index.html with something like :

// No input needed, I know waht I want to read
var my_file = new File("foo.txt");
var reader = new FileReader();
alert( reader.readAstext( my_file, "UTF-8" ) );

Any idea ?

解决方案

I believe that this is your answer: How to open a local disk file with Javascript?

In short, you are looking something like this:

<input type="file" id="files" name="file" />

HTML5 allows you to load files which are stored locally on computer, but you cannot select it. User must select file which he/she wants to be loaded.

Just imagine what would happen when developers (or better spoken, hackers) would have access to everyones local data...
