jQuery：从文件系统读取文本文件 [英] jQuery: read text file from file system

问题描述

  // LOAD文件并逐行拆分并附加div 
 $ .get（'myFile.txt'，function（data）{
 var lines = data.split（\\\
）; 
 
 $。 each（lines，function（n，elem）{
 $（'＃myContainer'）。append（'< div>'+ elem +'< / div>'）; 
}）; 
}）; 
  

在chrome中，我得到：

  XMLHttpRequest无法加载文件：/// C：/myPath/myFile.txt。 Access-Control-Allow-Origin不允许Origin null。 
  

Firefox显示没有错误，但代码未执行（我在firebug中有断点，匿名功能从不

任何帮助赞赏！

编辑：

不得不：

• 使用文件完整路径


• 启动
  chrome with
  --allow-file-access-from-files

now它的工作正常！

解决方案

您不能从本地文件系统加载文件，像这样，你需要把它放在一个web服务器，并从那里加载它。在与您的JavaScript相同的网站上。

编辑：看这个线程，您可以使用选项启动chrome - allow-file-access-from-files ，这将允许访问本地文件。

I am trying to read a text file using jquery, like this:

// LOAD file and split line by line and append divs
$.get('myFile.txt', function(data) {    
    var lines = data.split("\n");

    $.each(lines, function(n, elem) {
       $('#myContainer').append('<div>' + elem + '</div>');
    });
});

In chrome, I am getting:

XMLHttpRequest cannot load file:///C:/myPath/myFile.txt. Origin null is not allowed by Access-Control-Allow-Origin.

Firefox shows no error but the code is not executed (I have breakpoints in firebug and the anonymous function never runs).

Any help appreciated!

EDIT:

had to:

• use the file full path
• launch chrome with "--allow-file-access-from-files"

now it's working OK!

解决方案

You can't load a file from your local filesystem, like this, you need to put it on a a web server and load it from there. On the same site as you have the JavaScript loaded from.

EDIT: Looking at this thread, you can start chrome using option --allow-file-access-from-files, which would allow access to local files.
