问题描述

我想用 javascript 读取本地文件.我有以下功能

I want to read a local file with javascript. I have the following function

$(function() {
        console.log("antes de readTextFile");
        readTextFile("file:///D:/carlota/eusruveyadmin/manuales/ficheropprueba.txt")

    });

    function readTextFile(file)
    {
        console.log("readFile principio");
        var rawFile = new XMLHttpRequest();
        rawFile.open("GET", file, false);
        rawFile.onreadystatechange = function ()
        {
            if(rawFile.readyState === 4)
            {
                if(rawFile.status === 200 || rawFile.status == 0)
                {
                    var allText = rawFile.responseText;
                    console.log("readFile fichero ",allText);
                }
            }
        }
        rawFile.send(null);
    }

在控制台浏览器中，我收到以下消息拒绝访问"

In the console browser I have the following message "denied access"

我在浏览器中查看了我的文件，我可以看到该文件

I checked in the browser my file and I can see the file

文件路径怎么写?

推荐答案

如果您使用的是 IE，则需要设置 Settings/Tools->Internet Options->Security->Custom Level 并更改Miscellaneous"设置下的安全设置启用跨域访问数据源".

If you're using IE you need to set Settings/Tools->Internet Options->Security->Custom Level and change security settings under "Miscellaneous" set "Access data sources across domains" to Enable.

但如果您的应用用户使用的是 IE 并且没有相同的设置，则它不会对您的应用程序用户起作用

But it won't work for the users of your app, if they're using IE and don't have the same setting
