在javascript中打开本地文件系统中的文件 [英] Opening a file in local file system in javascript

问题描述

我正在寻找一种打开.xls文件的方法，该文件位于临时目录中，在IE和Firefox浏览器中使用javascript。我尝试使用javascript如下，

I am looking out for a way to open a .xls file which is in temp directory using javascript in IE and Firefox browser. I tried using the javascript as follows,

function openMe(){
    var newwindow=window.open("file:///{path to temp dir}/names.xls","window2","");
}

names.xls文件存在于那里，我已经验证了。由于安全问题，因为IE 7.0不允许用户打开一个空白窗口，所以我无法使此工作。我还没有检查过Firefox。有没有办法让这个工作？

The names.xls file exists there, I have verified it. As IE 7.0 does not let a user open a blank window due to security issues I am unable to make this work. I have not checked it with firefox yet. Is there any way to get this working?

我也尝试过一个empty.html其中有这个javascript并在这个称为openMe（）的body上。并从父HTML文件打开empty.html。所有我看到的是一个新的空白窗口，没有任何东西，但文件没有打开。

I also tried having an empty.html which has this javascript and calling this openMe() body onLoad. And opening the empty.html from the parent HTML file. All I see is a new blank window without nothing but the file does not open.

任何指针都将非常有用。谢谢

Any pointers would be greatly helpful.Thanks

干杯，
Abi

Cheers, Abi

推荐答案

对不起，阿比，你没有运气 - 你无法在浏览器中使用JavaScript在本地文件系统上打开文件。这是一个安全问题，如果你考虑这个问题，就会是完美的;您不希望人们在他们的网站上编写脚本，可以访问本地文件系统上的文件，并可能从他们那里读取数据！

Sorry, Abi, you're out of luck--you can't use JavaScript in a browser to open a file on the local file system. This is a security issue and makes perfect sense if you think about it; you wouldn't want people writing scripts on their web sites that can access files on your local file system and possibly read data from them!
