Get only file name from file input on internet explorer
提问by user937450
I need to return only the file name from an HTML input file.
我只需要从 HTML 输入文件中返回文件名。
<input type="file" id="whatever" />
The JavaScript code im using to get the name of the file is:
我用来获取文件名的 JavaScript 代码是：
document.getElementById("whatever").value;
In firefox it gives only the file name which is what I want, but in IE I get the full path.
在 Firefox 中，它只给出了我想要的文件名，但在 IE 中我得到了完整路径。
I think that string manipulation is the only way to get the name.
我认为字符串操作是获取名称的唯一方法。
What would be the easiest/shortest way to get only the name (extension too) in JavaScript? Thanks.
在 JavaScript 中仅获取名称（扩展名）的最简单/最短方法是什么？谢谢。

You can try this
你可以试试这个
var path = document.getElementById("whatever").value;
var fileName = path.match(/[^\/\]+$/);
console.log(fileName);

var path = document.getElementById("whatever").value;
var filename = path.substring(path.lastIndexOf("/") + 1);
This will give you everything after the last /, but is also compatible with a lack of /s. In case you also need to deal with \as the lovely path separator, you can always use this first:
这将为您提供 last 之后的所有内容/，但也与缺少/s兼容。如果您还需要处理\可爱的路径分隔符，您可以先使用它：
path.replace(/\/g, "/")
