Getting just the filename from a path with JavaScript
提问by DCD
I have a full path to an image, which I am using jQuery to read like this:
我有一个图像的完整路径，我使用 jQuery 来读取它：
$('img.my_image').attr('src');
However I just want the filenameportion (i.e. without full path).
但是我只想要文件名部分（即没有完整路径）。
Are there any built-in functions to do this, or would a regexbe the only option?
是否有任何内置函数可以做到这一点，或者正则表达式是唯一的选择？

var Filename= path.split('/').pop()

var fileNameIndex = yourstring.lastIndexOf("/") + 1;
var filename = yourstring.substr(fileNameIndex);

function getFileName(path) {
return path.match(/[-_\w]+[.][\w]+$/i)[0];
}

I found a better version handling unix and windows-like path-strings.
我找到了一个更好的版本来处理 unix 和类似 windows 的路径字符串。
Number 1:
1号：
var unix_path = '/tmp/images/cat.jpg';
console.log(unix_path.replace(/^.*[\\/]/, ''));
var win_path = 'c:\temp\images\cat.jpg';
console.log(win_path.replace(/^.*[\\/]/, ''));
Output will be cat.jpg
输出将是cat.jpg
Number 2: (maybe faster)
2号：（也许更快）
var unix_path = '/tmp/images/cat.jpg';
console.log(unix_path.split(/[\\/]/).pop());
var win_path = 'c:\temp\images\cat.jpg';
console.log(win_path.split(/[\\/]/).pop());
Output will be cat.jpg
输出将是cat.jpg

In Javascript you could do
在 Javascript 你可以做
function getFileNameFromPath(path) {
var ary = path.split("/");
return ary[ary.length - 1];
}

Using this solution you can get both names i.e. with and without file extension.
使用此解决方案，您可以获得两个名称，即带有和不带有文件扩展名。
//getting image source
var path=$('img.my_image').attr('src');
//splitting url and getting filename with file extension
var file=path.split('/').pop();
//removing extension and keeping just the filename
var filename=file.split('.').shift();
