Is there a way that I can get the last value (based on the '\' symbol) from a full path?

Example:

C:\Documents and Settings\img\recycled log.jpg

With this case, I just want to get from the full path in JavaScript.recycled log.jpg

答案 1

var filename = fullPath.replace(/^.*[\\\/]/, '')

This will handle both \ OR / in paths

答案 2

Just for the sake of performance, I tested all the answers given here:

var substringTest = function (str) {
    return str.substring(str.lastIndexOf('/')+1);
}

var replaceTest = function (str) {
    return str.replace(/^.*(\\|\/|\:)/, '');
}

var execTest = function (str) {
    return /([^\\]+)$/.exec(str)[1];
}

var splitTest = function (str) {
    return str.split('\\').pop().split('/').pop();
}

substringTest took   0.09508600000000023ms
replaceTest   took   0.049203000000000004ms
execTest      took   0.04859899999999939ms
splitTest     took   0.02505500000000005ms

And the winner is the Split and Pop style answer, Thanks to bobince !
