如何在JavaScript中提取字符串最后一个斜杠后的子串

核心逻辑都是定位字符串中最后一个/的索引后截取后续内容，也可以直接调用语言内置的路径处理工具，规避特殊字符、不同系统路径分隔符的兼容问题：

Python 实现 #

方法1：字符串内置方法直接截取 #

path = "file:///storage/emulated/0/Android/data/com.myapp/files/Pictures/00cb3b0b-45d5-486b-8f33-0fa3bf2285ff.jpg"
file_name = path[path.rfind("/") + 1:]

方法2：用路径处理模块更稳妥 #

import os
path = "file:///storage/emulated/0/Android/data/com.myapp/files/Pictures/00cb3b0b-45d5-486b-8f33-0fa3bf2285ff.jpg"
file_name = os.path.basename(path)

JavaScript 实现 #

const path = "file:///storage/emulated/0/Android/data/com.myapp/files/Pictures/00cb3b0b-45d5-486b-8f33-0fa3bf2285ff.jpg"
const fileName = path.split('/').pop()

Java 实现 #

String path = "file:///storage/emulated/0/Android/data/com.myapp/files/Pictures/00cb3b0b-45d5-486b-8f33-0fa3bf2285ff.jpg";
String fileName = path.substring(path.lastIndexOf("/") + 1);

Shell/Bash 实现 #

path="file:///storage/emulated/0/Android/data/com.myapp/files/Pictures/00cb3b0b-45d5-486b-8f33-0fa3bf2285ff.jpg"
file_name=${path##*/}
