如何在Javascript中从右侧第一个斜杠之前获取字符串中的文本？[关闭]

  • 772

再会！

我的 js 文件中有以下几行。我只需要从这些行中获取图片的名称和扩展名。也就是说，我需要第一个斜线之前右边的文本。我怎么才能得到它？

以下是这些行：

assets/img/header/item.png
assets/img/header/item2.png
assets/img/why/lightning_bg_4x.png
assets/img/why/target_1.png
assets/img/case/case-2.png
assets/img/case/case-1.png

感谢您的关注

  1. const href = [
  'assets/img/header/item.png',
  'assets/img/header/item2.png',
  '/img///////header/item3.png',
  'item8.png',
]

for (let h of href){
  console.log(h.replace(/(.*\/)+/g, ''))
}

    let arr = [
    'assets/img/header/item.png',
    'assets/img/header/item2.png',
    'assets/img/why/lightning_bg_4x.png',
    'assets/img/why/target_1.png',
    'assets/img/case/case-2.png',
    'assets/img/case/case-1.png'
];


arr.forEach(item => {
    console.log(item.split('/').pop());
});
