有没有办法在 JavaScript 中从这个 URL 中删除 # 之后的任何内容

【问题讨论】：

标签： javascript

【解决方案1】：

你可以用#分割它，然后取第一个元素

const url = 'https://www.tripadvisor.co.uk/ShowUserReviews-g503793-d571919-r748731637-Premier_Inn_Waltham_Abbey_hotel-Waltham_Abbey_Essex_England.html#review748731637'

console.log(url.split('#')[0])

或者使用正则表达式匹配特定组

const url = 'https://www.tripadvisor.co.uk/ShowUserReviews-g503793-d571919-r748731637-Premier_Inn_Waltham_Abbey_hotel-Waltham_Abbey_Essex_England.html#review748731637'

const [_, res] = /(.*)#.*/.exec(url)

console.log(res)

const url = "https://www.tripadvisor.co.uk/ShowUserReviews-g503793-d571919-r748731637-Premier_Inn_Waltham_Abbey_hotel-Waltham_Abbey_Essex_England.html#review748731637"

firstPartUrl = url.split('#')[0]
