javascript - 从 URL 末尾删除尾随 '/'

Question

所以我有以下一些在某种程度上有效的代码。

var url = window.location.protocol + "//" + window.location.host + window.location.pathname;

var sanitized = url
    .replace(/^https\:\/\//, '') // remove the leading http:// (temporarily)
    .replace(/\/+/g, '/')       // replace consecutive slashes with a single slash
    .replace(/\/+$/, '');       // remove trailing slashes

url = 'https://' + sanitized;

window.onload = function urlChange(){
    location.replace(url);
}

唯一的问题是，一旦 url 发生更改，页面就会不断重新加载，就像无限循环一样。

有什么想法吗？

谢谢!

您需要检查网址是否实际更改，并且仅在更改后才替换其位置。您可能还应该使用 window.url，而不是根据协议(protocol)、主机和路径名手动构建它。

var sanitized = window.url
                      .replace(/^https\:\/\//, '') // remove the leading http:// (temporarily)
                      .replace(/\/+/g, '/') // replace consecutive slashes with a single slash
                      .replace(/\/+$/, ''); // remove trailing slashes

sanitized = 'https://' + sanitized; // add https to the front

window.onload = function urlChange() {
    if (window.url !== sanitized) {
        location.replace(sanitized);
    }
}
