获得这个的简单方法是：

An easy way to get this is:

function getPathFromUrl(url) {
  return url.split("?")[0];
}

对于那些也希望删除哈希的人（不是原始问题的一部分）当没有查询字符串存在时，需要更多一点：

For those who also wish to remove the hash (not part of the original question) when no querystring exists, that requires a little bit more:

function stripQueryStringAndHashFromPath(url) {
  return url.split("?")[0].split("#")[0];
}

@caub（最初是@crl）提出了一个更简单的组合，适用于查询字符串和哈希（虽然它使用RegExp，以防任何人遇到问题）：

@caub (originally @crl) suggested a simpler combo that works for both query string and hash (though it uses RegExp, in case anyone has a problem with that):

function getPathFromUrl(url) {
  return url.split(/[?#]/)[0];
}
