如何从特定字符中删除部分字符串？

Question

我有以下 url：

http://intranet-something/IT/Pages/help.aspx?kb=1

我想删除?kb=1并将http://intranet-something/IT/Pages/help.aspx分配给一个新变量。

到目前为止，我已经尝试了以下方法：

var link = "http://intranet-something/IT/Pages/help.aspx?kb=1"

if(link.includes('?kb=')){
  var splitLink = link.split('?');
}

然而，这只是删除了问号。

url末尾的1可以改变。

如何从问号中删除所有内容，包括问号？

使用URL接口来操作 URL：

 const link = "http://intranet-something/IT/Pages/help.aspx?kb=1"; const url = new URL(link); url.search = ''; console.log(url.toString());

 var link = "http://intranet-something/IT/Pages/help.aspx?kb=1" if (link.includes('?kb=')) { var splitLink = link.split('?'); } var url = splitLink? splitLink[0]: link; console.log(url);

 var link = "http://intranet-something/IT/Pages/help.aspx?kb=1" if(link.includes('?kb=')){ var splitLink = link.split('?'); console.log(splitLink[0]); }

你也可以这样尝试
