location.toString().replace(location.search, "")

这里有两种方法:

<script type="text/javascript">
    var s="http://localhost/dms/mduserSecurity/UIL/index.php?menu=true&submenu
                                =true&pcode=1235";

    var st=s.substring(0, s.indexOf("?"));

    alert(st);

    alert(s.replace(/\?.*/,''));
</script>

试试这个:

让path = window.location. hrf .split('?')[0] console.log ({path})

var url = window.location.origin + window.location.pathname;

location.toString().replace(location.search, "")

你可以创建一个URL实例，然后清除查询字符串:

const url = new URL(document.location.href);
url.search = '';
console.log(url.href);
