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);

这个怎么样:location。href。切片(0，- (location。Search + location.hash).length))

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

Try:

document.location.protocol + '//' +
document.location.host +
document.location.pathname;

(注意:.host而不是.hostname，这样端口也包括在内，如果需要的话)

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>
