试试下面的方法:

window.history.back(1);

const url = new URL(window.location);
url.hash = '';
history.replaceState(null, document.title, url);

你可以这样做:

history.replaceState({}, document.title, window.location.href.split('#')[0]);

<script type="text/javascript">
var uri = window.location.toString();
if (uri.indexOf("?") > 0) {
    var clean_uri = uri.substring(0, uri.indexOf("?"));
    window.history.replaceState({}, document.title, clean_uri);
}
</script>

把这个代码放在头部分

简单优雅:

history.replaceState({}, document.title, ".");  // replace / with . to keep url

要删除散列，可以尝试使用此函数

function remove_hash_from_url()
{
    var uri = window.location.toString();
    if (uri.indexOf("#") > 0) {
        var clean_uri = uri.substring(0, uri.indexOf("#"));
        window.history.replaceState({}, document.title, clean_uri);
    }
}
