Hi! How do we trim out or remove a part of a URL or path?

eg. http://www.mywebsite/folder/somefile.htm ----I want to trim
http://www.mywebsite/folder/ so All I have left is the file name.

<script language="JavaScript">

var pathtotrim = location.href;
document.write (pathtotrim);

</script>

推荐答案

不推荐使用，请改用以下内容：


< script type =" text / javascript">

var pathtotrim = location.href;
document.write（pathtotrim）;

<script language="JavaScript">

Deprecated, use the following instead:

<script type="text/javascript">
var pathtotrim = location.href;
document.write (pathtotrim);

这样的事情应该这样做：


var path = location。 pathname.split（''/''）;

path.pop（）;

alert（location.protocol +''//''+ location.host + path.join（''/''）+''/''）;

Something like this should do it:

var path = location.pathname.split(''/'');
path.pop();
alert(location.protocol + ''//'' + location.host + path.join(''/'') + ''/'');

< script type =" text / javascript">

var pathfortrim = self.location.pathname;

alert（pathfortrim.substring（pathfortrim.lastIndexO f（''/''）+ 1））;

< / script>

请注意，由于跨平台的不同* local * path语法

和浏览器，此解决方案可能会因Mac而失败肯定是

IE / Win本地文​​件。

然而它总是适用于URL'。


For一个真的通用解决方案然后应该使用RegExp，这是我b $ b不强的。

<script type="text/javascript">
var pathfortrim = self.location.pathname;
alert(pathfortrim.substring(pathfortrim.lastIndexO f(''/'')+1));
</script>

Please note that due to different *local* path syntax across platforms
and browsers this solution will possibly fail for Mac and for sure for
IE/Win for local files.
Nevertheless it will always work for URL''s.

For a really universal solution a RegExp should be used then, which I''m
not strong at.

HI！非常感谢所有的信息，我试着看看哪一个在我的

情况下效果最好。 :)
