Strip off everything after #anchor including the #anchor

Change this...

www.sample.com/sample.html#commentxxx?stuffhereIdontneed

into this...

www.sample.com/sample.html

I have it in a link so I think I need a regex?

doc开发者_C百科ument.write("<a href='"+ window.location.href.replace('?????', '') +  
"?ThisIsAppendedLater'>sample</a>");

Nathan's answer is good. For completeness' sake; here's the regex:

var stripped = window.location.href.replace(/#.*$/,'');

---

window.location.hash = '';

---

url.substring(0,url.indexOf("#"))

If you want a regex based solution, you can use:

window.location.href.replace('#.*', '');
