Yup, here's an example.
[small](note the onload function that alerts the page has been loaded - it does not retrigger after clicking the button which proves the page is not reloaded - I put it in cause I wasn't sure myself

Cheers Kaht. That very nearly worked. The only problem I have is that if the link is re-clicked I end up with multiple anchors in the URL is
is there a way to check if an anchor exists before adding it on the end?
is there a way to check if an anchor exists before adding it on the end?
just use a sexy regexp to strip off the existing anchor declaration:
-kaht
[small](All puppies have now found loving homes, thanks for all who showed interest)[/small]
Code:
function jumpToAnchor() {
window.location = window.location.[!]replace(/\#.*$/, "")[/!] + "#blah";
}-kaht
[small](All puppies have now found loving homes, thanks for all who showed interest)[/small]
hmmm..... you'll probably wanna cast that as a string before running the replace method:
-kaht
[small](All puppies have now found loving homes, thanks for all who showed interest)[/small]
Code:
function jumpToAnchor() {
window.location = [!]String([/!]window.location[!])[/!].replace(/\#.*$/, "") + "#blah";
}-kaht
