Why href=“#” is High Priority than onclick

问题

I usualy found the following code:

<a href="#" onclick="func();return false">click</a>

but sometime my browser go to the top of the page?

Why href="#" is High Priority than onclick?

回答1:

It isn't higher priority. The onclick fires and then the browser follows the link.

If you don't return false (note spelling) or func throws an error (thus not reaching the return statement) the event won't be canceled.

(As fallbacks for if the JS fails or is disabled go, however, a link to the top of the page is really sucky. Progressive enhancement is the way forward.)

回答2:

If the only reason you want to have a href value is to enable the hand cursor, you can use css style instead:

<a style="cursor:pointer;" onclick="func();return false">click</a>
