Question

in html,

<a href="/shop/view-item.php" onclick="checklogin();">View Item</a>

As you know, the execution order is,

1) onclick javascript function, checklogin,
2) go to href link, and page refresh, /shop/view-item.php

And if you add ‘return false’ in onclick function’s foot,
href doesn’t work. so the page remain on the same page. The code is,

<a href="/shop/view-item.php" onclick="checklogin();return false;">View Item</a>

My question,
Can I control ‘return false’ effect?
If user do not log, I want to user remain the same page with alert logging request.
If user logged already, let him go the anchor’s link url.

Is it possible?

Answer 1

Make sure your checklogin() function will return true or false appropriately, then do the following:

<a href="/shop/view-item.php" onclick="return checklogin();">View Item</a>
