Javascript opening maximized window when unintended

Question

Hey. The following line was opening a 490x610 window, but after modifying some other code, it started to open up the full page new window. Any ideas as to why?

<a href="cart_display.php"
 onclick="window.open('uploader/upload_files.php?order_id=32063700',
 '','width=490,height=610')">Upload Here</a>

Answer 1

cart_display.php is going to open since you do not return false in your onclick handler. Doing this will prevent the default behavior of the onclick, which is to follow the href.
