pop-up blocker

guess i finally understood how pop-up blockers are made..quite similiar to highligther.. using javascript to re-edit those html pages...

for instance, what the script would do is to parse through potential pops-up such as

windows.open("testpage.html","test page")

then it would alter the code
windows.open("null","null")


u can't possibly see the changes from the source (View/Source).. it will only show the original one,what being displayed is another version which you can't see the altered-code.

if you notice carefully, if you reverse the blocking function, then it would revisit the URL and refresh the HTML contents.

I haven't actually put down my finger to code a pop-up blocker.. but since my sister would accidentally got some pop-up blocker program installed to the house PC, it made me curious to find out more.

First of all, in higher end side, a pop-up blocker is program that blocks pop-up windows in Internet Explorer. It runs in system tray.

In lower end explanation, it is actually a daemon-thread program that is registered to IE as toolbars.

have a glimpse on what's happening for a google's popup blocker toolbar registered in the Windows' registry.
