Closed 3 years ago. Improve this question I want the browser to send an alert saying "hello" when I put the following in my url: I have tried: javascript://(function(){alert('this is a bookmarklet';})() also tried it like: javascript:(function(){alert('this is a bookmarklet';})() I'm expecting an alert pop up and instead nothing is happening. Is it because I have an adblocker? does that disable popups like this. EDIT No, just disabled my adblocker and its still not working. I am annoyed because this seems like a really good way for me to actually make my javascript tinkering useful.
