• Is it bad practice to not assign a new object to a variable?

  - by Jeff

  Is it bad javascript practice to not assign a newly created object to a variable if you're never going to access it? For example: for(var i=0;i<links.length;i++){ new objectName(links[i]); } And again, I won't be accessing it, so there's no need for a variable to reference it.

• Can you get the size of the Flash object in Actionscript?

  - by futuraprime

  I'm working with a Flash movie and I'm trying to get the size of the player itself (i.e. the height and width Flash has to work with from the object/embed tag). As far as I can tell, Flash doesn't make this available to ActionScript. I'm able to use this.root.loaderInfo.width and this.root.loaderInfo.height to get the "intended" size of the flash movie (what's specified on export), but if the dimensions are different on the page, this isn't helpful.
