问题 I have RTRIM; how to make LTRIM one? public static function rtrim(string:String):String { return string.replace(/\s+$/,""); } 回答1: Wow, seriously? You're using regular expressions to remove a constant sequence of characters from the ends of a string? Really? I don't know Actionscript/Flex, but this isn't the way to go. After a quick google I found a solution which may or may not be more efficient. 回答2: public static function ltrim(string:String):String { return string.replace(/^\s+/,""); }

问题 I'm developing a Flex Air (desktop) application that loads images from the local filesystem into a TileList. The user will then be able to drag (copy) these images out of the list onto another control. I've finally got the images showing up correctly (and not disappearing after scrolling the TileList) but they seem to disappear from the TileList at the start of a drag operation. I come from a .NET background and am just learning AS3/Flex, so if you see me using any anti-patterns here, feel

Does someone comfortable with AS3 knows what's wrong here ? Thanks in advance =) 回答1: Inside the Flash IDE, try clicking the instance of your character that's not looping the way you want it to (and

问题 I need to get the value of a certain column in the selected row via AS3, how can I do this? It keeps returning null when I try grid.SelectedItem.text ... Thanks for the help! I need to be able to reference the column by name, in this case "ID". EDIT: Does this require an event or something? Shouldn't there be a method for this built in?
