checkbox

问题 I seem to be running into something really nasty: I have a form which contains a group of checkboxes. I have set up validation rules for my form, and just added an empty one for my checkbox group. However, after validating my form and giving an error, it only rechecks the last one in the group that was selected. This is just driving me nuts, since the user will never notice it was unchecked! for now, before building up the system, I just hardcoded the form to check if it works how I want it

问题 We have a fla, and under "Advanced Actionscript Settings", we have "Automatically declare stage instances" UNchecked. We then have a bunch of these declarations at the class level of our document class: public var spouseCheck:CheckBox; If I set spouseCheck.label = "blah" in my constructor, it does not work. However, if I set it later, (when another event happens), it does work. This implies that the checkbox is completely loaded at that time. How can I put an event listener on the checkbox so

问题 I've been bumbling my way through tutorials/forums in an attempt to figure out how update multiple methods using checkboxes. I need to be able to list my "events" and check or uncheck them if the date is available. I'd like to do this on one form. I know this is possible, but I'm finally coming here after failing to get it working. With the code I've posted I'm getting "Wrong Number of Arguments, 2 for 1" error. I've tried these info sources: http://railscasts.com/episodes/52-update-through
