Converting a string into a CheckBox
I have a string which is ultimately the id of a CheckBox.
What I need to be able to do is to access the CheckBox's properties from the string
var myChec开发者_如何学JAVAkBox:Object; var myString:String;
myString = "checkbox_1"
myCheckBox = Object(myString); ?!?!
... and then I'd need to get to myCheckBox.selected, and myCheckBox.label etc
easier answer:
if(this.hasOwnProperty(myString) && this[myString] is CheckBox) {
myCheckBox = this[myString] as CheckBox
}
It's a bit of overcoding (since the as keyword will return a null if it's not a checkbox and you could better handle it that way with potentially less code), but that should do ya. Best of luck.
If you know what DisplayObjectContainer
(e.g. Sprite
, MovieClip
) the CheckBox
is inside you can use getChildByName.
Unfortunately if you are using Flex containers (like Group
) there is no function getElementByName()
. There is getElementAt so you could write a loop that iterates over all of a Groups
elements until it encounters one that matches the name you have.
