Checkbox as3 function

问题

I have 16 checkboxes and I need to see which of them was selected. Is there a function that can do that ? I am able to do them with if() but it will be way to long thanks for the help !!

回答1:

Put your checkboxes in an array, then create a function to iterate over the array and see which box was selected (you can use "for each" and "if"). Add all selected ones to a new array and use this as the function's return value.

You should enumerate checkboxes with progressive index, so you can cycle them with a simple for. For example:

//Your checkboxes
var cb1:CheckBox = new CheckBox();
addChild(cb1);
var cb2:CheckBox = new CheckBox();
addChild(cb2);
var cb3:CheckBox = new CheckBox();
addChild(cb3);
var cb4:CheckBox = new CheckBox();
addChild(cb4);
var cb5:CheckBox = new CheckBox();
addChild(cb5);
...

private function getSelectedCb():Array
{
    var returnArray:Array = new Array();
    for(var i:uint = 1; i < 6; i++)
    { 
        var c:CheckBox = this["cb" + i] as CheckBox;
        if(c != null && c.selected)returnArray.push(c);
    }
    return returnArray;
}

Function getSelectedCb() return array containing all selected checkboxes.

I hope this could be usefull to you!
