I've done this like below.
1. In each Input field, check box, combo etc. I listen to the change
event like this
change="editData(event.target)"
2. I've got a global variable to hold info of all changed items
public var editedObjects:Array = new Array();
3. editData function
public function editData(obj:Object):void{
//check if event.target was already changed
var addData:Boolean = true;
//verify if editedObjects contains items
if (editedObjects.length>0)
{
for(var i:int = 0; i< editedObjects.length;
i++) {
//If object is found do not
add it again
if(editedObjects[i]==obj){
addData = false;
}
}
}
//If object is not found add it to array
if (addData){
editedObjects[editedObjects.length]=obj;
}
//change parameters of selected object to show to
user which fields has been changed
obj.setStyle('backgroundColor', 0xFFCCCC);
obj.setStyle('borderColor', 0xFF99CC);
obj.setStyle('borderThickness',2);
obj.setStyle('color',0x993300);
obj.setStyle('fontWeight','bold');
}
4. If editedObjects.length>0 then there are changes.
editedObjects contains an array with references to all changed items.
You may loop the array and do what ever you wish with the changed
items.
Hope this helps.
