flex implementation code for traversing the contents of Object objects
I always thought that the only way to traverse Object is obj.name. I did a data comparison today and found out
var g2:Object = expensesAC.getItemAt(0); for(var i:Number=0;i<=23;i++){ if(g2["times"+i]=="0"){ num--; }else{ d2g+=g2["times"+i]; } }

This way, in fact, I feel that Object is very similar to HashMap in java, both have value pairs. .
Specific example:
private function init():void { //新建对象 var obj:Object = new Object(); //增加key-value obj["name"] = "liguoliang"; //格式: Object[key] = value obj["age"] = 25; //注意: key必须为String, value可以为任意类型 //使用for..in...遍历所有的key - value for(var k:String in obj) { trace("Key: " + k + " - value: " + obj[k]); } //使用for each..in遍历HashMap for each( var v:* in obj) { trace("value: " + v); } //删除一个key-value delete obj["age"]; //使用for..in...遍历所有的key - value for(var k:String in obj) { trace("Key: " + k + " - value: " + obj[k]); } }
