//两个解决flash程序中使用快捷键与文本输入冲突的办法
//在flash程序中使用快捷键,就可能会和文本输入引起冲突,主要是用单个字母或者shift+字母键作为快捷键时的冲突,比如当设置字母a为一个功能的快捷方法,但是当你进行文本输入的时候如果输入a就会同时引发事件,当然这不是我们所希望的,下面的两种方法来避免这种情况的出现:

//方法一:
keylis = new Object();
Key.addListener(keylis);

keylis.onKeyDown = function() {
 var pathArr = Selection.getFocus().split(".");
 var foucs = _root;
 for (var i = 1; i<pathArr.length; i++) {
  foucs = foucs[pathArr[i]];
 }
 if (foucs instanceof TextField && fouse.type == "input") {
  trace(foucs);
  return;
 }
 
 if(Key.isDown(65))
 {
  //run...
 }
}


//方法二:
//这种方法比较简单,但不能判断焦点文本的类型为输入类型
if(Selection.getCaretIndex() >=0)
{
	return;
} 



//-----------------------------------------------
//flash trace 技巧
var x = "aa";
var y = "bb";
var z = "cc";
trace("x,y,z="+x+","+y+","+z);		//一般方法
trace("x,y,z="+[x, y, z]);		//技巧方法


//-----------------------------------------------
//在Flash裡面自行解譯資料時，使用現成的LoadVars class來解譯变量串

var str:String = "&var1=vcsvfi&var2=vnsjmkvs&";
var parser:LoadVars = new LoadVars();
parser.onData(str);
for (var i in parser) {
	trace("parser["+i+"] : "+parser[i]);
}
/*
parser[loaded] : true
parser[var2] : vnsjmkvs
parser[var1] : vcsvfi
*/

//-----------------------------------------------
// 变量高效利用写法
//PRIMITIVE STRING
a = "Hello World"	//调用点语法时先执行 new String("Hello World")

//OBJECT STRING
a = new String("Hello World")	//调用点语法时直接执行
