describeType() 是判斷型別的好工具

flash.utils.describeType() 是判斷型別的好工具
Flash AS3:

var a:Object = 123;
var b:Object = 1e-1;
var c:Object = {a:1,b:2};
var d:Object = [5,4,3];
var e:Object = 'sss';
trace(describeType(a).@name);
trace(describeType(b).@name);
trace(describeType(c).@name);
trace(describeType(d).@name);
trace(describeType(e).@name);

Output:

int
Number
Object
Array
String
