这个作业是聪明和爱好讨论到半夜的成果,

var r = h=s="";
var shang = "爱好聪明为你加油!";
function sun(r, h) {
 return (2*Math.PI*r*r+2*Math.PI*r*h);
}
function myColor() {
 _root.ss.background = true;
 _root.ss.backgroundColor = 0x00FFFF;
 _root.ss.border = true;
 _root.ss.borderColor = 0xFF0000;
}
js.onRelease = function() {
 if (r == "" || h == "" || isNaN(r) || isNaN(h) || r<=0 || h<0) {
  s = "请输入正确的数据";
  myColor();
 } else if (h == 0) {
  s = Math.PI*r*r;
  myColor();
  _txt.text = shang;
 } else {
  s = sun(r, h);
  myColor();
  _txt.text = shang;
 }
};
qk.onRelease = function() {
 r = "";
 h = "";
 s = "";
 _root.ss.background = false;
 _root.ss.borderColor = 0x000000;
 _txt.text = "";
};
