程序代码：

<html>
<body>
<script>
var i;
function user(){
    this.name=[];
}

user.prototype.getname=function(){
    this.name[0]=prompt("enter your group name"," ");

    this.name[1]=prompt("enter your group name"," ");

    this.name[2]=prompt("enter your group name"," ");

    this.name[3]=prompt("enter your group name"," ");
    for(i=0;i<4;i++){
        while(this.name[i]==" "){
            this.name[i]=prompt("enter your group name"," ");
        }
    }
}
user.prototype.setname=function(){
    for(i=0;i<4;i++) document.write(this.name[i]);
}

var a=new user();
a.getname();
a.setname();
</script>
</body>
</html>

回复楼主 coutprintf

<html>
<body>
<script type="text/javascript">
  var i;
  function user() {
    this.name = new Array();
  }
  user.prototype.getname = function () {
    this.name[0] = prompt("enter your group name", " ");
    this.name[1] = prompt("enter your group name", " ");
    this.name[2] = prompt("enter your group name", " ");
    this.name[3] = prompt("enter your group name", " ");
    for (i = 0; i < 4; i++) {
      while (this.name[i] == " ") {
        this.name[i] = prompt("enter your group name", " ");
      }
    }
  }
  user.prototype.setname = function () {
    for (i = 0; i < 4; i++)
      document.write(this.name[i]);
  }
  var a = new user();
  a.getname();
  a.setname();
</script>
</body>
</html>

user.prototype.getname
user.prototype.setname
不需要带小括号
