javascript局部变量

<script language="JavaScript">
<!--
    function MyObject(){
        var _firstName; //对象局部变量
        this.name="";   //对象public变量

        if(arguments.length>0){
            this.name=arguments[0];
            _firstName=this.name.split(" ")[0];
        }

        this.getName=function(){
            return this.name;
        }

        this.getFirstName=function(){
            return _firstName;
        }
    }

    var obj =new MyObject("Electric Communities");
    alert("FullName:"+obj.getName()+"/nFirstName:"+obj.getFirstName());
//-->
</script>

私有变量一般加前缀_,所以编写自己的js时,变量避免使用_开头,以免与js内置变量冲突。
