JavaScript类的使用，引用类型分析

1.JS代码

<script type="text/javascript" src="JSStyle/jquery-1.6.min.js"></script>
    <script type="text/javascript" language="javascript">
        $(function() {
                          

            $("#testYinyong").click(function() {
                var obj = new Object();
                obj.message = "yoyo"; //随便定义属性
                function f1(param) {
                    param = new Object(); //参数原始值被覆盖
                    param.message = "zhushao";
                }
                function f2(param) {
                    debugger;
                    param.message = "youzhu";
                }
                f1(obj);
                alert(obj.message);
                f2(obj);
                alert(obj.message);
            });
            //            document.write('The caption reads, "After the snow of \'97. Grandma\'s house is covered."');
        });
       

    </script>

2.HTML

<div>
        <input id="testFunClass" type="button" value="测试JS类" />
        <br />
        <input id="testYinyong" type="button" value="测试参数传递" />
