为什么需刷新整个页面，才能跳转

我有一个用frameset框架的网页：
Default.aspx



<frameset rows="86px,*" cols="*" framespacing="0" frameborder="no" border="0" noresize="noresize"

    scrolling="no">

    <frame src="Top.aspx" name="topFrame" id="topFrame" framespacing="0" frameborder="no" border="0" noresize="noresize" scrolling="no"/>

    <frameset cols="220, *" frameborder="1" border="6" framespacing="1" bordercolor="#A1C7F9">

        <frame src="Left.aspx" name="leftFrame" id="leftFrame" frameborder="0" scrolling="auto"/>

        <frame src="Home.aspx" name="rightFrame" id="rightFrame" frameborder="0" />

    </frameset>

</frameset>

Top.aspx



<div style="text-align: left; margin-left: 480px;">

<span class="title_04" onclick="WinOpen('IData/IDataList.aspx', '', 'rightFrame');title_04_click(this);">情报List_Test Speed</span>

<!---------------------------------------------------->

<a class="title_04" href="IData/IDataList.aspx" target="rightFrame" onclick="title_04_click(this);" onfocus="this.blur();">情报List</a>                    

</div>



function title_04_click(obj) {

            //

            var nav_items = getElementsByClassName("title_04", null, "div");

            for (var i = 0; i < nav_items.length; i++) {

                var nav_item_lis = nav_items[i].getElementsByTagName("a");

                for (var j = 0; j < nav_item_lis.length; j++) {

                    if (nav_item_lis[j] == obj) {

                        nav_item_lis[j].setAttribute("selected", "true")

                        nav_item_lis[j].className = "title_04_click";

                    }

                    else {

                        nav_item_lis[j].setAttribute("selected", "false")

                        nav_item_lis[j].className = "title_04_a";

                    }

                }            }

        }
