利用js在asp.net中实现左导航页的隐藏
作者:dotsharp 2004.12.15
我们在csdn论坛上的左上角能够看到导航栏的功能,下面就模拟该功能,
利用js在asp.net中作一个简单的无刷新的左导航栏隐藏功能.
首先,作一个框架页,我们取名 main.aspx
<!-- main.aspx 主要代码 -->
<script>
document.write("<frameset rows='54,28,*,19' frameborder='no' border='0' framespacing='0'>");
document.write("<frame src='title.aspx' name='topframe' scrolling='no' noresize>");
document.write("<frame src='bar.aspx' name='mainnaviframe' scrolling='no'>");
<!-- left.aspx是导航页 ,menuswitch.aspx是交互的按钮页 -->
document.write("<frameset name='forum' cols='150,8,*' frameborder='no' border='0' framespacing='0'>");
document.write("<frame src='left.aspx' name='leftframe' scrolling='auto'>");
document.write("<frame src='menuswitch.aspx' name='swichframe' scrolling='no'>");
document.write("<frameset rows='100%,*' frameborder='no' border='0' framespacing='0'>");
document.write("<frame src='' name='mainframe' scrolling='no'>");
document.write("</frameset></frameset>");
document.write("<frame src='bottom.aspx' name='bottomframe' scrolling='no'></frameset>");
</script>
<!-- menuswitch.js 主要代码-->
var leftwin = true;
function changewin()
{
if(leftwin == true)
{
parent.forum.cols = "0,8,*";
parent.swichframe.menuswitch.innerhtml = "<a onclick='changewin();' style='cursor:hand;'><img src='images/arrowopen.gif' border='0'></a>";
leftwin = false;
}
else
{
parent.forum.cols = "150,8,*";
parent.swichframe.menuswitch.innerhtml = "<a onclick='changewin();' style='cursor:hand;'><img src='images/arrowclose.gif' border='0'></a>";
leftwin = true;
}
}
<!-- menuswitch.aspx 主要代码 -->
<table height="100%" cellspacing="0" cellpadding="0" width="8" background="images/middlebg1.gif"
border="0">
<tr>
<td onclick="changewin();" style="cursor:hand;" id="menuswitch" align="center">
<img id="image1" src="images/arrowclose.gif" border="0" />
</td>
</tr>
</table>
以上功能并不完善,只能起到抛砖引玉的作用,欢迎网友与我交流.
