解决方案 »

  1.   

    如果是框架网页,左边树形菜单在左边框架,则可以:
    <frameset cols="*,*" frameborder="yes" border="1" framespacing="0" id="main">
      <frame src="c.htm" name="leftFrame" >
      <frame src="b.htm" name="mainFrame">
    </frameset>在一个事件中:
    top.main.cols='0,*'
      

  2.   

    给你一个实例:
    <HTML>
    <HEAD>
    <TITLE>xxxxxxxxxxxxxx</TITLE>
    <STYLE>
    .navPoint {
    COLOR: blue; CURSOR: hand; FONT-FAMILY: Webdings; FONT-SIZE: 9pt
    }</STYLE>
    <SCRIPT>
    function switchBar(){
    if (switchPoint.innerText==7){
    switchPoint.innerText=8
    document.all("frmTitle").style.display="none"
    }
    else{
    switchPoint.innerText=7
    document.all("frmTitle").style.display=""
    }
    }
    </SCRIPT>
    <BODY scroll=no style="MARGIN: 0px">
    <TABLE border=0 cellPadding=0 cellSpacing=0 height="100%" width="100%">
      <TBODY>
      <TR>
        <TD align=middle id=frmTitle noWrap vAlign=center name="frmTitle" width='6%'>
    <IFRAME frameBorder=0 id=BoardTitle name=BoardMenu scrolling=yes src="bbb.php" style="HEIGHT: 100%; VISIBILITY: inherit; WIDTH: 148px; Z-INDEX: 2"></IFRAME>
        <TD bgColor=#d2e8e6 onclick=switchBar() style="WIDTH: 10pt">
    <SPAN class=navPoint id=switchPoint title=关闭/打开菜单>7</SPAN>
    </TD>
        <TD style="WIDTH: 100%">
    <IFRAME frameBorder=0 id=frmright name=forum src="xxx.php" style="HEIGHT: 100%; VISIBILITY: inherit; WIDTH: 100%; Z-INDEX: 1"></IFRAME>
    </TD>
      </TR>
      </TBODY>
    </TABLE>
    </BODY>
    </HTML>
      

  3.   

    <frameset cols="*,*" frameborder="yes" border="1" framespacing="0" id="main">
      <frame src="c.htm" name="leftFrame" >
      <frame src="b.htm" name="mainFrame">
    </frameset>c.htm onclick事件中,这样写
    parent.frames[0].style.display="none"  //隐藏
    parent.frames[0].style.display="block"  //显示
