自动滚动的问题...

<textarea onpropertychange="this.scrollTop = this.scrollHeight" rows=3></textarea>

解决方案 »

  1.   

    iframe、frame可以用window.scrollTo(0,document.body.scrollHeight)，或者设置document.body.scrollTop=document.body.scrollHeight
      

  2.   

    <html>
    <head>
    <title>系统一览图</title>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <script language="JavaScript">
    <!--
    function scrolltop(){
    alert(document.body.scrollHeight);
    alert(document.body.clientHeight);
    document.body.scrollTop =document.body.scrollHeight- document.body.clientHeight;
    }
    //-->
    </script></head><body onLoad="scrolltop()">
    <script language="JavaScript">
    <!--
    var timer=false;
    document.ondblclick=scrollscreen;
    function scrollscreen(){
    var bdy=document.body;
    if(bdy.clientHeight+bdy.scrollTop>=bdy.scrollHeight){
    alert("already bottom! refresh now!");
    window.location.reload();
    return ;
    }
    bdy.scrollTop += 200;
    window.setTimeout(scrollscreen,500);
    }
    for(var i=0;i<800;i++)
    document.write("&nbsp;"+i+"<br>");
    //-->
    </script>
    </body></html>
