<IMG SRC="mypicture.jpg" HEIGHT="100px" WIDTH="100px" GALLERYIMG="false">
or
<head>
<meta http-equiv="imagetoolbar" content="no">
</head>

无提示关闭

function Close(){
var ua=navigator.userAgent
var ie=navigator.appName=="Microsoft Internet Explorer"?true:false
if(ie)
{
var IEversion=parseFloat(ua.substring(ua.indexOf("MSIE ")+5,ua.indexOf(";",ua.indexOf("MSIE "))))
if(IEversion< 5.5)
{
var str = '<object id=noTipClose classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">'
str += '<param name="Command" value="Close"></object>';
document.body.insertAdjacentHTML("beforeEnd", str);
document.all.noTipClose.Click();
}
else
{
window.opener =null;
window.close();
}
}
else
{
window.close()
}
}

取得控件得绝对位置

<script language="javascript">
function getoffset(e){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent)
{
t+=e.offsetTop;
l+=e.offsetLeft;
}
var rec = new Array(1);
rec[0] = t;
rec[1] = l;
return rec
}
</script>

最小化,最大化,关闭

<object id=min classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Minimize"></object>
<object id=max classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Maximize"></object>
<OBJECT id=close classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM NAME="Command" value="Close"></OBJECT>
<input type=button value=最小化 οnclick=min.Click()>
<input type=button value=最大化 οnclick=max.Click()>
<input type=button value=关闭 οnclick=close.Click()>

光标停在文字最后

<script language="javascript">
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart('character',e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type=text name=text1 value="123" οnfοcus="cc()">
