Javascript代码收藏大全

1. oncontextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键
<table border oncontextmenu=return(false)><td>no</table> 可用于Table

2. <body onselectstart="return false"> 取消选取、防止复制

3. onpaste="return false" 不准粘贴

4. oncopy="return false;" oncut="return false;" 防止复制

5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标

6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标

7. <input style="ime-mode:-Disabled"> 关闭输入法

8. 永远都会带着框架
<script language="javascript"></script>

9. 防止被人frame
<SCRIPT LANGUAGE=javascript></SCRIPT>

10. 网页将不能被另存为
<noscript><iframe src="/*.html>";</iframe></noscript>

11. <input type=button value=查看网页源代码

12.删除时确认
<a href="/`javascript:if"(confirm("确实要删除吗?"location="boos.asp?&areyou=删除&page=1"`>删

除</a>

13. 取得控件的绝对位置
//javascript
<script language="javascript">
function getIE(E){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent){
t =e.offsetTop;
l =e.offsetLeft;
}
alert("top=" t "/nleft=" l);
}
</script>

//VBScript
<script language="VBScript"></script>

14. 光标是停在文本框文字的最后
<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" onfocus="cc()">

15. 判断上一页的来源
javascript:
document.referrer

16. 最小化、最大化、关闭窗口
<object id=hh1 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Minimize"></object>
<object id=hh2 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Maximize"></object>
<OBJECT id=hh3 classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM NAME="Command" value="Close"></OBJECT>

<input type=button value=最小化 onclick=hh1.Click()>
<input type=button value=最大化 onclick=hh2.Click()>
<input type=button value=关闭 onclick=hh3.Click()>
本例适用于IE

<script>
function look(){
if(event.shiftKey)
alert("禁止按Shift键!"; //可以换成ALT　CTRL
}
document.onkeydown=look;
