常用JS

常用JS

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"><!-- if (window == top)top.location.href = "frames.htm"; //frames.htm为框架 网页 // --></script>

9. 防止被人frame <SCRIPT LANGUAGE=JAVASCRIPT><!-- if (top.location != self.location)top.location=self.location; // --></SCRIPT>

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

11. <input type=button value=查看网页源代码 onclick="window.location = \'view-source:\'+ \'http://www.csdn.net/\'">

12. 怎样通过asp的手段来检查来访者是否用了代理

<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then

response.write "<font color=#FF0000>您通过了代理服务器,"& _ "真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR") end if %>

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">

<!-- function getIE()

dim t,l,a,b

set a=document.all.img1

t=document.all.img1.offsetTop

l=document.all.img1.offsetLeft

while a.tagName<>"BODY"

set

a = a.offsetParent

t=t+a.offsetTop

l=l+a.offsetLeft

wend

msgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置"

end function -->

</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

asp: request.servervariables("HTTP_REFERER")

java script: document.referrer

16. 最小化、最大化、关闭窗口

<object id=hh1

classid="clsid:ADB 880A 6-D8FF-11CF-9377-00AA003B 7A 11">

<param name="Command" value="Minimize">

</object>

<object

id=hh2 classid="clsid:ADB 880A 6-D8FF-11CF-9377-00AA003B 7A 11">

<param name="Command" value="Maximize"></object>

<OBJECT id=hh3

classid="clsid:adb 880a 6-d8ff-11cf-9377-00aa003b 7a 11">

<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
