1. 将彻底屏蔽鼠标右键
oncontextmenu=”window.event.returnValue=false” < table border oncontextmenu=return(false)>< td>no< /table> 可用于 Table
2. 取消选取、防止复制
<span>< <span>body</span> <span>onselectstart</span>=<span>”return</span> <span>false</span>”></span>
3.JS不允许粘贴
onpaste=”return false”
4. JS防止复制
oncopy=”return false;” oncut=”return false;”
5. IE 地址栏前换成自己的图标
<span>< <span>link</span> <span>rel</span>=<span>”Shortcut</span> <span>Icon</span>” <span>href</span>=<span>”favicon.ico”</span>></span>
在文件的根目录放进去这个图片,后缀修改成ico就可以了
6.可以在收藏夹中显示出你的图标
<span>< <span>link</span> <span>rel</span>=<span>”Bookmark”</span> <span>href</span>=<span>”favicon.ico”</span>></span>
7.关闭输入法
<span>< <span>input</span> <span>style</span>=<span>”ime-mode:disabled”</span>></span>
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. 网页将不能被另存为
< noscript>< iframe src=https://www.jb51.net/*.html>< /iframe>< /noscript>
11. < input type=button value=查看网页源代码
onclick=”window.location = “view-source:”+ “””>
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”>< !– 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
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
17.屏蔽功能键 Shift,Alt,Ctrl
< script> function look(){ if(event.shiftKey) alert(“禁止按 Shift 键!”); //可以换成 ALT CTRL } document.onkeydown=look; < /script>
18. 网页不会被缓存
< META HTTP-EQUIV=”pragma” CONTENT=”no-cache”> < META HTTP-EQUIV=”Cache-Control” CONTENT=”no-cache, must-revalidate”> < META HTTP-EQUIV=”expires” CONTENT=”Wed, 26 Feb 1997 08:21:57 GMT”> 或者< META HTTP-EQUIV=”expires” CONTENT=”0″>
19.怎样让表单没有凹凸感?
< input type=text style=”border:1 solid #000000″>
或
< input type=text style=”border-left:none; border-right:none; border-top:none; border-bottom: solid #000000″>< /textarea>
20.< div>< span>&< layer>的区别?
