常用的40个网站制作技巧 <script src="http://blog.youkuaiyun.com/count.aspx?ID=1889771&Type=Rank" type="text/javascript"></script>
1. οncοntextmenu= "window.event.returnValue=false " 将彻底屏蔽鼠标右键 <table border οncοntextmenu=return(false)> <td> no </table> 可用于Table 2. <body onselectstart= "return false "> 取消选取、防止复制 3. οnpaste= "return false " 不准粘贴 4. οncοpy= "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. 网页将不能被另存为 <noscript> <iframe src= "/blog/*.html> "; </iframe> </noscript> 11. <input type=button value=查看网页源代码 οnclick= "window.location = "view-source: "+ "http://www.williamlong.info " "> 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) 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 " οnfοcus= "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 οnclick=hh1.Click()> <input type=button value=最大化 οnclick=hh2.Click()> <input type=button value=关闭 οnclick=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.οnkeydοwn=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: 1 solid #000000 "> </textarea> 20. <div> <span> & <layer> 的区别? <div> (division)用来定义大段的页面元素,会产生转行 <span> 用来定义同一行内的元素,跟 <div> 的唯一区别是不产生转行 <layer> 是ns的标记,ie不支持,相当于 <div> 21.让弹出窗口总是在最上面: <body οnblur= "this.focus(); "> 22.不要滚动条? 让竖条没有: <body style= "overflow:scroll;overflow-y:hidden "> </body> 让横条没有: <body style= "overflow:scroll;overflow-x:hidden "> </body> 两个都去掉?更简单了 <body scroll= "no "> </body> 23.怎样去掉图片链接点击后,图片周围的虚线? <a href= "# " onFocus= "this.blur() "> <img src= "/blog/logo.jpg " border=0> </a> 24.电子邮件处理提交表单 <form name= "form1 " method= "post " action= "mailto:****@***.com " enctype= "text/plain "> <input type=submit> </form> 25.在打开的子窗口刷新父窗口的代码里如何写? window.opener.location.reload() 26.如何设定打开页面的大小 <body οnlοad= "top.resizeTo(300,200); "> 打开页面的位置 <body οnlοad= "top.moveBy(300,200); "> 27.在页面中如何加入不是满铺的背景图片,拉动页面时背景图不动 <STYLE> body {background-image:url(/blog/logo.gif); background-repeat:no-repeat; background-position:center;background-attachment: fixed} </STYLE> 28. 检查一段字符串是否全由数字组成 <script language= "Javascript "> <!-- function checkNum(str){return str.match(//D/)==null} alert(checkNum( "1232142141 ")) alert(checkNum( "123214214a1 ")) // --> </script> 29. 获得一个窗口的大小 document.body.clientWidth; document.body.clientHeight 30. 怎么判断是否是字符 if (/[^/x00-/xff]/g.test(s)) alert( "含有汉字 "); else alert( "全是字符 "); 31.TEXTAREA自适应文字行数的多少 <textarea rows=1 name=s1 cols=27 onpropertychange= "this.style.posHeight=this.scrollHeight "> </textarea> 32. 日期减去天数等于第二个日期 <script language=Javascript> function cc(dd,dadd) { //可以加上错误处理 var a = new Date(dd) a = a.valueOf() a = a - dadd * 24 * 60 * 60 * 1000 a = new Date(a) alert(a.getFullYear() + "年 " + (a.getMonth() + 1) + "月 " + a.getDate() + "日 ") } cc( "12/23/2002 ",2) </script> 33. 选择了哪一个Radio <HTML> <script language= "vbscript "> function checkme() for each ob in radio1 if ob.checked then window.alert ob.value next end function </script> <BODY> <INPUT name= "radio1 " type= "radio " value= "style " checked> Style <INPUT name= "radio1 " type= "radio " value= "barcode "> Barcode <INPUT type= "button " value= "check " οnclick= "checkme() "> </BODY> </HTML> 34.脚本永不出错 <SCRIPT LANGUAGE= "JavaScript "> <!-- Hide function killErrors() { return true; } window.onerror = killErrors; // --> </SCRIPT> 35.ENTER键可以让光标移到下一个输入框 <input οnkeydοwn= "if(event.keyCode==13)event.keyCode=9 "> 问题点数:
id="Topic_Zone" style="HEIGHT: 4px" marginwidth="0" marginheight="0" src="/u/AD/Topic_Zone.aspx" frameborder="0" width="100%" scrolling="no" height="0">
发表于:2007-11-14 12:05:27 1 楼 得分:0 36. 检测某个网站的链接速度: 把如下代码加入 <body> 区域中: <script language=Javascript> tim=1 setInterval( "tim++ ",100) b=1 var autourl=new Array() autourl[1]= "www.njcatv.net " autourl[2]= "javacool.3322.net " autourl[3]= "www.sina.com.cn " autourl[4]= "www.nuaa.edu.cn " autourl[5]= "www.cctv.com " function butt(){ document.write( " <form name=autof> ") for(var i=1;i <autourl.length;i++) document.write( " <input type=text name=txt "+i+ " size=10 value= "/blog/测试中......> " =》 <input type=text name=url "+i+ " size=40> =》 <input type=button value=GO οnclick=window.open(this.form.url "+i+ ".value)> <br/> ") document.write( " <input type=submit value=刷新> </form> ") } butt() function auto(url) else b++ } function run(){for(var i=1;i <autourl.length;i++)document.write( " <img src=http:// "+autourl+ "/ "+Math.random()+ " width=1 height=1 οnerrοr=auto( "http:// "+autourl+ " ")> ")} run() </script> 37. 各种样式的光标 auto :标准光标 default :标准箭头 hand :手形光标 wait :等待光标 text :I形光标 vertical-text :水平I形光标 no-drop :不可拖动光标 not-allowed :无效光标 help :?帮助光标 all-scroll :三角方向标 move :移动标 crosshair :十字标 e-resize n-resize nw-resize w-resize s-resize se-resize sw-resize 38.页面进入和退出的特效 进入页面 <meta http-equiv= "Page-Enter " content= "revealTrans(duration=x, transition=y) "> 推出页面 <meta http-equiv= "Page-Exit " content= "revealTrans(duration=x, transition=y) "> 这个是页面被载入和调出时的一些特效。duration表示特效的持续时间,以秒为单位。transition表示使用哪种特效,取值为1-23: 0 矩形缩小 1 矩形扩大 2 圆形缩小 3 圆形扩大 4 下到上刷新 5 上到下刷新 6 左到右刷新 7 右到左刷新 8 竖百叶窗 9 横百叶窗 10 错位横百叶窗 11 错位竖百叶窗 12 点扩散 13 左右到中间刷新 14 中间到左右刷新 15 中间到上下 16 上下到中间 17 右下到左上 18 右上到左下 19 左上到右下 20 左下到右上 21 横条 22 竖条 23 以上22种随机选择一种 39.在规定时间内跳转 <META http-equiv=V= "REFRESH " content= "5;URL=http://www.williamlong.info "> 40.网页是否被检索 <meta name= "ROBOTS " content= "属性值 "> 其中属性值有以下一些: 属性值为 "all ": 文件将被检索,且页上链接可被查询; 属性值为 "none ": 文件不被检索,而且不查询页上的链接; 属性值为 "index ": 文件将被检索; 属性值为 "follow ": 查询页上的链接; 属性值为 "noindex ": 文件不检索,但可被查询链接; 属性值为 "nofollow ": 文件不被检索,但可查询页上的链接。 最大化窗口? <script language= "JavaScript "> <!-- self.moveTo(0,0) self.resizeTo(screen.availWidth,screen.availHeight) //--> </script> 解决问题:由于层与下拉框之间的优先级是:下拉框 > 层,因此在显示的时候,会因为优先级的次序而会出现如上问题。(如果几个元素都是层的话,我们可以通过层的 z-index 属性来设置)解决办法就是:给层中放一个优先级比下拉框更高的元素(iframe),从而解决此问题!具体解决代码如下: <div id= "menu " style= "position:absolute; visibility:hidden; top:20px; left:20px; width:100px; height:200px; background-color:#6699cc; "> <table> <tr> <td> item 1 </td> </tr> <tr> <td> item 2 </td> </tr> <tr> <td> item 3 </td> </tr> <tr> <td> item 4 </td> </tr> <tr> <td> item 5 </td> </tr> </table> <iframe src= "/blog/javascript:false " style= "position:absolute; visibility:inherit; top:0px; left:0px; width:100px; height:200px; z-index:-1; filter= 'progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0) '; "> </iframe> </div> <a href= "# " οnclick= "document.getElementById( 'menu ').style.visibility= 'visible ' "> menu </a> <form> <select> <option> A form selection list </option> </select> </form> 输入框也可以做的很漂亮了 <div align= "center "> <input type= "hidden " name= "hao " value= "yes "> 外向数: <input name=answer style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) "> 没回答的题数: <input name=unanswer id= "unanswer " style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) "> <br/> 总得分: <input name=score id= "score " style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) "> 结 论: <input name=xgjg id= "xgjg " style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) "> <br/> <br/> <input onClick=processForm(this.form) style= "FONT-FAMILY: 宋体; FONT-SIZE: 9pt " type=button value=查看结果 name= "button "> <input type= "reset " name= "Submit " value= "重做 "> </div> 注意:修改 <body> 为 <body οnlοad= "max.Click() "> 即为打开最大 化窗口,而如果改为 <body οnlοad= "min.Click() "> 就变为窗口一打开就最小化 <object id= "min " type= "application/x-oleobject " classid= "clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 "> <param name= "Command " value= "Minimize "> </object> <object id= "max " type= "application/x-oleobject " classid= "clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 "> <param name= "Command " value= "Maximize "> </object> </body> 页面自动刷新(说明) 当你做网页时,是不是有的时候想让你的网页自动不停刷新,或者过一段时间自动跳转到另外一个你自己设定的页面?其实实现这个效果非常地简单,而且这个效果甚至不能称之为特效。你只要把如下代码加入你的网页中就可以了。 1,页面自动刷新:把如下代码加入 <head> 区域中 <meta http-equiv= "refresh " content= "20 "> ,其中20指每隔20秒刷新一次页面. 2,页面自动跳转:把如下代码加入 <head> 区域中 <meta http-equiv= "refresh " content= "20;url=http://www.williamlong.info "> ,其中20指隔20秒后跳转到http://www.williamlong.info页面。 页面自动关闭 5000是指时间 <body onLoad= "setTimeout(window.close, 5000) "> 弹出窗口自动关闭 10秒后弹出窗口自动关闭 注意:在新的tan.htm的body中要加 <onLoad= "closeit() "> head <script language= "JavaScript "> <!-- var gt = unescape( '%3e '); var popup = null; var over = "Launch Pop-up Navigator "; popup = window.open( ' ', 'popupnav ', 'width=225,height=235,resizable=1,scrollbars=auto '); if (popup != null) { if (popup.opener == null) { popup.opener = self; } popup.location.href = 'tan.htm '; } // --> </script> <body> 注意:这段代码是在新建文件中的 <script language= "JavaScript "> function closeit() </script> 这个可不是 <iframe> (引用)呀。是直接调用的。以下代码加入 <body> 区域 <object type= "text/x-scriptlet " width= "800 " height= "1000 " data= "../index.htm "> </object>
