一 实用且必用的小脚本代码:

脚本1：进入主页以后自动播放声音

脚本2：进入主页后自动最大话,省的去在自己单击了

<script> <BR>self.moveTo(0,0) <BR>self.resizeTo(screen.availWidth,screen.availHeight) <BR></script>

脚本3：显示现在时间的脚本

脚本4：显示最后修改时间的脚本

<script>document.write(document.lastModified)</script>

脚本5：设为首页,加为收藏，加入频道,启动outlook发信

 onclick="this.style.behavior="url(#default#homepage)";
this.setHomePage(http://10.13.31.90/~kayvin/);">">设为首页

onclick="window.external.AddFavorite(location.href,document.title);">加入收藏

加入频道

与我联系

 

脚本6：状态栏动态显示现在时间

<script> <BR>function see(){ <BR>window.setTimeout("see()",1000); <BR>today = new Date(); <BR>self.status = today.toString(); <BR>} <BR></script>

脚本7：关闭窗口的脚本

[关闭窗口]

脚本8：按下F12键,直接返回首页

<script>function look(){ <BR>if(event.keyCode==123){document.location.href=http://10.13.31.90/~kayvin/} <BR>} <BR>if(document.onkeydown==null) <BR>{document.onkeydown=look} <BR></script>

脚本9：后退,刷新,前进

 

脚本10：设定时间弹出窗口,4000=4秒,当然你可以自定义

<script>function l() <BR>{ <BR>window.open(" 10.13.31.90/~kayvin/ ","name","width=500,height=150,border=0") <BR>} <BR>setTimeout("l()",4000) </script>

 

二 鼠标旁边的提示信息,类似与163登录后的页面提示效果：

代码拷贝框
<a href="#" title="这是提示">tip</a> <script language="JavaScript"> //***********默认设置定义.********************* tPopWait=50;//停留tWait豪秒后显示提示。 tPopShow=5000;//显示tShow豪秒后关闭提示 showPopStep=20; popOpacity=99; //***************内部变量定义***************** sPop=null; curShow=null; tFadeOut=null; tFadeIn=null; tFadeWaiting=null; document.write("<style type='text/css'id='defaultPopStyle'>"); document.write(".cPopText { background-color: #F8F8F5;color:#000000; border: 1px #000000 solid;font-color: font-size: 12px; padding-right: 4px; padding-left: 4px; height: 20px; padding-top: 2px; padding-bottom: 2px; filter: Alpha(Opacity=0)}"); document.write(""); document.write("<div id='dypopLayer' style='position:absolute;z-index:1000;' class='cPopText'>"); function showPopupText(){ var o=event.srcElement; MouseX=event.x; MouseY=event.y; if(o.alt!=null && o.alt!=""){o.dypop=o.alt;o.alt=""}; if(o.title!=null && o.title!=""){o.dypop=o.title;o.title=""}; if(o.dypop!=sPop) { sPop=o.dypop; clearTimeout(curShow); clearTimeout(tFadeOut); clearTimeout(tFadeIn); clearTimeout(tFadeWaiting); if(sPop==null || sPop=="") { dypopLayer.innerHTML=""; dypopLayer.style.filter="Alpha()"; dypopLayer.filters.Alpha.opacity=0; } else { if(o.dyclass!=null) popStyle=o.dyclass else popStyle="cPopText"; curShow=setTimeout("showIt()",tPopWait); } } } function showIt(){ dypopLayer.className=popStyle; dypopLayer.innerHTML=sPop; popWidth=dypopLayer.clientWidth; popHeight=dypopLayer.clientHeight; if(MouseX+12+popWidth>document.body.clientWidth) popLeftAdjust=-popWidth-24 else popLeftAdjust=0; if(MouseY+12+popHeight>document.body.clientHeight) popTopAdjust=-popHeight-24 else popTopAdjust=0; dypopLayer.style.left=MouseX+12+document.body.scrollLeft+popLeftAdjust; dypopLayer.style.top=MouseY+12+document.body.scrollTop+popTopAdjust; dypopLayer.style.filter="Alpha(Opacity=0)"; fadeOut(); } function fadeOut(){ if(dypopLayer.filters.Alpha.opacity<popOpacity) { dypopLayer.filters.Alpha.opacity+=showPopStep; tFadeOut=setTimeout("fadeOut()",1); } else { dypopLayer.filters.Alpha.opacity=popOpacity; tFadeWaiting=setTimeout("fadeIn()",tPopShow); } } function fadeIn(){ if(dypopLayer.filters.Alpha.opacity>0) { dypopLayer.filters.Alpha.opacity-=1; tFadeIn=setTimeout("fadeIn()",1); } } document.onmouseover=showPopupText; </script>

 

三 如果文字过长,则将过长的部分变成省略号显示：

运行代码框
<div style="width: 120px; height: 50px; border: 1px solid blue; overflow: hidden; text-overflow:ellipsis"> <nobr>就是比如有一行文字，很长，表格内一行显示不下.</nobr> </div>

四 滚动的图片

运行代码框
<script language="javascript"> imgArr=new Array() imgArr[0]="<a href=# onmouseMove='javascript:outHover=true' onMouseover='javascript:outHover=true'

language="javascript">writeDivs();initDivPlace();</script>

五 接收键盘指令的脚本:

代码拷贝框
<script language="JavaScript"> <!-- var hotkey=97 var destination="http://www.wyev.com" if (document.layers) document.captureEvents(Event.KEYPRESS) function backhome(e){ if (document.layers){ if (e.which==hotkey) window.location=destination } else if (document.all){ if (event.keyCode==hotkey) window.location=destination } } document.onkeypress=backhome //--> </script> onkeydown="javascript:onenter();" function onenter(){ if(event.keyCode==13){ alert("回车"); } }

六 让你的文本链接渐隐渐显:

运行代码框
<meta name="Description" content=""> <script language="javascript" type="text/javascript"> startColor = "#671700"; // 定义链接颜色 endColor = "#D8D1C5"; // 定义要渐变到最后的颜色 stepIn = 17; stepOut = 23; /* 定义是否让所有的文本链接自动渐变，true为是，false为否 */ autoFade = true; /* 在这里定义css样式里的类class：fade，如果为true，那么你要将要渐变的链接上加上此fade样式 */ sloppyClass = false; hexa = new makearray(16); for(var i = 0; i < 10; i++) hexa[i] = i; hexa[10]="a"; hexa[11]="b"; hexa[12]="c"; hexa[13]="d"; hexa[14]="e"; hexa[15]="f"; document.onmouseover = domouseover; document.onmouseout = domouseout; startColor = dehexize(startColor.toLowerCase()); endColor = dehexize(endColor.toLowerCase()); var fadeId = new Array(); function dehexize(Color){ var colorArr = new makearray(3); for (i=1; i<7; i++){ for (j=0; j<16; j++){ if (Color.charAt(i) == hexa[j]){ if (i%2 !=0) colorArr[Math.floor((i-1)/2)]=eval(j)*16; else colorArr[Math.floor((i-1)/2)]+=eval(j); } } } return colorArr; } function domouseover() { if(document.all){ var srcElement = event.srcElement; if ((srcElement.tagName == "A" && autoFade) || srcElement.className == "fade" || (sloppyClass && srcElement.className.indexOf("fade") != -1)) fade(startColor,endColor,srcElement.uniqueID,stepIn); } } function domouseout() { if (document.all){ var srcElement = event.srcElement; if ((srcElement.tagName == "A" && autoFade) || srcElement.className == "fade" || (sloppyClass && srcElement.className.indexOf("fade") != -1)) fade(endColor,startColor,srcElement.uniqueID,stepOut); } } function makearray(n) { this.length = n; for(var i = 1; i <= n; i++) this[i] = 0; return this; } function hex(i) { if (i < 0) return "00"; else if (i > 255) return "ff"; else return "" + hexa[Math.floor(i/16)] + hexa[i%16];} function setColor(r, g, b, element) { var hr = hex(r); var hg = hex(g); var hb = hex(b); element.style.color = "#"+hr+hg+hb; } function fade(s,e, element,step){ var sr = s[0]; var sg = s[1]; var sb = s[2]; var er = e[0]; var eg = e[1]; var eb = e[2]; if (fadeId[0] != null && fade[0] != element){ setColor(sr,sg,sb,eval(fadeId[0])); var i = 1; while(i < fadeId.length){ clearTimeout(fadeId[i]); i++; } } for(var i = 0; i <= step; i++) { fadeId[i+1] = setTimeout("setColor(Math.floor(" +sr+ " *(( " +step+ " - " +i+ " )/ " +step+ " ) + " +er+ " * (" +i+ "/" + step+ ")),Math.floor(" +sg+ " * (( " +step+ " - " +i+ " )/ " +step+ " ) + " +eg+ " * (" +i+ "/" +step+ ")),Math.floor(" +sb+ " * ((" +step+ "-" +i+ ")/" +step+ ") + " +eb+ " * (" +i+ "/" +step+ ")),"+element+");",i*step); } fadeId[0] = element; } </script> <a href="">让你的文本链接渐隐渐显</a>

七 类似与QQ的好友/黑名单之类的树型菜单_极品:

运行代码框
<title> New Document </title> <meta name="Generator" content="EditPlus"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> <script> if (!document.getElementById) document.getElementById = function() { return null; } function initializeMenu(menuId, actuatorId) { var menu = document.getElementById(menuId); var actuator = document.getElementById(actuatorId); if (menu == null || actuator == null) return; //if (window.opera) return; // I'm too tired actuator.parentNode.style.backgroundImage = "url(/images/plus.gif)"; actuator.onclick = function() { var display = menu.style.display; this.parentNode.style.backgroundImage = (display == "block") ? "url(/images/plus.gif)" : "url(/images/minus.gif)"; menu.style.display = (display == "block") ?
