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> 27. 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=测试中……> =》<input type=text name=url"+i+" size=40> =》<input type=button value=GO onclick=window.open(this.form.url"+i+".value)><br/>") document.write("<input type=submit value=刷新></form>") } butt() function auto(url){ document.forms[0]["url"+b].value=url if(tim>200) {document.forms[0]["txt"+b].value="链接超时"} else {document.forms[0]["txt"+b].value="时间"+tim/10+"秒"} b++ } function run(){for(var i=1;i<autourl.length;i++)document.write("<img src=http://"+autourl[i]+"/"+Math.random()+" width=1 height=1 onerror=auto(http://";;+autourl[i]+"')>")} run()</script> 28. 如何改变链接的鼠标形状 只需在链接上加上这一代码就行的了 或者跟上面的用CSS写也行 style="cursor:hand" style="cursor:crosshair" style="cursor:text" style="cursor:wait" style="cursor:move" style="cursor:help" style="cursor:e-resize" style="cursor:n-resize" style="cursor:nw-resize" style="cursor:w-resize" style="cursor:s-resize" style="cursor:se-resize" style="cursor:sw-resize" 以上代码你只需要加到连接或是页面的STYLE区里就可以实现鼠标多样化。 29.COOKIE脚本记录,有很大的用处。 function get_cookie(Name) { var search = Name + "=" var returnvalue = ""; if (documents.cookie.length > 0) { offset = documents.cookie.indexOf(search) if (offset != -1) { // if cookie exists offset += search.length // set index of beginning of value end = documents.cookie.indexOf(";", offset); // set index of end of cookie value if (end == -1) end = documents.cookie.length; returnvalue=unescape(documents.cookie.substring(offset, end)) } } return returnvalue; } function loadpopup(){ if (get_cookie('popped')==''){ openpopup() documents.cookie="popped=yes" } } 说明:以上是JS代码,请自己加起始符和结束符
