15. 判斷上一頁的來源
javascript: document.referrer 16. 最小化、最大化、關(guān)閉窗口
<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=關(guān)閉 onclick=hh3.Click()> 本例適用于IE 17.屏蔽功能鍵Shift,Alt,Ctrl
<script> function look(){ if(event.shiftKey) alert("禁止按Shift鍵!"); //可以換成ALT CTRL } document.onkeydown=look; </script> 18. 網(wǎng)頁不會(huì)被緩存
<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.怎樣讓表單沒有凹凸感?
<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>的區(qū)別?
<div>(division)用來定義大段的頁面元素,會(huì)產(chǎn)生轉(zhuǎn)行 <span>用來定義同一行內(nèi)的元素,跟<div>的唯一區(qū)別是不產(chǎn)生轉(zhuǎn)行 <layer>是ns的標(biāo)記,ie不支持,相當(dāng)于<div> 21.讓彈出窗口總是在最上面:
<body onblur="this.focus();"> 22.不要滾動(dòng)條?
讓豎條沒有: <body style="overflow:scroll;overflow-y:hidden"> </body> 讓橫條沒有: <body style="overflow:scroll;overflow-x:hidden"> </body> 兩個(gè)都去掉?更簡單了 <body scroll="no"> </body> 23.怎樣去掉圖片鏈接點(diǎn)擊后,圖片周圍的虛線?
<a href="#" onFocus="this.blur()"><img src="/blog/logo.jpg" border=0></a> 24.電子郵件處理提交表單
<form name="form1" method="post" action="mailto:****@***.com" enctype="text/plain"> <input type=submit> </form> 25.在打開的子窗口刷新父窗口的代碼里如何寫?
window.opener.location.reload() 26.如何設(shè)定打開頁面的大小
<body onload="top.resizeTo(300,200);"> 打開頁面的位置<body onload="top.moveBy(300,200);"> 27.在頁面中如何加入不是滿鋪的背景圖片,拉動(dòng)頁面時(shí)背景圖不動(dòng)
<STYLE> body {background-image:url(/blog/logo.gif); background-repeat:no-repeat; background-position:center;background-attachment: fixed} </STYLE> 28. 檢查一段字符串是否全由數(shù)字組成
<script language="Javascript"><!-- function checkNum(str){return str.match(//D/)==null} alert(checkNum("1232142141")) alert(checkNum("123214214a1")) // --></script> 29. 獲得一個(gè)窗口的大小
document.body.clientWidth; document.body.clientHeight 30. 怎么判斷是否是字符
if (/[^/x00-/xff]/g.test(s)) alert("含有漢字"); else alert("全是字符"); 31.TEXTAREA自適應(yīng)文字行數(shù)的多少
<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight"> </textarea> 32. 日期減去天數(shù)等于第二個(gè)日期
<script language=Javascript> function cc(dd,dadd) { //可以加上錯(cuò)誤處理 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. 選擇了哪一個(gè)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" onclick="checkme()"> </BODY></HTML> 34.腳本永不出錯(cuò)
<SCRIPT LANGUAGE="JavaScript"> <!-- Hide function killErrors() { return true; } window.onerror = killErrors; // --> </SCRIPT> 35.ENTER鍵可以讓光標(biāo)移到下一個(gè)輸入框
<input onkeydown="if(event.keyCode==13)event.keyCode=9"> |
