按button粘贴到text里
<SCRIPT>
var a="bbbb";
window.clipboardData.setData("text",a)
</SCRIPT>
到这里粘贴试试？<input type=text id=text1>
<button onclick="text1.value=window.clipboardData.getData('text')">Paste</button>
打印网页中的某一个区域
要打印的部分，前后各加个“<!--startprint-->”，“<!--endprint-->”，然后，写个按钮或者是什么的调用以下函数，比如：
<input type="button" name="aa" onclick="preview()">
<script language=javascript>
function preview() {
bdhtml=window.document.body.innerHTML;
sprnstr="<!--startprint-->";
eprnstr="<!--endprint-->";
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));
window.document.body.innerHTML=prnhtml;
window.print();
}
</script>
关闭窗口三种办法
方法一：window.close();
通常情况下：window.opener=null;window.close();都是可行的。
方法二：
<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
但在通常的网页中，结果是：“仅在HTML帮助中才有此功能”！
方法三：
<OBJECT id=WebBrowser classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2
height=0 width=0></OBJECT>
让标题动态
<script>
<!--
var tx = new Array (
"◇:::::::网页制作学习园地:::::::◇欢迎您!◇",
"◆欢迎大家光临网页制作学习园地网站!◆",
"◆大量供应网页制作教材,资料,源代码,网页制作软件,相关插件光盘!◆",
"◆最可怕的敌人，就是没有坚强的信念!◆",
"◆应该让别人的生活因为有了你的生存而更加美好!◆"
);
var txcount=5;
var i=1;
var wo=0;
var ud=1;
function animatetitle()
{
window.document.title=tx[wo].substr(0, i)+"_";
if (ud==0) i--;
if (ud==1) i++;
if (i==-1) {ud=1;i=0;wo++;wo=wo%txcount;}
if (i==tx[wo].length+10) {ud=0;i=tx[wo].length;}
// if (window.document.title.length < 20 ) window.document.title=window.document.title+"-";
// if (window.document.title.length == 20 ) window.document.title=window.document.title+"]";
// if (window.document.title.length == 21 ) setTimeout("window.document.title='Animierte Seitentitel '; ",1000);
parent.window.document.title=tx[wo].substr(0, i)+"_";
setTimeout("animatetitle()",100);
}
animatetitle();
// --></script><script language="JavaScript">
<!--
function MM_openBrWindow(theURL,winName,features) { //v2.0
window.open(theURL,winName,features);
}
//-->
</script>
有三个输入框, 前两个是输入数字的.第三个的内容是前两个的内容的和,第三个不能让人输入.也就是其它语言的 readonly 属性
<script>
function add(){
var a=parseInt(aa.value);
var b=parseInt(bb.value);
var c=a+b;
ye.value=c;
}
</script>
<input size=2 name=aa>+<input size=2 name=bb>=<input size=2 name=ye disabled> <input type=button value=add onclick=add()>
注册名字只能由中文或半角大小写字母或半角数字组成
注册名字只能由中文或半角大小写字母或半角数字组成
其他带有任何制表符号 例如"_","."，日文 空格 全角的都不通过
并且含有禁注册字符时会有对应的alert
<script language="JavaScript">
<!--
function JS_Test(str) {
if (str != '') {
if (str.match(/[^0-9a-zA-Z\u4E00-\u9FA5]/g,'')== null) { alert ("符合要求"); }
else { alert ("不符合要求"); }
}
}
//-->
</script>
<input name="txt">
<input type="button" value="判断注册是否合法" onClick="JS_Test(txt.value)">
只能输入数字正则
<input onKeyUp="value=value.replace(/\D+/g,'')">
只能输入中文正则
<input onKeyUp="value=value.replace(/[ -}]/g,'')">
隐去浏览器中当鼠标移到图片上跳出的工具栏
<img galleryimg="no">
或者
<head>
<meta http-equiv="imagetoolbar" content="no">
</head>
同一个页面多种超链接样式
<style>
a.c1{color=red}
a.c2{color=blue}
a.c3{color=orange}
</style>
<a href="/" class="c1">ahcuor1</a>
<a href="/" class="c2">ahcuor2</a>
<a href="/" class="c3">ahcuor3</a>
js动态给一个DIV插入一个表格
<div id="insertdiv">abc</div>
<script language="JavaScript">
<!--
insertdiv.innerText="";
var table1=document.createElement("<table border=1 width=500 bgcolor=black>");
table1.insertRow().insertCell().innerText="aaaaaaaaaaaaaaaa";
alert(table1.tagName);
document.getElementById("insertdiv").appendChild(table1);
//-->
</script>
让英文字符串超出表格宽度自动换行
word-wrap: break-word; word-break: break-all;
form问题
在一个form中只有一个input输入框的情况下...在这个input输入框中按enter的话，form就会被提交。如何避免这样的情况出现?
<form onsubmit="if(event.srcElement.name=='bb'){this.submit()}else{return false}">
<input name=a size=20>
<input type=button name=bb onclick="submit();">
</form>
CSS在文字下面加两横
<font style="border-bottom:4px double navy">huerreson</font>
<font style="border-bottom:1px solid navy;text-decoration:underline">huerreson</font>
<style>
.u2 { border-bottom:9px double navy;border-color:000000;text-decoration:underline;}
</style>
<span class='u2'>两横</span>
用回车提交表单
<body onLoad="form.txt.focus()">
<form name="form">
<input name="txt" size="100" value="Mouse点我提交，按Enter也提交" onClick="form.submit()" onKeyDown="if (event.keyCode==13)form.submit()">
</form>
让文字域里面的文字不可修改
禁用<input type="text" value="disabled" disabled>
不可修改<input type="text" value="readonly" readonly>
通过层来实现渐淡淡出
<script language="JavaScript1.2">
function makevisible(cur,which){
if (which==0)
cur.filters.alpha.opacity=100
else
cur.filters.alpha.opacity=50
}
</script>
<div style="width:200px;height:200px;filter:alpha(opacity=50);border:1px solid #000;background:#efefef" onMouseOver="makevisible(this,0)" onMouseOut="makevisible(this,1)">
ywicc.com
</div>
检查是否为首页
<HTML XMLNS:IE>
<HEAD>
<STYLE>
@media all {
IE\:HOMEPAGE {behavior:url(#default#homepage)}
}
</STYLE>
<SCRIPT>
function fnVerify(){
sQueryHome = oHomePage.isHomePage(oHomeHref.value);
alert(sQueryHome);
event.returnValue = false;
}
</SCRIPT>
</HEAD>
<BODY>
<IE:HOMEPAGE ID="oHomePage" />
<INPUT TYPE=text ID=oHomeHref VALUE="http://www.microsoft.com">
<INPUT TYPE=button VALUE="Verify" onclick="fnVerify()">
</BODY>
</HTML>
判断一个层是否被隐藏
判断一个层是否被隐藏？例如，如果某一个层是被隐藏的就弹出＂你好＂的新窗口
<div id="Layer1" style="position:absolute; width:200px; height:115px; z-index:1; display:none;">a</div>
<script language="JavaScript">
<!--
Layer1.style.display=="none"?alert("你好"):alert("hidden");
//-->
</script>
如何做网站中滚动的文字，还带超链接
<marquee direction=up scrollamount=2 onmouseover="this.stop();" onmouseout="this.start();" width=50>
<a href="http://www.chinaui.com">http://www.chinaui.com</a>
</marquee>
如何在javascript中使表单中的一个按钮无效
<form method=post action="" name="form1">
<input type="button" name="button1" value="51js.com">
</form>
<script language="JavaScript">
<!--
form1.button1.disabled=true;
//-->
</script>
刷新框架
我有一个框架网页，左右2个网页，现在我在主窗口（右页面）登陆后返回到主窗口页面，我如何让左边页面也能刷新呢？
<body onload="parent.leftFrame.location.reload();">
或者在页面的最后:
<script>
//leftFrame指左边框架的名字
parent.leftFrame.location.reload();
</script>
ID与name的区别
一个元素定义了id，引用该元素时直接用id属性，而name通常用在form中，且必须由document.form.***而来，也就是说，name属性定义的元素在脚本中是document对象的子对象。
我说不太清楚，反正这么个意思。
此外，ID标识在一个页面中原则上应该唯一，而name则不一定。
我要用文字做按扭提交表单，不用input，怎么做？
<form name="form1">
<a href="###" onclick="form1.submit()">提交</a>
</form>
图片reset表单
<form name=jie>
<input value="text">
<img src="http://be10.ods.org/51js/images/standard/report.gif"
onclick="document.jie.reset()"></form>

如何让iframe根据内容适应高度
请问如何让iframe根据内容适应高度
在第一次加载的时候就会自动根据内容适应高度
<iframe src="http://www.baidu.com" onload="this.height = this.document.body.offsetHeight;this.width=this.document.body.offsetWidth;"></iframe>
