<script>
/*

function validatePassword (pw, options) {
// default options (allows any password)

// enforce custom regex/function rules
for (i = 0; i < o.custom.length; i++) {
rule = o.custom[i];
if (rule instanceof RegExp) {
if (!rule.test(pw))
return false;
} else if (rule instanceof Function) {
if (!rule(pw))
return false;

}
// great success!
return true;
}
var options = {

var password2 = "password#";

</script>
Here are the validation types supported out of the box. All are optional, which means that all passwords are allowed by default.
Minimum and maximum length.
Minimum n lowercase characters (a–z).
Minimum n uppercase characters (A–Z).
Minimum n combined a–z and A–Z characters.
Minimum n numeric characters (0–9).
Minimum n special characters (characters other than a–z, A–Z, and 0–9).
Ban particular words (tested case-insensitively).
Ban n-length character sequences (e.g. "abc", "XYZ", or "789", with a sequence length of 3; does not apply to special characters).
Ban n-length qwerty character sequences (e.g. "qwerty" or "asdf", with a sequence length of 4; does not apply to special characters).
Ban sequential, identical characters (e.g. "aa" or "!!").
Use custom regular expressions (tested using RegExp.prototype.test) and functions (the password is provided as the first argument, and a Boolean value is expected in return).
62、 文字横向滚动
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>向左滚动的文字特效JS代码</title>
</head>
<body>
<div id="demo" style="overflow:hidden;height:24px; line-height:24px;width:600px; border:1px solid #666; white-space:nowrap;">
<div id="demo1">
<a href="#">说明: </a> 这个向左滚动的文字特效JS代码比较简洁，代码量很少，你可以扩展一下， 你完全可以在这里定义图片或者图文结合等等形式，这是一个容器。 style="overflow:hidden;height:24px; line-height:24px;width:600px; border:1px solid #666; white-space:nowrap;" 这一段，向左滚动的文字特效需要这一段样式的配合，在这里宽、高、和white-space:nowrap （强制不换行）是必须的。
</div>
<div id="demo2"></div>
</div>
<script style="text/javascript">
var speed=40;//数值越大，速度越慢
var demo2=document.getElementById("demo2");
var demo1=document.getElementById("demo1");
var demo=document.getElementById("demo");
function MarqueeLeft(){
if(demo2.offsetWidth-demo.scrollLeft<=0) demo.scrollLeft-=demo1.offsetWidth;
else demo.scrollLeft++;
}
var MyMar=setInterval(MarqueeLeft,speed);
demo.onmouseover=function() {clearInterval(MyMar);}
demo.onmouseout=function() {MyMar=setInterval(MarqueeLeft,speed);}
</script>
</body>
</html>
63、 单击button或空白区都隐藏层
$(function()
{
var ibox = $("#ibox");
//功能：单击button显示层，单击 button 或者 空白区 都隐藏层
$("#ibutton").click(function(event)
{
event.stopPropagation(); //阻止冒泡
if(ibox.is(":hidden")) ibox.show(); //单击button显示层
else ibox.hide(); //单击button隐藏层
});
//单击空白区隐藏层
$(document).click(function(){$("#ibox").hide();});
});
其他思路：
$('body').not('p').click(function(){});
或者：
$('*:not(body)').click(function() { alert('clicked an item!'); return false; });
64、javascript删除元素节点
<script type="text/javascript">
function removeElement(_element){
var _parentElement = _element.parentNode;
if(_parentElement){
_parentElement.removeChild(_element);
}
}
</script>
<div><input onclick="removeElement(this)" type="text" value="点击移除该输入框" /></div>
65、getElementsByClassName
<script type="text/javascript">
/*
Developed by Robert Nyman, http://www.robertnyman.com
Code/licensing: http://code.google.com/p/getelementsbyclassname/
*/
var getElementsByClassName = function (className, tag, elm){
if (document.getElementsByClassName) {
getElementsByClassName = function (className, tag, elm) {
elm = elm || document;
var elements = elm.getElementsByClassName(className),
nodeName = (tag)? new RegExp("\\b" + tag + "\\b", "i") : null,
returnElements = [],
current;
for(var i=0, il=elements.length; i<il; i+=1){
current = elements[i];
if(!nodeName || nodeName.test(current.nodeName)) {
returnElements.push(current);
}
}
return returnElements;
};
}
else if (document.evaluate) {
getElementsByClassName = function (className, tag, elm) {
tag = tag || "*";
elm = elm || document;
var classes = className.split(" "),
classesToCheck = "",
xhtmlNamespace = "http://www.w3.org/1999/xhtml",
namespaceResolver = (document.documentElement.namespaceURI === xhtmlNamespace)? xhtmlNamespace : null,
returnElements = [],
elements,
node;
for(var j=0, jl=classes.length; j<jl; j+=1){
classesToCheck += "[contains(concat(' ', @class, ' '), ' " + classes[j] + " ')]";
}
try {
elements = document.evaluate(".//" + tag + classesToCheck, elm, namespaceResolver, 0, null);
}
catch (e) {
elements = document.evaluate(".//" + tag + classesToCheck, elm, null, 0, null);
}
while ((node = elements.iterateNext())) {
returnElements.push(node);
}
return returnElements;
};
}
else {
getElementsByClassName = function (className, tag, elm) {
tag = tag || "*";
elm = elm || document;
var classes = className.split(" "),
classesToCheck = [],

current,
returnElements = [],
match;
for(var k=0, kl=classes.length; k<kl; k+=1){
classesToCheck.push(new RegExp("(^|\\s)" + classes[k] + "(\\s|$)"));
}
for(var l=0, ll=elements.length; l<ll; l+=1){
current = elements[l];
match = false;
for(var m=0, ml=classesToCheck.length; m<ml; m+=1){
match = classesToCheck[m].test(current.className);
if (!match) {
break;
}
}
if (match) {
returnElements.push(current);
}
}
return returnElements;
};
}
return getElementsByClassName(className, tag, elm);
};
</script>
实例：
<select class="input_numbers" id="input_numbers" name="limitedList">
<option value="100">1-100</option>
<option value="200">101-200</option>
<option value="300">201-300</option>
<option value="400">301-400</option>
<option value="500">401-500</option>
<option value="600">501-600</option>
<option value="700">601-700</option>
<option value="800">701-800</option>
<option value="900">801-900</option>
<option value="1000">901-1000</option>
</select>
<script type="text/javascript">
var elementList = getElementsByClassName("input_numbers");
alert(elementList[0].options.length);
alert(elementList.length);
</script>
66、JavaScript验证URL正则
<script>
function checkURL(url){
if(url)
{
var strRegex = "^((https|http):\/\/)?"
+ "(((([0-9]|1[0-9]{2}|[1-9][0-9]|2[0-4][0-9]|25[0-5])[.]{1}){3}([0-9]|1[0-9]{2}|[1-9][0-9]|2[0-4][0-9]|25[0-5]))" // IP形式的URL- 199.194.52.184
+ "|"
+ "([0-9a-zA-Z\u4E00-\u9FA5\uF900-\uFA2D-]+[.]{1})+[a-zA-Z-]+)" // DOMAIN（域名）形式的URL
+ "(:[0-9]{1,4})?" // 端口- :80
+ "((/?)|(/[0-9a-zA-Z_!~*'().;?:@&=+$,%#-]+)+/?)$";
var re = new RegExp(strRegex);
//re.test()
return re.test(url);
}
}
</script>
67、背景高亮
jQuery.fn.highlight = function () {
$(this).each(function () {
var el = $(this);
$("<div/>")
.width(el.outerWidth())
.height(el.outerHeight())
.css({
"position": "absolute",
"left": el.offset().left,
"top": el.offset().top,
"background-color": "#ffff99",
"opacity": ".7",
"z-index": "9999999"
}).appendTo('body').fadeOut(1000).queue(function () { $(this).remove(); });
});
}
$("#target").highlight();
测试：http://jsfiddle.net/x2jrU/92/
68、点击链接滑动 Smooth Scrolling
$(function() {
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
|| location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top
}, 1000);
return false;
}
}
});
});
69、制造文字闪动效果
.sd{color: #000;}
.r{color:#F00;}
</style>
<script language="javascript" src="jquery.min.js"></script>
<script>
function changecolor(){
$("a.sd").toggleClass('r')
}
$().ready(function(){
setInterval(function(){ changecolor()},1000)
})
</script>
或者
<script language="javascript">
i=0
function changecolor()
{
$("A.sd").css("color",i==0?"#000":"red");
i==2?i=0:i++
}
$().ready(function(){
setInterval(function(){ changecolor()},500)
})
</script>
<a class="sd">闪动</a>
70、电子时钟 javascript date time clock
