js 常用操作保留
获取页面URL参数
function getQueryString(name) {
var reg =new RegExp("(^|&)"+ name +"=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r !=null) return unescape(r[2]); returnnull;
}
var reg =new RegExp("(^|&)"+ name +"=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r !=null) return unescape(r[2]); returnnull;
}
获取键盘输入值
通window.onload一样document.onkeydown只可以在一个页面中出现一次
document.onkeydown = function(event) {
var e = event || window.event || arguments.callee.caller.arguments[0];
if (e && e.keyCode == 13) {
FunPaging("Skip");
}
}
Winfrom获取系统的软键盘
调用系统中的osk.exe可执行程序
Process.Start(@"C:\WINDOWS\system32\osk.exe");
Process.Start("osk.exe");

JS 时间和毫秒数的相互转化
时间转化毫秒数
1>时间转换成毫秒数
var oldTime = (new Date("2012/12/25 20:11:11")).getTime(); //得到毫秒数
不是上面的格式需要转化，如var strdate="2012-12-25 20:11:11";
strdate=strdate.replace(/-/g,'/');
var oldTime=(new Date(strdate)).getTime();
得到的结果为时间戳。
其中strdate可以有的格式有 ：2010/03/04 2010/03/04 20:20 2010/03/04 20:20:20
2>毫秒数转化为时间
var oldTime = (new Date("2012/12/25 20:11:11")).getTime(); //得到毫秒数
var newTime = new Date(oldTime); //就得到普通的时间了
3> js 时间获取
var now = new Date(); //获取系统日期，即Sat Jul 29 08:24:48 UTC+0800 2006
var yy = now.getFullYear(); //截取年，即2006
var mo = now.getMonth() + 1; //截取月，即07 （系统中的月份为0~11，所有使用的时候要+1）
var dd = now.getDate(); //截取日，即29
//取时间
var hh = now.getHours(); //截取小时，即8
var mm = now.getMinutes(); //截取分钟，即34
var ss = now.getSeconds(); //获取秒
var yy = now.getFullYear(); //截取年，即2006
var mo = now.getMonth() + 1; //截取月，即07 （系统中的月份为0~11，所有使用的时候要+1）
var dd = now.getDate(); //截取日，即29
//取时间
var hh = now.getHours(); //截取小时，即8
var mm = now.getMinutes(); //截取分钟，即34
var ss = now.getSeconds(); //获取秒

网页禁止复制和拷贝，禁止按键，禁止网页另存为
//禁止鼠标右键 $(document).bind("contextmenu", function(e) { return false; }); //禁止键盘按键: <script type="text/javascript"> function key() { if (event.shiftKey) { window.close(); } //禁止Shift if (event.altKey) { window.close(); } //禁止Alt if (event.ctrlKey) { window.close(); } //禁止Ctrl return false; } document.onkeydown = key; </script> <!-- 禁止选中内容 --> <script type="text/javascript"> var omitformtags = ["input", "textarea", "select"] omitformtags = omitformtags.join("|") function disableselect(e) { if (omitformtags.indexOf(e.target.tagName.toLowerCase()) == -1) return false } function reEnable() { return true } if (typeof document.onselectstart != "undefined") document.onselectstart = new Function("return false") else { document.onmousedown = disableselect document.onmouseup = reEnable } </script> <!--禁止网页另存为： --> <noscript> <iframe src="/*"></iframe> </noscript> JS禁止网页复制和拷贝，只需要在body中加入部分代码即可 <body oncontextmenu="return false" onselectstart="return false" oncopy="return false">
1、禁止右键 看到那里大家一定会想，这招有很多人介绍过了，而且破解的方法也有很多。但我那里要说的是另一种方法，而且我试了很多方法都没有能破解。具体如下： <script> function stop(){ alert("禁止拷贝! \n\nProhibit copy!"); return false; } document.oncontextmenu=stop; </script> 你可以按右键、shift+F10和右ctrl左边的那个键试试！看能不能解。^_^</body> 2、屏蔽左键选定内容 我们已经禁了右键，但是人家还是可以用左键来选中文字来复制，通过下面屏蔽左键代码： <SCRIPT LANGUAGE=javascript> function click() { alert('禁止拷贝! \n\nProhibit copy!') } function click1() { if (event.button==2) {alert('禁止拷贝! \n\nProhibit copy!') }} function CtrlKeyDown(){ if (event.ctrlKey) {alert('禁止拷贝! \n\nProhibit copy!') }} document.onkeydown=CtrlKeyDown; document.onselectstart=click; document.onmousedown=click1; </SCRIPT> 3、禁止另存为 经过上面的两步好像你的源源代码已经安全了，但别忘了，别人还可以将你的界面保存下来，再慢慢解析。不过别担心，下面我们来解决这个问题。 在你要保密的网页中加入以下源代码： <noscript> <iframe src="*.htm"></iframe> </noscript> 4. 对于单张图片 同样可以禁止右键 <img src="http://www.yuzhiguo.com/logo.gif" oncontextmenu="event.returnValue=false" /> 引用：http://www.yuzhiguo.com/articleview.asp?id=183
JS URL中的加密和解密
一次项目中遇到的情况是，用js代码获取URL中的参数，参数中含有中文字符，然后再给网页中的标签赋值的时候，就会出现乱码的问题，
然后想到了先在网页转向时对URL加密，然后获取的时候进行解密的方法来解决
js url加密解密 js对文字进行编码涉及3个函数：escape,encodeURI,encodeURIComponent，相应3个解码函数：unescape,decodeURI,decodeURIComponent 1、 传递参数时需要使用encodeURIComponent，这样组合的url才不会被#等特殊字符截断。 例如：<script language="javascript">document.write('<a href="http://passport.baidu.com/?logout&aid=7&u='+encodeURIComponent("http://cang.baidu.com/bruce42")+'">退出</a>');</script> 2、 进行url跳转时可以整体使用encodeURI 例如：Location.href=encodeURI("http://cang.baidu.com/do/s?word=百度&ct=21"); 3、 js使用数据时可以使用escape 例如：搜藏中history纪录。 4、 escape对0-255以外的unicode值进行编码时输出%u****格式，其它情况下escape，encodeURI，encodeURIComponent编码结果相同。 引用：:http://www.cnblogs.com/zgaspnet/archive/2012/05/09/2491728.html
