asp.net常用的javascript经典例子
2Dropdownlist无刷新的例子。xml.
3例如文本验证!
4下面是一个单选按纽前台不刷新的例子.有好的就往上贴

42屏闭一些键：
43
44function KeyDown(){ //屏蔽鼠标右键、Ctrl+n、shift+F10、F5刷新、退格键
45 //alert("ASCII代码是："+event.keyCode);
46 if ((window.event.altKey)&&
47 ((window.event.keyCode==37)|| //屏蔽 Alt+ 方向键 ←
48 (window.event.keyCode==39))){ //屏蔽 Alt+ 方向键 →
49 alert("不准你使用ALT+方向键前进或后退网页！");
50 event.returnValue=false;
51 }
52 if ((event.keyCode==8) || //屏蔽退格删除键
53 (event.keyCode==116)|| //屏蔽 F5 刷新键
54 (event.keyCode==112)|| //屏蔽 F1 刷新键
55 (event.ctrlKey && event.keyCode==82)){ //Ctrl + R

66 window.showModelessDialog("about:blank","","dialogWidth:1px;dialogheight:1px");
67 return false;}
68}
691. oncontextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键
702. <body onselectstart="return false"> 取消选取、防止复制
713. onpaste="return false" 不准粘贴
724. oncopy="return false;" oncut="return false;" 防止复制；防止剪切
735. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标
