asp.net常用的javascript经典例子
Dropdownlist无刷新的例子。xml.
例如文本验证!
下面是一个单选按纽前台不刷新的例子.有好的就往上贴
<script language="javascript">
function SetButton()
{
if(document.all.rdoByHuman.checked==true)
{
document.all.cboHrPut.disabled = "";
document.all.cboAnswerHr.disabled = "";
document.all.cboGroup.disabled = true;
}
if(document.all.rdoByGroup.checked==true)
{
document.all.cboHrPut.disabled = true;
document.all.cboAnswerHr.disabled = true;
document.all.cboGroup.disabled = "";
}
}
</script>
<asp:RadioButton );
屏闭一些键：
function KeyDown(){ //屏蔽鼠标右键、Ctrl+n、shift+F10、F5刷新、退格键
//alert("ASCII代码是："+event.keyCode);
if ((window.event.altKey)&&
((window.event.keyCode==37)|| //屏蔽 Alt+ 方向键 ←
(window.event.keyCode==39))){ //屏蔽 Alt+ 方向键 →
alert("不准你使用ALT+方向键前进或后退网页！");
event.returnValue=false;
}
if ((event.keyCode==8) || //屏蔽退格删除键
(event.keyCode==116)|| //屏蔽 F5 刷新键
(event.keyCode==112)|| //屏蔽 F1 刷新键
(event.ctrlKey && event.keyCode==82)){ //Ctrl + R
event.keyCode=0;
event.returnValue=false;
}
if ((event.ctrlKey)&&(event.keyCode==78)) //屏蔽 Ctrl+n
event.returnValue=false;
if ((event.shiftKey)&&(event.keyCode==121)) //屏蔽 shift+F10
event.returnValue=false;
if (window.event.srcElement.tagName == "A" && window.event.shiftKey)
window.event.returnValue = false; //屏蔽 shift 加鼠标左键新开一网页
if ((window.event.altKey)&&(window.event.keyCode==115)){ //屏蔽Alt+F4
window.showModelessDialog("about:blank","","dialogWidth:1px;dialogheight:1px");
return false;}
}
1. oncontextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键
2. <body onselectstart="return false"> 取消选取、防止复制
3. onpaste="return false" 不准粘贴
4. oncopy="return false;" oncut="return false;" 防止复制；防止剪切
5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标
6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标
7. <input > 关闭输入法
8. 永远都会带着框架
<script language="javascript"><!--
if (window==top)
top.location.href="frames.htm"; file://frames.htm为框架网页
// --></script>
9. 防止被人frame
<SCRIPT LANGUAGE=javascript><!--
if (top.location!=self.location)
top.location=self.location;
// --></SCRIPT>
10. <noscript><iframe src=*.html></iframe></noscript> 网页将不能被另存为
使用鼠标拖动的层
<BODY BGCOLOR="#FFFFFF">
<div onmousedown="style.cursor='move';startMove(this)" onmouseup="style.cursor='auto'" >可以使用鼠标拖动</div>
<script language=javascript>
function startMove(objDiv)
{
document.attachEvent("onmousemove",moveDiv);
document.attachEvent("onmouseup",endMove);
document.attachEvent("onselectstart",selectNo);
document["moveDiv"] = objDiv;
document["startX"] = event.x;
document["startY"] = event.y;
document["oldX"] = objDiv.getBoundingClientRect().left;
document["oldY"] = objDiv.getBoundingClientRect().top;
}
function moveDiv()
{
//try{
var obj = document["moveDiv"];
if(obj)
{
var l = document["oldX"];//obj.getBoundingClientRect().left;//obj.style.left// = 100//(event.x-document["startX"]);
var t = document["oldY"];//obj.getBoundingClientRect().top;//obj.style.top// = 100//(event.y-document["startY"]);
obj.style.position = "absolute";
obj.style.left = l + (event.x-document["startX"]);
obj.style.top = t + (event.y-document["startY"]);
}
//}catch(e){endMove();}
}
function endMove()
{
document.detachEvent("onmousemove",moveDiv);
document.detachEvent("onmouseup",endMove);
document.detachEvent("onselectstart",selectNo);
document["moveDiv"] = null;
document["startX"] = null;
document["startY"] = null;
}
function selectNo()
{ return false; }
</script>
</BODY>
