]]>javaScript所能实现屏蔽功能总汇http://www.cnitblog.com/junhong-cai/articles/64564.html疯狂水车疯狂水车Tue, 09 Mar 2010 07:20:00 GMThttp://www.cnitblog.com/junhong-cai/articles/64564.htmlhttp://www.cnitblog.com/junhong-cai/comments/64564.htmlhttp://www.cnitblog.com/junhong-cai/articles/64564.html#Feedback0http://www.cnitblog.com/junhong-cai/comments/commentRss/64564.htmlhttp://www.cnitblog.com/junhong-cai/services/trackbacks/64564.html一、屏蔽键盘所有键
<script language="javascript">
<!--
function document.onkeydown(){
event.keyCode = 0;
event.returnvalue = false;
}
-->
</script>


二、屏蔽鼠标右键

　　在body标签里加上oncontextmenu=self.event.returnvalue=false　或者:
<script language="javascript">
<!--
function document.oncontextmenu()
{
return false;
}
-->
</script>

function nocontextmenu()
{
if(document.all) {
event.cancelBubble=true;
event.returnvalue=false;
return false;
}
}

或者:
<body onmousedown="rclick()" oncontextmenu= "nocontextmenu()">

<script language="javascript">
<!--
function rclick()
{
if(document.all) {
if (event.button == 2){
event.returnvalue=false;
}
}
}
-->
</script>


三、屏蔽 Ctrl+N、Shift+F10、F5刷新、退格键
<script language="javascript">
<!--
//屏蔽鼠标右键、Ctrl+N、Shift+F10、F5刷新、退格键
function window.onhelp(){return false} //屏蔽F1帮助
function KeyDown(){
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;
}

注：这还不是真正地屏蔽 Alt+ 方向键，因为 Alt+ 方向键弹出警告框时，按住 Alt 键不放，用鼠标点掉警告框，这种屏蔽方法就失效了。
if ((event.keyCode == 8) &&
(event.srcElement.type != "text" &&
event.srcElement.type != "textarea" &&
event.srcElement.type != "password") || //屏蔽退格删除键
(event.keyCode==116)|| //屏蔽 F5 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;}
}

　　另外可以用 window.open 的方法屏蔽 IE 的所有菜单
　　第一种方法：
window.open("http://www.qpsh.com", "qpsh","toolbar=no,location=no,directories=no,menubar=no,
scrollbars=no,resizable=yes,status=no,top=0,left=0")

　　第二种方法是打开一个全屏的页面：
window.open("你的.asp", "", "fullscreen=yes")
*/
//-->
</script>

四、屏蔽浏览器右上角“最小化”“最大化”“关闭”键
<script language=javascript>
function window.onbeforeunload()
{
if(event.clientX>document.body.clientWidth&&event.clientY<0||event.altKey)
{
window.event.returnvalue = "";
}
}
</script>

　　或者使用全屏打开页面
<script language="javascript">
<!--
window.open(http://www.qpsh.com,"qpsh","fullscreen=3,height=100, width=400,
top=0, left=0, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no,
status=no");
-->
</script>

　　注：在body标签里加上
onbeforeunload="javascript:return false"//使不能关闭窗口


五、屏蔽F5键
<script language="javascript">
<!--
function document.onkeydown()
{
if ( event.keyCode==116)
{
event.keyCode = 0;
event.cancelBubble = true;
return false;
}
}
-->
</script>


六、屏蔽IE后退按钮，在你链接的时候用
<a href="javascript:location.replace(url)">


七、屏蔽主窗口滚动条
　　在body标签里加上
style="overflow-y:hidden"


八、屏蔽拷屏,不断地清空剪贴板
　　在body标签里加上
onload="setInterval('clipboardData.setData(\'Text\',\'\')',100)"


九、屏蔽网站的打印功能
<style>
@media print {
* { display: none }
}
</style>


十、屏蔽IE6.0 图片上自动出现的保存图标
　　方法一：
<META HTTP-EQUIV="imagetoolbar" CONTENT="no">

　　方法二：
<img galleryimg="no">


十一、屏蔽页中所有的script
<noscrript></noscript>
