Html代码

<pre class="html" name="code">function click(e) {
if (document.all) {
if (event.button==1||event.button==2||event.button==3) {
oncontextmenu='return false';
}
}
if (document.layers) {
if (e.which == 3) {
oncontextmenu='return false';
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
document.oncontextmenu = new Function("return false;")
var travel=true
var hotkey=17 /* hotkey即为热键的键值,是ASII码,这里99代表c键 */
if (document.layers)
document.captureEvents(Event.KEYDOWN)
function gogo(e)
{ if (document.layers) {
if (e.which==hotkey&&travel){
alert("操作错误.或许是您按错了按键!"); } }
else if (document.all){
if (event.keyCode==hotkey&&travel){ alert("操作错误.或许是您按错了按键!"); }}
}
document.onkeydown=gogo
把上面的代码另存为一个JS文件，然后在想实现此效果的页面调用即可！
===================================================
把下列代码放到<body></body>或者<head></head>之间
<script LANGUAGE="JavaScript">
function click() { if (event.button==2)
{alert('你好,右键已被禁止使用'); } } document.onmousedown=click
</script>
===================================================
禁止点击鼠标右键1：
<SCRIPT language=JavaScript>
<!--
file://锁鼠标右键和键盘CONTEXTMENU键
function click(e) {
if (document.all) {
if (event.button==2||event.button==3) { alert("欢迎光临寒舍，有什么需要帮忙的话，请与站长联系！谢谢您的合作！！！");
oncontextmenu='return false';
}
}
if (document.layers) {
if (e.which == 3) {
oncontextmenu='return false';
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
document.oncontextmenu = new Function("return false;")
// -->
</SCRIPT>
二、禁止点击鼠标右键2：
<script language="javascript">
function click() {
if (event.button==2) {
alert('欢迎光临寒舍，有什么需要帮忙的话，请与站长联系！谢谢您的合作！！！')
}
}
document.onmousedown=click
</script>
三、禁止鼠标右键3（推荐）：
<script language="JavaScript" type="text/JavaScript">
<!--
function MM_reloadPage(init) { //reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);
//-->
</script>
</head>
<body leftmargin=0 topmargin=0 onmousemove='HideMenu()' oncontextmenu="return false" ondragstart="return false" onselectstart
="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false"
onmouseup="document.selection.empty()">
