JavaScript禁止頁面操作的範例程式碼
本篇文章是對JavaScript禁止頁面操作的範例程式碼進行了介紹，需要的朋友可以過來參考下，希望對大家有所協助
單的JS禁止頁面右鍵菜單--避免網站資訊被盜用
代碼如下:
<script type="text/javascript">
function block(oEvent){
if(window.event)
oEvent=window.event;
if(oEvent.button==2)
alert("滑鼠右鍵不可用");
}
document.onmousedown=block;
</script>
網頁上禁止複製主要靠JavaScript來實現。
<BODY oncontextmenu="return false" onselectstart="return false"
ondragstart="return false" onbeforecopy="return false" oncopy=document.selection.empty() onselect=document.selection.empty()>
-----------------------------------------------
防止複製的js
-----------------------------------------------
代碼如下:
<SCRIPT language=JavaScript1.2>
function disableselect(e){
return false}
function reEnable(){return true
}
file://if IE4+
document.onselectstart=new Function ("return false")
file://if NS6
if (window.sidebar){
document.onmousedown=disableselect
document.onclick=reEnable
}
</SCRIPT>
<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>
-------------------------------------------------------
防止下載的js
-------------------------------------------------------
<noscript><iframe src=""></iframe></noscript>
--------------------------------------------------------
下面是防止右鍵的js:
代碼如下:
<script language="JavaScript">
<!--
if (window.Event)
document.captureEvents(Event.MOUSEUP);
function nocontextmenu() {
event.cancelBubble = true
event.returnValue = false;
return false;
}
function norightclick(e) {
if (window.Event){
if (e.which == 2 || e.which == 3)
return false;
}else{
if (event.button == 2 || event.button == 3){
event.cancelBubble = true
event.returnValue = false;
return false;
}
}
}
document.oncontextmenu = nocontextmenu; // for IE5+
document.onmousedown = norightclick; // for all others
//-->
</script>
<title>CSS禁止選擇和複製</title>
<meta http-equiv="content-Type" content="text/html;charset=gb2312">
<style>
body{
-moz-user-select:none;
hutia:expression(this.onselectstart=function(){return(false)});
}
</style>
</head>
<body>
這裡是網頁內容，試試您能不能複製？
</body>
</html>
應用執行個體：
代碼如下:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>JS控制頁面</title>
<script language="javascript" type="text/javascript">
//禁止使用者使用郵件（隱藏右鍵菜單）
document.oncontextmenu = function forbidRightKey() {
window.event.returnValue = false;
}
//禁止使用者使用郵件（提示使用者禁用右鍵）
function block() {
var oEvent;
if (window.event)
oEvent = window.event;
if (oEvent.button == 2)
alert("滑鼠右鍵不可用");
}
document.onmousedown = block;
//當使用者按鍵AltF4的時候，提示關閉視窗資訊
function altF4() {
if (window.event.altKey && window.event.keyCode == 115) {
window.close();
}
}
//alt 滑鼠左鍵 組成快速鍵 選中文字框中內容 調用方式<body onkeydown="altF4();" >
function getTxtSelect(eventControl) {
if (eventControl.altKey) {
document.getElementById("txt1").select();
}
}
function clearTxtByInput() {
document.getElementById("txtContent").value = "";
}
function FillTxtByInput() {
document.getElementById("txtContent").value = "輸入搜尋條件";
}
//禁用鍵盤上的某幾個鍵 調用onkeydown="ForbidKeys();"
function ForbidKeys() {
var content = window.event.keyCode;
if (content >= 65 && content <= 68) {
window.event.returnValue = false;
} else {
window.alert(content);
}
}
//禁止複製網頁內容 <body oncopy="forbidCopy();">
function forbidCopy() {
window.event.returnValue = false;
window.clipboardData.setData("Text", "");
alert("禁止複製網頁內容！");
}
//設定複製內容 附加 本網站的URL
function SetCopyContent() {
window.event.returnValue = false;
var content = document.title + "/r/n";
content += document.getElementById("txt1").value + "/r/n";
content += "本資源來自 " + this.location.href;
window.clipboardData.setData('Text', content);
alert("複製成功，請粘貼到你的QQ/MSN上推薦給你的好友");
}
//禁止重新整理F5 和Ctrl+F5
function ForbidFreshPage() {
if ((window.event.ctrlKey && window.event.keyCode == 116) || window.event.keyCode == 116) {
window.event.keyCode = 0;
window.event.returnValue = false;
}
}
document.onkeydown = ForbidFreshPage;
//屏蔽JS錯誤
function killErrors() {
return true;
}
window.onerror = killErrors;
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="txt1" type="text" value="Hello World!" onclick="getTxtSelect(event)"/>
<input type="button" value="複製文字框中的值" onclick="SetCopyContent();" />

<p>content</p>
