一、屏蔽F12审查元素

<script type="text/javascript">
document.onkeydown = function() {
if(window.event && window.event.keyCode == ) {
alert("请尊重版权!");
event.keyCode = ;
event.returnValue = false;
}
if(window.event && window.event.keyCode == ) {
window.event.keyCode = ;
}
if(window.event && window.event.keyCode == ) {
alert(str + "\n请使用Del键进行字符的删除操作!");
window.event.returnValue = false;
} } </script>

二、禁用右键菜单

<body ondragstart="window.event.returnValue=false" oncontextmenu="window.event.returnValue=false" onselectstart="event.returnValue=false"></body>

三、屏蔽粘贴

document.onpaste = function (event){
if(window.event){
event = window.event;
}try{
var the = event.srcElement;
if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
return false;
}
return true;
}catch (e){
return false;
}
}

四、屏蔽复制

document.oncopy = function (event){
if(window.event){
event = window.event;
}try{
var the = event.srcElement;
if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
return false;
}
return true;
}catch (e){
return false;
}
}

五、屏蔽剪切

document.oncut = function (event){
if(window.event){
event = window.event;
}try{
var the = event.srcElement;
if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
return false;
}
return true;
}catch (e){
return false;
}
}

六、屏蔽选中

document.onselectstart = function (event){
if(window.event){
event = window.event;
}try{
var the = event.srcElement;
if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){
return false;
}
return true;
