1、屏蔽右键菜单

document.oncontextmenu = 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;

}

}

2、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;

}

}

3、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;

}

}

4、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;

}

}

5、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;
