<input type="text" oncut="return false" value="不能剪切,包括鼠标右键">
<input type="text" onpaste="return false" value="不能粘贴，包括鼠标右键">
在<body>标签中添加以下代码：
oncontextmenu='return false' 禁止右键
ondragstart='return false' 禁止拖动
onselectstart ='return false' 禁止选中
onselect='document.selection.empty()' 禁止选中
oncopy='document.selection.empty()' 禁止复制
onbeforecopy='return false' 禁止复制
onmouseup='document.selection.empty()'
扩展资料
示例代码如下：
<body leftmargin=0 topmargin=0 oncontextmenu='return false' ondragstart='return false' onselectstart ='return false' onselect='document.selection.empty()' oncopy='document.selection.empty()' onbeforecopy='return false' onmouseup='document.selection.empty()'>
在网页开发中，有些时候我们不想让用户去复制或者粘贴该网页的东西，那么下面的几个方法就非常有用了！
//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
}
} //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
}
} //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
}
} //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
}
} //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
} catch (e) {
return false
}
}
网页退出提示的方法：
window.onbeforeunload = function(event){event = event || window.event
event.returnValue = ' '
}
移动端中，屏蔽类似iphone的默认滑动事件用一下方法：
//禁用浏览器的默认滑动事件var preventBehavior = function(e) {
e.preventDefault()
}
// Enable fixed positioning
document.addEventListener("touchmove", preventBehavior, false)
