禁止鼠标右键、禁止全选、复制、粘贴;
oncontextmenu事件禁用右键菜单;
js代码:
document.oncontextmenu = function(){
event.returnValue = false;
}
// 或者直接返回整个事件
document.oncontextmenu = function(){
return false;
}
onselectstart事件禁用网页上选取的内容;
js代码:
document.onselectstart = function(){
event.returnValue = false;
}
// 或者直接返回整个事件
document.onselectstart = function(){
return false;
}
oncopy事件禁用复制;
js代码:
document.oncopy = function(){
event.returnValue = false;
}
// 或者直接返回整个事件
document.oncopy = function(){
return false;
}
以上三种事件,如果只想单纯的禁用鼠标右键,和复制粘贴,还可以将它们直接写到HTML中的body上面;
<body oncontextmenu = "return false" ></body>
<body onselectstart = "return false" ></body>
<body oncopy = "return false" ></body>
禁用鼠标事件
document.onmousedown = function(e){
if ( e.which == 2 ){// 鼠标滚轮的按下,滚动不触发
return false;
}
if( e.which==3 ){// 鼠标右键
return false;
}
}
禁用键盘中的ctrl、alt、shift
document.onkeydown = function(){
if( event.ctrlKey ){
return false;
}
if ( event.altKey ){
return false;
}
if ( event.shiftKey ){
return false;
}
}
关键就在
oncontextmenu='return false'
ondragstart='return false'
onselectstart ='return false'
onselect='document.selection.empty()'
oncopy='document.selection.empty()'
onbeforecopy='return false'
onmouseup='document.selection.empty()'
一个更简单的方法就是在<body>中加入如下的代码,这样鼠标的左右键都失效了.
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()"
1.禁止网页另存为:在<body>后面加入以下代码:
<noscript>
<iframe src="*.htm"></iframe>
</noscript>
2.禁止网页内容复制.粘贴:在<body>中加入以下代码:
<body
onm ousemove=/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()">
