[HTML,JS禁止鼠标右键、禁止全选、复制、粘贴的方法]
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 onmousemove=/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()">
