[HTML,JS禁止鼠標右鍵、禁止全選、復制、粘貼的方法]
禁止鼠標右鍵、禁止全選、復制、粘貼;
oncontextmenu事件禁用右鍵菜單; js代碼:
document.oncontextmenu = function(){ event.returnValue = false;}// 或者直接返回整個事件document.oncontextmenu = function(){ return false;}
onselectstart事件禁用網頁上選取的內容; js代碼:
document.onselectstart = function(){ event.returnValue = false;}// 或者直接返回整個事件document.onselectstart = function(){ return false;}
oncopy事件禁用復制; js代碼:
document.oncopy = function(){ event.returnValue = false;}// 或者直接返回整個事件document.oncopy = function(){ return false;}
以上三種事件,如果只想單純的禁用鼠標右鍵,和復制粘貼,還可以將它們直接寫到HTML中的body上面;
<body oncontextmenu = "return false" ></body><body onselectstart = "return false" ></body><body oncopy = "return false" ></body>
禁用鼠標事件
document.onmousedown = function(e){ if ( e.which == 2 ){// 鼠標滾輪的按下,滾動不觸發 return false; } if( e.which==3 ){// 鼠標右鍵 return false; }}
禁用鍵盤中的ctrl、alt、shift
document.onkeydown = function(){ if( event.ctrlKey ){ return false; } if ( event.altKey ){ return false; } if ( event.shiftKey ){ return false; }}關鍵就在
oncontextmenu='return false' ondragstart='return false' onselectstart ='return false' onselect='document.selection.empty()' oncopy='document.selection.empty()' onbeforecopy='return false' onmouseup='document.selection.empty()'
一個更簡單的方法就是在<body>中加入如下的代碼,這樣鼠標的左右鍵都失效了. 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.禁止網頁另存為:在<body>后面加入以下代碼: <noscript> <iframe src="*.htm"></iframe> </noscript> 2.禁止網頁內容復制.粘貼:在<body>中加入以下代碼: <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()">
