一、屏蔽F12审查元素
<script type="text/javascript"> document.onkeydown = function() { if(window.event && window.event.keyCode == 123) { alert("请尊重版权!"); event.keyCode = 0; event.returnValue = false; } if(window.event && window.event.keyCode == 13) { window.event.keyCode = 505; } if(window.event && window.event.keyCode == 8) { alert(str + "\n请使用Del键进行字符的删除操作!"); window.event.returnValue = false; } } </script>
二、禁用右键菜单
<body ondragstart="window.event.returnValue=false" oncontextmenu="window.event.returnValue=false" onselectstart="event.returnValue=false"></body>
三、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; } }
四、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; } }
五、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; } }
六、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; } }
