document.onkeydown = function(){ if(window.event && window.event.keyCode == 123) { alert("F12被禁用"); 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; } }
2、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; } }
3、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; } }
4、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; } }
5、屏蔽剪贴
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; } }
6、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; } }
