JS代码屏蔽F12,右键,粘贴,复制,剪切,选中,操作实例
屏蔽f12审查
<script> 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; } } </script>
屏蔽右键菜单
<script> 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; } } </script>
屏蔽粘贴
<script> 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; } } </script>
屏蔽复制
<script> 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; } } </script>
屏蔽剪切
<script> 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; } }<script>
屏蔽选中
<script> 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; } } </script>
这些代码获取你在某些特殊开发的场合你可以用到,但是你也只能用这个骗一下小白,哈哈! 我收藏的分享出来给大家!
