在本篇文章里小編給大家分享的是關(guān)于利用JS代碼屏蔽F12,右鍵,粘貼,復(fù)制,剪切,選中,操作，需要的朋友們學(xué)習(xí)下。

屏蔽f12審查

<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請使用Del鍵進(jìn)行字符的刪除操作！");
window.event.returnValue = false;
}
}
</script>

屏蔽右鍵菜單

<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>

屏蔽粘貼

<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>

屏蔽復(fù)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>

屏蔽選中

<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>

這些代碼獲取你在某些特殊開發(fā)的場合你可以用到,但是你也只能用這個(gè)騙一下小白,哈哈! 我收藏的分享出來給大家!
