JS禁止查校验网页源代码_食物语辅助类练哪个好

查校验源代码的禁止几种计划：

1. 直接按F12
2. Ctrl+Shift+I查校验
3. 鼠标点击右键查校验
4. Ctrl+u=view-source:+url

以上的几种计划都可以查校验到网站的源代码 ，我们可以通过使用JavaScript来屏蔽掉这三种状态从而实现禁止查校验源代码效果 。查校

真正能实现源代码的验网页源屏蔽
，单纯的JS是不可能完全屏蔽的!这些脚本只能简易防止小白 ，对计算机老鸟、食物语黑科技阵容大神是无法作用的
。并且现在很多校验器自带有查校验网页源代码的功能。

二、屏蔽右键菜单

<span class="hljs-built_in">document</span>.oncontextmenu = <span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">event</span>)</span>{
<span class="hljs-keyword">if</span>(<span class="hljs-built_in">window</span>.event){
event = <span class="hljs-built_in">window</span>.event;
}<span class="hljs-keyword">try</span>{
<span class="hljs-keyword">var</span> the = event.srcElement;
<span class="hljs-keyword">if</span>(!((the.tagName == <span class="hljs-string">"INPUT"</span>&& the.type.toLowerCase() == <span class="hljs-string">"text"</span>)|| the.tagName == <span class="hljs-string">"TEXTAREA"</span>)){
<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
<span class="hljs-keyword">return</span><span class="hljs-literal">true</span>;

三 、屏蔽粘贴

<span class="hljs-built_in">document</span>.onpaste = <span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">event</span>)</span>{
<span class="hljs-keyword">if</span>(<span class="hljs-built_in">window</span>.event){
event = <span class="hljs-built_in">window</span>.event;
}<span class="hljs-keyword">try</span>{
<span class="hljs-keyword">var</span> the = event.srcElement;
<span class="hljs-keyword">if</span>(!((the.tagName == <span class="hljs-string">"INPUT"</span>&& the.type.toLowerCase() == <span class="hljs-string">"text"</span>)|| the.tagName == <span class="hljs-string">"TEXTAREA"</span>)){

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")){returnfalse;}returntrue;}catch (e){returnfalse;}}

四 、屏蔽复制

<span class="hljs-built_in">document</span>.oncopy = <span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">event</span>)</span>{
<span class="hljs-keyword">if</span>(<span class="hljs-built_in">window</span>.event){
event = <span class="hljs-built_in">window</span>.event;
}<span class="hljs-keyword">try</span>{
<span class="hljs-keyword">var</span> the = event.srcElement;
<span class="hljs-keyword">if</span>(!((the.tagName == <span class="hljs-string">"INPUT"</span>&& the.type.toLowerCase() == <span class="hljs-string">"text"</span>)|| the.tagName == <span class="hljs-string">"TEXTAREA"</span>)){
<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
<span class="hljs-keyword">return</span><span class="hljs-literal">true</span>;
}<span class="hljs-keyword">catch</span>(e){
<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
}
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")){returnfalse;}returntrue;}catch (e){returnfalse;}}
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")){returnfalse;}returntrue;}catch (e){returnfalse;}}

五 、屏蔽剪切

<span class="hljs-built_in">document</span>.oncut = <span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">event</span>)</span>{
<span class="hljs-keyword">if</span>(<span class="hljs-built_in">window</span>.event){
event = <span class="hljs-built_in">window</span>.event;

<span class="hljs-keyword">var</span> the = event.srcElement;
<span class="hljs-keyword">if</span>(!((the.tagName == <span class="hljs-string">"INPUT"</span>&& the.type.toLowerCase() == <span class="hljs-string">"text"</span>)|| the.tagName == <span class="hljs-string">"TEXTAREA"</span>)){
<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
<span class="hljs-keyword">return</span><span class="hljs-literal">true</span>;
}<span class="hljs-keyword">catch</span>(e){
<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
}
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")){returnfalse;}returntrue;}catch (e){returnfalse;}}
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")){returnfalse;}returntrue;}catch (e){returnfalse;}}

这种很适合小会谈网站，食物语作弊软件毕竟版权名贵，被别人随意copy行内容就不好了

六、屏蔽选中

<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
<span class="hljs-keyword">return</span><span class="hljs-literal">true</span>;
}<span class="hljs-keyword">catch</span>(e){
<span class="hljs-keyword">return</span><span class="hljs-literal">false</span>;
}
}
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")){returnfalse;}returntrue;} catch (e) {returnfalse;}}
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")){returnfalse;}returntrue;} catch (e) {returnfalse;}}
