1、 Disable right click and copy

Method 1：

Add the following code to the page ：

Copy the code as follows :

<script language="Javascript"> 
document.oncontextmenu=new Function("event.returnValue=false"); 
document.onselectstart=new Function("event.returnValue=false"); 
</script>

Method 2：

Add the following code to ：

<body oncontextmenu="return false" onselectstart="return false">

<body oncontextmenu="event.returnValue=false" onselectstart="event.returnValue=false">

In essence , Method 2 With the method 1 It's the same .

Method 3：

If you only restrict replication , You can add the following code ：

2、 Make menu " file "－" Save as " invalid

If you just disable right clicking and selecting copy , Others can also use... In the browser menu " file "－" Save as " Copy files . In order to torture Shell failure , You can add the following code between and ：

Copy the code as follows :

<noscript> 
<iframe src="*.htm"></iframe> 
</noscript>

such , When a user saves a web page , Will appear " Can't save Web page " Error of .

in addition , You can also use event.preventDefault() To stop oncontextmenu() also onselectstart()

Copy the code as follows :

document.oncontextmenu=function(evt){
     
evt.preventDefault(); 
} 

document.onselectstart=function(evt){
     
evt.preventDefault(); 
};

Since you can prohibit , Then, of course, you can also enable it , Just reassign the event , It can be assigned to null, Or a string 、 Boolean values will do . Such as ：

Copy the code as follows :

document.oncontextmenu=""; 
document.onselectstart=true;
