An easier way is to add the following code to the <body> so that the left and right mouse buttons are invalidated.
topmargin= "0" oncontextmenu= "return false" ondragstart= "return false" Onselectstart = "return false" onselect= " Document.selection.empty () "oncopy=" Document.selection.empty () "onbeforecopy=" return false "onmouseup=" Document.selection.empty () "
1. Prevent web pages from being saved as: Add the following code after <body>:
<noscript>
<iframe src= "*.htm" ></iframe>
</noscript>
2. Prevents Web page content from being copied. Paste: Add the following code to <body>:
<body onmousemove=\hidemenu () \ oncontextmenu= "return false" ondragstart= "return false" Onselectstart = "return False "Onselect=" Document.selection.empty () "oncopy=" Document.selection.empty () "onbeforecopy=" return false "onmouseup=" Document.selection.empty () ">
