Prohibit webpage right-click, copy, save as, View Source file and other functions to implement webpage source code protection. The following methods are summarized to implement simple web page protection. The specific code is as follows:

1. Disable right-click menu

<Script type = "text/javascrpt" language = "javascript"> // method 1 function noMenuOne () {alert ('prohibit right-click menu! '); Return false;} document. oncontextmenu = noMenuOne; // method 2 function noMenuTwo () {if (event. button = 2) {alert ('prohibit right-click menu! '); Return false ;}} document. onmousedown = noMenuTwo; </script>

2. Prohibit replication (Ctrl + C)

<Script type = "text/javascript" language = "javascript"> function noCopy () {alert ("do not use Ctrl + C for copying! "); Event. returnValue = false ;}</script> // <body oncopy =" noCopy () ">

3. Save as prohibited

<! -- Add code between <body> </body> --> <noscript> <iframe src = '*. htm'> </iframe> </noscript>

4. Disable caching
Disable caching by using the following HTML tag in the page:

<HEAD> <META http-equiv=Pragma content=no-cache> <META http-equiv=Cache-Control content=no-cache> <META http-equiv=Expires content=0> </HEAD>
