所以我们都知道,一旦你发布你的图像,你就无法真正保护你的图像,但是对于那些非专业人士来说,它有点乐趣。我添加了一个脚本以防止右键单击并试图随机化有趣的消息......它无法正常工作。

脚本:

// BACKGROUND IMAGES
try {
  document.execCommand("BackgroundImageCache", false, true);
} catch(err) {}



// no right click
var message=["That doesn't belong to you!  Put the mouse down and no one gets hurt!";
             "Oh, you again.  We of the internet have chosen to defy you!";
         "How would you like it if I walked into your house and tried to help myself to     your furniture?";
         "Hey that tickles!"
         "Thief!  You are being directed to the...  nah just kidding. Enjoy!"]


function clickIE4(){
    if (event.button==2){
        alert(message);
        return false;
    }
}

function clickNS4(e){
    if (document.layers||document.getElementById&&!document.all){
        if (e.which==2||e.which==3){
            alert(message);
            return false;
        }
    }
}

if (document.layers){
    document.captureEvents(Event.MOUSEDOWN);
    document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
    document.onmousedown=clickIE4;
}

document.oncontextmenu=new Function("alert(message);return false")

我忘记了什么?它看起来应该有效。当我删除[和]并将其减少为一条消息时,该消息正常工作。它当我添加额外的并尝试随机化它以解决问题。

你警告整个阵列 如果您想要随机消息,您可以执行以下操作:

 var rn = Math.floor(Math.random() * message.length);
 alert(message[rn]);

这会从数组中的消息数中生成一个随机数。

Math.random
Math.floor
