I'm trying to ignore Ctrl-C in my website but im stuck.

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>Untitled Document</title>
        <script language="javascript">
            function whichButton(event)
            {
                if (event.button==2)//RIGHT CLICK
                {
                    alert("Not Allow Right Click!");
                }

            }
            function noCTRL(e)
            {
                var code = (document.all) ? event.keyCode:e.which;

                var msg = "Sorry, this functionality is disabled.";
                if (parseInt(code)==17) //CTRL
                {
                    alert(msg);
                    window.event.returnValue = false;
                }
            }
        </script>
    </head>
    <body>
        <form method="">
            <strong>Not Allow Paste </strong><BR>
            <input type="text" value="" onMouseDown="whichButton(event)" onKeyDown="return noCTRL(event)"/>
        </form>
    </body>
</html>

我试过这段代码，但它只能忽略右键单击.

I tried this code, but it is can only ignore right click.

如何忽略Ctrl-C?

答

如果你的 body 标签添加了这些事件

if your body tag adds these events

<body oncontextmenu="return noMenu();" onkeydown="return noKeys(event);">

然后您在部分定义这些函数，您可以在上下文菜单被激活(右键单击)或在页面上按下键时执行操作.

and you then define these functions in your <head> section, you can take action when the context menu is activated (right click) or when keys are pressed on your page.

<script type="text/javascript">
function noMenu()
{
    alert("Not Allow Right Click!");
    return false;
}

function noKeys(event)
{
    if (event == null) event = window.event;
    // here you can check event.keyCode
    return false;
}
</script>
