<script src="js/jquery-1.6.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
    text();
});

function text(){
    var $text = $("#text");
    
    $text.mouseover(function(){
        $("body").attr({"onselectstart":"return true;","oncontextmenu":"return true;"})
    }).mouseout(function(){
        $("body").attr({"onselectstart":"return false;","oncontextmenu":"return false;"})
    })
}
</script>
</head>
<body onselectstart="return false;" oncontextmenu="return false;">

    <div class="main">
        <textarea id="text" name="" cols="" rows="" style="width:300px; height:200px"></textarea>
    </div>

</body>
</html>




我想实现的效果,一开始鼠标右键是屏蔽的,当鼠标移入文本框时鼠标右键就恢复,当鼠标移离文本框时鼠标右键就屏蔽,上面的代码IE8,9都行,就是IE7不行,请各位帮助看一下是什么原因,谢谢。
