为什么点击鼠标右键没反应了??

//为什么鼠标右键不会的没反应，应该var url = "<%=request.getContextPath()%>/jsp/sbk_login_temp.jsp";
这个jsp中你禁止了右键
  
<script>
function func_onload() {
        var wpara = "top=0,left=0,width=1015px,height=690px,"
                  + "toolbar=no,location=no,directories=no,"
                  + "status=yes,menubar=no,scrollbars=no,"
                  + "resizable=no,copyhistory=no";
        var url = "http://www.sina.com.cn";
        window.open(url,"SBKWin",wpara);
        window.opener="top";
        if (window.name != "SBKWin") {
            window.close();
        }
    }
</script>
<body onload=func_onload()>
