JavaScript或者Jqurey把控件id作为參数来调用

1.JavaScript把控件id作为參数调用

<script type="text/javascript">
        function xx(pmba)
        {
            document.getElementById(pmba).style.display = "block";
        }
    </script>

<div id="overlay">
        <input type="button" value="弹出A" onclick="xx('xa')" /><input type="button" value="弹出B" onclick="xx('xb')" />
    </div>
    <div class="win" id="xa">
       网页a</div>
       <div class="win" id="xb">窗体b</div>

2.这个弄了好一会儿，仅仅写一个Jqurey函数，通过调用不同的控件id作为參数就好了，開始不会啊。老出错

<script type="text/javascript" src="jQuery 2.0.3.js"></script>
    <script type="text/javascript">
        function ShowMsg(xdiv)//调用函数时，传入控件id
        {
            var box = 300;
            var th = $(window).scrollTop() + $(window).height() / 1.6 - box;
            var h = document.body.clientHeight;
            var rw = $(window).width() / 2 - box;
            $('#'+ xdiv).animate({ top: th, opacity: 'show', width: 600, height: 340, right: rw }, 500);//最主要就是这个<span style="color:#FF0000;">$('#'+ xdiv)</span>
            return false;
        }
        function CloseMsg(ydiv)
        {
            $("#"+ydiv).animate({ top: 0, opacity: 'hide', width: 0, height: 0, right: 0 }, 500);
        }
    </script>
