javascript - 在屏幕中心启动 Facebook 共享弹出窗口

Question

以下代码运行良好并在屏幕上启动 facebook 弹出窗口，但此弹出窗口未居中。

<script type="text/javascript">
    function fbs_click() {u=location.href;t=document.title;window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),'sharer','toolbar=0,status=0,width=626,height=436');return false;}
</script>

<a href="http://www.facebook.com/share.php?u=<full page url to share" onClick="return fbs_click()" target="_blank" title="Share This on Facebook"><img src="images/facebookimage.jpg" alt="facebook share"></a>

这是一个居中弹出窗口的脚本:

<script type="text/javascript">
    function MyPopUpWin(url, width, height) {
        var leftPosition, topPosition;
        //Allow for borders.
        leftPosition = (window.screen.width / 2) - ((width / 2) + 10);
        //Allow for title and status bars.
        topPosition = (window.screen.height / 2) - ((height / 2) + 50);
        //Open the window.
        window.open(url, "Window2",
        "status=no,height=" + height + ",width=" + width + ",resizable=yes,left="
        + leftPosition + ",top=" + topPosition + ",screenX=" + leftPosition + ",screenY="
        + topPosition + ",toolbar=no,menubar=no,scrollbars=no,location=no,directories=no");
    }
</script>

如何更新第一个脚本，使其与第二个脚本结合使用，从而使弹出窗口在屏幕中央启动？

看看这是否适合你:

<script type="text/javascript">
function fbs_click(width, height) {
    var leftPosition, topPosition;
    //Allow for borders.
    leftPosition = (window.screen.width / 2) - ((width / 2) + 10);
    //Allow for title and status bars.
    topPosition = (window.screen.height / 2) - ((height / 2) + 50);
    var windowFeatures = "status=no,height=" + height + ",width=" + width + ",resizable=yes,left=" + leftPosition + ",top=" + topPosition + ",screenX=" + leftPosition + ",screenY=" + topPosition + ",toolbar=no,menubar=no,scrollbars=no,location=no,directories=no";
    u=location.href;
    t=document.title;
    window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),'sharer', windowFeatures);
    return false;
}
</script>

<!-- Please change the width and height to suit your needs -->
