jquery ui  的彈出窗體  dialog 。有時會出現當再次 開啟或在父窗體拖動時，

高度會發生變化。則需要進行設定。

open , dragstop 事件處理

  $('#showResult').dialog({ height: 320, width: 300, position: ['right'],
        open: function (event, ui) {
            // Height setter has no effect after init either
            $(this).dialog("option", "height", 320);

            // Width setter works after initialization too
            $(this).dialog("option", "width", 300);
        },
        dragStop: function (event, ui) {

            $(this).dialog("option", "height", 320);

            // Width setter works after initialization too
            $(this).dialog("option", "width", 300);
        }
    });
