我有一个 jsp 页面，其中包含另一个具有谷歌地图的 jsp 文件。但是当我访问父页面时，包含 jsp 文件的 div 正在获取 CSS 属性值“溢出：隐藏”，因此未显示地图。

父jsp的代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<link rel="stylesheet" href="<%=request.getContextPath()%>/css/style.css"  />
<script src="<%=request.getContextPath()%>/scripts/jquery-1.7.1.js" type="text/javascript"></script>

<script type="text/javascript">
function showHeatMap(){
  $('#heatDiv').toggle(true);
  $('#exportToCSVHeatMap').removeAttr('disabled');
  $('#dummyFenceMap').style.overflow="visible";
}
</script>
</head>

<body>
      <div id="heatMapDiv" style="display:none">
  heat map
      <div class="div-inline">
        <div class="div-daily">From Date (MM/DD/YYYY)</div>
        <input type="text" name="fromDateHM" id="datepicker4" class="input-inline" />
      </div>
      <div class="div-inline">
        <div class="div-daily">To Date (MM/DD/YYYY)</div>
        <input type="text" name="toDateHM" id="datepicker5" class="input-inline" />
      </div>

      <div id="buttonDiv">
        <input type="button" value="Show Heat Map" onclick="showHeatMap()" />
        <input type="button" value="Export To CSV" id="exportToCSVHeatMap" onclick="exportToCSVHeatMap()" disabled="disabled"/>
      </div> <!-- buttonDiv -->

      <div id="heatDiv" class="heat-map">
        <div class="div-daily">Heat Map</div>
        <div id="heatMap" style="display= block; width= 800px; height= 800px; "><jsp:include page="../jsp/dummyheatmap.jsp?name=test&id=1001"></jsp:include></div>
      </div> <!-- footTraffic -->
  </div> <!-- heatMapDiv -->

</body>
</html>

包含的jsp文件代码：

#heatMap div 的高度为 2 / 11px 并且溢出：隐藏。当我将溢出属性编辑为可见时，我看到了谷歌徽标和地图类型

谁能帮我我的代码有什么问题？

我通过向包含的 JSP 文件的 'dummyFenceMap' div 添加以下样式解决了这个问题。

style="border:1px solid #ff0000;position:relative; left:150px; top:10px; width:500px; height:400px;padding-left:15px;padding-right:15px"

添加上述样式后，地图将显示在嵌入的 JSP 文件中。

但是面临一个新的问题是——谷歌地图显示在 3/4 部分的 div 其余部分是空白的。但是当我调整浏览器窗口的大小时，谷歌地图会正确重绘。如何解决这个问题？
