我有一些企业，我想在地图上画它们
我构建了函数setupMap（x，y），因为x是纬度，y是经度。
出于某种原因，它不会绘制任何东西。
当我点击show map按钮时：
<a onclick="setupMap('33.23478899909723', '35.57791471481323')" href='#showMap' data-inline='true' data-mini='true' data-role='button' data-rel='popup' data-position-to="window" data-transition="pop" >Show on map</a>
jQuery 移动对话框将打开，但未绘制任何内容。（甚至不是ccc）
应该绘制地图。

问题出在哪里？
您的地图div （id="heresTheMap"） 没有大小。
<div id="heresTheMap" style="height:500px;width:500px;">ccc</div>
