此代码显示谷歌地图，其中显示每个指针的一些事件信息。当许多事件在地图中显示时，需要放大。当我放大然后需要按ctrl +鼠标滚动。但我只想要鼠标滚动。我尝试使用gestureHandling：＆＃39;贪心＆＃39;
<p:gmap gestureHandling: "greedy"></p:gmap>
但不适合我
这是我使用primefaces gmap
的xhtml页面<ui:composition xmlns="http://www.w3.org/1999/xhtml"

答案 0 :(得分：1)
只需合并Center to the current position in a Primefaces gmap
中答案的第二段PF('mapWidgetVar').getMap();
仅来自page 239 in the PrimeFaces documentation返回the GMap JavaScript Map object以及来自3.25 api update answer中Change Google Maps v3 mapOptions object after load的评论
map.setOptions({gestureHandling: 'greedy'});
到
PF('geoMap').getMap().setOptions({gestureHandling: 'greedy'});
将上述行复制/粘贴到PrimeFaces Maps showcase上的开发者控制台中以查看其是否正常工作
另见：
