我正在尝试使用google map api中的搜索框搜索地点.我正在使用Google Map Javascript api v3.当我尝试搜索某个地方时,它并不开心.任何人都可以帮我解决问题.这是html和javascript代码段.

<input id="pac-input" class="controls" type="text" placeholder="Search Box">
<div class="container" id="map-canvas" style="height:300px;"></div>没有place_changed-event了SearchBox(它是自动完成的事件).a的事件Searchbox被调用places_changed
有一个错字 palce
for( i = 0; palce = places[i]; i++)
目前还不清楚你想要实现什么,你在地方迭代(可能有多个地方)并将单个标记的位置设置到当前位置的位置.结果是标记总是位于返回结果的最后位置(对我来说没有意义).当您想要多个标记时,必须为每个位置创建单独的标记(并另外删除以前添加的标记),当您希望单个标记使用自动完成时.
