Question

我尝试将setPanel（）添加到地点搜索和文字方向。但我无法做到。

我想一起添加这些选项。

我是google map api的新手。有谁可以帮助我？

这是我的代码

好的，当你使用谷歌FormElement时，你不必在输入元素中调用calcRoute（）。

只需使用以下代码即可。

1）Google表单提交：

    var places = searchBox.getPlaces();
    calcRoute(places[0].geometry.location);

2）calcRoute功能的第一个参数：

    var start = new google.maps.LatLng(places.A,places.F);

3）如果你想使用setpanel（）方法，只需将此代码放在directionsDisplay.setMap（map）;

下面

这将有效。

    directionsDisplay.setPanel(document.getElementById('panel'));
