【问题描述】：
我创建了一个地图，当我在输入框中搜索地址时，我的标记没有移动到我的新位置。
我已经添加了这个想法，它会解决我的问题，但我想我不明白这个 sn-p 在做什么
var markers = [];
// Listen for the event fired when the user selects a prediction and retrieve
// more details for that place.
searchBox.addListener('places_changed', function() {
var places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
这是完整的 HTML：
