Question

嗨，我是Vue的新手，我遇到了这个问题，当我更新位置时，它不会反映在子组件上。我使用了计算和观看功能，但仍然没有更新。原谅我，因为我对VueJS并不了解。

因此在我的代码中，我有location（计算的），它侦听绑定到localLocation的{{1}}（数据）。我使用方法project.location

更新位置

希望任何人都能提供帮助。这是我的代码如下：

setPlace()

显示地址和地图的模板

模板的最后一行，用于更新位置

  .google-maps-wrapper
    template(v-if="!location")
      f7-list.no-margin-top
        f7-list-button(title='Add Location' @click="isAutocompleteOpen = true")
    template(v-if="location")
      f7-list.no-margin(inline-labels no-hairlines-md)
        f7-list-item.short-text Address: {{ location.formattedAddress }}
      div
        gmap-map.main-map(ref="googleMap" :options="mapOptions" :center="location.position" :zoom="16" :map-type-id="mapTypeId")
          gmap-marker(:position="location.position" :clickable="false")

更新位置的脚本

  f7-list-item.item-button(v-for='(location, index) in suggestedLocations' :title="location.structured_formatting.main_text" :subtitle="location.structured_formatting.secondary_text" @click="updateLocation(location)")

初始页面尚无地址

添加位置后的实际输出

父数据更新时，VueJS子组件GMAP不会重新呈现
