如何在角度2+的引导程序模式中创建Google自动完成功能? [英] how to create google autocomplete in bootstrap modal in angular 2+?

问题描述

我正在使用通过以下方式创建的Google自动完成功能的角度Google Maps(agm).

I am using angular google maps (agm) i created google autocomplete by below way.

以html

  <input type="text" #pick id="address" class="form-control" [(ngModel)]="pickAddress" name="pickAddress" (ngModelChange)="pickAdd()" placeholder="Pick Up Address" onclick="return false" style="padding-left: 30px;border-radius: 25px;border: 1px solid #31708f;"

在Ts文件中:

pickAdd() {
  var autocomplete:any;
  var options = { componentRestrictions: {country: "IN"} };
  this. inputAddress = document.getElementById('address');
  autocomplete = new 
  google.maps.places.Autocomplete(this.inputAddress,options)
  google.maps.event.addListener(autocomplete, 'place_changed', ()=> {
    this.ngZone.run(() => {
      this.zoom=8;
      var place = autocomplete.getPlace();
      this.lat = place.geometry.location.lat();
      this.lng = place.geometry.location.lng();
      this.getGeoLocation(this.lat,this.lng);
    });
  });
}

css:

sebm-google-map {
    height: 300px;
}

如果我将上述代码置于引导程序模式下，则谷歌自动填充功能不起作用

if I put the above code in bootstrap modal, google autocomplete is not working

注意:

以上代码在没有引导模式的情况下正常工作(在正常情况下)

above code is working without bootstrap modal(in normal view)

推荐答案

它在普通视图下有效，并且在模式上无效，所以我想您的问题与 z-index 有关css属性.

It works in normal view, and it doesn't work in a modal, so I guess your issue is about z-index css property.

解决方案是将Google自动填充项的z-index设置为模式引导z-index的更多值:

The solution is to set the google autocomplete item's z-index more than the modal bootstrap z-index:

 .pac-container {
    z-index: 1054 !important;
 }

我确定这是问题所在，因为如果您按照 ngx-bootstrap的所有说明进行操作情态& AGM(您使用的旧版本是sebm-google-map)，您会注意到没有错误但仅不显示自动完成项.

I'm sure this is the problem because if you just followed all instruction for ngx-bootstrap modal & AGM (you're using an old version is sebm-google-map ) you will notice that there are no error but only the autocomplete item are not showing.

看一下我创建的这个插件(角度，ngx-bootstrap，angular-google-maps)，一切都很好:

Look in this plunker I created (angular, ngx-bootstrap, angular-google-maps) and all is fine:
