Javascript 将值从余烬组件发送到父模板
我想将Javascript 将值从余烬组件发送到父模板,javascript,google-maps,ember.js,ember-components,ember-controllers,Javascript,Google Maps,Ember.js,Ember Components,Ember Controllers,我想将lat和lng从一个余烬组件传递到另一个余烬组件(g-map)。我的把手模板: {{!-- Index.hbs --}} <div class="jumbotron-outside"> <div class="jumbotron"> <h1 class="display-3">See The Weather Outside :)</h1> <p class="lead">This is a simple
lat
和lng
从一个余烬组件传递到另一个余烬组件(g-map
)。我的把手模板:
{{!-- Index.hbs --}}
<div class="jumbotron-outside">
<div class="jumbotron">
<h1 class="display-3">See The Weather Outside :)</h1>
<p class="lead">This is a simple forecast weather.</p>
<hr class="my-4">
<p>Just type everything bellow this input text to get all list of the city</p>
{{text-autocomplete}}
<p class="lead">
<button class="btn btn-primary btn-default" href="#" role="button" disabled={{isDisabled}}>Search</button>
</p>
</div>
{{g-map lat=lat lng=lng zoom=zoom}}
</div>
我想将text autocomplete
组件中的lat
和lng
值传递到g-map
组件,以便在谷歌地图中绘制标记
谁能解决这个问题(创建
index.js
控制器文件,并引入lat
、lng
和zoom
属性。您可以将此属性传递给组件文本自动完成和g-map
文本自动完成
此组件应向控制器发送操作,以更新的新值lat
和lng
由于双向绑定,它也将在其他位置自动更新
index.js控制器文件
import Ember from 'ember';
export default Ember.Controller.extend({
lat:'',
lng:'',
zoom:'',
actions:{
updateLatAndLng(lat,lng){
this.set('lat',lat);
this.set('lng',lng);
}
}
});
index.hbs
{{text-autocomplete lat=lat lng=lng updateLatAndLng=(action 'updateLatAndLng')}}
{{g-map lat=lat lng=lng zoom=zoom}}
text-autocomplete.js文件
import Ember from 'ember';
export default Ember.Component.extend({
didInsertElement() { //dom can be acessed here :)
var autocomplete = new google.maps.places.Autocomplete($('input')[0]);
var parent = this.$('input');
let _this = this;
google.maps.event.addListener(autocomplete, 'place_changed', function() {
var place = autocomplete.getPlace();
lat = place.geometry.location.lat();
lng = place.geometry.location.lng();
_this.sendAction('updateLatAndLng',lat,lng); //here we are sendin actions to controller to update lat and lng properties so that it will reflect in all the other places.
});
}
});
