使用ember中的ajax渲染传单图视图上的坐标 [英] Rendering coordinates on leaflet map view using ajax in ember
问题描述
[]我正在尝试提供数据（通过 ajax的问题致电 json 文件的问题）一个手把模板和一个传单地图。使用我目前的设置，数据到达我的手柄模板很好，但不会将坐标数据呈现给传单图。我怀疑我错过了一些基本的 ember .js 难题有人请告知我吗？
[]I am trying to feed data (via an ajax call to a json file) to both a handlebars template and a leaflet map. With my current setup, the data reaches my handlebars template just fine, but doesn't render the coordinates data to the leaflet map. I suspect I am missing some basic piece of the ember.js puzzle. Would someone please advise me?

Ember：
App = Ember.Application.create();
App.Router.map(function() {
// put your routes here
});
App.IndexRoute = Ember.Route.extend({
model: function(){
return App.Item.all();
}
});
App.Item = Ember.Object.extend();
App.Item.reopenClass({
all: function() {
return $.getJSON("js/data/test_e.json").then(function(response) {
var items = [];
response.features.forEach( function (data) {
items.push( App.Item.create(data) );
});
return items;
});
}
});
App.MapView = Ember.View.extend({
didInsertElement: function () {
var map = L.map('map', {zoomControl: false}).setView([40.685259, -73.977664], 14);
L.tileLayer('http://{s}.tile.cloudmade.com/[redacted key]/[redacted id]/256/{z}/{x}/{y}.png').addTo(map);
console.log(this.get('content'));
//HERE IS WHERE I GET STUCK. I CAN OUTPUT THE JSON TO THE CONSOLE...
//BUT HOW DO I DRILL DOWN, AND ULTIMATELY...
//HOW DO I SEND THE VALUE OF THE "CENTER" KEY TO LEAFLET, i.e. L.Marker([jsonObject.center]).addTo(map);
}
});
App.IndexController =
Ember.Controller.extend({});
JSON：
{
"features": [
{
"headline": "Docker, the Linux container runtime: now open-source",
"center" : [40.685259, -73.977664]
},
{
"headline": "What's Actually Wrong with Yahoo's Purchase of Summly",
"center" : [40.685259, -73.977664]
}
]
}

视图由控制器支持，因此您可以执行 this.get（'controller'）来获取由你的集合支持的控制器，如果你想获取集合（这是不必要的，因为你可以迭代控制器）你可以做 this.get（ 'controller.model'）。
The view is backed by a controller, so you would do this.get('controller') to get the controller which is backed by your collection which if you wanted to get the collection (which isn't necessary since you can iterate the controller) you could do this.get('controller.model').
var controller = this.get('controller');
controller.forEach(function(item){
console.log(item.get('title'));
});
