Backbone.js 主干视图和模板
如何从该模型或集合创建视图和模板?我可以用控制台记录我想要的数据。我被视图和模板部分卡住了。谢谢Backbone.js 主干视图和模板,backbone.js,view,Backbone.js,View,如何从该模型或集合创建视图和模板?我可以用控制台记录我想要的数据。我被视图和模板部分卡住了。谢谢 var Weather = Backbone.Model.extend({ urlRoot: "http://api.openweathermap.org/data/2.5/weather?q=New%20York&mode=json&units=imperial", initialize: function (response) { console.log(resp

首先,我可能会这样做:
var WeatherItemView = Backbone.View.extend({
template: _.template($('#weather-template').html()),
render: function () {
var content = this.template({
weather: this.model
});
this.$el.html(content);
return this;
}
});
var WeatherListView = Backbone.View.extend({
initialize: function () {
this.listenTo(this.collection, 'sync', this.render);
},
render: function () {
this.collection.each(function (weather) {
var subView = new WeatherItemView({
model: weather
});
this.$el.append(subView.render().$el);
}, this);
return this;
}
});
$(document).ready(function () {
var weathers = new WeatherCollection();
weathers.fetch(); // assuming its accessing an api endpoint.
var weathersView = new WeatherListView({
collection: weathers
});
$('body').html(weathers.render().$el);
});
<!-- template for one weather item view -->
<script id='weather-template' type="text/template">
<%= weather.escape('name') %>
</script>
var WeatherItemView=Backbone.View.extend({
模板:35;.template($('#天气模板').html()),
渲染:函数(){
var content=this.template({
天气:这是一款
});
这是.$el.html(内容);
归还这个;
}
});
var WeatherListView=Backbone.View.extend({
初始化:函数(){
this.listenTo(this.collection,'sync',this.render);
},
渲染:函数(){
此.集合.每个(功能(天气){
var子视图=新建WeatherItemView({
型号:天气
});
这个.el.append(subView.render().el);
},这个);
归还这个;
}
});
$(文档).ready(函数(){
var weathers=新的WeatherCollection();
weathers.fetch();//假设它正在访问api端点。
var weathersView=新WeatherListView({
收藏:weathers
});
$('body').html(weathers.render().$el);
});
