Ember.js 是一個開源 JavaScript 框架,用於開發基於 Model-View-Controller (MVC) 架構的大型客戶端 Web 應用程序。 Ember.js是使用最廣泛的前端應用框架之一。它的目的是加速開發並提高生產力。目前,它被大量網站使用,包括 Square、Discourse、Groupon、Linked In、Live Nation、Twitch 和 Chipotle。
content 屬性用於轉發對象屬性。
用法:
ObjectProxy.create({content: value})
特性:
- value: 它是分配給內容的值。
安裝和運行 Ember.js 的步驟:
第 1 步:要運行以下示例,您需要有一個 ember 項目。要創建一個,您需要先安裝ember-cli。在終端中寫入以下代碼:
npm install ember-cli
第 2 步:現在您可以通過輸入以下代碼來創建項目:
ember new <project-name> --lang en
要啟動服務器,請鍵入:
ember serve
示例 1:鍵入以下代碼以生成本示例的路由:
ember generate route test1
應用程序/路線/test1.js
Javascript
import Route from '@ember/routing/route';
import EmberObject from '@ember/object';
import Ember from 'ember';
let List = Ember.ObjectProxy.extend({});
export default class FruitsRoute extends Route {
temp = [
'python',
'javascript',
'java',
'Php',
'Django',
'Angular',
'c++',
'c',
];
list = List.create({ content: this.temp });
item2;
item3;
model() {
return this.list;
}
setupController(controller, model) {
super.setupController(controller, model);
controller.set('item3', this.item3);
controller.set('item2', this.item2);
controller.set('list', this.list);
controller.set('temp', this.temp);
}
}
應用程序/控製器/test1.js
Javascript
import Ember from 'ember';
import { addObject, isAny, isEvery } from '@ember/array';
import EmberObject from '@ember/object';
export default Ember.Controller.extend({
actions: {
print() {
let temp = this.list.content;
alert(temp.join('\n'));
},
find(data) {
alert(this.list.objectAtContent(data));
},
},
});
應用程序/模板/test1.hbs
HTML
{{page-title "Example"}}
<h3>Here is a list of Languages: </h3>
<table>
{{#each @model as |item|}}
<tr>
<td>{{item}}</td>
</tr>
{{/each}}
</table>
<br />
<div>
<label>Enter Index: </label>
{{input value=this.item3}}
</div>
<br />
<div>
<input type="button" id="print-item"
value="Print items At"
{{action "find" this.item3}} />
</div>
<br /><br />
<div>
<input type="button" id="print-item"
value="Print All items" {{action "print" }} />
</div>
{{outlet}}
輸出:
content 屬性輸出2
示例 2:鍵入以下代碼以生成本示例的路由:
ember generate route test2
應用程序/路線/test2.js
Javascript
import Route from '@ember/routing/route';
import { A } from '@ember/array';
import ArrayProxy from '@ember/array/proxy';
export default class List2Route extends Route {
list = ArrayProxy.create({
content: A([
'Oxygen',
'Source Code',
'Infine',
'Tenet',
'SpiderHead',
'The Thing',
'A Quiet Place',
'The Invisible Man',
'Looper',
'Ad Astra',
])
});
model() {
return this.list;
}
setupController(controller, model) {
super.setupController(controller, model);
controller.set('list', this.list);
}
}
應用程序/控製器/test2.js
Javascript
import Controller from '@ember/controller';
import { action } from '@ember/object';
export default class List2Controller extends Controller {
@action
print() {
let temp = this.list.content;
alert(temp.join('\n'));
}
@action
show(data) {
alert(this.list.objectAtContent(data));
}
}
應用程序/模板/test2.hbs
HTML
{{page-title "Example"}}
<h3>Here is a list of eatables: </h3>
<table>
{{#each @model as |item|}}
<tr>
<td>{{item}}</td>
</tr>
{{/each}}
</table>
<br />
<div>
<label>Enter Index: </label>
{{input value=this.item3}}
</div>
<br />
<div>
<input type="button" id="print-item"
value="Item At index" {{action "show" this.item3}} />
</div>
<br /><br />
<div>
<input type="button"
id="print-item" value="Print All items" {{action "print" }} />
</div>
{{outlet}}
輸出:
內容屬性輸出2
