我想知道为什么这不显示我创建的条目。我正在努力寻找使用Marionette的简单教程,所以我采取了在这里找到的愤怒的猫教程(http://davidsulc.com/blog/2012/04/15/a-simple-backbone-marionette-tutorial/)并试图做出类似但更简单的东西,这样我就能理解更好的情况。任何帮助将不胜感激。
这是Javascript,我正在使用Marionette.js
MyApp = new Backbone.Marionette.Application();
MyApp.addRegions({
listBox : "#listBox"
});
Entry = Backbone.Model.extend({
defaults: {
entry : "Blank"
},
});
EntryList = Backbone.Collection.extend({
model: Entry
});
EntryView = Backbone.Marionette.ItemView.extend({
template: "entry-template",
tagName: 'tr',
className: 'entry'
});
EntriesView = Backbone.Marionette.CompositeView.extend({
tagName: "table",
template: "#entries-template",
itemView: EntryView,
appendHtml: function(collectionView, itemView){
collectionView.$("tbody").append(itemView.el);
}
});
MyApp.addInitializer(function(options){
var entriesView = new EntriesView({
collection: options.ents
});
MyApp.listBox.show(entriesView);
});
$(document).ready(function(){
var ents = new EntryList([
new Entry({ entry: 'abc' }),
new Entry({ entry: 'def' }),
new Entry({ entry: 'ghi' })
]);
MyApp.start({entry: ents});
});
这是html:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>Simple Demo</title>
<link rel="stylesheet" href="assets/screen.css">
</head>
<body>
<div id = "listBox">
</div>
<script type="text/template" id="entries-template">
<thead>
<tr class='header'>
<th>Entry</th>
</tr>
</thead>
<tbody>
</tbody>
</script>
<script type="text/template" id="entry-template">
<td><%- entry %></td>
<td><button class="delete">Delete</button></td>
</script>
<script src="js/lib/jquery.js"></script>
<script src="js/lib/underscore.js"></script>
<script src="js/lib/backbone.js"></script>
<script src="js/lib/backbone.marionette.js"></script>
<script src="js/demo.js"></script>
</body>
</html>
答案 0 :(得分:0)
您似乎没有在选项中使用正确的密钥。你应该:
var entriesView = new EntriesView({
collection: options.entry
});
作为旁注,我的“愤怒的猫”教程有点陈旧。要了解使用Marionette视图的基础知识,最好还是阅读这个免费的pdf:http://samples.leanpub.com/marionette-gentle-introduction-sample.pdf(这是我Marionette book的免费样本)
此外,您的模板选择器无效:您需要拥有“#entry-template”,其中包含“entry-template”。
