我是Titanium Alloy,MVC框架和Backbone.js的新手,所以我有些头疼。
以前曾问过类似的问题:
Getting ID of clicked TableRow in Titanium Alloy?
Appcelerator Titanium Alloy: How to store data on a ScrollableView to use in click event
但是,尽管我尝试遵循答案,但似乎无法使以下代码正常工作。
基本上,在钛合金中进行数据绑定时,如何将当前模型传递给控制器?
(也是,这是我的第一个问题,因此,如果有任何地方可以改善我的查询,请告诉我,谢谢)。
模型
exports.definition = {
config: {
columns: {
"issueNo": "number",
"date": "string",
"summary": "string",
"cover": "string"
},
adapter: {
type: "sql",
collection_name: "issue"
}
},
extendModel: function(Model) {
_.extend(Model.prototype, {
// extended functions and properties go here
});
return Model;
},
extendCollection: function(Collection) {
_.extend(Collection.prototype, {
// extended functions and properties go here
});
return Collection;
}
};
视图
<Alloy>
<Collection src="issue" />
<Window class="container" onClose="cleanup">
<View id="header">
<Label id="title">Christian</Label>
</View>
<View id="library" class="body" layout="vertical" dataCollection="issue">
<View id="issuesList" model="{alloy_id}" onClick="alertModel">
<ImageView id="cover" image="{cover}"></ImageView>
<Label id="date" text="{date}"></Label>
<Label id="summary" text="{summary}"></Label>
<View class="border"></View>
</View>
</View>
<View id="store" class="body" layout="vertical" visible="false" backgroundColor="yellow">
</View>
<View id="footer">
<TabbedBar id="bottomNav" platform="ios" index="0" onClick="viewSelect">
<Labels>
<Label>Library</Label>
<Label>Store</Label>
</Labels>
</TabbedBar>
</View>
</Window>
</Alloy>
控制者
var Newsstand = require("ti.newsstand");
Newsstand.enableDevMode();
var issues = Alloy.Collections.issue;
issues.fetch();
var issue1 = Alloy.createModel("issue", {
issueNo: 1,
date: "1/1/2014",
summary: "Some text.",
cover: "/issues/cover_1.png"
});
var issue2 = Alloy.createModel("issue", {
issueNo: 2,
date: "1/2/2014",
summary: "Some text.",
cover: "/issues/cover_2.png"
});
var issue3 = Alloy.createModel("issue", {
issueNo: 3,
date: "1/3/2014",
summary: "Some text.",
cover: "/issues/cover_3.png"
});
issues.add(issue1);
issues.add(issue2);
issues.add(issue3);
function viewSelect(tabbedBar) {
var index = tabbedBar.index,
library = $.library,
store = $.store,
bottomNav = $.bottomNav;
if (index === 0) {
library.visible = true;
store.visible = false;
} else {
store.visible = true;
library.visible = false;
}
}
function alertModel(e){
var modelId = e.model,
model = issues.get(modelId),
issueNumber = model.get("issueNo");
alert(issueNumber);
}
function cleanup() {
$.destroy();
}
$.index.open();
最佳答案
根据OP的评论更新了答案:
在您发布的第二个链接上,如果将数据绑定到Views,则表示您需要在视图模板中的所有元素上设置touchEnabled =“ false”,然后在alertModel函数中使用e.source.model。经过测试,对我有用。
var modelId = e.source.model,
model = issues.get(modelId),
issueNumber = model.get("issueNo");
我始终使用ListViews绑定我的数据,并且在使用它们时不需要显式设置touchEnabled。
此外,只有将模型保存到数据库后,才会创建alloy_id。在集合上调用.add()不会保存它,必须在模型上调用.save()才能保存它。
