问题描述
我正在开发一个带有 TVML 的 Apple TV 应用,它使用 Mustache.js 来填充 UI 元素。
出于某种原因,我的布局没有由 JSON 文件中的数据填充,知道出了什么问题吗?它读取文件是的,因为标题和副标题是可见的,项目的数量也是如此。但是图像和数据没有注入。
小轮播主屏幕已构建,但缺少实际内容。
App.onLaunch = function(options) {
evaluateScripts(options.initialJSDependencies,function(success){
if (success) {
// 2:
resourceLoader = new ResourceLoaderJS(NativeResourceLoader.create());
var initialDoc = loadInitialDocument(resourceLoader);
initialDoc.addEventListener("select",_handleEvent);
navigationDocument.pushDocument(initialDoc);```
} else {
// 3:
var alert = _createalert("Evaluate Scripts Error","Error attempting to evaluate the external JS files.");
navigationDocument.presentModal(alert);
throw ("Playback Example: unable to evaluate scripts.");
}
});
};
问题就在这里:
function loadInitialDocument(resourceLoader) {
var data = resourceLoader.getJSON("homeScreen.json");
data["images"] = resourceLoader
.convertNamesToURLs(data["images"]);
data = resourceLoader
.recursivelyConvertFieldsToURLs(data,"image");
data["sharedImages"] = _sharedImageResources(resourceLoader);
return resourceLoader.getDocument("homeScreen.tvml",data);
}
这是 homeScreen.json
{
"featured": [
{
"template": "video.tvml","data": "trains1.json","image": "TrainsN.lsr","title": "muumuu","subtitle": "jeejee"
},{
"template": "video.tvml","data": "diggers1.json","image": "digs_feat.lsr","title": "juujuu","subtitle": "miumau"
},"data": "ftrucks1.json","image": "ftrucks_feat.lsr","title": "","subtitle": ""
},"subtitle": ""
}
]
}
这是布局(homeScreen.tvml):
<?xml version="1.0" encoding="UTF-8"?>
<document>
<head>
<style>
.imageWithGradient {
tv-tint-color: linear-gradient(top,0.33,transparent,0.66,rgba(0,64,0.7),1.0));
}
.showtextOnHighlight {
tv-text-highlight-style: show-on-highlight;
}
</style>
</head>
<stackTemplate>
<collectionList>
<shelf>
<section>
{{#featured}}
<lockup template="{{template}}" data="{{data}}" presentation="push">
<img src="{{images}}" width="1400" height="800" />
<overlay>
<title>{{title}}</title>
<subtitle>{{subtitle}}</subtitle>
</overlay>
</lockup>
{{/featured}}
</section>
</shelf>
</collectionList>
</stackTemplate>
</document>
