我有一个html文件,其中包含以下代码作为产品列表
<productstore>
<product id='A1'>
<image lbl="Apple" src="assets/apple.png" />
<price>$11.00</price>
<description>Keeps doctor away</description>
<code>ap01</code>
</product>
</productstore>
我想在画布中显示名称和价格的图像(Flex with flash builder 4.5)。我按照链接中给出的示例进行操作 http://blog.flexexamples.com/2008/03/08/creating-a-simple-image-gallery-with-the-flex-tilelist-control/
<mx:XML id="xml" source="prod.xml" />
<mx:XMLListCollection id="xmlListColl" source="{xml.image}" />
<mx:TileList id="tileList" x="492" y="10" width="255" height="316" columnCount="2"
columnWidth="125" dataProvider="{xmlListColl}"
itemRenderer="TileListItemRenderer" rowCount="4" rowHeight="100"
verticalScrollPolicy="on"/>
我正在看的修改是添加dragAccept而不是单击事件,这与示例不同。
这是我的TileListItemRenderer
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"
x="492" y="10" width="255" height="316"
horizontalAlign="center"
verticalAlign="middle">
<mx:Image source="{data.@src}" />
<mx:Label text="{data.@lbl}" />
</mx:VBox>
当我构建并运行列表为空时,不确定我错过了什么。任何帮助,将不胜感激。
我现在修改了代码,尝试实现以下链接并再次卡住: http://blog.flexexamples.com/2008/03/29/dynamically-loading-xml-files-using-the-httpservice-tag/
main.mxml
private function init():void
{
var srcUrl:String = FlexGlobals.topLevelApplication.application.parameters.srcUrl;
if(srcUrl) {
ViewSource.addMenuItem(this, srcUrl);
}
loadProducts('prod.xml');
}
private function loadProducts(src:String):void {
httpService.url = src;
httpService.send();
}
private function httpService_result(evt:ResultEvent):void {
var xmlList:XMLList = XML(evt.result).product.image;
xmlListColl = new XMLListCollection(xmlList);
}
Itemrenderer
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"
x="492" y="10" width="255" height="316" >
<mx:Image source="{data.image}" />
<mx:Label text="{data.name}" />
</mx:Canvas>
XML
<productlist>
<product>
<name>Apple</name>
<image>assets/apple.png</image>
<price>$11.00</price>
<description>Keeps doctor away</description>
<code>ap01</code>
</product>
</productstore>
仍然没有运气......
答案 0 :(得分:0)
{data}变量与xml节点相关。因此,如果要引用's“src”值,则正确的绑定表达式应为:
{data.image.@src}
试试这个并告诉我们结果。
