Question

问题：Flex / Flash4客户端（使用FlashBuilder4构建）完全按原样显示从服务器发送的xml - datagrid保留xml的格式。我需要datagrid来解析输入并将数据放在datagrid的正确行和列中。

flow：单击树中的日期，它以xml格式向服务器请求批处理信息。使用CallResponder我然后更新datagrid的dataProvider。

<fx:Script>
    <![CDATA[
        import mx.controls.Alert;
        [Bindable]public var selectedTreeNode:XML;
        public function taskTreeChanged(event:Event):void {
            selectedTreeNode=Tree(event.target).selectedItem as XML;
            var searchHubId:String = selectedTreeNode.@hub;
            var searchDate:String = selectedTreeNode.@lbl;
            if((searchHubId == "") || (searchDate == "")){
                return;
            }
        findShipmentBatches(searchDate,searchHubId);
        }
        protected function findShipmentBatches(searchDate:String, searchHubId:String):void{
            findShipmentBatchesResult.token = actWs.findShipmentBatches(searchDate, searchHubId);
        }
        protected function updateBatchDataGridDP():void{
        task_list_dg.dataProvider = findShipmentBatchesResult.lastResult;
    }

    </batch>

[/代码]

并且xml几乎完全按照上面示例中的datagrid列显示...

感谢您的协助。

我使用简单的xml文字尝试了简化版本的样本，它对我来说很好..

这就是我所拥有的

    <fx:Script>
    <![CDATA[
        import mx.events.FlexEvent;

        protected function onCreationCompleteHandler(event:FlexEvent):void
        {
            task_list_dg.dataProvider = data..batch;
        }

        private var data:XML = //xml example from server
            <batches>
            <batch>
                <rd>2010-04-23 16:31:00.0</rd>
                <mt>SC1REVISION01</mt>
                <ssd>2010-02-18 00:00:00.0</ssd>
                <sss>100000009</sss>
                <fn>Revision 1-DF-Ocean-SC1SUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100218.csv</fn>
                <bn>10041</bn>
            </batch>
            </batches>;



    ]]>
</fx:Script>

<mx:AdvancedDataGrid id="task_list_dg" width="100%" height="95%" paddingLeft="0" paddingTop="0" paddingBottom="0">
    <mx:columns>
        <mx:AdvancedDataGridColumn headerText="Receiving date" dataField="rd"/>
        <mx:AdvancedDataGridColumn headerText="Msg type" dataField="mt"/>

    </mx:columns>

您确定您的数据是以您建议的格式到达吗？（查看FB中的“数据/服务”选项卡）

你是什么意思“显示从服务器发送的xml完全一样 - datagrid保持xml的格式”？它会在网格单元格中转储xml内容吗？

修改：您是否尝试过这样做？

protected function updateBatchDataGridDP():void{
    task_list_dg.dataProvider = findShipmentBatchesResult.lastResult..batch;
}

不得不求助于这种怪物----＆gt;有更好的方法???

        protected function updateBatchDataGridDP():void{
            var batches:XML = new XML(findShipmentBatchesResult.lastResult);
            task_list_dg.dataProvider = batches.batch;
            var task_list_col1:AdvancedDataGridColumn = new AdvancedDataGridColumn();
            task_list_col1.dataField = "@rd";
            task_list_col1.headerText = "Receiving date";
            var task_list_col2:AdvancedDataGridColumn = new AdvancedDataGridColumn();
            task_list_col2.dataField = "@mt";
            task_list_col2.headerText = "Msg type";
            var task_list_col3:AdvancedDataGridColumn = new AdvancedDataGridColumn();
            task_list_col3.dataField = "@ssd";
            task_list_col3.headerText = "SSD";
            var task_list_col4:AdvancedDataGridColumn = new AdvancedDataGridColumn();
            task_list_col4.dataField = "@sss";
            task_list_col4.headerText = "Shipping site";
            task_list_status.text = batches.batch.@sss;
            var task_list_col5:AdvancedDataGridColumn = new AdvancedDataGridColumn();
            task_list_col5.dataField = "@fn";
            task_list_col5.headerText = "File name";
            var task_list_col6:AdvancedDataGridColumn = new AdvancedDataGridColumn();
            task_list_col6.dataField = "@bn";
            task_list_col6.headerText = "Batch number";
            var myColumns:Array = new Array();
            myColumns.push(task_list_col1);
            myColumns.push(task_list_col2);
            myColumns.push(task_list_col3);
            myColumns.push(task_list_col4);
            myColumns.push(task_list_col5);
            myColumns.push(task_list_col6);
            task_list_dg.columns = myColumns;
        }

使用这个xml结构：

<batches>
    <batch rd="2010-04-23 16:31:00.0" mt="SC1REVISION01" ssd="2010-02-18 00:00:00.0" sss="Quanta" fn="Revision 1-DF-Ocean-SC1SUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100218.csv" bn="SHA201004230033" />
    <batch rd="2010-04-23 16:32:14.0" mt="SC1" ssd="2010-02-11 00:00:00.0" sss="Quanta" fn="DF-Ocean-SC1SUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100211.csv" bn="SHA201004230043" />
    <batch rd="2010-04-23 16:35:51.0" mt="PRESHIP" ssd="2010-02-15 00:00:00.0" sss="Quanta" fn="DF-Ocean-PRESHIPSUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100215.csv" bn="SHA201004230045" />
</batches>
