Question

我在ODATA SAPUI5应用程序中使用嵌套的JSON文件作为模型数据，但我无法访问嵌套数据。

JSON内容

[{
"testcase": {       
    "specification": "SRS PR 28717 – Deposit in Brazilian Reais",
    "execution": {
        "description": "DESC",
        "bca_cn_acct_01": {
            "header": {
                "section": "Field / Section Name",
                "data": "Data to Enter / Value to Select",
                "action": "Activity / Check / Comment"
            },
            "frame": {
                "ID": 1,
                "title": "Create Account: Initial Screen",
                "data": [{
                    "key": "Contract Start",
                    "value": "02/16/2000",
                    "action": ""
                }, {
                    "key": "Contract Manager",
                    "value": "GH_RAMOSCL",
                    "action": ""
                }, {
                    "key": "Product",
                    "value": "BR_IOFTC3",
                    "action": ""
                }, {
                    "key": "Account Holder",
                    "value": "GH_IOF_COR",
                    "action": "Press Enter"
                }]
            }

        }
    },
    "result": "Teste"
}}]

在我的视图文件中，我想以列表的形式访问标记内的数据：

<core:View controllerName="sap.ui.demo.MockServer.controller.App" xmlns:core="sap.ui.core" xmlns:html="http://www.w3.org/1999/xhtml"
xmlns="sap.m">
<!-- <List headerText="{i18n>headerText}" id="list" items="{/Meetups}" noDataText="{i18n>noDataText}">
    <items>
        <ObjectListItem number="{ path: 'EventDate', type: 'sap.ui.model.type.DateTime', formatOptions: { style: 'medium' } }" title="{Title}">
            <attributes>
                <ObjectAttribute text="{Description}"/>
            </attributes>
        </ObjectListItem>
    </items>
</List>
<Button press="onPressAction" text="{i18n>loadFirstItems}"></Button> -->
<List headerText="{i18n>headerText}" id="list" items="{/Meetups}" noDataText="{i18n>noDataText}">
    <items>
        <ObjectListItem number="{ path: 'EventDate', type: 'sap.ui.model.type.DateTime', formatOptions: { style: 'medium' } }"
            title="{testcase/execution/description}">
            <attributes>
                <ObjectAttribute text="{specification}"/>
            </attributes>
        </ObjectListItem>
    </items>
</List>
<Table id="table" items="{/Meetups}">
    <columns>
        <Column width="12em">
            <Text text="Field / Section Name"/>
        </Column>
        <Column minScreenWidth="Tablet" demandPopin="true">
            <Text text="Data to Enter / Value to Select"/>
        </Column>
        <Column minScreenWidth="Tablet" demandPopin="true">
            <Text text="Activity / Check / Comment"/>
        </Column>
    </columns>
    <items>
        <ColumnListItem>
            <cells>
                <ObjectIdentifier title="{testcase/execution/bca_cn_acct_01/frame/data/key}" class="sapMTableContentMargin"/>
                <!-- <Text text="{testcase/execution/bca_cn_acct_01/bca_dte_event_begin_d}" /> -->
                <Text text="{testcase/execution/bca_cn_acct_01/frame/data/value}"/>
            </cells>
        </ColumnListItem>
    </items>
</Table>
<Button press="onPressAction" text="{i18n>loadFirstItems}"></Button>

但是，来自字段键和值的数据不会作为列表检索，尽管它们是JSON数据标记内的数组。

我使用SAPUI5库中的示例教程作为基础：https://sapui5.hana.ondemand.com/#docs/guide/7a78f1b707c248fd9ec53dcb5f10814c.html

有什么想法吗？

我猜你可以绑定整个数组：

{testcase/execution/bca_cn_acct_01/frame/data/}

或者绑定数组的特定元素：

{testcase/execution/bca_cn_acct_01/frame/data/0/key}

您还可以使用格式化程序接收数组并连接数组的所有键检查 Formatter SAPUI5 documentation
