我在 ODATA SAPUI5 应用程序中使用嵌套 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签内的数据：
<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，字段键和值的数据不会作为列表检索，尽管它们是 JSON 数据标签内的数组。
我使用 SAPUI5 库中的示例教程作为基础：https ://sapui5.hana.ondemand.com/#docs/guide/7a78f1b707c248fd9ec53dcb5f10814c.html
