[英]Button to add new row in SAPUI5 table
I am trying to add new lines on a SAPUI5 table by a click of a button. 我试图通过单击按钮在SAPUI5表上添加新行。 I have seen plenty of online tutorials but I have not found exactly my use case.
我已经看过很多在线教程,但是我找不到确切的用例。
The JSON is loaded through a mock server for now (for testing purposes and has this structure: 暂时通过模拟服务器加载JSON(出于测试目的,并且具有以下结构:
{
"Invoices": [
{
"ProductName": "Pineapple",
"Quantity": 21,
"ExtendedPrice": 87.2000,
"ShipperName": "Fun Inc.",
"ShippedDate": "2015-04-01T00:00:00",
"Status": "A"
},
...
]
}
I have a table that is defined like this in the view
: 我在
view
有一个这样定义的表:
<mvc:View controllerName="stepbystep.demo.wt.controller.App" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m" xmlns:core="sap.ui.core"
xmlns:html="http://www.w3.org/1999/xhtml" displayBlock="true">
<Table id="ins" items="{ path : 'invoice>/Invoices', sorter : { path : 'ProductName' } }">
<headerToolbar>
<Toolbar>
<Button icon="sap-icon://add" text="Row" press="addRow"/>
<Button icon="sap-icon://display" text="Row" press="fetchRecords"/>
</Toolbar>
</headerToolbar>
<columns>
<Column hAlign="Right" minScreenWidth="Small" demandPopin="true" width="4em">
<Text text="{i18n>columnQuantity}"/>
</Column>
<Column>
<Text text="{i18n>columnName}"/>
</Column>
<Column minScreenWidth="Small" demandPopin="true">
<Text text="{i18n>columnStatus}"/>
</Column>
<Column minScreenWidth="Tablet" demandPopin="false">
<Text text="{i18n>columnSupplier}"/>
</Column>
<Column hAlign="Right">
<Text text="{i18n>columnPrice}"/>
</Column>
</columns>
<items>
<ColumnListItem type="Navigation" press="onPress">
<cells>
<ObjectNumber number="{invoice>Quantity}" emphasized="false"/>
<ObjectIdentifier title="{invoice>ProductName}"/>
<Text text="{ path: 'invoice>Status', formatter: '.formatter.statusText' }"/>
<Text text="{invoice>ShipperName}"/>
<ObjectNumber
number="{ parts: [{path: 'invoice>ExtendedPrice'}, {path: 'view>/currency'}], type: 'sap.ui.model.type.Currency', formatOptions: { showMeasure: false } }"
unit="{view>/currency}" state="{= ${invoice>ExtendedPrice} > 50 ? 'Error' : 'Success' }"/>
</cells>
</ColumnListItem>
</items>
</Table>
and the controller contains this function (I am only pasting the part that works): 并且控制器包含此功能(我仅粘贴有效的部分):
addRow: function() {
var oList = this.getView().byId("ins");
var oDt = oList.getBinding("items").getModel().oData;
}
However, I am not sure how to proceed. 但是,我不确定如何进行。 I have tried
push()
in the model, but I am getting errors. 我曾在模型中尝试过
push()
,但出现错误。 What I was thinking of doing now is to add an empty row in oDt
and bind it to the table, but I am not sure how to proceed with this, and whether it is the optimal solution. 我现在
oDt
是在oDt
添加一个空行并将其绑定到表,但是我不确定如何进行此操作以及它是否是最佳解决方案。
EDIT: How to Add a New ColumnListItem to a Table was marked as potential duplicate. 编辑: 如何将新的ColumnListItem添加到表中被标记为潜在的重复项。 This question is on the same topic, but the approach of the OP does not seem to match my use case (I am new to SAPUI5, so I might be wrong - in which case, please forgive me).
这个问题是在同一主题上,但是OP的方法似乎与我的用例不符(我是SAPUI5的新手,所以我可能错了-在这种情况下,请原谅我)。
this.getView().getModel('invoice').getProperty('/Invoices').push({/* new invoice data */})
ODataModel : ODataModel :
this.getView().getModel('invoice').create('/Invoices', {/* new invoice data */})
or 要么
this.getView().getModel('invoice').createEntry('/Invoices', {/* new invoice data */})
this.getView().getModel('invoice').submitChanges();
