我有一个用XML编写的片段/视图,其中包含一个包含一些列和一个ColumnListItem的简单表:
<m:Table id="CorrectiveActionsTable">
<m:columns>
<m:Column>
<m:Text text="Lfd. Nr"/>
</m:Column>
<m:Column width="30%">
<m:Text text=""/>
</m:Column>
<m:Column>
<m:Text text="gefordert von"/>
</m:Column>
<m:Column>
<m:Text text="Durchführungsverantwortung"/>
</m:Column>
<m:Column>
<m:Text text="Planungstermin"/>
</m:Column>
<m:Column>
<m:Text text="IST-Termin"/>
</m:Column>
</m:columns>
<m:ColumnListItem id="ListItem_00">
<m:Text text="1"/>
<m:TextArea
value="senf"
rows="6"
width="100%"
/>
<m:Input placeholder="bla"/>
<m:Input placeholder="bla2"/>
<m:DatePicker placeholder="bla3"/>
<m:DatePicker placeholder="bla4"/>
</m:ColumnListItem>
</m:Table>
<m:HBox>
<m:Button
text="Add Button"
visible="true"
press="onAddButton"
icon="sap-icon://add"
/>
</m:HBox>
应该使用Button将新的ColumnListItem添加到表中
我想我应该在控制器中编写onAddButton
函数,但我不知道从哪里开始。
现在,我的控制器看起来像这样:
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/m/ColumnListItem",
"sap/m/Text",
"sap/m/TextArea",
"sap/m/Input",
"sap/m/DatePicker"
], function(Controller, ColumnListItem, Text, TextArea, Input, DatePicker) {
"use strict";
return Controller.extend("...", {
onAddButton: function(oEvent) {
var columnListItemNewLine = new ColumnListItem({
cells: [
new Text({
text: "1"
}),
new TextArea({
value: "senf",
rows: "6",
width: "30%"
}),
new Input({
type: "text",
placeholder: "bla"
}),
new Input({
type: "text",
placeholder: "bla2"
}),
new DatePicker({
placeholder: "bla3"
}),
new Datepicker({
placeholder: "bla4"
})
]
});
this._oTable.addItem(columnListItemNewLine);
}
});
});
而且我很确定有一种比我的方法更好的方法。

<items>
聚合。由于聚合绑定,UI5将为您创建一个新的ColumnListItem ,并且您没有破坏MVC模式。以下是一些示例,使用..:
sap.ui.getCore().attachInit(() => sap.ui.require([
"sap/ui/core/mvc/XMLView",
"sap/ui/model/json/JSONModel",
], (XMLView, JSONModel) => XMLView.create({
definition: `<mvc:View
xmlns:mvc="sap.ui.core.mvc"
xmlns="sap.m"
height="100%"
displayBlock="true"
>
<Table sticky="ColumnHeaders" items="{/}">
<headerToolbar>
<OverflowToolbar>
<Title text="My Items ({= %{/}.length})"/>
<ToolbarSpacer/>
<Button
icon="sap-icon://add"
press="onAddItemPress"
/>
</OverflowToolbar>
</headerToolbar>
<columns>
<Column>
<Text text="Column 1" />
</Column>
<Column>
<Text text="Column 2" />
</Column>
</columns>
<ColumnListItem>
<Text text="{col1}" />
<Text text="{col2}" />
</ColumnListItem>
</Table>
</mvc:View>`,
models: new JSONModel([]),
}).then(view => view.placeAt("content"))));
function onAddItemPress(event) {
const model = event.getSource().getModel();
model.setProperty("/", model.getProperty("/").concat({
col1: "newFoo",
col2: "newBar",
}));
}

setProperty
。push
或手动修改模型数据。createEntry
及以后submitChanges
将其发送至后端。答案 1 :(得分:0)
尝试使用以下代码
onAddButton: function(oEvent){
var columnListItemNewLine = new sap.m.ColumnListItem({
cells:[
new sap.m.Text({text: "1"}),
new sap.m.TextArea({value: "senf", rows: "6", width:
"30%"}),
new sap.m.Input({type: "text", placeholder: "bla"}),
new sap.m.Input({type: "text", placeholder: "bla2"}),
new sap.m.DatePicker({placeholder: "bla3"}),
new sap.m.Datepicker({placeholder: "bla4"})
]
});
this._oTable.removeAllItems();
this._oTable.addItem(columnListItemNewLine);
}
