In JS
// DateFormat required from "sap/ui/core/format/DateFormat"
const dt = DateFormat.getDateTimeInstance({ pattern: "dd/MM/yyyy" });
const jsDateObject = dt.parse("2020-08-01T00:00:00"); // returns: Sat Aug 01 2020 00:00:00 <timezone information>
const dayMonthYear = dt.format(jsDateObject) // returns: "01/08/2020"
- If the string contains date and time, parse it via a date time instance.api
.parseapi awaits a string value and converts it into a JS date (e.g. for storing it in a model)..formatapi awaits a JS date and converts it into a string representation (e.g. for displaying it in the UI).
In Two Way data binding (Model-View-ViewModel pattern)
Similar to https://stackoverflow.com/a/63131534/5846045:
<DatePicker value="{
path: '/MyDateTimeString',
type: 'sap.ui.model.type.Date',
formatOptions: {
source: {
pattern: 'yyyy-MM-ddTHH:mm:ss'
}
}
}" />
The framework will then use .format and .parse automatically. I.e. users can pick or enter a date in the UI, and the input will be then parsed and stored as a JS date in the model without writing a single line of JS code.
sap.ui.getCore().attachInit(() => sap.ui.require([
"sap/ui/core/mvc/XMLView",
"sap/ui/model/json/JSONModel", // sample model. Works also with ODataModel.
], (XMLView, MyModel) => XMLView.create({
definition: `<mvc:View xmlns:mvc="sap.ui.core.mvc">
<VBox xmlns="sap.m" class="sapUiTinyMargin">
<DatePicker
width="12rem"
value="{
path: '/MyDateTimeString',
type: 'sap.ui.model.type.Date',
formatOptions: {
source: {
pattern: 'yyyy-MM-ddTHH:mm:ss'
}
}
}"
/>
<ObjectAttribute
title="Model"
text=""{/MyDateTimeString}""
/>
</VBox>
</mvc:View>`,
models: new MyModel({ // e.g. v2.ODataModel
MyDateTimeString: "2020-08-01T00:00:00", // Type="Edm.String"
}),
}).then(control => control.placeAt("content"))));
