jQuery Common - Object Structures - template
Templates are passed as properties that end with ...Template (in jQuery, Angular, and Vue) or ...Render/...Component (in React).
Each template has access to the following parameters:
data
A data source object or an object with fields specific to a particular template. For information on the contents ofdata, refer to the Template Data section of the template's API reference article.index
A zero-based index of the item in the collection. Available only in collection UI component templates.element
A jQuery element that represents the UI component element being customized. Available only if you use jQuery.
The following code shows how to declare a template and use these parameters. This code declares an itemTemplate for the List UI component:
jQuery
index.js
$(function() {
$("#listContainer").dxList({
items: [
{ itemProperty: "someValue" },
// ...
],
itemTemplate: function (data, index, element) {
return index + " - " + data.itemProperty;
// ===== or using the "element" parameter =====
const $item = $("<div>").text(
index + " - " + data.itemProperty
);
element.append($item);
}
});
});Angular

export default App;Collection UI components also support templates for individual items. Do not specify the UI component's dataSource property if you use individual templates.
