Class: DataDialog

WebComponents. DataDialog

This is a custom HtmlElement (Web Component). The tag name is the following:

<cq-data-dialog>

Dialog form that allows users to upload CSV files to be loaded into the chart.

This component comes with a default markup which is used when the component tag contains no other markup when it is added to the DOM. The default markup provided has accessibility features.

Emitters

A custom event will be emitted from the component when it imports data. See CIQ.UI.BaseComponent#emitCustomEvent for details on how to listen for this event. The details of the event contain the following:

property value
emitter this component
cause "useraction"
effect "import"
action "click"
file file data

A custom event will be emitted from the component when it validates data. See CIQ.UI.BaseComponent#emitCustomEvent for details on how to listen for this event. The details of the event contain the following:

emitCustomEvent(params)

Emits a custom event from the webcomponent. The event type of the emitted event is determined by the particular user action taken. Up to two events are emitted when this function is executed. The first is an event with the type of action performed, if there is one. For example, events which are spawned without user action will not emit this first event. The second event will have a type derived from the component name. For example, the cq-study-legend component will emit a "StudyLegend" type event. The payload of the event will contain a detail section specifying the component which emitted the event as well as the effect - which more clearly defines the type of action causing the emittance. The detail section may also include custom fields further categorizing the event and providing additional information. These details are documented within the web component's documentation.

Parameters:
Name Type Description
params object

Name Type Argument Default Description
cause string <optional>

focusNextItem(items [, reverse] [, loop])

Focuses the next item in the tab order.

Locates the first element in items that has a cq-focused attribute. If an element is found, the attribute is removed from all elements in items, and cq-focused is applied to the element that follows (in the tab order) the element that was found.

If no elements are found with the cq-focused attribute, the attribute is applied to the first element in items (last element if reverse is true). If the last element in items (first element if reverse is true) is found to have the cq-focused attribute, focus remains on that element. Unless loop is set to true, then focus is applied to first element.

Parameters:
Name Type Argument Description
items NodeList

A list of elements that are selectable via keyboard navigation.
reverse boolean <optional>

If true, the operation is performed in reverse order; that is, from the last element in items to the first.
loop boolean <optional>

Loops back to the first item if the last element in items is selected.
