Class s7sdk.search.SearchEffect

The SearchEffect component is an effects component which renders search result regions on top of the page image, it is designed to work with the PageView component only. The SearchEffect uses search results information returned by the search server and processed by Adobe Image Serving to size and position regions in the main view.

The component receives search results data using setSearchResults() API and then processes it on Adobe Image Serving using the req=map command.

Customizing Behavior Using Modifiers

Modifiers change SearchEffect default behavior. They are passed to the component by the ParameterManager instance specified in the constructor.

The following modifiers are supported:

Modifier	Syntax	Description	Default
serverurl	isRootPath	The Adobe Image Serving root path. If no domain is specified, the domain from which the page is served is applied.	/is/image/
direction	auto\|left\|right	Specifies the way pages are displayed in the view. `left` sets a left-to-right display order and `right` reverses the order so that pages are displayed right-to-left. When `auto` is set, the component applies `right` mode when `locale` is set to "ja". Otherwise, `left` is used.	auto

Defining Appearance using CSS

You can define the appearance of the SearchEffect component by using CSS rules. All Adobe Experience Viewers HTML5 SDK components use class selectors for styling. You can style the body of the SearchEffect component by using the .s7searcheffect class selector. The styles associated with this class selector are applied to all instances of the SearchEffect component. Style particular instances by prefixing the class rule with the instance #ID. For example, styling rules for #myComp.s7searcheffect are applied only to the particular SearchEffect instance. For more information on component styling see the Adobe Experience Viewers HTML5 SDK User Guide and the examples in this document.

CSS Class	Attribute Selector	Description
`.s7searcheffect`	(None)	Represents the main element of the `SearchEffect` component.
`.s7region`	(None)	Defines the appearance of individual search result regions. The size and position of the region is managed by the component logic and cannot be customized through CSS.

Class Detail

s7sdk.search.SearchEffect(container, settings, compId)

Example Code
This example demonstrates how to use the "search"-components in a simple viewer. In this example Container,
PageView, SearchManager, SearchButton, SearchPanel, SearchEffect objects are created. Clicking the SearchButton button a search dialog will 
appear and it allow user to input "search text" for searching. 

The code below does the following:

The Adobe Experience Viewers HTML5 SDK is linked to the page and the required s7sdk components are included in the document head.
CSS Styles are defined in the document head to control the appearance of the PageView, SearchPanel and SearchButton components.
The s7sdk.Util.init() method is called to initialize the SDK.
A ParameterManager object is created to handle component modifiers for the viewer.
An initViewer() function is defined. This function initializes a couple of modifiers (hard coded for example purposes),
then creates the component objects required for this simple example. The initViewer() function also adds event listeners
that designate functions to handle relevant component events (which might be dispatched by the components as a result of
user interactions, changes in a component's state, etc.).
A handler function is defined to respond to the component event listener added in the initViewer() function.
An event listener is added to the ParameterManager object that designates the initViewer() function as the handler
to call when the Adobe Experience Viewers HTML5 SDK is loaded and ready.
Finally, the init() method is called on the ParameterManager object to start the viewer.
