Class s7sdk.common.SearchButton


Extends s7sdk.common.Button, s7sdk.common.TwoStateButton.

The SearchButton is a two state button that is used to show and hide search UI. The selected state is automatically changed when user clicks/taps on the button. Alternatively, the state can be changed through setSelected() API.

The component can be added to the ControlBar and grouped with other UI components.

Currently this component does not support any modifiers.

Defining Appearance using CSS

You can define the appearance of the SearchButton component using CSS rules. All HTML5 Viewer SDK components use class selectors for styling. You can style the body of the SearchButton component by using the .s7searchbutton class selector. The styles that are associated with this class selector are applied to all instances of the SearchButton component. You can style particular instances by prefixing the class rule with the instance #id. For example, styling rules for #myComp.s7searchbutton are applied only to the particular SearchButton instance.

CSS ClassAttribute SelectorDescription
.s7searchbuttonselected=[true|false] state=[up|over|down|disabled]Define appearance of SearchButton for each state, independently for selected and unselected case.
.s7tooltip(None)A global class selector that defines appearance for the tooltips. To disable tooltips set the display style to none.

Localizable Symbols

SearchButton also has text symbols that you can localize either in a preset or in the viewer page though the mechanisms provided by the ParameterManager. For more information on localization consult the ParameterManager API documentation and HTML5 Viewers SDK User Guide.

SymbolDescription
SearchButton.TOOLTIP_SELECTEDTooltip for selected button state
SearchButton.TOOLTIP_UNSELECTEDTooltip for unselected button state

s7sdk.common.SearchButton(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:

    

  1. The Scene7 HTML5 SDK is linked to the page and the required s7sdk components are included in the document head.
    2. 

  2. CSS Styles are defined in the document head to control the appearance of the PageView, SearchPanel and SearchButton components.
    3. 

  3. The s7sdk.Util.init() method is called to initialize the SDK.
    4. 

  4. A ParameterManager object is created to handle component modifiers for the viewer.
    5. 

  5. 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.).
    6. 

  6. A handler function is defined to respond to the component event listener added in the initViewer() function.
    7. 

  7. An event listener is added to the ParameterManager object that designates the initViewer() function as the handler
to call when the Scene7 SDK is loaded and ready.
    8. 

  8. Finally, the init() method is called on the ParameterManager object to start the viewer.
    9.
