Searchbars represent a text field that can be used to search through a collection. They can be displayed inside of a toolbar or the main content. A searchbar should be used instead of an input to search lists.
A clear button is displayed when a searchbar has a value or upon entering input in the searchbar's text field. Clicking on the clear button will erase the text field and the input will remain focused. By default, the clear button is set to show when focusing the searchbar, but it can be set to always show or never show. The icon inside of the clear button can also be customized to any Ionicon.
A cancel button can be enabled which will clear the input and lose the focus upon click. By default, cancel buttons are set to never show, but they can be set to always show or only show when focusing the searchbar. The cancel button is displayed as text in ios mode, and as an icon in md mode. Both the text and icon can be customized using different properties, with the icon accepting any Ionicon.
Searchbars are styled to look native when placed inside of a toolbar. In iOS, searchbars should be placed in their own toolbar, under a toolbar that contains the page title. In Material Design, searchbars are either persistently displayed in their own toolbar, or expand over a toolbar containing the page title.
A debounce can be set on the searchbar in order to delay triggering the ionChange event. This is useful when querying data, as it can be used to wait to make a request instead of requesting the data each time a character is entered in the input.
Searchbar uses scoped encapsulation, which means it will automatically scope its CSS by appending each of the styles with an additional class at runtime. Overriding scoped selectors in CSS requires a higher specificity selector. Targeting the ion-searchbar for customization will not work, therefore we recommend adding a class and customizing it that way.
By default, tapping the input will cause the keyboard to appear with a magnifying glass icon on the submit button. You can optionally set the inputmode property to "search", which will change the icon from a magnifying glass to a carriage return.
By default, tapping the input will cause the keyboard to appear with the text "return" on a gray submit button. You can optionally set the inputmode property to "search", which will change the text from "return" to "go", and change the button color from gray to blue. Alternatively, you can wrap the ion-searchbar in a form element with an action property. This will cause the keyboard to appear with a blue submit button that says "search".
While not required, this interface can be used in place of the CustomEvent interface for stronger typing with Ionic events emitted from this component.
