Struct InputTypeTextShadowTree

struct InputTypeTextShadowTree {
    inner_container: Dom<HTMLDivElement>,
    text_container: Dom<HTMLDivElement>,
    placeholder_container: DomRefCell<Option<Dom<HTMLDivElement>>>,
}

Contains reference to text control inner editor and placeholder container element in the UA shadow tree for text, password, url, tel, and email input. The following is the structure of the shadow tree.

<input type="text">
    #shadow-root
        <div id="inner-container">
            <div id="input-editor"></div>
            <div id="input-placeholder"></div>
        </div>
</input>

Fields

inner_container: Dom<HTMLDivElement>

text_container: Dom<HTMLDivElement>

placeholder_container: DomRefCell<Option<Dom<HTMLDivElement>>>

Implementations

impl InputTypeTextShadowTree

fn init_placeholder_container_if_necessary( &self, host: &HTMLInputElement, can_gc: CanGc, )

Initialize the placeholder container only when it is necessary. This would help the performance of input element with shadow dom that is quite bulky.
