Macro telegram_button 

macro_rules! telegram_button {
    ($doc:expr, $text:expr $(, class = $class:expr)? $(, $attr:literal = $value:expr)* $(,)?) => { ... };
}

Available on crate feature macros only.

Create a <button> element.

Generates a web_sys::HtmlElement with the provided text, optional CSS class and arbitrary attributes. The macro evaluates to Result<web_sys::HtmlElement, wasm_bindgen::JsValue> so it can be used with the ? operator inside functions returning Result.

Examples

use telegram_webapp_sdk::telegram_button;
use wasm_bindgen::JsValue;

let document = web_sys::window()
    .and_then(|w| w.document())
    .ok_or_else(|| JsValue::from_str("no document"))?;
let button = telegram_button!(document, "Click", class = "primary", "type" = "button")?;
assert_eq!(button.tag_name(), "BUTTON");
