Routing / Toolbar

This example demonstrates how you can observe and handle changes to the browser's location hash.

The location hash can be accessed using q.args['#'].

from h2o_wave import main, app, Q, ui

@app('/demo')async def serve(q: Q):    if not q.client.initialized:['nav'] = ui.toolbar_card(            box='1 1 4 1',            items=[                ui.command(name='#menu/spam', label='Spam'),                ui.command(name='#menu/ham', label='Ham'),                ui.command(name='#menu/eggs', label='Eggs'),                ui.command(name='#about', label='About'),            ],        )['blurb'] = ui.markdown_card(            box='1 2 4 2',            title='Store',            content='Welcome to our store!',        )        q.client.initialized = True    hash = q.args['#']    if hash:        blurb =['blurb']        if hash == 'menu/spam':            blurb.content = "Sorry, we're out of spam!"        elif hash == 'menu/ham':            blurb.content = "Sorry, we're out of ham!"        elif hash == 'menu/eggs':            blurb.content = "Sorry, we're out of eggs!"        elif hash == 'about':            blurb.content = 'Everything here is gluten-free!'    await
