Watch

循环检测，当某事件发生时，执行特定操作

from atx import script_utils as wu

只触发一次效果

btn_login = d(text=u'登陆', className='Button')
once = scu.Once()
once.exists(btn_login) and btn_login.click()

Same as

btn_login = d(text=u'登陆', className='Button')
trigged = False
if not trigged and btn_login.exists:
	trigged = True
	btn_login.click()

存在并点击效果

scu.safe_click(d(text='Update'))

等价于

btn_update = d(text='Update')
if btn_update.exists:
	btn_update.click()

Timeout效果

with scu.while_timeout(50, safe=True):
	pass
	# raise scu.Continue()
	# raise scu.Break()

等价于

safe = True
deadline = time.time() + 50
while time.time() < deadline:
	pass
	# continue
	# break
else:
	if not safe:
		raise RuntimeError("while timeout')
