python - make selenium driver wait until elements style attribute has changed -

-

as title suggests need wait dynamically loaded material. material shows when scrolling end of page each time.

currently trying following:

driver.execute_script("window.scrollto(0, document.body.scrollheight);") webdriverwait(driver, 5).until(expected_conditions.presence_of_element_located(     (by.xpath, "//*[@id='inf-loader']/span[1][contains(@style, 'display: inline-block')]")))

is xpath problem here (not familiar)? keeps timing out though display style change when scrolling selenium.

i wait display style change inline-block custom expected condition , use value_of_css_property():

from selenium.webdriver.support import expected_conditions ec  class wait_for_display(object):     def __init__(self, locator):         self.locator = locator      def __call__(self, driver):         try:             element = ec._find_element(driver, self.locator)             return element.value_of_css_property("display") == "inline-block"         except staleelementreferenceexception:             return false

usage:

wait = webdriverwait(driver, 5) wait.until(wait_for_display((by.xpath, "//*[@id='inf-loader']/span[1]")))

you may try tweak poll frequency make check condition more often:

wait = webdriverwait(driver, 5, poll_frequency=0.1)  # default frequency 0.5

-
realizing i'm going take beating this, have several questions "best practices" when constructing laravel route. do laravel routes run "first come first serve" top bottom? if route found, pass control controller (or perform action) , terminate? i have part of application acts url shortner. so, route looks this: route::get('/{id}', array('as' => 'home.text', 'uses' => 'homecontroller@text'), function($id){ //make sure id exists before pushing controller. if (storage::where('shortcode','=', $id)->count() > 0) { // route found } }); how can improved? one, i'm not sure how pass processing on controller conditionally.. sort of controller::make() ..? 3) there better way in laravel check if record exists versus doing mode::where('column','=','value')->count() 4) have legacy urls http://url.com/?...
