It specifies a list of events until consider navigation successful:
- : It considers navigation successful when the whole page, including all dependent resources such as stylesheets images, has been loaded. In certain cases, it might not happen at all.
- : It's fired as soon as the page DOM has been loaded, without waiting for resources finish loading.
networkidle0: It considers navigation successful when page has no networrk activity for half a second. This might never happen if the page is constantly loading multiple resources.
networkidle2: It considers navigation successful when page has no more then 2 network requests for half a second. This is useful if page runs a long polling in the background.
Different arguments work for different pages. When neither of them work, a good solution would be to navigate with
domcontentloadedargument and then simply wait for the needed element to appear on page.
