Elixir Hound等待页面加载 [英] Elixir Hound wait for page to load
问题描述
我正在提交一个登录表单,然后尝试使用elixir / hound捕获HTML。提交后,我运行 page_source
却一无所获。如果我等待一秒钟(页面完成加载),那么我会得到html。
I'm submitting a login form and trying to capture the HTML afterwards using elixir / hound. After submitting I run page_source
and get nothing. If I wait for a second (for the page to finish loading) then I get back the html.
有没有办法让猎犬等到页面完成加载?
Is there a way to make hound wait till the page is finished loading?
我目前正在做::timer.sleep(2000)
作为一种变通方法,希望能更好方法:/
I'm currently doing: :timer.sleep(2000)
as a work around, hoping for a better way :/
推荐答案
这就是我的工作:
创建一个每100毫秒重复检查测试条件的函数,在这种情况下,我正在等待使用
visible_page_text
Create a function that repeatedly checks for a test condition every 100ms, in this case I'm waiting for particular text to appear by using visible_page_text
@tag timeout: 6000
test "My Test" do
assert wait_for(fn -> Regex.match?(~r/Success/, visible_page_text()) end)
end
def wait_for(func) do
:timer.sleep(100)
case func.() do
true -> true
false -> wait_for(func)
end
end
