kandi X-RAY | load-more-button Summary
Showcasing your content on the web is more essential than ever but there's so much content and only so much real estate on a web page before the viewer stops scrolling. Web designers and developers have recognized this behavior in website visitors and implement different techniques to display content in the most intuitive way while still providing the volume of content some visitors may require. Your blog may have 1,000 entries but you don't want to show all of them on a single page or it will take an extremely long time to load and cause an information overload that may even increase your bounce rates. In the case of these 1,000 entries developers would likely "lazy load" any entries over a certain integer. In our example, we don't have 1,000 entries so a simple "Load More" and some JavaScript will suffice.

QUESTION
I am trying to scrape the prices of various pharmacies on the site https://www.medizinfuchs.de for a specific drug (e.g., https://www.medizinfuchs.de/preisvergleich/aspirin-complex-beutel-20-st-bayer-vital-gmbh-pzn-4114918.html).
The page works with infinite scrolling that is called via a Load-more-button. Using the network analysis of the developer tools, I see that the page sends a post request to https://www.medizinfuchs.de/ajax_apotheken, if I click this button.
If I copy this post request as a cURL and then convert it with curl2scrapy, I get the following code:

- use a
requests.Session()to store cookies and perform a first call on the urls.get(url). This will get the cookieproduct_historywhich is equal to the product id - use
requests.postto call the API you've spotted in the chrome dev tools, and also specify theidin the form data
The following example iterates a list of products and perform the flow described above :

Answered 2020-Dec-11 at 10:58As mentioned in the comments - your timing out because you're looking for a button that does not exist.
You need to catch the error(s) and skip those failling lines. You can do this with a try and except.
I've put together an example for you. It's hard coded to one url (as I don't have your data sheet) and it's a fixed loop with purpose to keep TRYING to click the "show more" button, even after it's gone.
With this solution be careful of your sync time. EACH TIME the WebDriverWait is called it will wait that full duration if it does not exist. You'll need to exit the expand loop when done (first time you trip the error) and keep your sync time tight - or it will be a slow script
First, add these to your imports:

QUESTION
I have been working on a Wordpress calendar to style the events titles, but ran into a small problem. When the user clicks the load more button the additional events are not styled.
My original code works for the page load but I was thinking of adding another function which executes once the button is pressed after a small delay.
I have tried to modify my original code to work with the button press and delay but I have been unable to get it to working. Is there another way or is something missing in my code below. Again all help is appreciated.

Answered 2020-Sep-24 at 10:58You might be missing the "." on your click target (if mec-load-more-button is a class), Otherwise you are not targetting anything at all

Could somebody please tell me how to make rows of images appear after clicking an achor tag (preferably) or a button. Basically, as you will see, on line 6 there is an tag, which i would like to be able to press so that 3 photos that are inside would appear. In other words : Normally, the 3 photos are not visible, but once someone clicks on "Tapas", all 3 appear. If the anchor tag is clicked again, the 3 photos get hidden again.

I am trying to load comments by paginating them on a blog post via AJAX and the will_paginate gem.
The problem I'm facing is that it's not segmenting the total amount of comments for that post to different pages, it is simply loading duplicate comments of the initial render or "first page of comments".

Answered 2019-Nov-24 at 01:32You are rendering collection: @post.comments (that's not the paginated relation), you should render collection: @comments.
