QUESTION
I'm trying to create a block that allows me to add multiple blocks, where each is a different size in a size estimator.
...ANSWER
Answered 2021-Mar-10 at 18:24Since you've defined size_items
as a StreamBlock, looping over self.size_items
will give you a sequence of StreamChild
objects with block_type
and value
attributes. In this case, block_type
will always be 'size_item'
(since that's the only block type defined within that stream), and value
will be the data for one SizeItem, as a dict. So, you can access the individual fields of that item with a template like:
QUESTION
I am unable to scrape certain data from a YouTube video page in order to create a dataset. I had success scraping other webpages for practice, but can't seem to get it to work for my actual use case.
Specifically I am trying to fetch the username of each YouTube channel in a vector of video_ids. This can be found in the HTML of the video page when inspecting the following element:

QUESTION
I decided to learn flexbox so I found this video (https://www.youtube.com/watch?v=Rf_DjL_dbug&t=3382s) and now I'm stuck. I did everything step by step, and when it comes to styling in CSS ( 50:40 min of video - after adding transform: translateY(-50%); ) all h2 elements going up instead of stay center.
...ANSWER
Answered 2019-Dec-28 at 20:01The person in the video makes a mistake. He wrote down tranform
instead of transform
. His code never applied. I fast forward the entire video to see if he fixes it somewhere, and he doesn't. translate(-50%)
only moves up by 50%. I think the code looks fine without it!
QUESTION
I try to make so that in a range of input at a slide through each 5 values 10 units in the sum were added, everything works, but for some reason after 5 on 6 value is added 10 more, and then everything goes normally.
How it works now: 0(0), 1(0), 2(0), 3(0), 4(0), 5(10), 6(20), 7(20) ... 10 (20), etc.
How should it work: 0(0), 1(0), 2(0), 3(0), 4(0), 5(10), 6(10), 7(10) ... 10 (20), etc.
...ANSWER
Answered 2019-Dec-02 at 19:19The reason your code is working like that is because you give b the value var b = $(this).val()/5;
and then you go with your for from 0 to b.
Than if your value is 6 than b = 6/5
which is actually 1.2
not 1
.
So, in your for
, the i
is first 0
which is lower that 1.2
, then is 1
which is still lower than 1.2
. If you want a simple resolve to your problem just use b=Math.floor($(this).val()/5;)
which 'returns the largest integer less than or equal to a given number' mdn link.
But I have to say your code is pretty hard to read, so you might want to consider working on readability and maybe efficiency too.
QUESTION
I managed to summarize the values from the radio buttons, but I just can’t add the values from range inputs, how can this be implemented?? And yet, since the slider on the two range inputs initially has a value of 1, then in Sum: should already be 2.
...ANSWER
Answered 2019-Dec-01 at 23:51You need to get the value of the range objects and parse them to numbers and add them in your sum:
QUESTION
See jsfiddle
Note that both leading and trailing spaces are stripped from each element fairly consistently, except for the pseudo element (::before.content), which only has its leading space trimmed. Why is this? I would expect the trailing space to be removed as well

QUESTION
I've included the relevant code in this pen: https://codepen.io/whoismikeo/pen/YMvMmR
Basically I'm trying to have an intro section with a button that reveals a second section next to it (or under, on mobile).
...ANSWER
Answered 2019-Apr-21 at 23:28Your JavaScript code is checking if the element with id newFlexItem
has display: none
style property, thus this style property should be added to the HTML element for the checking logic to work on the first click -- it works after the first click because your JS code adds the display: none
style property to the element in the else
block.

QUESTION
The render function in my React app keeps being called which causes problems. I have a function that displays some of the state objects but it fails because it keeps being called. At least that's what I think is happening.
Other errors include uncaught promises and updating the state on an unmounted component. I think these are merely symptoms of the constant rerendering though but I can't be sure. I've pasted all of the relevant code below in the hopes that someone can figure it out and help me.
Code
...ANSWER
Answered 2018-Aug-23 at 08:52Every time you use setState it will render. Well not always, sometimes React will execute several setState actions in one.
I cannot read all the errors, but first one is because page is rendered in the moment when object doesn't exist, so it says cannot read property id of undefined. You can ask before rendering id object exists first. E.g. if(title) title.id etc.
If you need all the steps shown to user, than you have to assume that objects will not exist in certain situations and you always have to check whether object exist before calling the property.
