QUESTION
I am working on a secondary theme for a site of mine (a dark theme). & I can not understand why a specific bit of CSS is not being applied to a particular element, even though it is being applied on another element that is identical.
URL to the site: https://phpstack-726541-2423367.cloudwaysapps.com/ Toggle the switch in the top right hand corner to enable the dark theme. You can see that it only applies it to the 'Header' & not the 'Footer' even though it can be seen that they both use the same classes through Inspect element.
...ANSWER
Answered 2022-Mar-29 at 23:55It's seems that your problem stems from you using querySelector()
Since the output will always be the first element matching the criteria (in your case it seems to be your header) ( https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector )
Try using an id instead for your footer or using querySelectorAll() which will return a list of elements (https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll)
Hope I could help you, keep me updated if you fixed it ! :)

I have another problem today.
ComponentDidMount seems to work fine(it brings data from the server), but when I try to use the data I received, it'd throw TypeError: Cannot read property '0' of null.
What I'm trying to do is to play one of the videos I received from fetching data from the server. I receive my data as an array of nested objects, which is the reason to using [0] to get a certain index of the array elements, but it'd give an error.
Here is part of my function,
...ANSWER
Answered 2021-Jan-24 at 16:49Fetching data from the backend server is async. thats why you need to handle first rendering part as well as null and undefined data set from the backend. for this you can add check for null and undefined values in array.

QUESTION
I have set each section with its own category name and wanted to rearrange its child div elements based on the data
attribute sorted by recent date time published at the top then descending to the bottom.
I'm trying to loop through each of the child elements of its parent but the function reArrangeVideosByRecentUploads()
isn't working. I debugged it and it would stop at this line of code $('.section' + ALPHA_CLASS_NAME + ' .thumb .video-thumbnail').each(function(i) {
and then skip the function entirely. There's no error in the code, so I'm not sure why this is the case.
ANSWER
Answered 2020-Feb-14 at 15:46You're overcomplicating this a little. To sort elements you can use the sort()
method. Provide this method a function which accepts two arguments which are the elements in the iteration to compare to each other. Convert the data-date
values to Date
objects and compare them, returning 1
or -1
depending on which is the most recent.
To keep the logic DRY you can loop over all the section .thumb
containers and sort them individually. Try this:
