QUESTION
So, I've implemented this custom dropdown list in Vue JS (2.x) and pretty much have what I need, except once the list is open, I would like for a click outside the component (anywhere on the parent page or component) to close the list. I tried catching the blur
event of the root div
of my component, but it understandably didn't work, because div
s don't get focus and hence cannot be blurred. So at this moment, the solution seems to be - to be able to listen for a click event outside the component. Is that possible? Can a child listen for events on its parent in Vue? If or even if not, what is the best and/or the easiest way to achieve this behavior?
Here's my code in a CodeSandbox, and I am also reproducing it below for convenience - https://codesandbox.io/s/romantic-night-ot7i8
Dropdown.vue
...ANSWER
Answered 2021-May-02 at 05:52ok... this is by far not the best solution but it is a working solution. i used all my MacGyver powers and found a way.
please check this CodeSandbox
all i did was to use your listOpen
and added a eventListner. i figured out that your custom dropdown has no build in @blur
because its not a input ofc.
so i added a event for it inside the mounted
hook.
the key is i also added a setTimeout
on 100ms because otherwise you where not able to select any item inside your dropdown, the dropdown would close with blur
faster then you are able to select anything.

Answered 2021-Apr-09 at 06:26Two options. First is you could add to the SQL “WHERE parent=1”, what will get you all items where the parent = 1.
Section option would be to put an if statement in to say to only display if the parent = 1.
QUESTION
I'm using Moment JS, and have just recently outputted the timezones listed using this.$moment.tz.names()
in my Nuxt JS project. However, the timezones that my server has inside of the timezone_identifiers_list
function in PHP seems to be about 100 or so less, and weirdly, it seems that some important ones are either missing from PHP, or not meant to be in Moment, such as:
US/Central
Why would PHP not contain these missing timezones from Moment?
I'll attach a screenshot of the ones that appear to be outputted from Moment that aren't in PHP, wondering how I can get these timezones into that PHP list?
I've outputted the list of timezones from PHP into a string, because I'm going to have to compare the moment ones then and set a default if my timezone guess logic picks one that doesn't exist since I have a Laravel validation rule for timezone.
...ANSWER
Answered 2021-Apr-04 at 14:09There's a thing called tz, zoneinfo, or the Olson database. It's maintained by the Internet Assigned Numbers Authority
It names zones in Continent/City
or sometimes Continent/State/City
format, like Asia/Kolkata
or America/Indiana/Knox
. Each named zone contains rules for converting to and from UTC time to local time, including the correct handling of summer time.
The database contains the temporopolitical history of time zone and summer time changeovers for the city (and surrounding regions). So, if the government of, say, Knox Indiana USA, changes the summer time rules next year, their entry gets updated in a maintenance release of the database.
If Spain decides to repudiate its Franco-era decision to use the same time zone as 'Europe/Berlin', and move to the same zone as 'Europe/Lisbon', the updated zoneinfo data for 'Europe/Madrid' will reflect that change on its effective date. Updates to UNIX-based operating systems like Linux and MacOS include the most recent zoneinfo data.
php uses zoneinfo. So does MySql. moment.js adds synonyms to it. If somebody in Knox sets their time zone to moment's synonym 'US/Central' and the city council the changes the rules, they won't follow the change.
So, please consider using php's list in your application, because it's proven so far to be future-proof.

The enhance_image()
function should write the edited photo to a folder. But it doesn't do anything. It doesn't even return an error in the command line so I'm having a hard time finding where I went wrong.
ANSWER
Answered 2021-Feb-22 at 08:33The issue is that you have used imagein
, an instance of ImageTk.PhotoImage()
, in os.path.join(path, imagein)
.
Actually you don't need imagein
at all, simply use root.fileBrowse
is enough. Also you can use PIL.Image
to read and write image instead of using cv2
module.
Below is a modified enchance_image()

QUESTION
I'm having problems showing images that the user had input using cv2.imread. Tried using cv2.imshow and canvas.create_image.
...ANSWER
Answered 2021-Feb-11 at 19:06Your program is currently not specifying any path as you have image = cv2.imread("/")
.
askopenfilenames()
returns a tuple of files, so if you wish to have multiple files then you would have to create a loop and pass one path at a time, but if you need a singe file to be selected use askopenfilename()
, this returns a string of the file path selected.

I am trying to learn how to work with APIs. I am using the common openweathermap.org API. The object given by the API is:
Here is a picture of the object that is returned: 1
Here is my js code for reference:
...ANSWER
Answered 2020-Dec-15 at 14:21You'll not notice that your API probably returns all of the data in JSON, meaning it's in object form. Data in objects can be accessed with objectName.key that will return the value of that key for example object dog = { tail: true } will return true on dog.tail.
Here is a great article to learn more about objects.
