QUESTION
I have multiple div which has the same class and I want to display only one div per click which belongs to the parent div. I want to hide and show div "post-reply-box".
HTML ...ANSWER
Answered 2021-May-25 at 12:51The issue in your code is because you're using a class selector which retrieves all the .post-reply-box
elements in the DOM, not just the one relevant to the button which was clicked.
To fix this use DOM traversal to relate the elements to each other. In this specific example use closest()
to get the .we-comment
related to the button, then next()
to get the .comnt-reply
container, then find()
.
In addition there some other issues which need to be addressed:
- There's no need to duplicate document.ready handlers. Put all the logic in a single one.
- Use
show()
andhide()
instead ofcss()
to set thedisplay
state of the element. - Use a CSS file instead of inline
style
elements to set style rules. - Attach the event handler to the
a
element, not the childi
, and callpreventDefault()
on the event that's raised. - Add the
type="button"
attribute to theCancel
button so that clicking it does not submit the form.
With all that said, try this:

I am making a spaceship game where you control a spaceship and fire bullets to destroy enemy spaceships. When you click the try again button when you lose, you should be able to both replay and close the game. However, even though I was able to play multiply times, I wasn't able to close the window. I think this has something to do with the if statement that checks if the try again button is clicked. Or maybe it has something to do with something else. How can I fix it so I can close the window at all times?

QUESTION
To preface, I'm currently still learning Swift and just wanted to have a dabble at trying to send data to some kind of backend from within my app. Not sure if important but if so:
- I am using fast comet as a web server with a PHPMyAdmin database in SQL. (struggling to get my head around it so that may be said incorrectly, apologies in advance!)
From what I can gather (please say if I've got this backwards), the executions on the database are written in SQL which I have included in my fetch request for my app (working successfully). The PHP file acts as a bridge to open a connection between the database and my end.
I've tried (semi-successfully) for 3 days to write a POST request in swift that will send the data from my app and insert it into my database. When I say semi-successfully, I mean that when triggering the inert method in my swift code from the app, data DOES get inserted into the database but it is the data on the alternative side of the nil-coalescing operator and not my data. This leads me to believe that all is (just about) okay with my .PHP file and that there is either a problem with my swift code, or that I've not set something up correctly within the database itself?
database with table named "Students" - consists of 5 fields:
id
: INTfirst_name
: TEXTlast_name
: TEXTsubject
: TEXTgrade
: INT
swift - what I'm trying to insert into the database:
id
: IntfirstName
: StringlastName
: Stringsubject
: Stringgrade
: Int

Currently im using the Position of two objects (comets and the ship) to detect if they collide.
...ANSWER
Answered 2021-Mar-11 at 00:26Bevy doesn't have a complete collision system currently. Unless it has been expanded in the few months since the introductory page was created:
PhysicsMany games require collision detection and physics. I'm planning on building a plug-able physics interface with
nphysics
/ncollide
as the first backend.
Fortunately, this simple example is actually provided by bevy::sprite::collide_aabb::collide
which does simple AABB collision detection.
QUESTION
I want to include a checkbox in my PR template which I thought could be achieved by html since Github markdown supports it. It did work fine on VScode but when I pushed it, seems like its broken in Github as it doesn't render the checkboxes. I can think that some people will suggest to use either this:
...ANSWER
Answered 2021-Jan-18 at 22:50You can only user Markdown based checkboxes on GitHub.
If you have an HTML form which contains a checkbox, after the user "checks" the box the form would need to be submitted to a server and then state would need to be updated on the server. GitHub does not have a mechanism to do that.
Additionally, GitHub passes all user provided content through a very rigorous sanitizer which removes many types of content. I expect that they would remove any and all form elements from user provided content as forms would be an easy way for a malicious user to execute attacks of various types.
And then there is the fact that any content included in your issue templates would be displayed to the user within a textarea as raw source. The user would see rather than a rendered checkbox. And then the user would need to edit it to include the
checked
attribute: .
Therefore, the only solution is to use Markdown based checkboxes. The user needs to edit the Markdown by adding an x
inside the brackets to reflect that an item was "checked". Needless to say, that is much easier than adding checked
to raw HTML. And it doesn't require a form to be submitted or a server to receive the submission and save the new state.
