QUESTION
I wanted to make a portfolio with card filter effect (to show only relevant cards to a selected category when click a button and to hide other none relevant cards) For that I categorized cards in to 2 categories(classes) as books and articles.
when I click the button "articles" the .show cards are remaining in their original place in the grid (UI) and .hide cards spaces in the UI looks blank rather than re arranging .show cards to fill the gaps.
So need to make show cards to auto arrange without showing empty spaces in (UI).
...ANSWER
Answered 2022-Mar-16 at 19:16The JavaScript part is okay but you've added the target classes to the wrong elements. You should add the classes that you're targeting (.all
, .books
, .articles
) to the .portfolio-item
element instead.
Example: Change

...ANSWER
Answered 2022-Jan-22 at 09:06When you are using the Query#addValueEventListener() method, it means that you are listening for real-time updates (changes). That being said, every change that takes place in the Realtime Database that corresponds to your referencia
query, will always trigger the onDataChange()
method. Since when you are adding data inside the callback to the query you are listening to, your sendToDataBase
gets written again, hence that behavior. This is happening over and over again.
To solve this, simply change the above method call to Query#addListenerForSingleValueEvent(). This means that it will listen for changes only once.
QUESTION
I have been dealing with this particular situation. I have a form in which the user can put some data and save it. He can do that several times creating a record of similar items. The app creates a string with this data and saves it in the localStorage. The user is able to retrieve the data on a page created with an accordion system where he can see it separately just as he typed before. Now I need to get some data from the LocalStorage to show it in a page which is out of the DOM of the app.
This is the js controller code where I want to show the data:
...ANSWER
Answered 2022-Jan-08 at 08:28I think the problem is in the object you call in html2canvas
. I made a codesandbox where I use an accordion and capture the open element to render it on a canvas.
The steps are:
- Get the panel that is open
- Get the panel dimensions to resize the canvas and clean the canvas
- Paint on the canvas
- Download image
I leave below the most important function
QUESTION
I am trying to find an efficient way of doing this. A function to return True if the entry string has a Ph.D/Medical Doctor ( which means prefix of 'Dr.') and the entry has name 'Alex' in it.
I tried the below code which works, but I think there should be a more efficient way of doing it. I will appreciate any thoughts.
...ANSWER
Answered 2021-Dec-27 at 14:44The code looks good. The only feedback I have is regarding the use of 'include?' function for the prefix. Try to use 'start_with?' function instead, so that you don't get True even when the the "Dr" is within the string.
QUESTION
I'm trying to find the best way to group polylines similar to the image below. My issue is that I don't know how to group the lower lines together in a way that the lower lines aren't grouped with the upper lines. This is just a small example so I'd like to stay away from manually identifying the groupings. To reiterate, i'm not concerned with the grouping sizes, i just want to make sure the lower lines and upper lines are not grouped together.
example data:
...ANSWER
Answered 2021-Nov-15 at 20:11Just an idea if you want to cluster the lines into an "upper" and a "lower" group:
- Compute the center of each lines (maybe with
sf::st_centroid()
) - Extract the coordinates of the centers with
sf::st_coordinates()
- build a nx2-matrix containing the center coordinates
- Apply the k-means algorithm (with e.g.,
kmeans
) specifying that you have only to cluster (check the example in the help of the functionkmeans()
) - The
kmeans()
function returns the cluster ID of the lines (1 or 2).

I will show you my php and html code, here my users register in the database, but I have a question for you. How can I ban the use of the same names? That the names of users in the database are not the same or that one user on several accounts does not log in to the same name
...ANSWER
Answered 2021-Jul-28 at 18:01Depends what database you use.
A simpler way would be to just create a unique constraint on the table, this will also enforce it for updates too and remove the need for a trigger. Just do:
Example for MSSQL:
