QUESTION
Need help. Already 4 days nothing happens. Trying to do a SQLite database search. How to make it so that the listview is not displayed immediately, but only when the user enters a search query? That is, the data from the database was not filtered, but matches appeared in the listview when the user enters a request. I am very grateful to everyone in advance!`

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION
I have file txt with format like this
...ANSWER
Answered 2021-Jun-15 at 21:31You add each line to the variable list_Siswa. So for instance the first element of list_Siswa will be ["Nama"," John"], and so data_Siswa[0] equals "Nama" and data_Siswa[1] equals " John". Then data_Siswa[2] throws an error, because there is no such element in the array.
The code isn't smart enough to see Nama: John and assume the following lines are grades that should be associated with John. If you want that, you'll have to do it yourself.

I've been trying to build a small database with Google Sheets for me, my wife, my friend and his partner, to make it quick and easy to search through our recipes from HelloFresh!
I've input all of the recipes, and I am able to query to show recipes we would like based on which meat/vegetable, and what main ingredient (pasta, rice etc).
The next thing I would like to do is have a list generate/filter based on what ingredients we have, in this case cells J6:J13. I would like the list to generate if any criteria is met. For example, if both Chicken Thigh and Beef Mince are selected, it will show all recipes that have chicken OR beef.
Would anyone be able to assist, please?
