QUESTION
I've a very basic question related to a service. I've this method getAllArticlesFromDb in my service that will fetch data from an API using HTTP's GET call. Here is the method:
article.service.ts
...ANSWER
Answered 2021-May-25 at 19:01You need to use the generic overload on the HttpClient get call. Then the return will match what is specified in your method signature.
QUESTION
I'm looking at a global netcdf file. I want to set all land points that are within the 60-75 deg N band to zero but keep the ocean points in that band as nan. As a second step, I want to keep the values on the land points from 60-75 but set all other land points to zero. Ocean values are NaNs. I just don't get my xarray script to do that - here is what I tried
...ANSWER
Answered 2021-May-01 at 02:22This appeared to be mostly an issue with the logical side, as well as the method used to deal with the NaNs.
The below seems to work for me:
QUESTION
I made a programming language in Java. However, I am having some issues with my parser. The parser only checks the first block or statement or it just checks the first statement, and then it stops checking the rest of what has been inputted. I am not quite sure why it is doing this. It is not meant to happen that way.
A similar thing also happens for while statements in my programming language. While statements are only taking in one statement and then no more, and if one or more is given my language will print out an error (not a Java error but just a print statement that is used as error-handling for my programming language that I have made). I have tried using do { statement(); }while(accept("SEMICOLON")); and while loops but that doesn't seem to work. I also tried something similar to that for the first issue as well but to no avail.
My goal is to get the parser to check more than just one block or statement, and to make the while loops take in more than one statement, like how it should be working according to my language's grammar. Hopefully one of you can help me with these problems.
Tokenizer:
...ANSWER
Answered 2021-Mar-24 at 17:56I've looked over your code and noticed some strange constructs.
Why do you do this (which generates inefficient code) and imo is difficult to read. You want to only print the error if none of the accept calls returns true. Note: the compiler actually generates what I call leap-frog code where it branches around goto bytecode.

I'm trying to send a file using AJAX with the form but the PHP file seems to receive nothing, not only the files but also the form elements. In PHP if i try to get a value from the $_POST i get an Undefined Index.
I've tried:
ANSWER
Answered 2021-Feb-14 at 16:17You should create a new FormData() and append your form values and files to it, and then send it as 'multipart/form-data' in the data (not body) param.
QUESTION
I'm trying to compare two lists to show an image, depending on its result.
The basic idea is to show a list of pictures (with a lowered opacity) and when one element is part of both lists to show the picture without opacity.
when using print() on both lists I get the following results:
ANSWER
Answered 2021-Jan-09 at 16:13You need to change how you're checking for the match.
From your console result, biomes is a list and you're passing it to the .contains method which takes an Object and not a List of Objects.
So this check, s.contains(biomes) wouldn't work. You would have detected it if you assigned a type to biomes in your BiomeElement method.
SOLUTION:
Since you're iterating over s, you can check if the s element at the current index is contained in the biomes list like below:
QUESTION
This is similar to the question asked Drop-down box dependent on the option selected in another drop-down box except I would like to use a C# class to keep a list of the drop down values rather than pure html. The jQuery used in the previous question does not work with what I am trying to do.
I want a user to select a vehicle Make and then have the model List be dependent on what Make was selected
C# Class: DropDowns.cs
...ANSWER
Answered 2020-Dec-01 at 02:28asp-items relies on the server to parse, if the drop-down list is dynamically changed in this way, the client and the server need to maintain real-time interaction. So this method is impossible. You need to use jQuery.
When you see the page, asp-items have been parsed into html. At this time, html can be changed through jQuery.

QUESTION
SQL query with special character ()
The original query (big thanks to GMB) can find any items in address (users table) that have a match in address (address_effect table).
The query works fine if address contains ',' but I can't seem to make it work if there is '()' in the address field.
Here is the sql query that's not working:

Answered 2020-Aug-08 at 22:44Just like you replace the space after each comma with just a comma, use REPLACE() to remove the chars '(' and ')':
QUESTION
I used this ULID example in a project where I not only needed the uniqueness offered by ULID but also its lexicographic sortability.
I discovered, however, that no matter how much I tried, I could not just get the ids generated in a loop sorted.
e.g.
...ANSWER
Answered 2020-Jul-22 at 11:38The ULID has two parts: a time component and a random component.
The time component is the count of milliseconds since 1970.
The random component is updated in two cases:
- when the millisecond changes, a new random value is generated;
- when the millisecond is the same, the random value is incremented by one.
The implementation you show here doesn't do the second step.
Maybe you could include some code like this (just an example):
