QUESTION
I am building a sudoku game in AngularJS. What I want to achieve is to catch ng-keypress even if I click outside of the div on the page. Take a look at http://sudoku.com/ for example if you select a cell and then click wherever you want on the page and after that, if you click on any number still it is going to change that number in the cell. How can I achieve that?
Please take a look at the HTML code below:

Answered 2020-Apr-14 at 03:04So the issue is because ng-keydown
is on the tag so the function will only be called when it's the currently focused element, but it sounds like you want to respond to the key down event from anywhere on the page.
You can do this by using ng-keydown
on the body tag instead of the , then make the function broadcast an event that can be listened to from the sudoku component to run the insertNum logic. Like so:

So, I have a sudoku generator, when accessing through API, it generates a Sudoku board (JSON array) which then with AngularJS and ng-repeat in a tabled I am displaying the Sudoku board on the page.
So far, this is what I have. What I want to achieve is to highlight all the elements that are within the box plus the row and the column. Now the row and the column is highlighted but how can I also highlight the elements that are marked with yellow in the picture below because those elements belong to the box:
Here is my HTML code:

QUESTION
How can I make an array of tuples where the second element of the tuple is inferred from the first?
Here's the typescript playground of the below code.
My situationI'm using Puppeteer to open various Sudoku sites, read in the game, solve it, and move onto the next site.
Each site is represented by a Puppet
where TDiff
is a set of strings representing a site-specific difficulty name (if there is one). I have a function called runPuppet
which takes in a Puppet
and some options, one of which is difficulty, and then performs the above algorithm.
(Sorry for the long code snippets. I tried to keep them short as possible.)

Answered 2019-Jul-21 at 19:22I don't know if I have time to fully explain this, but as a sketch.. the basic idea is to make a generic helper function whose generic type parameter is intended to be a tuple corresponding to the first parameter of each of your pairs, and then map this tuple type to the actual pairs you are passing in. The compiler should be able to use inference from mapped types to infer the type parameter from the passed-in array, or warn you if you do something that can't be inferred. There are all sorts of caveats about hinting the compiler to interpret a parameter like ["a", 1]
as [string, number]
and not Array
, how to get the proper inference, etc, but that's the basic idea. Here's one way to do it:
