QUESTION
I am exceeding my API uses due to the fact that everytime I change tabs on my site it makes a refreshes and makes all the API Calls over again. All the code provided is the component for the tabs, everything works properly just trying to prevent the refresh on tab switches. Is there any way to prevent this?
...ANSWER
Answered 2020-Sep-22 at 06:37You could create another component (e.g. ) that does the API call and renders
passing the teams as props to
. Changing the active tab inside
would then still re-render
but not
and hence not call the API.
QUESTION
I am struggling to figure out how to make the plot reactive. The point of my code is you select a radio button with your team where each team is its own dataset buy they all have the same variables. I understand that I could merge all of them together but I am worried that would slow down the speed of the application itself, also if I were to continue working on this and add specific player stats then I believe my current method is the proper way.
I can print the table easily outside of the shiny app but not in it.
So, overall, the code runs but the plot does not show up and I think I have been looking at it too long and am possibly overlooking a potentially simple error.
The datasets I am using come from NBAsavant.com (link to 76ers team data)

Answered 2020-Jul-30 at 20:39As you didn't provide the data, I used the good old mtcars
as an example.
Issues in the code:
server
/Server
(R is case sensitive)- a reactive dataset has to be called with brackets:
TeamNBA()
scale_fill_continuous(type = "viridis")
uses a variable probably not in the dataset (sounds like from theiris
dataset), so I removed it- at the end of the
renderPlot
, don't useprint
- remove the
box
in theui
function

QUESTION
I started last night so i'm a) sure there is an easy solution and b) not oblivious to the fact that my code is very crappy. So i pulled this Stat table from a website and I already have a function running so that when I type a team name into the website it returns a number. However, what I'm trying to do is have it so that when i type a team name in it won't return a number, but rather it's respective row on the table. The numbers that are currently called in the function are just placeholders for now. As you can see i tried to call a row at the end of the function using an ID I assigned to the Celtics row but what it returns is [object HTMLTableRowElement]. Any help is appreciated, Thanks!!
...ANSWER
Answered 2017-Mar-30 at 00:50Your best bet is
- generate a unique id for each row
- use an expression like document.querySelector(…) to fetch the row by its id
- read the results from the fetched row
You can read the content of a row by iterating through the data cells.
The function document.querySelectorAll()
will return a collection of elements which match a CSS-type pattern. We can then use a for
loop to get the cell contents. I have used textContent
, but if you need to support Legacy Browsers, you might use innerHTML
.
