How to add a selected attribute in option using button using javascript

Asked 2021-Jun-14 at 15:15

I was trying to look for this in the page but can't find.

I was trying to code a 3 buttons where each of this buttons will add a "selected" attribute based on the value or by "value within the id" but my brain cant work it out.

here is my code so far

ANSWER

Answered 2021-Jun-14 at 14:21

You can set the value of the select element directly. to be more efficient, you should run a single function when any of the buttons clicked and make it select either item via an argument.

QUESTION

How to run a scheduled task on a single openshift pod only?

Asked 2021-Jun-13 at 12:03

Story: in my java code i have a few ScheduledFuture's that i need to run everyday on specific time (15:00 for example), the only available thing that i have is database, my current application and openshift with multiple pods. I can't move this code out of my application and must run it from there.

Problem: ScheduledFuture works on every pod, but i need to run it only once a day. I have a few ideas, but i don't know how to implement them.

Idea #1: Set environment variable to specific pod, then i will be able to check if this variable exists (and its value), read it and run schedule task if required. I know that i have a risk of hovered pods, but that's better not to run scheduled task at all than to run it multiple times.

Idea #2: Determine a leader pod somehow, this seems to be a bad idea in my case since it always have "split-brain" problem.

Idea #3 (a bit offtopic): Create my own synchronization algorithm thru database. To be fair, it's the simplest way to me since i'm a programmer and not SRE. I understand that this is not the best one tho.

Idea #4 (a bit offtopic): Just use quartz schedule library. I personally don't really like that and would prefer one of the first two ideas (if i will able to implement them), but at the moment it seems like my only valid choice.

UPD. May be you have some other suggestions or a warning that i shouldn't ever do that?

You can use reduce method of array. First find out the object inside data array and then add that to accumulator array as new entry by preserving the original structure.

QUESTION

Why does str_replace_all is not replacing strings in R?

Asked 2021-Jun-11 at 12:09

I do have a data frame where I need to edit the Diseases names. Each Disease has several rows related to it. For some reason, when I use str_replace_all, the replacement does not happen for two conditions ("Peripheral neuropathies (excluding cranial nerve and carpal tunnel syndromes)", "Venous thromboembolic disease (Excl PE)"). There is no warning or error message in the output, so I can't figure out what is the issue. Does anyone have any ideas?

...

ANSWER

Answered 2021-Jun-11 at 12:09

In regex chaarcters like *, ( have special meaning. str_replace_all by default uses regex replacement. Since you want to match words like "(excluding cranial nerve and carpal tunnel syndromes)" exactly use fixed.

QUESTION

Python - assigning categories based on value range

Asked 2021-Jun-10 at 11:22

Solved

I am trying to figure out why my solution is wrong. Made both, second is correct. I like the first better, because the intervals are more manageable and pleasing for my bad programming brain. And quite frankly, I am kind of lost as to what happens from pH 8 (Neutral) and up (solution 2). Therefore I would like to continue to work in this style for future assignment, rather than solution 2 (correct). However, solution 1 that I prefer is wrong and returns weakly though it should be strongly acidic Why is that and how can this be fixed?

Def: assigning category based on pH (2.3)

pH & category
0–2 Strongly acidic
3–5 Weakly acidic
6–8 Neutral
9–11 Weakly basic
12–14 Strongly basic
Anything else falls in pH out of range

SQL Case statement with Count?

Asked 2021-Jun-10 at 04:49

I have a database that allows for more than one ethnicity per person. Unfortunately, our answers are essentially Yes Hispanic, Not Hispanic, and Unknown, and there are some who do indeed have multiple selections. I need to run a large query that pulls lots of info, one of which is ethnicity, and I want to "convert" those that have multiple selections as Unknown.

person_ethnicity_xref table:

Person_ID Ethnicity_ID 1234567 SLWOWQ 1234567 ZLKJDU

mstr_lists table:

Ethnicity_ID Ethnicity SLWOWQ Hispanic ZLKJDU Not Hispanic

I've been struggling with this as I can't use a For XML Path with two tables, so I'm now trying to use the logic of Case When count(ethnicity_ID)>1 then 'Unknown' Else Ethnicity End
