Need regex to separate the integer from the array to comma separated

Question

I am looking to have a regex for passing a value in the array to comma separated. Here is the regex I used for the fetching the value.

Regex: id="selectedAgency(.+?)" currently using this regex I am able to find the below value which is matching in id="selectedAgency[1]"

Hence the outcome I receives is as follows:

&selectedAgencies=[14],[12],[10],[9]

However I would like to have the actual output as the below:

&selectedAgencies= 14,12,10,9

Answer 1

not sure if this JavaScript version works for you but here it is. Hopefully the regex and replace part should help.

let str = "&selectedAgencies=[14],[12],[10],[9]";
let result = str.replace(/\[(\d+)\]/g, "$1");   //&selectedAgencies=14,12,10,9

Answer 2

To remove [] use different regex:

 Regex : id="selectedAgency\[(\d+)
