My string looks like this street no [12]
I need to extract the 12 alone from the string.
How do I get the substring between two [ ] in javascript or jquery?
find the substring between first matching [] brackets
I noted that your requirements changed in a comment below the previous answer, to fix that issue you can change the regex adding ? so it will capture the least possible matches.
const myString = "street no [12][22]"
const match = myString.match(/\[(.+?)\]/);
const myNumber = match && match[1];
console.log(myNumber);Or, you can just capture digits if that works better for your needs
const myString = "street no [12][22]"
const match = myString.match(/\[(\d+)\]/);
const myNumber = match && match[1];
console.log(myNumber);You can use a regular expression for this:
const myString = "street no [12]"
const match = myString.match(/\[(.+)\]/);
const myNumber = match && match[1];
console.log(myNumber);
