Using regular expression to validate latitude and longitude coordinates then display error

Question

How can I use a regular expression to validate the latitude and longitude for these text fields and display an error message?

Answer 1

I used two different regexes for each value.

Latiude Regex:

const latRegex = /^-?([1-8]?[1-9]|[1-9]0)\.{1}\d{1,15}/g;

Longitude Regex:

const lngRegex = /^-?(([-+]?)([\d]{1,3})((\.)(\d+))?)/g;
