javascript - Regular Expression: Allow letters, numbers, and spaces (with at least one letter not number) -

i'm using regex (/^[a-za-z0-9 _]*[a-za-z0-9][a-za-z0-9 _]*$/) accept letters, numbers, spaces , underscores. want change takes combination of number , character not number.

if understand correctly want allow string begins @ least 1 letter , optionally followed number or underscore or space.

try this: /^(?:[a-za-z]+)(?:[a-za-z0-9 _]*)$/ @ online regex tester.

this should work.

cheers!
