REgex不适用于空白javascript

Question

I am trying to validate string which can take only alphanumeric values without space.

str.replace(/[^a-zA-Z0-9\u00E0-\u00FC ]+/gi, '')

I used above code but seems still it is taking white space. Did not able to find the right way to fix it.

Answer 1

Remove the space in regexp

  str.replace(/[^a-zA-Z0-9\u00E0-\u00FC]+/gi, '')
