regular expression

Recommended Posts

I need to make a regular expression that will return valid anything not equal to 'select'.  I'm using it to validate a form that has dropdown boxes that are defaulted on 'select'. If they have chosen anything at all, it will not equal 'select', and is therefore valid.

 

I'm not familiar at all with creating expressions, so my last try looked like...

 

  /(?!select)/

You don't need regular expressions for that! Just use

if (fieldValue == 'select')
{
  //error condition
}
else
{
  //value is valid
}

 

However, I would suggest just making the default select value an empty string rather than the string 'select'
