TextBox Area Code Logic?

Hi:

  If I have a textbox area and have 3 names in it, each name followed by a comma... How can I count the number of names that are in this box?

For example:

a,b,c <==3 names

 

Anyone have any ideas?

Just use the methods available to you on the string object.  Lets say your text area is bound to the string "tBox".

 

public Integer getNumNames() {
  if(tBox != null && tBox.trim() != '') {
    if(tBox.contains(',') {
      return tBox.split(',').size();
    } else {
      return 1;
    } 
  } else {
    return 0;
  }
}
