[RESOLVED] Need Appropriate Reg Exp & Drop Down Check

[banksworld1986]

I'm having a couple of issues with my form.

1. I need a regular expression that allows only alpha chars for a name field. My regular expression is allowing this (John D##). Also my expression isn't allowing spaces between first and last names like this (John Doe).

function checkIllegalChars(theuser_name, error){

  var name_exp = /[a-zA-Z]+/;
  
  for(var i=0; i < theuser_name.length; i++)
  {
     the_char = theuser_name.charAt(i);
    
    if (!name_exp.test(the_char))
    {
      error.val=2;
      return false;
    }

  }
 return true;  
}

2. My form is suppose to make sure that a city is selected from the drop down menu. Here's my code for that:

 correct=checkSelOpts(sel_opt, error); 
  
  if (!correct)
  {
    error_mes += errors[error.val] + '<br>';
  }
...//else statement is further down...it's not the problem

...
function checkSelOpts(city_opts, error){

 if (city_opts="none")
 {
   error.val=4;
   return false;
 }

return true;
  
}

Now I've checked Firebug and "city_opts" has the value of whatever is selected. So that part is working. But when I hit submit, the form isn't recognizing that a city was indeed selected. It still shows an error message regardless of a city being selected or not. Please help.

comparisons use == or === not =

 if (city_opts=="none")

That's it...Thanks scragar. It worked.
