Restrictions for input type=text with OnChange

Could someone help me with restrictions for input text?

<input type = text size = 18 name = part_numb value = '' pattern = '([A-NP-Z0-9 -]). {0,50}' id = 'part_numb' required>

In this case, it's not working.

My restrictions are:

  1. The value can't content letter "O", auto-replacement with number "0"

  2. The value can't content small letters, only Capital. (auto-replacement)

  3. The value can't content special symbols except "-" but the value can't start or finish with "-" (auto-removal)

  4. The value can't content free spaces. (auto-removal)

5.  This input is required.

  1. The symbols have to be "A-N", "P-Z", "0-9", "-" 

I thinks that have to use "onChange", but I am not sure.

Please excuse me if this topic is not for here.

Thanks in advance.

Hi all again,

 

May be it's little bit stupid wrote, but it's the way it's almost work. I complied almost all rules. But the rule to not start with '-' I haven't idea how to realize. Please help me.

 

Thanks in advance.

you  just need to convert any value to uppercase, then any 'o' or 'O' converted to lowercase then find index and converted to ''0', if '-' found at end of total length of string length trim it.
