Please help me to build a pattern in the text input field like that,
<input name="BusinessOwner" type="text" id="BusinessOwner" pattern="?">
But the rule is that this input field only allow English Small letter and/or Capital letter(include/Exclude space) and no Numeric Digits. So according to the rule,
Adam Smith => valid
adam => valid
AB CD => valid
abcd12 => Invalid
abcd 12 => Invalid
Please help me to build the pattern.
I recommend you to use this pattern:
^([A-Za-z]+[,.]?[ ]?|[A-Za-z]+['-]?)+$
Final:
<input name="BusinessOwner" type="text" id="BusinessOwner" pattern="^([A-Za-z]+[,.]?[ ]?|[A-Za-z]+['-]?)+$">
Hope this would be helpfull.
