I want a regex pattern which will allow me any chars, but it will not allow (0-9) numbers?

The [0-9] expression is used to find any character between the brackets. The digits inside the brackets can be any numbers or span of numbers from 0 to 9. Tip: Use the [^0-9] expression to find any character that is NOT a digit.
In this case, [0-9]+ matches one or more digits. A regex may match a portion of the input (i.e., substring) or the entire input. In fact, it could match zero or more substrings of the input (with global modifier). This regex matches any numeric substring (of digits 0 to 9) of the input.
In a regular expression, if you have [a-z] then it matches any lowercase letter. [0-9] matches any digit. So if you have [a-z0-9], then it matches any lowercase letter or digit.
The regex [0-9] matches single-digit numbers 0 to 9. [1-9][0-9] matches double-digit numbers 10 to 99. That's the easy part. Matching the three-digit numbers is a little more complicated, since we need to exclude numbers 256 through 999.
Simply:
/^([^0-9]*)$/ That pattern matches any number of characters that is not 0 through 9.
