Regex avoid numeric and special characters and allow space between words

Question

I need validation for Full name text box which should avoid numeric and special characters, but allow space between words. See my JavaScript code here:

function jsPreventNumeric(obj) {
    obj.value = obj.value.replace(/[^a-z]/gmi, '').replace(/\s+/g, '');
}

It's working fine except it's not allowing space between words. I don't have much knowledge to edit that regex. Can anyone help me to adjust this regex to allow space also?

Answer 1

\\s is the escape sequence for whitespace. So your second replace removes all whitepspaces explicitly. /[^az]/ means all characters that are not characters from az. Add \\s so it only removes characters that are not az or whitespace

function jsPreventNumeric(obj){
   obj.value.replace(/[^a-z\s]/gmi,"");
}

Answer 2

I dont see the picture. Try this: ^[\\\\p{L} .'-]+$

Answer 3

解决问题的方法：

obj.value = obj.value.replace(/[^a-z\s]/gmi, "");
