Jquery Validation: allow only alphabets and spaces

Question

My validation accepts only alphabets. I want allow spaces as well.

$.validator.addMethod("alpha", function(value, element) {
    return this.optional(element) || value == value.match(/^[a-zA-Z]+$/);
});

What change needs to be done here?

Answer 1

Instead of the below regex:

/^[a-zA-Z]+$/

Use this:

/^[a-zA-Z\s]+$/

This will also take the space.

Answer 2

Just leave a space or use \s in your regex:

$.validator.addMethod("alpha", function(value, element) {
    return this.optional(element) || value == value.match(/^[a-zA-Z\s]+$/);
    // --                                    or leave a space here ^^
});

Answer 3

jQuery.validator.addMethod("lettersonlys", function(value, element) {
    return this.optional(element) || /^[a-zA-Z ]*$/.test(value);
}, "Letters only please");

Use pattern: /^[a-zA-Z ]*$/

Answer 4

Your validation is proper. You just need to change regex /^[a-zA-Z ]*$/

$.validator.addMethod("alpha", function(value, element) {
    return this.optional(element) || value == value.match(/^[a-zA-Z ]*$/);
 });

Answer 5

**

I have tried above but space was an issue in above given regex /^[a-zA-Z\s]+$/ and /^[a-zA-Z]+$/. The Below worked for me:

**

  $('.name-val').keypress(function (e) {
    var regex = new RegExp("^[a-zA-Z ]+$");
    var strigChar = String.fromCharCode(!e.charCode ? e.which : e.charCode);
    if (regex.test(strigChar)) {
        return true;
    }
    return false
  });

Answer 6

Please use these pattern for validation.

var pattern = /^[a-zA-Z ]+$/;
if(!pattern.test(name) && name !=''){
    return false;
}
