Patterns

[MimisK13]

Is it possible for a pattern to be made specifically for letters and numbers, without accepting any other characters-symbol??

[SinuheM]

I was trying this
<input type="text" pattern="letter">

And add some lines in default settings (line 38)
letter : ^[A-Za-z ]+$/i,

also near to the line 133
case 'letter' :
regex = this.settings.regex.letter
break;

Thank you very much!!!

You shouldn't need to modify the source to make something like this work.

The documentation explains that the correct way to do this is to add the customised regular expression to the pattern attribute like this:

<input type="text" pattern="^[A-Za-z ]+$"> Cannot include backslash (/) characters as this will be evaluated as a string and not a pattern in line 143 of validator.js

I personally would like to have the option for adding new RegExp to the settings instead of filling the HTML with crafty regular expressions. ;)

I'll PR a change for this and hope @yairEO accepts it. :)

BTW, fantastic job @yairEO, thanks a lot!

Thank you @tiomno :)

You can already bypass the default patterns with a custom settings object.

These are the default settings:

{
    regex : {
        url          : /^(https?:\/\/)?([\w\d\-_]+\.+[A-Za-z]{2,})+\/?/,
        phone        : /^\+?([0-9]|[-|' '])+$/i,
        numeric      : /^[0-9]+$/i,
        alphanumeric : /^[a-zA-Z0-9]+$/i,
        email        : {
            illegalChars : /[\(\)\<\>\,\;\:\\\/\"\[\]]/,
            filter       : /^.+@.+\..{2,6}$/ // exmaple email "steve@s-i.photo"
        }
    },
    alerts  : true,
    classes : {
        item  : 'field',
        alert : 'alert',
        bad   : 'bad'
    }
}

And you can pass it when you instantiate a validator object:

var settings = { 
    regex : { 
        phone : [...]
    } 
};
var validator = new FormValidator({}, settings)

(The first argument is an Object with the texts you wish to override)
