Password strength? Say being able to specify for example must contain letter number uppercase lower case symbol and so on.

[PascaleBeier]

I can surely add uppercase, lowercase and special char Rules which one could combine! Am 10.03.2018 00:59 schrieb "Patrick" <notifications@github.com>:

Have a look at src/rules and tests, should be easy to implement If you wanna give it a shot Am 10.03.2018 01:28 schrieb "Pascale Beier" <mail@pascalebeier.de>:

It would be nice to have a startsWithOr(1,2) which will allow you to specify that it needs to start with either 1 or 2..

[PascaleBeier]

@Niladem cool idea!

I could do that for any rule with n additional arguments. Definitely doing that.

I need a 'divisible by' rule.
Example: Input need to be divisible my 0.5: so 1.5 is valid, 1.6 is not.

I think this code should do the trick:
divisible: (input, divisible) => {
return isInteger(Number(input.value/divisible));
},

[StefCoene]

And I also need an other rule. I need to match a field so the date is in the format YYYY-MM-DD.
Matching the general format is enough. So MM > 13 is allowed.
Maybe it can be a general regexp so it's usable in other situations?

Hey Stef,

Worthy suggestions! Feel free to send a PR. I'm short on freetime atm.

I'm working on a new bootstrap 4 project and we need to do some input validation. Your code seems the only form validation code that works with bootstrap 4.
But we are missing some rules. It's not really urgent because the project is still in development state. So take your time.

@StefCoene Check out v2.1.0

[niladam]

Hey @PascaleBeier how about this ? (please keep in mind that my programming skills aren't how i'd like them to be)

  startsWithOr: (input, string, string2) => {
    /**
     * @since 2.1.1
     * @param string string: String the input value should start with
     * @param string2 string: Second string the input value should start with
     * @example 1,2
     * @error Your input should contain either 1 or 2.
     * @description Require the input value to start with a given string
     * or a different string.
     */
    // Check first string
    let istrue = false;
    if ( startsWith(input.value, string) ) {
        istrue = true
    }
    if ( startsWith(input.value, string2) ) {
        istrue = true
    }
    return istrue;
},

[niladam]

I think it would be safe to verify if there are 2 strings in the function, and if not, basically just run startsWith on it. If there are 2 strings, than they'd both need to be verified..

[PascaleBeier]

Hey @niladam,

The reason I didnt implement it yet is that I want to find a solution to dynamically add these ...Or-Rules. Will look at that again these days.

Your Code is nice! You could also use the or Operator :)

[StefCoene]

Cool, thanks for the quick response!

For the divisible, I also need to check if something is divisible by 0.2.
For instance, 3.1 % 0.2: false, 4.2 % 0.2: true
I think this should do the trick:

if ( number < 1 ) {
  return Number(input.value / number) % 1 === 0;
} else { 
  return Number(input.value) % number === 0;
}

[PascaleBeier]

@StefCoene TIL that % is no modulo operator but a remainder operator per definition in JavaScript 🛩

Should have tested that more thorough!

Fixed in d58f8e0 - Which did not ultimately fix it:

I ended up using arbitrary-precision decimal arithmetic via https://github.com/MikeMcl/big.js. Might come in handy in the future. Shipped it with 2.1.2. I cleaned our comments, don't feel offended!
