having two field with not similar number

[SarvinTorkaman]

Hi, how can I use JSON schema validation to prevent two number input field have the same number entered

You can't do this with JSON Schema out of the box. You'll need extended functionality to do that, like what my data vocabulary provides.

Here's an example similar to what you're trying to do.

Unfortunately, it doesn't seem my vocabulary extension has seen very wide adoption. The only implementation I'm aware of is mine in .Net. You can play with it at https://json-everything.net if you want.

thanks, found a way to solve this issue. used both exclusiveMaximim and exclusiveMinimum to make it uneven

I'm glad you found a solution.

It'd be great if you shared more detail on the problem and solution for any readers who come along later!

      then: {
        required: ['from', 'to'],
        oneOf: [
          {
            properties: {
              to: { exclusiveMinimum: { $data: '1/from' } },
            },
          },
          {
            properties: {
              to: { exclusiveMaximum: { $data: '1/from' } },
            },
          },

      with this method, it will not accept the same value for from and to. but you have to change the error message somewhere else. because the error message you get is not correct
