我可以在jsonschema形式的lib中为日期输入设置min和max属性吗？

Question

I'm using jsonschema-form lib and I would like to set a min and max date in my input field. As explained in W3C documentation , in HTML5 min and max are attributes of input element.

The JsonSchema I'm using is very simple:

{
  "title": "Date and time widgets",
  "type": "object",
  "properties": {
    "native": {
      "title": "Native",
      "type": "object",
      "properties": {
        "date": {
          "type": "string",
          "format": "date"
        }
      }
    }
  }

The UISchema is:

{
  "alternative": {
    "alt-date": {
      "ui:widget": "alt-date"
    }
  }
}

Can I set min and max attribute for a date input in the jsonschema-form lib? If so, how can do it?

Answer 1

I just bumped into the same challenge and I agree this would be a nice capability. It looks like there is an active issue for adding support of validation: format[Exclusive](Minimum|Maximum) in a future draft of JSON Schema.

Meanwhile I plan to tackle this by by adding a small amount of JavaScript to set the attributes directly on the generated input elements, using either the generated id or a custom class .
