HTML5 Example

When the Declarative plugin is used, the uri validator will be turned on automatically if the input uses HTML 5 type="url" attribute.

Using with regexp validator example

The following example is a combination usage of the uri and regexp validators. It asks user to enter a valid URL which ends with .jpg, .jpeg, or .png.

Module Example

The following snippet shows how to use the uri validator with JavaScript module:


// You might need to change the importing path
import uri from 'formvalidation/validators/uri';

const res1 = uri().validate({
    value: 'http://foo.com/blah_blah_(wikipedia)',
    options: {
        message: 'The input is not a valid URL',
    },
});
// res1.valid === true

const res2 = uri().validate({
    value: 'http://foo.bar?q=Spaces should be encoded',
    options: {
        allowLocal: true,
        message: 'The input is not a valid URL',
    },
});
// res2.valid === false

const res3 = uri().validate({
    value: 'news://foo.com/blah_blah',
    options: {
        allowEmptyProtocol: true,
        message: 'The input is not a valid URL',
    },
});
// res3.valid === true
