data-request-validate

Enables inline form validation with error display. When included on a form, validation errors from the server are displayed within the form rather than as alert dialogs.

<form data-request="onSubmit" data-request-validate>
    <div class="alert alert-danger" data-validate-error>
        <!-- Validation messages appear here -->
    </div>

    <div>
        <label>Name</label>
        <input name="name" />
    </div>

    <button type="submit">Submit</button>
</form>

Displaying Error Messages

Use the data-validate-error attribute on a container element to display error messages. The content will be set to the error message and the element made visible.

<div data-validate-error></div>

To display multiple error messages, include an element with the data-message attribute:

<div class="alert alert-danger" data-validate-error>
    <p data-message></p>
</div>

Field-Specific Errors

Use data-validate-for to show validation messages for individual fields:

<input name="email" />
<div data-validate-for="email"></div>

JavaScript API

The browserValidate option enables client-side validation before the request is sent:

jax.request('#myForm', 'onSubmit', {
    browserValidate: true
});
