Quick Start

To generate the above login form,

1. Create your model:

let forObj = {
    email: '',
    password: '',
    rememberMe: false
}

2. Render the form on the DOM:

import {SvelteForm as Form} from 'boost-web-forms-svelte'

<Form forObject={forObj} />

You will find the complete login form example here.

Setting Options

Use the options prop to set options:

const formConfig = {
    fieldsConfig: {
        email: {
            placeholder: 'email@organization',
            label: 'Your Email',
            required: true
        }
    }
}
<Form forObject={forObj} options={formConfig} />

Two-way Binding

To let the form update the forObject use svelte's bind:

<Form bind:forObject={forObj} />

Now, the forObj gets updated up on every user input.

Form Submission

Use the on:submit event handler to handle form submission

function onLogin(e) {
    // to get the validation result:
    e.detail.validationResult
    
    // to prevent default submission
    e.detail.preventDefault()
}

...

<Form ... on:submit={onLogin}>

Note: This event is only triggered if the form is valid. To prevent auto-validation set autoValidate to false.

<Form ... options={{autoValidate: false}}>

Validation Result

Up on submission, the form will be automatically validated and on:validate will be triggered

function onValidate(validationResult) {
    if (validationResult.detail.hasError)
}

...

<Form ... on:validate={onValidate} />

Consult the boost-web-forms docs for more.

Html Attributes

To set extra html <form> attributes (see) add them in the options prop

let formConfig = {
    id: "form-login", 
    action: "login.php", 
    method: "post", 
    novalidate: true
}

...

<Form options={formConfig} />

Raw HTML field attributes can also be added in the fieldsConfig section.

Refer boost-web-forms docs for more details.
