Polymer 1 element for extracting data out of forms. Part of Falcon.io - Build Elements bundle.

<script src="../webcomponentsjs/webcomponents-lite.js"></script> ```html Choice ```

<build-form-schema-extractor> attempts to extract a json schema from a html form using built-in or provided rules to transform the form fields into json schema properties. It will continously update the scheme according to the fields that is currently in the provided form. Example:

    <form id="myForm">
        <input type="text" required name="fullname" placeholder="Full Name">
        <input type="email" name="email" placeholder="Email">
        <input type="number" name="age" placeholder="Age">
        <input type="checkbox" name="choice">Choice
    </form>
    <build-form-schema-extractor
        form="myForm"
        schema="{{ schema }}"
    ></build-form-schema-extractor>

Which would extract in this json scheme

    {
        "type": "object",
        "properties": {
            "fullname": {
                "title": "Full Name",
                "type": "string"
            },
            "email": {
                "title": "Email",
                "type": "string",
                "format": "email"
            },
            "age": {
                "title": "Age",
                "type": "number"
            },
            "choice": {
                "title": "Choice",
