AddrAF - Address AutoFill

AddrAF is a lightweight plugin to add Japanese postcode lookup to address input forms.

Installation

Simply include the plugin file in your HTML file/project...

<script src="addraf.min.js"></script>

Or from a CDN...

<script src="https://unpkg.com/[email protected]/dist/addraf.min.js"></script>

Then initialise with...

addraf('.selector')

Add the required attributes to the postcode input tag, and optional attributes to the inputs that you want to be filled.
Note that this also works with prefecture select lists, as long as the prefecture option text matches exactly (ie. 愛知県, not just 愛知).

<form class="selector">
    <input type="text" postcode>
    
    <input type="text" prefecture>
    <select prefecture>
        <option value="神奈川県">神奈川県</option>
        <option value="愛知県">愛知県</option>
        <option value="熊本県">熊本県</option>
    </select>
    <input type="text" city>
    <input type="text" address1>
    <input type="text" prefectureKana>
    <input type="text" cityKana>
    <input type="text" address1Kana>
</form>

If a button exists inside the form with the attribute getAddress, data will only be fetched when clicked, not automatically on input.

<form class="selector">
    <input type="text" postcode>
    <button getAddress>Get Address</button>

    <input type="text" prefecture>
    <input type="text" city>
    <input type="text" address1>
</form>
