Magento – detect onchange event of country dropdown

cartjavascriptmagento-1.9selectshipping

I am using select2 jQuery plugin to make Magento HTML select nicer. The plugin replaces the actual select with a set of tag which replicate the functionalities of the select. Doing in this way I am missing some default beahviour of Magento select, such as the switch between dropdowns countries and address input field when United States are selected.

Anyone knows where this functionalities are inside Magento js scripts?

Code you are looking for is in js/varien/form.js file. Look for RegionUpdater = Class.create(); line, inside initialize function, you are probably interested in following line:

Event.observe(this.countryEl, 'change', this.update.bind(this));

You can:

1) copy file app\code\core\Mage\Checkout\Block\Cart\Shipping.php in the app\code\local\Mage\Checkout\Block\Cart\Shipping.php

2) define method

protected function _getQuote()
{
    return Mage::getSingleton('checkout/cart')->getQuote();
}

3) in the function getEstimateRates add

$this->_getQuote()->getShippingAddress()
        ->setCountryId($country)
        ->setCity($city)
        ->setPostcode($postcode)
        ->setRegionId($regionId)
        ->setRegion($region)
        ->setCollectShippingRates(true);
$this->_getQuote()->save();

where $country and other variables are you pre-defined values.

4) copy the template app\design\frontend\base\default\template\checkout\cart\shipping.phtml into your custom theme and adjust if if needed.
