Load Variant Data On Variant Change

---

Description

This first block of code is JS that would call a new page you create which contains the second block of code. The second section looks up the variant product and builds a JSON object to return back to the page.

MivaEvents.SubscribeToEvent("variant_changed", function (product_data) {
    var master_code = product_data.product_code;
    var variant_id = product_data.variant_id;
    var url = "/load-variant-data.html?product_code=" + master_code + "&variant_id=" + variant_id;

    $.get(url, function (data) {
        //Data Bindings
        var obj = JSON.parse(data);

        $("#product_code").html(obj.sku);
        $("#product_name").html(obj.name);
    });
});

<mvt:if expr="NOT ISNULL g.product_code AND NOT ISNULL g.variant_id">

    <mvt:do file="g.Module_Library_DB" name="l.success" value="Product_Load_Code(g.product_code, l.product)" />
