我正在编程自定义送货方式（商店取货）。
我在本教程中添加了一个附加的下拉菜单：https://zanetabaran.com/how-to-in-magento-2-how-to-add-additional-dropdown-with-options-based-on-selected-shipping-methods-in-the-checkout/
此下拉列表中的值目前是静态的，来自我模块中的js文件->Pastebin
updateDropdownValues: function(method) {
var valuesCollection = [];
if(method['carrier_code'] == 'customshipping'){
valuesCollection = [
{
label: 'Store1',
value: 'Store1'
},
{
label: 'Store2',
value: 'Store2'
},
{
label: 'Store3',
value: 'Store3'
}
];
} else {
valuesCollection = [];
}
self.updateDropdown(valuesCollection);
},
该下拉列表在checkout_index_index.xml-> Pastebin中定义
<item name="shippingAdditional" xsi:type="array">
<item name="component" xsi:type="string">uiComponent</item>
<item name="displayArea" xsi:type="string">shippingAdditional</item>
<item name="children" xsi:type="array">
<item name="shipping-option-wrapper" xsi:type="array">
<!-- Component Magento_Checkout/js/view/additional-shipping-option is used as a wrapper for content -->
<item name="component" xsi:type="string">XXX_CustomShipping/js/view/additional-shipping-option</item>
<item name="provider" xsi:type="string">checkoutProvider</item>
<item name="sortOrder" xsi:type="string">0</item>
<item name="children" xsi:type="array">
<item name="shipping-option" xsi:type="array">
<!-- uiComponent is used as a wrapper for select (its template will render all children as a list) -->
<item name="component" xsi:type="string">uiComponent</item>
<!-- the following display area is used in template -->
<item name="displayArea" xsi:type="string">additionalShippingOptionField</item>
<item name="children" xsi:type="array">
<item name="markt" xsi:type="array">
<item name="component" xsi:type="string">XXX_CustomShipping/js/view/shipping-option-select</item>
<item name="config" xsi:type="array">
<!--customScope is used to group elements within a single form (e.g. they can be validated separately)-->
<item name="customScope" xsi:type="string">shippingOptionSelect</item>
<item name="template" xsi:type="string">ui/form/field</item>
<item name="elementTmpl" xsi:type="string">ui/form/element/select</item>
</item>
<item name="dataScope" xsi:type="string">shippingOptionSelect.select_data</item>
<item name="label" xsi:type="string" translate="true">Please choose a market</item>
<item name="provider" xsi:type="string">checkoutProvider</item>
<item name="visible" xsi:type="boolean">true</item>
<item name="validation" xsi:type="array">
<item name="required-entry" xsi:type="boolean">true</item>
<item name="validate-no-empty" xsi:type="boolean">true</item>
</item>
<item name="sortOrder" xsi:type="number">0</item>
</item>
</item>
</item>
</item>
</item>
</item>
如何将类中的值添加到下拉菜单中？现在，我只能访问quote类中的值。我需要访问自己的帐户（仅供参考：为了显示不同商店的不同可用性）
如果需要更多信息，请随时提出要求。预先谢谢你。
我添加了一个索引控制器<Your_Vendor>/<YourModule>/Controller/Options/index.php，并在<Your_Vendor>/<YourModule>/etc/frontent/routes.xml中声明了它，并且可以使用ajax获取值：
updateDropdownValues: function(method) {
var valuesCollection = [];
if(method['carrier_code'] == 'customshipping'){
$.ajax({
url:"/<your_declared_route>/Optionen/index",
contentType: "application/json",
async:false,
success:function (data) {
valuesCollection = [];
var wert=[];
$.each(data, function (index, thevalue) {
wert=[];
wert["label"]=index;
wert["value"]=thevalue;
valuesCollection.push(wert);
});
},
error: function (xhr, ajaxOptions, thrownError) {
console.log("There has been an error retrieving the values from the database.");
}
});
}
else {
valuesCollection = [];
}
self.updateDropdown(valuesCollection);
},
我的routes.xml：
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd"> <router id="standard"> <route id="yourid" frontName="<your_declared_route>"> <module name="<your_Vendor/Your_Modulname>" /> </route> </router> </config>
