我创建了一个模块，为Magento 2结帐添加了一个新步骤。此步骤具有自定义表单。在提交表格时，我无法弄清楚如何进行下一步。

所以我试图在custom-checkout-form中使用my-step-view.js中的navigateToNextStep（），但我不确定如何引用它。我还研究了为getRegion提供参数。我刚刚开始使用Magento 2和KnockoutJS，所以如果这是一个愚蠢的问题，我很抱歉。我按照Magento 2 Dev Docs创建了新步骤和自定义表单。在此先感谢：）

答案 0 :(得分：2)
我需要在custom-checkout-form.js中添加stepNavigator作为参数。
/*global define*/
define([
'Magento_Ui/js/form/form',
'Magento_Checkout/js/model/step-navigator'
], function(Component, stepNavigator) {
'use strict';
return Component.extend({
initialize: function () {
this._super();
// component initialization logic
return this;
},
/**
* Form submit handler
*
* This method can have any name.
*/
onSubmit: function() {
// trigger form validation
this.source.set('params.invalid', false);
this.source.trigger('customCheckoutForm.data.validate');
// verify that form data is valid
if (!this.source.get('params.invalid')) {
// data is retrieved from data provider by value of the customScope property
var formData = this.source.get('customCheckoutForm');
// do something with form data
console.dir(formData);
stepNavigator.next();
}
}
});
});
