想要在结帐页面添加输入表单以更新运费。到目前为止，我做了以下修改：
1）创建/view/frontend/web/js/custom-checkout-form.js文件并添加以下代码：
define(
[
'ko',
'uiComponent',
'underscore',
'Magento_Checkout/js/model/step-navigator'
],
function (
ko,
Component,
_,
stepNavigator
) {
'use strict';
/**
*
* mystep - is the name of the component's .html template,
* your_module_dir - is the name of the your module directory.
*
*/
return Component.extend({
defaults: {
template: 'your_module_dir/mystep'
},
//add here your logic to display step,
isVisible: ko.observable(true),
/**
*
* @returns {*}
*/
initialize: function () {
this._super();
// register your step
stepNavigator.registerStep(
//step code will be used as step content id in the component template
'step_code',
//step alias
null,
//step title value
'Step Title',
//observable property with logic when display step or hide step
this.isVisible,
_.bind(this.navigate, this),
/**
* sort order value
* 'sort order value' < 10: step displays before shipping step;
* 10 < 'sort order value' < 20 : step displays between shipping and payment step
* 'sort order value' > 20 : step displays after payment step
*/
15
);
return this;
},
/**
* The navigate() method is responsible for navigation between checkout step
* during checkout. You can add custom logic, for example some conditions
* for switching to your custom step
*/
navigate: function () {
},
/**
* @returns void
*/
navigateToNextStep: function () {
stepNavigator.next();
}
});
}
);
2）创建了HTML模板/view/frontend/web/template/custom-checkout-form.html
<div>
<form id="custom-checkout-form" class="form" data-bind="attr: {'data-hasrequired': $t('* Required Fields')}">
<fieldset class="fieldset">
<legend data-bind="i18n: 'Custom Checkout Form'"></legend>
<!-- ko foreach: getRegion('custom-checkout-form-fields') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->
</fieldset>
<button type="reset">
<span data-bind="i18n: 'Reset'"></span>
</button>
<button type="button" data-bind="click: onSubmit" class="action">
<span data-bind="i18n: 'Submit'"></span>
</button>
</form>
</div>
3）删除pub / static / frontend和var / view_preprocessing目录中的所有文件。重新加载页面。
4）在/ view / frontend / layout /
中创建了checkout_index_index.xml布局更新 <?xml version="1.0"?>

但它不适合我。提到了magento的文档http://devdocs.magento.com/guides/v2.0/howdoi/checkout/checkout_form.html。如果我在命名文件时做错了，请纠正我。如果有人可以提供帮助我真的很感激！
