Angular JS-使用其他输入选项更新输入选项 [英] Angular JS - Update input options with other input options

问题描述

我有一个表格，必须在清单中输入一个国家/地区，以便将总计的运输费用加在一起.当我使用ngCart指令时，必须使用 ng-click 将该信息发送到该指令.

I have a form where I have to enter a country from a list in order to add different shipping costs to a total. As I am using ngCart directive, I have to use ng-click in order to send that info to the directive.

问题是我有两个不同的 input选项，它们在表单的不同部分具有相同的字段，并且当我手动更改另一个时，我想更新其中一个的值，以便两个输入中显示的选项始终相同.

The problem is that I have two different input options with the same fields in different parts of the form, and I would like to update the value of one when I manually change the other, so that displayed option is always the same in both inputs.

推荐答案

您可以在select上使用ng-model，并使用ng-options来照顾选项和交付，如下所示:

You can use ng-model on the select and use ng-options to take care of the options and the shipping like this:

<select ng-model="selectedCountry" ng-options="country.name for country in countries" ng-change="changeChipping()">
</select>
