如何隔离嵌套表单？

I'm very new to AngularJS, and new to client side programming.

我是AngularJS的新手，也是客户端编程的新手。

Context:

语境：

I'm implementing a contact form with support for multiple phone numbers and addresses.

我正在实施一个支持多个电话号码和地址的联系表格。

It look like this:

它看起来像这样：

<form name="contactInsertForm" ng-controller="contactInsertController as contactCtrlr" ng-submit="contactInsertForm.$valid && contactCtrlr.save()">
    <input type="text" name="name" />
    <phones-editor></phones-editor>
    <addresses-editor></addresses-editor>
    <input type="submit" />
</form>

phonesEditor and addressesEditor are custom Angular directives which implement support for adding, removing and editing phones and addresses. The controllers and modules look like this:

phonesEditor和addressesEditor是自定义Angular指令，实现了对添加，删除和编辑电话和地址的支持。控制器和模块如下所示：

Addresses:

地址：

(function () {
    var app = angular.module("AddressesEditorModule", []);
    app.directive("addressesEditor", function () {
        return {
            restrict: "E",
            templateUrl: "/addressesEditorTemplate.html",
            controller: function ($scope) {
                this.addresses = [
                    // this will hold addresses.
                ];

                // ...
            }
        }
})();

Phones:

手机：

(function () {
    var app = angular.module("PhonesEditorModule", []);
    app.directive("phonesEditor", function () {
        return {
            restrict: "E",
            templateUrl: "/phonesEditorTemplate.html",
            controller: function ($scope) {
                this.phones = [
                    // this will hold phones.
                ];

                // ...
            }
        }
})();

And the templates:

和模板：

Addresses:

地址：

<!-- list already added addresses -->
<div ng-repeat="address in addressesEditorCtrlr.addresses">
    <p>{{address.address}}</p>
    <p>{{address.city}}</p>
</div>
<form name="addressInsertForm" ng-submit="addressInsertForm.$valid && addressesEditorCtrlr.add()">
    <!-- inputs for each of the address fields -->
    <input type="submit" value="Add" />
</form>

Phones:

手机：

<!-- list already added phones -->
<div ng-repeat="phone in phonesEditorCtrlr.addresses">
    <p>{{phone.number}}</p>
    <p>{{phone.areaCode}}</p>
</div>
<form name="phoneInsertForm" ng-submit="phoneInsertForm.$valid && phonesEditorCtrlr.add()">
    <!-- inputs for each of the phone fields -->
    <input type="submit" value="Add" />
</form>

As you may have noticed, the generated at the browser HTML looks like this:

您可能已经注意到，在浏览器HTML生成的内容如下所示：

<form>
    <input type="text" name="name" />
    <phones-editor>
        <!-- list already added phones -->
        <div ng-repeat="phone in phonesEditorCtrlr.addresses">
            <p>{{phone.number}}</p>
            <p>{{phone.areaCode}}</p>
        </div>
        <form name="phoneInsertForm" ng-submit="phoneInsertForm.$valid && phonesEditorCtrlr.add()">
            <!-- inputs for each of the phone fields -->
            <input type="submit" value="Add" />
        </form>
    </phones-editor>
    <addresses-editor>
        <!-- list already added addresses -->
        <div ng-repeat="address in addressesEditorCtrlr.addresses">
            <p>{{address.address}}</p>
            <p>{{address.city}}</p>
        </div>
        <form name="addressInsertForm" ng-submit="addressInsertForm.$valid && addressesEditorCtrlr.add()">
            <!-- inputs for each of the address fields -->
            <input type="submit" value="Add" />
        </form>
    </addresses-editor>
</form>

The problem:

问题：

I have two form's inside a form. The nested forms work correctly, adding and validating values it should be doing, and refusing to add invalid phones/addresses.

我在表单中有两个表单。嵌套表单可以正常工作，添加和验证它应该执行的值，并拒绝添加无效的电话/地址。

But when I click the submit button at the outer form, it will interpret the inner forms input fields and will raise errors if these fields have invalid values.

但是当我单击外部表单上的提交按钮时，它将解释内部表单输入字段，如果这些字段具有无效值，则会引发错误。

How can I use AngularJS form handling and avoid this situation? Is this possible at all?

This article has exactly what you are looking for.

这篇文章正是您正在寻找的。

The basic gist is that you want to use the ngForm directive inside your form tag.

基本要点是您要在表单标记中使用ngForm指令。

<div ng-form="outerForm">
  <input type="text" ng-model="main.outerFormText"/>
  <div ng-form="innerForm">
    <input type="text" ng-model="main.innerFormText" required/>
    <button type="button" ng-click="main.submit('innerForm')"
      ng-disabled="innerForm.$invalid">Inner Submit</button>
  </div>
  <button type="button" ng-click="main.submit('outerForm')"
    ng-disabled="outerForm.$invalid">Outer Submit</button>
</div>

you would need a directive if you want child form as isolate form. Have a look at answers from this SO question. please have a look at fiddle attached in this answer. I am putting the fiddle link here for you to js-fiddle to see it in action.

如果您希望子表单作为隔离表单，则需要指令。看看这个SO问题的答案。请看看这个答案附带的小提琴。我在这里把小提琴链接给你js-fiddle，看看它在行动。

putting below code just because SO doesnt accept only fiddle links...

把代码放在下面因为SO不接受小提琴链接......

<form name="parent">
    <input type="text" ng-model="outside"/>
    <ng-form name="subform" isolate-form>
        <input type="text" ng-model="inside"/>
    </ng-form>
</form>
