【中文标题】无法从状态“家”解决“___” - 角度 ui-router 问题【英文标题】：Could not resolve '___' from state 'home' - angular ui-router issue 【发布时间】：2015-05-12 14:52:40 【问题描述】：

我是 Angular 新手并遵循本教程：

https://scotch.io/tutorials/angularjs-multi-step-form-using-ui-router

但我将此模块注入到另一个现有模块中。

但是，我不断收到“无法解决状态”错误 - 我不知道为什么，但怀疑它要么是路由问题而且我很笨，要么是嵌套视图问题（注意嵌套 ui-在 index.html 中查看，然后在 home.html 中再次查看）。

使用 angular ui 版本 0.2.13 角度版本 1.3.14

请帮忙！！

下面是相关代码：

结构：

home.html

                 <div id="form-container">

                    <div class="page-header text-center">
                        <h2>Let's Be Friends</h2>

                        <!-- the links to our nested states using relative paths -->
                        <!-- add the active class if the state matches our ui-sref -->
                        <div id="status-buttons" class="text-center">
                            <a ui-sref-active="active" ui-sref=".profile"><span>1</span> Profile</a>
                            <a ui-sref-active="active" ui-sref=".interests"><span>2</span> Interests</a>
                            <a ui-sref-active="active" ui-sref=".payment"><span>3</span> Payment</a>
                        </div>
                    </div>

                    <!-- use ng-submit to catch the form submission and use our Angular function -->
                    <form id="signup-form" ng-submit="processForm()">

                        <!-- our nested state views will be injected here -->
                        <div id="form-views" ui-view></div>
                    </form>

                </div>

                <!-- show our formData as it is being typed -->
                <pre>
                     formData

【问题讨论】：

你弄错了州名。对于子视图，请相应地设置州名。 plnkr.co/edit/08XPp8?p=preview 【参考方案1】：

您的代码没有完全按照教程进行。请注意，要使子状态发挥作用，它们必须引用其父状态。
