angular.js - angular ui-router 模板内容不显示

Question

找了半天错误，没发现哪里有问题，控制台也没报错，又跑去看官方文档，还是没有发现。
页面始终是空白的，有没有遇到同样情况的指导一下，刚开始学angular。

index.html

app.js

main.html

content.html

想要在main.html添加固定的头部和侧边栏，可是一直显示不出来，页面都是一片空白。

Answer 1

Check whether the address is written incorrectly in the routing settings. If the page and controller are correct, it is usually a problem with ui-router

Answer 2

Why is your main set to abstract?

Answer 3

1. Remove the ui-view class in index.html.
2. In routing, $urlRouterProvider.otherwise('/main');

Answer 4

Write like this:

        .state('book', {
            url: '/book',
            template: '<p ui-view></p>',
            abstract: true,
            resolve: {
                load: ['$ocLazyLoad',
                    function($ocLazyLoad) {
                        return lazyDeferred = $ocLazyLoad.load([{
                            files: [
                                './css/book.css'
                            ]
                        }, {
                            name: '73go.book',
                            files: [htmlBase + 'book/main.js']
                        }]);
                    }
                ]
            }
        })

        .state('book.list', {
            url: '',
            templateUrl: htmlBase + 'book/list.html',
            data: {
                title: '需求及方案'
            }
        })

You don’t need to worry about resolve, it’s a combination with OClazyLoad

abstract: true, if this is set, the interface will not be displayed. You have set up main
