使用方法

跟随tab部分

<farris-scrollspy [scrollspyData]="tabs" [currentSection]="currentTab" [fFollowType]="'tab'" [scrollGroupId]="'scroll'"></farris-scrollspy>

1. scrollspyData 跟随监听滚动的跟随项数组
2. currentSection 当前active项id
3. fFollowType 跟随样式 默认side 可选项tab
4. scrollGroupId 若一个页面中需要使用两次或以上该滚动监听功能，则除了第一次使用，其他每次使用都需要加上该属性，来标记该滚动属于哪个分组

扩展区域

<ng-template scrollspyItem let-scrollItem='scrollItem'> 该扩展区域内放置自定义跟随项样式

主体区域 被监听滚动的内容区域

<div class="scroll-section" fScrollSpyContainer [fOffset]="50" (fScrollChange)="scrollSectionChange($event)" style="height: 400px; overflow-y: auto;"> 主体部分需要有高度，并且有滚动条设置;

1. 需要设置fScrollSpyContainer属性，当页面需要使用两次及以上该功能时，需要传递值，标志滚动属于哪个分组 <div [fScrollSpyContainer]="'scroll'" ...>
2. offset 偏移量，点击及滚动时每个section的偏移量 默认值是0 ;
3. 添加了fScrollSpyContainer属性的标签，默认加上了position:relative样式

主体部分事件

1. fScrollChange 监听滚动区域变化事件，接收参数为当前滚动到区域部分的id

2. 添加了fScrollSpyContainer 属性的标签，默认加上position:relative 样式了

被跟随section部分

<span [fScrollSpy]="'xxx'"></span>

1. fScrollSpy 属性 传递当前section唯一标识的id
2. fScrollGroup 当一个页面中需要使用两次及以上该功能，需要传递值，标志滚动属于哪个分组 <div [fScrollSpy]="'basic'" [fScrollGroup]="'scroll'" ...>

注意事项

当同一个页面需要使用两个及以上该功能，下面地方需要传递分组情况的属性，其中XXX部分值需要保持一致:

<farris-scrollspy [scrollspyData]="tabs" [currentSection]="currentTab" [fFollowType]="'tab'" [scrollGroupId]="'XXX'"></farris-scrollspy>

<div class="scrollspy-content" [fScrollSpyContainer]="'XXX'" [fOffset]="50" (fScrollChange)="scrollTabChange($event)" style="height: 400px; overflow-y: auto;">
    <div class="section" [class.active]="currentTab === 'basic'">
        <span [fScrollSpy]="'basic'" [fScrollGroup]="'XXX'" class="anchor"></span>
    </div>
</div>
