小程序＜scroll-view＞滚动到指定位置/scrollview

注意里面的 scroll-into-view=“{{scrollId}}” 和 id=“scrollView{{index}}” 属性。
当scrollId和scroll-view 组件中元素的id相同时 界面将自动滚动到此位置

<scroll-view scroll-x class="list-label" scroll-into-view="{{scrollId}}" scroll-with-animation="true">
  <view class="label-li {{scrollId=='scrollView'+index?'course-active':''}}" wx:for="{{navList1}}" data-navid="{{index}}" id="scrollView{{index}}" catchtap="navClick1">{{item}}view>
scroll-view>

data:{
// 课程一级标签
    navList1:['全部','一级标签1','一级标签2','一级标签3','一级标签4','一级标签5','一级标签6','一级标签7'],
    navId1:0,
    scrollId:'scrollView3',
},

.list-label{
  margin: 0 30rpx;
  width: 720rpx;
  display: flex;
  margin-bottom: 8rpx;
  overflow-x: scroll;
  white-space: nowrap;

}
