基本布局

常见的布局如下：

• ct-cascadecompared和ct-stickuplayout - 代表是一个cascadecompared组件
  • ct-cascadecompared-indicator - 代表指示器
    • ct-cascadecompared-fixedWrap - 代表固定的部分
      • ct-cascadecompared-item - 代表固定部分的外层 这个元素始终只有一个
        • ct-cascadecompared-cell - 代表固定部分的里层
    • ct-cascadecompared-autoWrap - 代表可以滚动的部分
      • ct-cascadecompared-cell - 代表可滚动的单元格 元素个数同列数相同
  • ct-cascadecompared-master - 代表主体部分
    • ct-cascadecompared-master-inner - 代表主体内的部分
      • ct-stickuplayout-fixed - 固定的列头
      • ct-stickuplayout-inner - 主体部分
        • ct-stickuplayout-item - 一行
          • ct-stickuplayout-item-header - 一行的头
          • ct-stickuplayout-item-content - 一行的内容部分
            • ct-cascadecompared-fixedWrap - 代表固定的部分
              • ct-cascadecompared-item - 代表固定部分的外层 个数等于行数
                • ct-cascadecompared-cell - 代表固定部分的里层
            • ct-cascadecompared-autoWrap - 代表可以滚动的部分外层
              • ct-cascadecompared-autoInner - 代表可滚动的部分内层
                • ct-cascadecompared-item - 代表固定部分的外层 个数等于行数
                  • ct-cascadecompared-cell - 代表固定部分的里层 个数等于列数

初始化

  import CascadeCompared from '@ctmobile/ui-cascadecompared';
  import '@ctmobile/ui-cascadecompared/cascadecompared.less';
  const cascadecompared = CascadeCompared.create(el,config = {columnsWidth = [], rowsHeight = []});

配置项

| 参数 | 类型 | 描述 | | --- | --- | --- | | columnsWidth | array | 列的宽度，例如[50,80,90,....],如果想跳过，可以写成null,undefined,''，跳过的宽度默认为6rem | | rowsHeight | array | 行的高度，例如[50,80,90,....],如果想跳过，可以写成null,undefined,''，跳过的宽度默认为3rem |

方法

scrollToByIndex(index,duration) - 通过索引滚动到某一项

• index-number 要滚动到目标的索引
• duration-number 滚动持续的时间(默认是300毫秒)

scrollToByHeaderEl(headerEl,duration) - 通过dom滚动到某一项

• headerEl-HtmlElement 要滚动到的dom(带有ct-cascadecompared-item-header样式的元素)
• duration-number 滚动持续的时间(默认是300毫秒)

refresh() - 刷新整个StickupLayout

on(type, handler) - 注册事件

• type-string 注册事件的类型,包括[change]
• handler-Function 注册事件的回调函数

事件

| 名称 | 说明 | | --- | --- | | change | 滚动切换时触发 | | scrollEnd | 列滚动完成之后触发 |

  <!--事件例子代码-->
