smart-tree
这个库的使用方法跟element-ui里面的el-tree组件类似,所以你可以先了解该组件的使用方法,这里主要介绍额外的功能。
This library is used like el-tree from element-ui, so please read its README before using this library. And in this place we olny introduce the diffrence function.

/*** smart-tree组件的容器必须要有固定尺寸,这是因为它需要计算可视区域。** The container size of smart-tree component should be affirmatoryly, because we must calculate the size* of visiable area.*/
Current Attributes & Functions
ATTRIBUTES:

props
deltaY
defaultExpandLevel
indent
nodeHeight
emptyText
simple
HOOKS:
filterNodeMethod
FUNCTIONS:
filter(value: string): void
updateSize(): void
Usage
There are several attributes and functions:
simple: boolean
simple一般与data属性配合使用,表示data的结构类型。不携带为false,表示data为树型数据结构(element-ui的结构);携带时为true,此时data类型为数组,每个元素根据id和pId属性标识树型关系。
The simple attribute generally used with data, it means that data format is a array.
const data =label: 'item1'id: 1label: 'item2'id: 2pId: 1label: 'item3'id: 3pId: 2
相当于
is equivalent to
const data =label: 'item1'children:label: 'item2'children:label: 'item3'
deltaY: number
deltaY表示鼠标滚轮滚动的幅度,单位为像素。
deltaY means mousewheel delta in vertical bar.
nodeHeight: number
nodeHeight表示每个树节点的高度。
nodeHeight is heigth of tree node.
updateSize (): void
当树的容器大小改变时,可以调用该方法更新显示区域内容。因为容器的大小改变通常是已知的行为,这里并不使用低效的事件监听方式。
You can apply this function when tree container size changed.
