Javascript 如何将列排序功能添加到表中?
我现在已经尝试了几个小时在react虚拟化表上添加排序功能,但我的大脑无法控制它。。。这是和。很抱歉,我无法创建plnkr,因此我已将链接附加到我的github 当我使用输入文本螺钉提交表单时,会出现此错误,例如:Javascript 如何将列排序功能添加到表中?,javascript,reactjs,react-virtualized,Javascript,Reactjs,React Virtualized,我现在已经尝试了几个小时在react虚拟化表上添加排序功能,但我的大脑无法控制它。。。这是和。很抱歉,我无法创建plnkr,因此我已将链接附加到我的github 当我使用输入文本螺钉提交表单时,会出现此错误,例如: TypeError: list.sortBy is not a function at PartTable._sortList (PartTable.js:136) at new PartTable (PartTable.js:18) 在上的示例中,他们使用上下文(
TypeError: list.sortBy is not a function
at PartTable._sortList (PartTable.js:136)
at new PartTable (PartTable.js:18)
在上的示例中,他们使用上下文(const{list}=this.context;
)而不是道具。也许这就是问题所在
当我记录控制台日志this.props.list
时,我得到了正确的列表(参见两个示例文档)
这里有两个对象来自我的服务器并进入props.list

基于您的代码引用了列表。length
-您接受的列表
道具可能是一个数组?sortBy
方法(假设您从react虚拟化文档中提取了该方法)属于一个。对要使用的JavaScript数组进行排序
附加说明:如果我确认您使用的是数组,那么您粘贴的代码还有一些对List
方法(例如List.get(index)
)的其他引用,您需要将这些方法替换为括号(例如List[index]
)
