javascript - 从多个 TreeView 中获取所有子节点的 ID(跳过父节点 ID)。如何？

转载作者：行者123 更新时间：2023-11-30 06:32:26

我在用户控件中使用了 TreeView ，它在显示不同数据的单个页面中多次使用。只有三个级别的节点(Parent - Child - Sub Child)

默认情况下，将选择父节点。当用户单击按钮时，是否可以获取在复选框中选中的所有节点(仅子节点和子子节点)的 ID，并验证从页面上的任何 TreeView 中至少选择一个子节点？

注意:必须跳过所有树的父节点的ID。必须从页面中的所有 TreeView 中获取所有子节点和子节点的 ID。所有要连接并用逗号分隔的ID并存储在一个变量中

这可以使用 Jquery 或 js 吗？

最佳答案

这将通过一个节点及其家族递归，获取它遇到的所有 id

function onEvent(ParentNode)
{
    var ids = [];
    GetIds(ParentNode.childNodes,ids);
    console.log(ids.join(","));
}

function GetIds(Family,ids)
{
    for(var i=0,j=Family.length; i<j; i++)
    {
        if(Family[i].id)ids[ids.length] = Family[i].id;
        if(Family[i].childNodes)GetIds(Family[i].childNodes,ids);
    }
}
