Question

我在用户控件中使用了树视图，该控件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（父 - 子 - 子子）

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ID（仅限子节点和子子节点）并验证是否从页面上的任何树视图中选择至少一个子节点？

注意：必须跳过所有树的父节点的ID。必须从页面中的所有树视图获取所有子节点和子子节点的ID。所有要连接的ID，用逗号分隔并存储在变量

中

这可以使用Jquery或js吗？

Answer 1

这将通过一个节点及其家族进行递归，抓住它遇到的所有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);
    }
}

从多个树视图中获取所有子节点的ID（跳过父节点id）。怎么样？
