js获取treeview的值

function getTreeValues(treeViewId) {
    const treeView = document.getElementById(treeViewId);
    const values = [];

    function traverse(node) {
        if (node.nodeType === Node.ELEMENT_NODE && node.classList.contains('tree-node')) {
            // 假设每个节点的值存储在一个名为 'data-value' 的属性中
            const value = node.getAttribute('data-value');
            if (value) {
                values.push(value);
            }
        }

        // 遍历子节点
        for (let child of node.children) {
            traverse(child);
        }
    }

    traverse(treeView);
    return values;
}

// 使用示例
const treeValues = getTreeValues('myTreeView');
console.log(treeValues);

document.getElementById('myTreeView').addEventListener('click', function(event) {
    const target = event.target;
    if (target.classList.contains('tree-node')) {
        const value = target.getAttribute('data-value');
        console.log('Selected value:', value);
    }
});
