el-tree组件使用过滤时，不展示筛选目标的子节点

1.el官方示例过滤方法

const filterNode = (value: string, data: Tree) => {if (!value) return truereturn data.label.includes(value)
}

2.修改后的过滤方法

/*** 树节点过滤*/
const filterNode = (value, data, node) => {if (!value) return true;let parentNode = node.parent;let labels = [node.label];let level = 1;while (level < node.level) {labels = [...labels, parentNode.label];parentNode = parentNode.parent;level++;}return labels.some((label) => label.indexOf(value) !== -1);
};
