筛选#

¥Filter

根据条件筛选项目。如果项目符合条件，“筛选器”节点会将其传递给“筛选器”节点输出中的下一个节点。如果项目不符合条件，“筛选器”节点将从其输出中省略该项目。

¥Filter items based on a condition. If the item meets the condition, the Filter node passes it on to the next node in the Filter node output. If the item doesn't meet the condition, the Filter node omits the item from its output.

节点参数#

¥Node parameters

创建筛选条件以执行筛选。

¥Create filter comparison Conditions to perform your filter.

¥Ignore Case: Whether to ignore letter case (turned on) or be case sensitive (turned off).

  • 放宽类型验证：是否希望 n8n 根据你选择的运算符尝试转换值类型（已开启）或不转换（已关闭）。当你的节点遇到 "类型错误：" 错误时，请启用此选项。
