    ComfyUI Switch Any Node

    This is a custom node for ComfyUI that provides a dynamic "Switch" for routing purposes. It allows you to define a list of named labels and select one, outputting the corresponding index and label name. This is useful for controlling the flow of your workflow based on a selection.

    Features

    • Dynamic Label Inputs: Start with a single label input. As you fill them in, new empty inputs appear automatically after a refresh.
    • UI Refresh Button: A "Save & Refresh UI" button is included directly on the node. This saves your current labels and reloads the ComfyUI interface in one click, updating the dropdown menu and input fields instantly.
    • No Data Input: This node is purely for routing and does not take any data inputs. It only outputs the selected index (INT) and label (STRING).
    • Persistent Labels: Your list of labels is saved in a JSON file within the node's directory, so they persist across ComfyUI sessions.

    How to Use

    1. Add the Node: Add the Switch Any node to your workflow.
    2. Define Labels:
      • Initially, you will see one input field, label_1. Enter a name for your first route (e.g., "SDXL").
      • To add more labels, you can fill in the next available input field (label_2, etc.).
    3. Save and Refresh:
      • Click the "Save & Refresh UI" button on the node.
      • The page will automatically reload.
    4. Select a Label:
      • After reloading, the select_label dropdown menu will be populated with all the labels you defined.
      • The node will now show all your saved labels plus one new empty input field for the next one.
    5. Get Output: The node will output the 1-based index and the label string of your selection from the dropdown menu.

    Installation

    1. Clone or download this repository.
    2. Place the ComfyUI_Switch folder into the ComfyUI/custom_nodes/ directory.
    3. Restart ComfyUI.

    ComfyUI Switch Any 节点 (中文说明)

    这是一个为 ComfyUI 设计的自定义节点，提供了一个用于路由目的的动态“切换”功能。它允许您定义一个带名称的标签列表并从中选择一个，然后输出对应的索引和标签名。这对于根据选择来控制您的工作流非常有用。

    功能特性

    • 动态标签输入: 从一个标签输入框开始。当您填写后，刷新界面即可自动出现新的空输入框。
    • UI 刷新按钮: 节点上直接集成了一个 "Save & Refresh UI" 按钮。一键即可保存当前所有标签并重新加载 ComfyUI 界面，即时更新下拉菜单和输入框。
    • 无数据输入: 这是一个纯粹的路由节点，不接收任何数据输入。它只输出所选的 index (整数) 和 label (字符串)。
    • 标签持久化: 您的标签列表会保存在节点目录下的一个 JSON 文件中，因此可以在不同的 ComfyUI 会话之间保持不变。

    如何使用

    1. 添加节点: 在工作流中添加 Switch Any 节点。
    2. 定义标签:
      • 最初，您会看到一个输入框 label_1。为您的第一个路由输入一个名称 (例如 "SDXL")。
      • 要添加更多标签，只需填写下一个可用的输入框 (label_2 等) 即可。
    3. 保存并刷新:
      • 点击节点上的 "Save & Refresh UI" 按钮。
      • 页面将会自动重新加载。
    4. 选择标签:
      • 重新加载后，select_label 下拉菜单中将填充您定义的所有标签。
      • 节点现在会显示所有已保存的标签，并额外提供一个新的空输入框供您继续添加。
    5. 获取输出: 节点将输出您从下拉菜单中所选项的 index (从1开始的整数) 和 label (字符串)。
