我正在设计一个表单中的React,我有两个类别的下拉菜单。一个是命名为“什么包括”,另一个是“什么是不包括”。现在我想,如果用户选择任何选项从菜单中的“什么包括”,那么该选项(项目)将被禁用在另一个下拉菜单命名为“什么不包括”。
以下是句柄更改和UI的代码:

const [personwhatIncludeItems, setPersonwhatIncludeItems] = React.useState(
    []
  );
  const [personnotIncludeItems, setPersonnotIncludeItems] = React.useState([]);

  const handlenotIncludeItemsChange = (event) => {
    const {
      target: { value },
    } = event;
    setPersonnotIncludeItems(
      // On autofill we get a stringified value.
      typeof value === "string" ? value.split(",") : value
    );
  };
  

  const handlewhatIncludeItemsChange = (event) => {
    const {
      target: { value },
    } = event;
    setPersonwhatIncludeItems(
      // On autofill we get a stringified value.
      typeof value === "string" ? value.split(",") : value
    );
  };
    <div className="col-6 mt-2 mb-2">
                        <FormControl fullWidth>
                          <InputLabel id="multiple-include-label">
                            {" "}
                            Includes
                          </InputLabel>
                          <Select
                            labelId="whatInclude-multiple-checkbox-label"
                            id="whatInclude-multiple-checkbox"
                            multiple
                            value={personwhatIncludeItems}
                            onChange={handlewhatIncludeItemsChange}
                            input={<OutlinedInput label="Tag" />}

                                value={whatIncludeItems}

不确定我是否完全理解逻辑,但如果目标是禁用选项if selected else where,则可能考虑为每个Map选项添加条件disabled(* 如果其他选定状态已经具有该值,则禁用选项 *),可能如下所示:
以下示例的最小化演示:stackblitz
尽管没有标记为MUI,但发布的代码看起来像MUI,因此示例将使用MUI组件,但如果disabled属性受支持,该方法仍可以与其他库一起使用。

  • “包含内容”* 选择:
