使用复选框反应 TypeScript MultiSelector

Question

我正在尝试使用 React typescript props 创建一个搜索表单 event.I 已经完成了一半，但现在卡在了一个复选框 multiSelector 上，我不知道如何实现 it.i 已经用谷歌搜索了很多但在 return 中一无所获。这是我的代码。

我正在使用常见的打字稿道具事件 onChange 来设置我搜索中的所有值 Api 对象。

任何人都可以用代码或文档帮助我如何实现 React Typescript props 事件的 multiSelector 复选框。

1.here是我搜索的结构=>

enter code here

let columns = useMemo(
    () => [
        {
            Header: "Name", accessor: "username",
            Cell: (props: any) => {
                if (authoritiesList.includes("USR-U")) {
                    let path = "/users/" + props.value;
                    return createClickableLink(path, props.value);
                } else {
                    return <>
                        <span>{props.row.original.username}</span>
                    </>
                }
            },
            FilterOptions: {
                FilterInput:
                    <input type="text" placeholder="Username..." />,
                overrideFilterLabel: "Username",
                overrideFilterAccessor: "username"

            }
        },


        {
            Header: "Role(s)", accessor: "roles", disableSortBy: true,
            Cell: (props: any) => {
                return <>
                    {props.row.original.roles.map((role: any) => {
                        return (
                            <div>
                                <span>{role}</span><br/>
                            </div>)
                    })}
                </>
            },
            FilterOptions: {
                FilterSelect:
                         roleData.items.map((curRole:any)=>{
                            return (
                                <input type="checkbox value= 
                                {curRole.name} /> 
               
                            )
                        })} ,
                overrideFilterLabel: "Roles",
                overrideFilterAccessor: "roles"
            }
        },

    
        },
    ], [customerData,roleData]
)



enter code here

const 选择器 = (state: any) => state.users;

return (
    <div className="m-0 p-0 ">
        <section id="content-wrapper">

            <div className="row">
                <div className="col-lg-12 ml-auto">
                    <Breadcrumb crumbs={crumbs}/>
                    <div className="table_data mt-2">

                        {createSearchButton()}
                        {authoritiesList.includes("USR-C") && createAddButton("/users/create", "Add User")}

                        <DataTable columns={columns}
                                   fetchAction={userActions.getAllData as Dispatch<Action>}
                                   exportAction={userActions.exportData  as Dispatch<Action>}
                                   selector={selector}/>
                    </div>
                </div>
            </div>
        </section>
    </div>
);

}

我想处理此表单的多选复选框事件打字稿。所有表单输入标签目前都在工作，但多选复选框无法将输出输出到查询对象。

这是我的打字稿代码。

for (let column of tableColumns) {
    if (!column.FilterOptions) {
        column.FilterOptions = {};
    }

    if (column.FilterOptions?.FilterSelect) {
        column.FilterOptions.FilterSelect.props.onKeyPress = (event: KeyboardEvent) => {
            event.key === 'Enter' && setApplyFilter(true);
        }

        column.FilterOptions.FilterSelect.props.onChange = (event: React.ChangeEvent<HTMLSelectElement>) => {
            updateFilterQuerySelect(column, filterQuery, setFilterQuery, event);
        }
    }

    if (column.FilterOptions?.FilterInput) {
        column.FilterOptions.FilterInput.props.onKeyPress = (event: KeyboardEvent) => {
            event.key === 'Enter' && setApplyFilter(true);
        }

        column.FilterOptions.FilterInput.props.onChange = (event: React.ChangeEvent<HTMLInputElement>) => {
            updateFilterQuery(column, filterQuery, setFilterQuery, event);
        }
    }
}

这里是函数 updateFilterQuery

const updateFilterQuery =（列：DataTableColumn，filterQuery：任何，setFilterQuery：函数，事件：React.ChangeEvent）=> {

let tempQuery: any = {...filterQuery};

let key: string = column.FilterOptions?.overrideFilterAccessor || column.accessor;
let value: any = event.target.value;

if (event.target.value == "on" && event.target.checked != undefined) {
    value = event.target.checked;
}

if (event.target.value == undefined) {
    delete tempQuery[key];
} else {
    key === 'phone' ? tempQuery[key] = getUnformattedPhoneNumber(value)
        :
        tempQuery[key] = value;
}

setFilterQuery(tempQuery);

}

这是一个搜索表单，与其他表单类似，它的工作方式与其他表单相同，而且此表单中唯一缺少的部分是现在无法使用的多选器。

您必须将选择状态分离到自定义挂钩中。状态是所选项目的数组。

CodeSandbox

hooks.ts

import React, { useState } from "react";

export const useMultiselect = (initialValue: string[]) => {
  const [selected, setSelected] = useState<string[]>(initialValue);

  const onChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    const value = event.target.value;
    const index = selected.indexOf(value);
    if (index > -1) {
      setSelected([...selected.slice(0, index), ...selected.slice(index + 1)]);
    } else {
      setSelected([...selected, ...[value]]);
    }
  };

  const isSelected = (value: string) => {
    return selected.includes(value);
  };

  return { selected, isSelected, onChange };
};

App.tsx

import { useMultiselect } from "./hooks";

const data = ["Apple", "Orange", "Banana", "Pear", "Peach"];

export default function App() {
  const { selected, isSelected, onChange } = useMultiselect([]);
  return (
    <div>
      <div>Select your favorite fruites!</div>
      <ul style={{ listStyleType: "none" }}>
        {data.map((value) => (
          <li key={value}>
            <input
              id={value}
              type="checkbox"
              value={value}
              checked={isSelected(value)}
              onChange={onChange}
            />
            <label htmlFor={value}>{value}</label>
          </li>
        ))}
      </ul>
      <div>Selected: {selected.join()}</div>
    </div>
  );
}
