我有两个组件。从 componentA 我正在获取roles字段的值并使用此值我需要为users.

componentA的结构是这样的：

[
  {
    "id": "507f1f77bcf86cd799439011",
    "title": "admin",
    "status": "active"
  },
  ...
]

componentB 的结构是这样的，我在其中获取角色数据，当我创建另一个记录时，应该像这种格式那样插入角色的值。

[
  {
    "id": "507f1f77bcf86cd799439017",
    "email": "admin@admin.com",
    "roles": {
      "id": "507f1f77bcf86cd799439011",
      "title": "admin",
      "status": "active"
    }
  },
  ...
]

=> 用户插入组件以插入记录。

import { BootstrapTable, TableHeaderColumn } from "react-bootstrap-table";
import RolesField from "./Editor/Roles/Field";

class UserInsertRow extends React.Component {
  constructor(props) {
    super(props);
    this.roles = [];
    this.getRoles();
  }

  customRoleField = (
    column,
    attr,
    editorClass,
    ignoreEditable,
    defaultValue
  ) => (
    <RolesField
      roles={this.roles}
      ref={attr.ref}
      {...this.props}
      editorClass={editorClass}
      ignoreEditable={ignoreEditable}
    />
  );

  render() {
    return (
      <BootstrapTable
        ref="table"
        insertRow={true}
        deleteRow={true}
        pagination={true}
        data={this.props.data}
      >
        <TableHeaderColumn
          dataField="role"
          customInsertEditor={{ getElement: this.customRoleField }}
          customEditor={{
            getElement: this.roleEditor,
            customEditorParameters: { roles: this.roles }
          }}
        >
          Role
        </TableHeaderColumn>
      </BootstrapTable>
    );
  }
}

=> RolesField 组件

import { rolesContext } from "../../Context";
class RolesField extends React.Component {
  constructor(props) {
    super(props);
  }

  getFieldValue = () => rolesContext._currentValue.selectedRoles;

  render() {
    console.log(this.props.roles);
    return (
      <div className="form-group">
        <select
          className="form-control editor edit-select"
          onChange={this.selectRole}
        >
          {this.props.roles.map(name => (
            <option ref={name.id} key={name.id} value={JSON.stringify(role)}>
              {name.title}
            </option>
          ))}
        </select>
      </div>
    );
  }

  selectRole(e) {
    var options = e.target.options;
    var value = [];
    for (var i = 0, l = options.length; i < l; i++) {
        if (options[i].selected) {
            value.push(options[i].value);
        }
    }
    rolesContext._currentValue.selectedRoles = [];
    value.map(value => rolesContext._currentValue.selectedRoles.push(value));
}

export default RolesField;

我用来存储数据的上下文 API。

import React from 'react';
export const roles = {selectedRoles: []};
export const rolesContext = React.createContext(roles);

id: "507f1f77bcf86cd799439123"
role: []

我如何管理字段的<select>标签，roles以便从选定的下拉值中插入的新记录应该是这样的：

{
"id": "507f1f77bcf86cd799439017",
"email": "qqqq@qqqq.com",
"roles": {
  "id": "507f1f77bcf86cd799439123",
  "title": "admin",
  "status": "active"
}
},

PS请裸露这个有点冗长的代码。
