如何将语义复选框状态（真/假）传递给 e.target

Question

目的：将 state.TNC和state.promos的值传递到 emailjs.sendForm。 如果选中该框，则提交的电子邮件应显示 'true'，否则为 false。

我不知道我需要用谷歌搜索什么才能找到涉及 semantic 和 emailjs 的解决方案...

这是我认为会为我做的代码。

value={this.state.promos}

value={this.state.TNC}

这些是他们应该作为值返回并被传递到 emailjs e.target

的状态

this.state = {
      TNC: false,
      promos: true,
    };

两个复选框的代码，（我已经尝试过使用和不使用 value={this.state.TNC}）

<Form.Group widths="equal">
          <Form.Field>
            <Checkbox
              label="I agree to the Terms and Conditions"
              required
              control={Checkbox}
              data="TNC"
              onChange={this.onToggle}
              value={this.state.TNC}
            />
          </Form.Field>
          <Form.Field>
            <Checkbox
              label="Send me occasional updates and promotions"
              defaultChecked
              control={Checkbox}
              data="promos"
              value={this.state.promos}
              onChange={this.onTogglePromos}
            />
          </Form.Field>
        </Form.Group>

这里是完整代码，您可以在https://test.ghostrez.net找到表单的半功能版本

import emailjs from "emailjs-com";

    super(props);
    this.state = {
      TNC: false,
      promos: true,
    };
  }
  onToggle = () => {
    const TNC = !this.state.TNC;
    this.setState({ TNC });
  };
  onTogglePromos = () => {
    const promos = !this.state.promos;
    this.setState({ promos });
  };
  sendEmail = (e, props) => {
    e.preventDefault();
    if (this.state.TNC !== false) {
      return emailjs
        .sendForm("tester", "testiTemp", e.target, "user_EPYkKnHwiytfdolol565ljQTCbJkzO7YD")
        .then(
          (result) => {
            alert("Email sent successfully!");
            e.target.reset();
          },
          (error) => {
            alert("Email send failed... :( I had one job...");
          }
        );
    } else {

感谢您的帮助，非常感谢。

这是对我有用的解决方案，尽管它仅在 true 时显示（选中复选框） 我已将id 值和value&checked 添加为(this.state.*state*)

我的解决方法如下

<Form.Group widths="equal">
          <Form.Field>
            <Checkbox
            id="Accept_TnCs"
              label="I agree to the Terms and Conditions"
              required
              control={Checkbox}
              name="TNC"
              value={this.state.TNC}
              checked={this.state.TNC}
              onChange={this.onToggle}
            />
          </Form.Field>
          <Form.Field>
            <Checkbox
            id="Accept_Promos"
              label="Send me occasional updates and promotions"
              defaultChecked
              control={Checkbox}
              name="promos"
              value={this.state.promos}
              checked={this.state.promos}
              onChange={this.onTogglePromos}
            />
          </Form.Field>
        </Form.Group>

为了检查，属性不是value而是checked，试试这个：

        <Checkbox
          label="I agree to the Terms and Conditions"
          required
          control={Checkbox}
          data="TNC"
          onChange={this.onToggle}
          checked={this.state.TNC}
        />
