Question

我正在练习使用Angular处理表单，并且我喜欢使用引导程序使事情看起来更漂亮。由于某种原因，引导程序样式将应用于表单的其余部分，但是只有单选按钮显示为默认的HTML样式。

我已经尝试弄乱了放置类名的位置，更改了输入的包装方式，但是没有任何效果。我应该提一下，我正在在线上学习教程，并且我的代码与讲师的完全匹配。然而，他以漂亮的蓝色和白色引导出现，而我的HTML则保持灰色和黑色。我想解决此问题，使其显示为蓝色和白色，请不要回答告诉我它“应该”为灰色和黑色。

HTML

      <form (ngSubmit)="onSubmit()" #f="ngForm">
        <div
          id="user-data"
          ngModelGroup="userData"
        #userData="ngModelGroup">
          <div class="form-group">
            <label for="username">Username</label>
            <input
              type="text"
              id="username"
              class="form-control"
              ngModel
              name="username"
            required>
          </div>
          <div class="form-group">
            <label for="email">Mail</label>
            <input
              type="email"
              id="email"
              class="form-control"
              ngModel
              name="email"
              required
              #email = "ngModel"
            >
          </div>
        </div>
        <div class="radio" *ngFor="let gender of genders">
          <label>
            <input
              class="radio"
              type="radio"
              name="gender"
              ngModel
              [value]="gender">
            {{gender}}
          </label>
        </div>
        <button
          class="btn btn-primary"
          type="submit"
          [disabled]="!f.valid"
        >Submit</button>
      </form>

TypeScript

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  @ViewChild('f') signupForm: NgForm;
  defaultValue = 'teacher';
  answer = '';
  genders = ['male', 'female'];
}

您需要创建一个自定义单选按钮

示例从上面的链接复制

/* The container */
.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

/* Hide the browser's default radio button */
.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

/* Create a custom radio button */
.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
  border-radius: 50%;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
  background-color: #ccc;
}

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #2196F3;
}

/* Create the indicator (the dot/circle - hidden when not checked) */
.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

/* Show the indicator (dot/circle) when checked */
.container input:checked ~ .checkmark:after {
  display: block;
}

/* Style the indicator (dot/circle) */
.container .checkmark:after {
 	top: 9px;
	left: 9px;
	width: 8px;
	height: 8px;
	border-radius: 50%;
	background: white;
}
