Question

有人可以帮我用从http调用（按需）加载的数据来创建此动态表单吗？没有按需数据的代码的工作示例在这里 https://stackblitz.com/edit/github-gaztsv

，我尝试按一下按钮即可加载数据，但这种方法不起作用，请在下面找到它 https://stackblitz.com/edit/github-gaztsv-1azc56?file=src%2Fapp%2Fcomponents%2Fdynamic-form%2Fdynamic-form.component.ts

和我提到的文件是这个 https://medium.com/@mail.bahurudeen/create-a-dynamic-form-with-configurable-fields-and-validations-using-angular-6-994db56834da

您的问题是您创建了一种用于加载字段的方法，但是您没有调用它，因此未加载表单。为此，您需要执行以下操作：在您的app.component.ts上，您需要

implements OnInit

，您需要在

上加载方法

ngOnInit(){
   this.loadvalues()
}

像这样加载组件时，角形将填充您的表单！如果您希望通过按钮执行此操作，请执行以下操作：例如，在您的app.component.ts上获取一个布尔变量，您可以这样做：visible: boolean = false; 然后loadvalues(){ this.visible = true; } 格式为：<dynamic-form [fields]="regConfig" (submit)="submit($event)" *ngIf="visible"> </dynamic-form>

如果您想显示和隐藏在同一按钮中，请执行以下操作：

loadvalues(){
    if(this.visible)
    {
      this.visible = false;
    }else{
     this.visible = true;

    }
}

另外，您需要在顶部加载字段。

 regConfig: FieldConfig[] = [
   {
      type: "input",
      label: "Username",
      inputType: "text",
      name: "name",
      validations: [
        {
          name: "required",
          validator: Validators.required,
          message: "Name Required"
        },
        {
          name: "pattern",
          validator: Validators.pattern("^[a-zA-Z]+$"),
          message: "Accept only text"
        }
      ]
    },
    {
      type: "input",
      label: "Email Address",
      inputType: "email",
      name: "email",
      validations: [
        {
          name: "required",
          validator: Validators.required,
          message: "Email Required"
        },
        {
          name: "pattern",
          validator: Validators.pattern(
            "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$"
          ),
          message: "Invalid email"
        }
      ]
    },
    {
      type: "input",
      label: "Password",
      inputType: "password",
      name: "password",
      validations: [
        {
          name: "required",
          validator: Validators.required,
          message: "Password Required"
        }
      ]
    },
    {
      type: "radiobutton",
      label: "Gender",
      name: "gender",
      options: ["Male", "Female"],
      value: "Male"
    },
    {
      type: "date",
      label: "DOB",
      name: "dob",
      validations: [
        {
          name: "required",
          validator: Validators.required,
          message: "Date of Birth Required"
        }
      ]
    },
    {
      type: "select",
      label: "Country",
      name: "country",
      value: "UK",
      options: ["India", "UAE", "UK", "US"]
    },
    {
      type: "checkbox",
      label: "Accept Terms",
      name: "term",
      value: true
    },
    {
      type: "button",
      label: "Save"
    }
  ];

我希望这会有所帮助！
