Question

我的模板-我的模板中不需要任何形式（app-multiselect是我们自己的下拉菜单）

   platform :ios, '10.0'
  require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

   #sdk id libs

end

错误：

FrameworksSceneComponent.html：14错误错误：formControlName必须为与父formGroup指令一起使用。您需要添加一个表格组指令并将其传递给现有的FormGroup实例（您可以在类中创建一个）。
function fourdecimalplace(e) {
    var val = this.value;
    var re = /^([0-9]+[\.]?[0-9]?[0-9]?[0-9]?[0-9]?|[0-9]+)$/g;
    var re1 = /^([0-9]+[\.]?[0-9]?[0-9]?[0-9]?[0-9]?|[0-9]+)/g;

    if (re.test(val)) {
        //do something here

    } else {
        val = re1.exec(val);
        if (val) {
            this.value = val[0];
        } else {
            this.value = "";
        }
    }
（forms.js：1558）在FormControlName.push ../ node_modules/@angular/forms/fesm5/forms.js.FormControlName._checkParentType中（forms.js：5979）在FormControlName.push ../ node_modules/@angular/forms/fesm5/forms.js.FormControlName._setUpControl （forms.js：5983）在FormControlName.push ../ node_modules/@angular/forms/fesm5/forms.js.FormControlName.ngOnChanges （forms.js：5905）在checkAndUpdateDirectiveInline（core.js：19337）在checkAndUpdateNodeInline（core.js：27597）在checkAndUpdateNode（core.js：27559）在debugCheckAndUpdateNode（core.js：28193）在debugCheckDirectivesFn（core.js：28153）在Object.eval [作为updateDirectives]（FrameworksSceneComponent.html：14）

有人知道我的模板出了什么问题吗？我想要一个带有2个下拉菜单的子页面，从中选择一些值后，页面上的结果应该会发生变化（从服务中获取数据之后）

Angular8：formControlName必须与父formGroup指令一起使用
