问题是，我的表单无法获取输入数据，并且在提交时不会在控制台中显示其值。
我已经将ngModel放在每个输入元素上。我还在app.module.ts中导入了FormsModule。
这是我的控制台的屏幕截图：Console
HTML：
<preference name="AutoHideSplashScreen" value="false" />
<preference name="SplashScreenDelay" value="8000" />
<preference name="FadeSplashScreenDuration" value="1000" />
<preference name="SplashScreen" value="screen" />
<preference name="ShowSplashScreen" value="true" />
<preference name="ShowSplashScreenSpinner" value="false" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="FadeSplashScreen" value="true" />
