在子组件中，需要将onReset函数通过props传递给父组件。子组件代码应该类似于以下形式：importReactfrom'react';functionAmenityLabelsSearch(props){//...
在父组件中，可以通过给子组件添加ref属性来获取子组件的引用，然后通过引用调用子组件的方法。例如：import{useRef}from'react';functionParentComponent(){const...
在父组件中调用子组件的onReset函数可以通过ref进行实现。首先，在父组件中创建一个ref引用，然后将该引用传递给子组件作为属性。接下来，您就可以在父组件中通过访问引用并调用onReset()函数来触发子组件的重置操作。以下是示例代码...

在子组件中，你可以使用React.forwardRef()函数来处理ref的传递。这样，你就能够在父组件中通过ref属性将ref挂载到子组件上。下面是一个示例，展示了如何在子组件中接收和使用ref：importReact,{fo...

在父组件中，可以通过使用ref来获取子组件的实例，并调用其方法。首先，在父组件中定义一个ref对象，然后将其传递给子组件作为属性。在子组件中，将该属性绑定到需要访问的元素上。父组件：import{useRef}from're...
在父组件中，可以使用ref来获取子组件的实例，并调用其方法。首先，在父组件中创建一个ref对象：constchildRef=useRef(null);然后，在子组件上添加ref属性，将其与创建的childRef关联起来：<...
