我正在尝试在项目中添加'@progress/kendo-scrollview'包。我得到了以下错误
错误:(SystemJS) XHR错误(404)加载错误: XHR错误(404)加载 at XMLHttpRequest.wrapFn () at ZoneDelegate.invokeTask () at Zone.runTask () at ZoneTask.invokeTask at invokeTask () at XMLHttpRequest.globalZoneAwareCallback ()将加载为“@progress/kendo角”-scrollview: a
我创建了一个函数,它在调用ScrollView时将它滚动到一个设置的位置(接近顶部)。我希望从react-navigation选项卡栏调用该函数。调用该函数很容易,但我很难让它从屏幕组件中与scrollRef通信。
这是我的零食:
您将在App.js中找到这个函数,当按下选项卡栏时会调用该函数:
const onTabPress = () => {
scrollRef.current?.scrollTo({ // how do I get ref={scrollRef} from component.js ScrollView?
y: 0,
animated: tru
在我的mounted = useRef()和return () => mounted.current = false开始时,我尝试过使用useEffect和return () => mounted.current = false,但是我仍然收到以下错误消息:
Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all s
我是反应原生的初学者,我试图建立非常基本的应用程序,我得到了下面的错误
Invariant Violation: View config not found for name div. Make sure to start component names with a capital letter.

我使用将react原生版本从0.61.0升级到0.65.0。
在对package.json文件进行更改、运行npm、清除android中的build文件夹之后,构建就会成功,应用程序将以一个错误的屏幕启动。

我正在尝试动态创建stackLayouts并将它们添加到现有的scrollView中,但得到了一个错误:
JS ERROR TypeError: scrollView.addChild is not a function. (In 'scrollView.addChild(stackLayout)', 'scrollView.addChild' is undefined)
但是,通过使用console.log,它可以看到这两种情况:
StackLayout(10) ScrollView<dates>@diary/diary-page.xml:4:7;
试图通过理解错误转储来更好地了解如何进行调试。例如,我有一个引用错误如下:
ReferenceError: Can't find variable: title

一个实现样式组件和Scroll视图的原生react应用程序正在工作,但给出了以下警告:

我刚开始使用React-Native,在处理array.As的map时遇到了一个问题,所有元素都需要一个唯一的键。我已经在render方法中指定了键,但我仍然收到警告。以下是代码
import React, { Component } from 'react';
import {Text , ScrollView} from 'react-native';
import axios from 'axios';
import AlbumDetail from './AlbumDetail'
export default class
这是我第一次有反应的经验,我在我的程序中有这个问题。你能帮帮我吗?我在应用程序中使用了TMDB。

我看过类似的问题,但似乎没有一个解决方案对我有用,这已经困扰了我两天了。
这个错误似乎来自于将this.props.navigate传递给exerciseList.js,但是我尝试过的一切都不起作用。因此,任何建议都将不胜感激。当我通过exerciseList.js单击单独呈现的文件时,会发生错误。
错误消息:
undefined is not a function (evaluating '_this2.props.navigate('Exercises', { exerciseName:ex})')
