由 不想你离开。 提交于 2019-12-08 13:15:02
问题 I am not able to understand how to connect two different components with the redux store. Following is what I tried: View.js import React from 'react'; import {View, Text, Button} from 'react-native'; import {Actions} from 'react-native-router-flux'; export default ({counter,actions:{ incrementCounter}}) => ( <View> <Text>Hello from page 1</Text> <Button title='Go to page 2' onPress={() => Actions.page2({})} /> <Button title='Go to page 3' onPress={() => Actions.page3({})} /> <Button title=

Update sibling state based on another clicked sibling ReactJS

由 筅森魡賤 提交于 2019-12-07 10:58:58
问题 Good afternoon, I am having trouble changing the state of components which are siblings. Basically they look like this: <Navigation> <NavEndpt /> About <--- no <NavEndpt /> Blog <NavEndpt /> Projects </Navigation> Each <NavEndpt /> is a link that routes to a different 'page' or route on my website unless it is the first one listed, "About". About I want to be a drop down/lightbox feature something pretty to show off my CSS knowledge. So when one of the links is clicked I want it to go where I

转载 TypeScript 3.0 新功能介绍（二） TypeScript 3.0 新功能介绍（二） New unknown top type TypeScript 3.0引入了一种新的顶级类型unknown。 unknown是任何类型安全的对应物。 任何东西都可以分配给unknown，但是unknown的东西除了本身以及任何没有类型断言或基于控制流的缩小之外的任何东西都不能分配。 同样，如果没有先断言或缩小到更具体的类型，则不允许对unknown操作进行操作。具体看下官方给的例子 // In an intersection everything absorbs unknown type T00 = unknown & null; // null type T01 = unknown & undefined; // undefined type T02 = unknown & null & undefined; // null & undefined (which becomes never) type T03 = unknown & string; // string type T04 = unknown & string[]; // string[] type T05 = unknown & unknown; // unknown type T06 = unknown &

Specify/Set width and height on a react-boostrap modal

由 蹲街弑〆低调 提交于 2019-12-06 23:18:35
问题 How can I apply a dynamic width and height to a react-bootstrap modal window? I have checked the react-bootstrap docs here but could not figure out how to do that. Actually the value of width and height props would be dynamic (could be any values) as this will be a reusable component in my app (to be used on many pages) thus can't apply width/height through some CSS class. 'bsSize' property as mentioned in docs also not working, although predefined sizes of xs, md, lg is not what I exactly

forEach over es6 Map in JSX

由 廉价感情. 提交于 2019-12-06 19:04:44
问题 I had a javascript array that was rendering components using array.map . I switched this array to an es6 Map in order to be able to use key-value pairs to find items more easily, and switched from a .map to a forEach over the Map. Inside the forEach I call a render method that returns a React component, but it isn't being rendered. How do I render a component inside the forEach ? <div className='gallery__items'> {resultsByGuid.forEach((result, index) => { key++; this.renderGalleryItem(result,

ternary operator inside map

由 那年仲夏 提交于 2019-12-06 10:03:29
I'm working on a webapp where the user views a list of items and can mark certain items as favourites. The favourites are provided as an array of ID's with a prop (this.props.favourites). To prevent duplicate entries I want to replace the 'add to favourites' button with a 'delete from favourites' button if the item.id is already in the this.props.favourites array. However, the ternary If statement I've made crashes on a syntax error. Yet I thought I followed the official example ( https://reactjs.org/docs/conditional-rendering.html ) pretty closely. This is the code that I used: render() {
