从react-js-pagination获取分页器以显示在页面上 [英] Getting paginator from react-js-pagination to display on page
本文介绍了从react-js-pagination获取分页器以显示在页面上的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个React应用，它是购物网站的前端.
我有一个产品页面，我正在尝试将react-js-pagination的分页添加到它的底部，这样我就不必一次渲染整个产品列表.
我已遵循 https://www.npmjs实施分页的指南.com/package/react-js-pagination ，但我仍然无法显示它(页面的其余部分显示正确).
有人知道为什么吗?
请在下面查看我的整个页面的代码:

谢谢.
解决方案
好，所以，如果您阅读我对Leonel答案的评论，您会发现我确实设法从react-js-paginator中获取了分页器，但仍然无法显示使它正常工作.
我改用了自己的自定义基本分页器组件.
请在下面找到我制作的分页器组件:
import React from 'react';
class Paginaton extends React.Component {
render () {
return (
<div className="row">
<div className="pagination">
<button id="prevPage" className="btn" disabled={this.props.disabled1} onClick={() => this.props.onclick1()}>prev</button>
<button id="nextPage" className="btn" disabled={this.props.disabled2} onClick={() => this.props.onclick2()}>next</button>
</div>
</div>
)
}
}
export default Paginaton;
如您所见，这只是一个上一个按钮和一个下一个按钮.
然后，我在容器组件中确保仅将需要激活的按钮显示为激活状态，而将不需要激活的按钮显示为未激活状态.这样可以确保在产品首页上的上一个不是可点击的选项，而在产品首页上的下一个则不是可点击的选项.我还确保向该组件添加一个关键"道具，该道具对于该组件所显示的路线是唯一的.这是必需的，因为我的分页依赖于我在声明"activePage"的组件中设置的状态，因此当我转到另一种产品的页面时(例如，从套件产品到坦克产品)，组件将重新安装(因为两条路由都呈现相同的组件，并且所呈现的产品由路由参数决定)，并且状态将恢复为其初始状态({activePage:1}).
请参阅下面的容器组件:
import React from 'react';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';

I have a react app which is the front end for a shopping site.
I have a products page and I am trying to add pagination from react-js-pagination to the bottom of it so that I do not have to render the entire list of products at once.
I have followed the guidlines on implementing the pagination from https://www.npmjs.com/package/react-js-pagination but I still cannot get it to display (the rest of the page displays properly).
Can anybody see why?

解决方案
Ok so if you read my comments on Leonel's answer you will see that I did manage to get the paginator from react-js-paginator to display but could still not get it to work.
I made my own custom basic paginator component instead.
please find the paginator component that i made below:
import React from 'react';
class Paginaton extends React.Component {
render () {
return (
<div className="row">
<div className="pagination">
<button id="prevPage" className="btn" disabled={this.props.disabled1} onClick={() => this.props.onclick1()}>prev</button>
<button id="nextPage" className="btn" disabled={this.props.disabled2} onClick={() => this.props.onclick2()}>next</button>
</div>
</div>
)
}
}
export default Paginaton;
As you can see this is just a prev button and a next button.
I then, in the container component, made sure that only the button which was required to be active was shown as active and the button that was not required to be active was shown as inactive. this made sure that prev was not a clickable option when on the first page of products and next was not a clickable option when on the last page of products.
I also made sure to add a 'key' prop to the component that was unique to the route that the component was displayed on. This was needed because my pagination relies on a state that I have set in the component which declares the 'activePage' so that when I would go on to a page of products of another type (from kits products to tanks products for example), the component would remount (since both routes render the same component, with the products rendered being decided by the route parameters) and the state would revert to its initial state ({activePage: 1}).
Please see the container component below:
import React from 'react';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';
import changeBrandFilter from '../actions/changeBrandFilter';
import changePriceFilter from '../actions/changePriceFilter';

title={overview.title}
text={overview.text}
image={overview.imageSource}
alt={overview.imageAlt}
