I have a json file containing an array with some objects called json.bc shown by fetch() request. I want to sort all the objects based on total field but the data will be sort in every page not all the pages.How can I sort them?
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
data: [],
library: null,
perPage: 20,
currentPage: 1,
maxPage: null,
}
}
componentDidMount() {
fetch('/json.bc', {
method: 'get',
})
.then(response => response.text())
.then(text => {
let Maindata = JSON.parse(text.replace(/\'/g, '"'))
this.setState(state => ({
...state,
data: Maindata
}), () => {
this.reorganiseLibrary()
})
}).catch(error => console.error(error))
}
reorganiseLibrary = () => {
const { perPage, data } = this.state;
let library = data;
library = _.chunk(library, perPage);
this.setState({
library,
currentPage: 1,
maxPage: library.length === 0 ? 1 : library.length
})
}
// Previous Page
previousPage = event => {
this.handleClick(event)
this.setState({
currentPage: this.state.currentPage - 1
})
}
// Next Page
nextPage = event => {
this.handleClick(event)
this.setState({
currentPage: this.state.currentPage + 1
})
}
// handle per page
handlePerPage = (evt) =>
this.setState({
perPage: evt.target.value
}, () => this.reorganiseLibrary());
// handle render of library
renderLibrary = () => {
const { library, currentPage } = this.state;
if (!library || (library && library.length === 0)) {
return <div>NoResult</div>
}
return library[currentPage - 1].sort((a, b) => a.total - b.total).map((item, i) => (
<div className="Item">
{item.total}
</div>
))
}
render() {
const { library, currentPage, perPage, maxPage } = this.state;
return (
<div>
{this.renderLibrary()}
<ul id="page-numbers">
<li className="nexprevPage">
{currentPage !== 1 && (
<button onClick={this.previousPage}><span className="fa-backward"></span></button>
)}
</li>
<li className="controlsPage activeCnt">{this.state.currentPage}</li>
<li className="restControls">...</li>
<li className="controlsPage">{this.state.maxPage}</li>
<li className="nexprevPage">
{(currentPage < maxPage) && (
<button onClick={this.nextPage}><span className="fa-forward"></span></button>
)}
</li>
</ul>
</div>
)
}}
ReactDOM.render(<App />, document.getElementById('Result'))
renderLibraryfunction.
