I am new developer ReactJS, I develop a table with ReactJS on the FrontEnd, NodeJS on BackEnd and MySQL about the database.
I want when I click on the view button on Action column, it will be redirected to another page, which display a list containing the result of the Select query, as below :
ViewCLient.js :
class ViewClient extends Component {
constructor(props) {
super(props);
this.state = {
clients: [],
Code :1111
};
this.toggle = this.toggle.bind(this);
this.state = {
activeTab: '1',
};
}
toggle(tab) {
if (this.state.activeTab !== tab) {
this.setState({
activeTab: tab,
});
}
}
componentDidMount(Code) {
axios({
method: "get",
url: "/app/viewclient/"+Code ,
withCredentials: true,
headers: {
"Access-Control-Allow-Origin": "*",
"Content-Type": "application/json",
Accept: "application/json"
}
})
.then(response => {
if (response && response.data) {
this.setState({ clients: response.data });
}
})
.catch(error => console.log(error));
}
render() {
let { clients } = this.state;
// let { clients } = this.state;
return (
<div className="animated fadeIn">
<Row>
<Col xs="12" md="6" className="mb-4">
<Nav tabs>
<NavItem>
<NavLink
className={classnames({ active: this.state.activeTab === '1' })}

<i className="fa fa-info"></i> <span className={this.state.activeTab === '1' ? '' : 'd-none'}> Détails</span>
</NavLink>
</NavItem>
<NavItem>
<NavLink

onClick={() => { this.toggle('2'); }}

<NavItem>

onClick={() => { this.toggle('3'); }}

</Nav>
<TabContent activeTab={this.state.activeTab} style={{ height:"420px"}}>

{
clients && clients.map(client => (
<li key={client.Code}>

<TabPane tabId="2">

</Row>
</div>
);
}
}
export default ViewClient;
ListClient.js
class ListeClients extends Component {
constructor(props) {
super(props);
this.state = {
clients: []
};
this.handleView = this.handleView.bind(this);
this.handleEdit = this.handleEdit.bind(this);
}
componentDidMount() {
axios({

withCredentials: true,

})
.then(response => {
if (response && response.data) {
this.setState({ clients: response.data });
}
})
.catch(error => console.log(error));
}
/*handleViewB(Code) {

handleView( evt) {
try {
console.log("Voir client")
this.props.history.push('/clients/viewclient/');
// Do something that could throw
}
catch (error) {
this.setState({ error });
}
}
handleEdit(event) {
try {
console.log("Modifier client")
this.props.history.push('/clients/editclient/');
// Do something that could throw

// event.preventDefault;
render() {

let Code = this.state;
var btn = {
backgroundColor: 'Transparent',
backgroundRepeat: 'no-repeat',
border: 'none',
cursor: 'pointer',
overflow: 'hidden',
outline: 'none'
}
var center = {
textAlign: "center"
}
return (
<div className="animated fadeIn">
<Card style={{ height:"420px"}}>
<CardHeader>
<h4>
<strong>
<i className="fa fa-align-justify" /> Tous les clients
</strong>
</h4>
</CardHeader>
<CardBody>
<Table bordered responsive size="sm" style={center}>
<thead >

{
clients.map(client => (
<tr key={client.Code}>
<td>{client.Code} </td>
<td>{client.Prenom}</td>
<td>{client.Nom}</td>
<td>{client.Email}</td>
<td>{client.Telephone}</td>
<td>
<button style={btn} onClick={this.handleView} type="button"><i class="fa fa-eye"></i></button>

</td>

))}
</tbody>
</Table>
</CardBody>
</Card>
</div>
);
}
}
export default ListeClients;
My router.js :
exports.viewclient = function(req, res) {
var Code = req.query.Code;
console.log(req.params);
connection.query('SELECT Code, Prenom, Nom, FAX, Telephone, Email, Adresse1, Adresse2 FROM clients WHERE Code = ?',[req.params.Code], function(error, results, fields) {
if (error) throw error;
res.send(JSON.stringify(results));
console.log(results);
});
}
My server.js :
router.get('/viewclient/:Code', clients.viewclient);
When I run the backend, it works well with Postman, but when I run it with ReactJS, it redirects me to http://localhost:3000/app/viewclient/ but nothing is displayed and the console of the router console.log(req.params) returns { Code: 'undefined' }
How to fix that please ?
http://localhost:300/app/viewclient/. You need to pass the full url to axios.ViewClients.jsor onhandleViewonListeClients.jsurl: "/app/viewclient/"+Codewithurl: "http://localhost:4000/app/viewclient/"?
