I was wondering how will I reload only the table, not the whole page on reacts. I've tried using history.go(0);
however, it reloads the whole page please check how can I reload it, if I was going to use forceUpdate
, based on research you should avoid using it. I'm trying do an AJAX but I don't know what to put where to put it... it is way different than PHP..
My code for the onclick
:
handleUpdate(id, name, address,department){
const data = {
'Employee_ID': id,
'Employee_Name': name,
'Address': address,
'Department': department
}
return fetch('http://localhost:5118/api/employeedetails/PutEmployeeDetail/'+id, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify(data)
})
.then(function(response) {
console.log(response)
return response.json();
})
.then((result)=> {
var jsonReturnedValue = [...this.state.jsonReturnedValue];
jsonReturnedValue[data].Department = department,
jsonReturnedValue[data].Employee_name = name,
jsonReturnedValue[data].Address = address
this.setState({jsonReturnedValue})
})
.catch(function(error) {
console.log(error);
})
}
code for the render and the table:
render() {
const isEnabled = this.canBeSubmitted();
let {jsonReturnedValue} = this.state;
return(
<div>
<div className="container">
<h1> Listof Employees </h1>
<button className ='btn btn-warning right ' data-toggle="modal" data-target="#AddEmployee"> Add an Employee</button>
<table className= "table table-bordered" id="result">
<tbody>
<tr>
<th>ID</th>
<th>Name</th>
<th>Address</th>
<th>Update</th>
<th>Delete</th>
</tr>
{jsonReturnedValue.map((d,i) => this.renderItem(d,i))}
</tbody>
</table>
</div>
{/*Updating*/}
<div className="modal fade" id="UpdateEmployee" role="dialog">
<div className="modal-dialog">
<div className="modal-content">
<div className="modal-header">
<button type="button" className="close" data-dismiss="modal">×</button>
<h4 className="modal-title">Update Employee</h4>
</div>
<form >
<div className="container">
<div className="modal-body">

<tbody>
<tr>
<td>Name</td>
<td>
<input type="text"

value={this.state.Employee_Name}

<td>
<input type="text"

required
onChange={(e) => this.handleChange(e, "Department")}/>
</td>
</tr>
</tbody>
</table>
</div>
</div>
<div className="modal-footer">
<input type="button" className="btn btn-info" disabled={!isEnabled} onClick = { this.handleUpdate.bind(this, this.state.Employee_ID , this.state.Employee_Name ,this.state.Address ,this.state.Department)} value =" Update Employee" data-dismiss="modal"/>
<button type="button" className="btn btn-default" data-dismiss="modal">Close</button>
</div>
</form>
</div>
</div>
</div>
jsonReturnedValue
should use the index
and not object
. Make use of findIndex
to get the index of the object with Employee_ID = id
in the array
handleUpdate(id, name, address,department){
const data = {
'Employee_ID': id,
'Employee_Name': name,
'Address': address,
'Department': department
}
return fetch('http://localhost:5118/api/employeedetails/PutEmployeeDetail/'+id, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify(data)
})
.then(function(response) {
console.log(response)
return response.json();
})
.then((result)=> {
var jsonReturnedValue = [...this.state.jsonReturnedValue];
var idx = jsonReturnedValue.findIndex((val) => val.Employee_ID == id)
jsonReturnedValue[idx].Department = department,
jsonReturnedValue[idx].Employee_name = name,
jsonReturnedValue[idx].Address = address
this.setState({jsonReturnedValue})
})
.catch(function(error) {
console.log(error);
})
}
