Saya memiliki masalah yang sama dengan tabel html di mana saya memasukkan baris teks dalam kolom. di dalam lingkaran saya membaca objek json dan saya membuat baris khususnya saya memiliki kolom dengan inputtext.
http://reactkungfu.com/2015/09/react-js-loses-input-focus-on-typing/
Saya berhasil menyelesaikannya dengan cara berikut
import { InputTextComponent } from './InputTextComponent';
//import my inputTextComponent
...
var trElementList = (function (list, tableComponent) {
var trList = [],
trElement = undefined,
trElementCreator = trElementCreator,
employeeElement = undefined;
// iterating through employee list and
// creating row for each employee
for (var x = 0; x < list.length; x++) {
employeeElement = list[x];
var trNomeImpatto = React.createElement('tr', null, <td rowSpan="4"><strong>{employeeElement['NomeTipologiaImpatto'].toUpperCase()}</strong></td>);
trList.push(trNomeImpatto);
trList.push(trElementCreator(employeeElement, 0, x));
trList.push(trElementCreator(employeeElement, 1, x));
trList.push(trElementCreator(employeeElement, 2, x));
} // end of for
return trList; // returns row list
function trElementCreator(obj, field, index) {
var tdList = [],
tdElement = undefined;
//my input text
var inputTextarea = <InputTextComponent
idImpatto={obj['TipologiaImpattoId']}//index
value={obj[columns[field].nota]}//initial value of the input I read from my json data source
noteType={columns[field].nota}
impattiComposite={tableComponent.state.impattiComposite}
//updateImpactCompositeNote={tableComponent.updateImpactCompositeNote}
/>
tdElement = React.createElement('td', { style: null }, inputTextarea);
tdList.push(tdElement);
var trComponent = createClass({
render: function () {
return React.createElement('tr', null, tdList);
}
});
return React.createElement(trComponent);
} // end of trElementCreator
});
...
//my tableComponent
var tableComponent = createClass({
// initial component states will be here
// initialize values
getInitialState: function () {
return {
impattiComposite: [],
serviceId: window.sessionStorage.getItem('serviceId'),
serviceName: window.sessionStorage.getItem('serviceName'),
form_data: [],
successCreation: null,
};
},
//read a json data soure of the web api url
componentDidMount: function () {
this.serverRequest =
$.ajax({
url: Url,
type: 'GET',
contentType: 'application/json',
data: JSON.stringify({ id: this.state.serviceId }),
cache: false,
success: function (response) {
this.setState({ impattiComposite: response.data });
}.bind(this),
error: function (xhr, resp, text) {
// show error to console
console.error('Error', xhr, resp, text)
alert(xhr, resp, text);
}
});
},
render: function () {
...
React.createElement('table', {style:null}, React.createElement('tbody', null,trElementList(this.state.impattiComposite, this),))
...
}
//my input text
var inputTextarea = <InputTextComponent
idImpatto={obj['TipologiaImpattoId']}//index
value={obj[columns[field].nota]}//initial value of the input I read //from my json data source
noteType={columns[field].nota}
impattiComposite={tableComponent.state.impattiComposite}//impattiComposite = my json data source
/>//end my input text
tdElement = React.createElement('td', { style: null }, inputTextarea);
tdList.push(tdElement);//add a component
//./InputTextComponent.js
import React from 'react';
export class InputTextComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
idImpatto: props.idImpatto,
value: props.value,
noteType: props.noteType,
_impattiComposite: props.impattiComposite,
};
this.updateNote = this.updateNote.bind(this);
}
//Update a inpute text with new value insert of the user
updateNote(event) {
this.setState({ value: event.target.value });//update a state of the local componet inputText
var impattiComposite = this.state._impattiComposite;
var index = this.state.idImpatto - 1;
var impatto = impattiComposite[index];
impatto[this.state.noteType] = event.target.value;
this.setState({ _impattiComposite: impattiComposite });//update of the state of the father component (tableComponet)
}
render() {
return (
<input
className="Form-input"
type='text'
value={this.state.value}
onChange={this.updateNote}>
</input>
);
}
}
