React Form - Form Properties
To change the Form configuration at runtime, call the option(optionName, optionValue) method. This approach is more typical of jQuery.
JavaScript
- $(function() {
- var form = $("#formContainer").dxForm({
- formData: {
- firstName: "John",
- lastName: "Heart",
- phone: "+1(213) 555-9392",
- email: "jheart@dx-email.com"
- }
- }).dxForm("instance");
- $("#checkBoxContainer").dxCheckBox({
- text: 'Disable the Form',
- value: false,
- onValueChanged: function (e) {
- form.option("disabled", e.value);
- }
- });
- });
With Angular, Vue, or React, bind the property that should be changed to a component property.
App.js
- import React from 'react';
- import 'devextreme/dist/css/dx.common.css';
- import 'devextreme/dist/css/dx.light.css';
- import { Form } from 'devextreme-react/form';
- import { CheckBox } from 'devextreme-react/check-box';
- const employee = {
- firstName: 'John',
- lastName: 'Heart',
- phone: '+1(213) 555-9392',
- email: 'jheart@dx-email.com'
- };
- class App extends React.Component {
- constructor() {
- super();
- this.state = {
- isFormDisabled: false
- };
- this.onCheckBoxValueChanged = this.onCheckBoxValueChanged.bind(this);
- };
- render() {
- return (
- <div>
- <Form
- formData={employee}
- disabled={this.state.isFormDisabled} />
- <CheckBox
- text="Disable the Form"
- value={this.state.isFormDisabled}
- onValueChanged={this.onCheckBoxValueChanged} />
- </div>
- );
- }
- onCheckBoxValueChanged(e) {
- this.setState({
- isFormDisabled: e.value
- });
- }
- }
- export default App;
