Import all functions from react-simple-captcha
import { loadcaptchaenginge, LoadCanvasTemplate, LoadCanvasTemplateNoReload, validateCaptcha } from 'react-simple-captcha';
Place or (if you do not want 'Reload Captcha' functionality) in your render code in the function ReactHtmlParser()
render() {
return (<div>
<LoadCanvasTemplate />

componentDidMount () {
loadcaptchaenginge(6);
};
Validate captcha by using validateCaptcha(user_captcha_value)
doSubmit = () => {
<! -- let's assume there is an HTML input text box with id 'user_captcha_input' to get user input -->
let user_captcha_value = document.getElementById('user_captcha_input').value;
if (validateCaptcha(user_captcha_value)==true) {
alert('Captcha Matched');
}
else {
alert('Captcha Does Not Match');
}
};
OR
If you don't watch captcha to be reloaded if user enter the wrong value then set second parameter to false validateCaptcha(user_captcha_value, false)
doSubmit = () => {
<! -- let's assume there is an HTML input text box with id 'user_captcha_input' to get user input -->
let user_captcha_value = document.getElementById('user_captcha_input').value;
if (validateCaptcha(user_captcha_value, false)==true) {
alert('Captcha Matched');
}
else {
alert('Captcha Does Not Match');
}
};
Listed are all the options available for react-simple-captcha
Name | Description |
---|---|
< LoadCanvasTemplate /> | It will load the captcha with 'Reload Captcha' functionality. Place between your render code, usage example < LoadCanvasTemplate /> |
< LoadCanvasTemplateNoReload /> | It will load the captcha without 'Reload Captcha' functionality. Place between your render code, usage example < LoadCanvasTemplateNoReload /> |
loadcaptchaenginge(Number_Of_Captcha_Charcters); | Simply paste it in componentDidMount(). Pass number of captcha characters you want to display. |
validateCaptcha(User_Submitted_Value) | Will return true if user submitted value matches with captcha otherwise false. Also will reload captcha if user submitted value is false |
validateCaptcha(User_Submitted_Value, false) | Will return true if user submitted value matches with captcha otherwise false. Will not reload captcha if user submitted value is false |
Let's create a class name CaptchaTest with react simple captcha functionality:
import React, { Component } from 'react';
import { loadcaptchaenginge, LoadCanvasTemplate, LoadCanvasTemplateNoReload, validateCaptcha } from 'react-simple-captcha';
class CaptchaTest extends Component {
componentDidMount () {
loadcaptchaenginge(6);
};
doSubmit = () => {
let user_captcha = document.getElementById('user_captcha_input').value;
if (validateCaptcha(user_captcha)==true) {
alert('Captcha Matched');
loadcaptchaenginge(6);
document.getElementById('user_captcha_input').value = "";
}
else {
alert('Captcha Does Not Match');
document.getElementById('user_captcha_input').value = "";
}
};
render() {
return (<div>
<div className="container">
<div className="form-group">
<div className="col mt-3">
<LoadCanvasTemplate />
</div>
<div className="col mt-3">
<div><input placeholder="Enter Captcha Value" id="user_captcha_input" name="user_captcha_input" type="text"></input></div>
</div>
<div className="col mt-3">
<div><button class="btn btn-primary" onClick={() => this.doSubmit()}>Submit</button></div>
</div>
</div>
</div>
</div>);
};
}
export default CaptchaTest;
Import CaptchaTest in index.js
import CaptchaTest from './captcha_test';
Now replace ReactDOM.render with
ReactDOM.render(<CaptchaTest />, document.getElementById('root'));
Works in every modern browser which has support for canvas element.
