• javascript
• react-native

• Can you add some code for the button that you've defined? – Pritish Vaidya Commented Aug 16, 2018 at 9:05

Here is a plete implementation of one button pressing another.

import React from "react"
import { View, Button  } from 'react-native';

const someButtonClick = () => {
    console.log("button was pressed");
}

export class PressButton extends React.Component {
    constructor(props) {
        super(props);
        this.state = {}
    }
    clickButton() {
        this.button.props.onPress();
    }
    render() {
        return (
            <View>
                <Button title="another button" 
                    onPress={() => { this.clickButton()}}
                />
                <Button title="some button" testID='someButton' 
                onPress={() => { someButtonClick() }}
                    ref={(button) => {this.button = button; }}
                />          
            </View>
        )
    }
}

Note the following

• you need a ref in order to access the button.
• onPress() is the correct method in React Native, not click()
• the event handlers are in props.

You need to create a ref.

<Button id={buttonId}
  onClick={e => console.log(e.target)}
  ref={(button) => { this.myButton = button; }}
  // Or something like this:
  ref={ponent => this.myButton = ponent}
/>

And then you can access that ref somewhere else in your code:

myFunction = () => {
  this.myButton.click()
}

const uploadbtn = useRef();

I am hiding this button to press it programmatically

 <Button
    ref={uploadbtn}
    buttonStyle={{ width: 0, height: 0, opacity: 0, display: "none" }}
    onPress={pickImage}
  />

And then use a function like this to press the button

  const test = () => {
    uploadbtn.current.handleOnPress();
  };

Try this in render code.

<div className="container" hidden >
   <button onClick={this.submit} ref={(button) => { this.btn = button }} />
</div>

in function

btn = () => {
   this.btn.click()
}

in else code

this.btn()

in render() function

 <button type='button' onClick="{this.btnClickFunc.bind(this)}">buton</button>

and

 function btnClickFunc(e){
    var value = e.target.value;

    }

I Hope worked for you
