I'm new to react, i want to pass an a value as an argument when the user clicks, and also preventDefault, i found this question that suggest using bind i used it as the code below but didnt solve my problem, it gave me the error TypeError: e.preventDefault is not a function.


  constructor(props){
    super(props)
    this.state={
      headline:'',
      articles:[],
      article:[],
    }
  }


componentDidMount(){
  axios.get("http://127.0.0.1:5000/api/v1/news")
  .then(res=>{this.setState({articles:res.data})}
  )
}




browse = (e,id) => {
  console.log(e)
  e.preventDefault()
  console.log(id)
  axios.get("http://127.0.0.1:5000/api/v1/news/"+id)
  .then(res=>{this.setState({article:res.data,});console.log(res.data)})
}


Here's where i use the browse method

  {this.state.articles.map(art=> {return (
                     <tr>
                    <td><a href={art.url}>{art.headline}</a></td>
                    <td>{art.topic}</td>
                    <td>{art.author}</td>
                    <td><button  onClick ={this.browse.bind(this,art._id.$oid)} > Browse </button></td>
                                            </tr>
                                      )})}

Here's the error

Actually, by writing onClick in that way, you are calling the function as the component is rendered and the passed "e" is not the event, so e.preventDefault() is not a function.

For binding onClick without calling it at the runtime and passing "event" you can use the following format as mentioned here:

onClick={(e) => this.browse(e, id)}
