I have a list of items and want to iterate over them, create a div block with a button and if the user clicks on the button send this data to a function and then database. However with my code, instead of the item data, I only send undefined.
import React, {useState, useEffect} from 'react';
import './App.css';
import allItemsList from './allItemsList.json'
function App() {
const itemsList = allItemsList[0].itemslist
function addDemoButton (currentItem) {
///how do i pass the currentItem variable here to this function?
}
return (
<div className="App">
<div className="itembox">
{itemsList.map((currentItem ) => (
<div >
<h6>{`${currentItem}` }</h6>
<p>some information here</p>
<button onClick={(currentItem) => addDemoButton()}>Free Demo</button>
</div>
))}
</div>
</div>
);
}
this is the allitemslist.json that i import as allItemsList :
[
{
"itemslist": ["item1", "item2", "item3"]
}
]
In your code,
addDemoButton()
is empty without any parameter.
I believe you should put currentItem inside the function and called it.
addDemoButton(currentItem);

Just add it in addDemoButton
as parameter of method
return (
<div className="App">
<div className="itembox">
{itemsList.map((currentItem ) => (
<div >
<h6>{`${currentItem}` }</h6>
<p>some information here</p>
<button onClick={() => addDemoButton(currentItem)}>Free Demo</button>
</div>
))}
</div>
</div>
);
