Resolving Repeated Rendering Issue in React ComponentWhen you encounter a situation where a popup component keeps appearing repeatedly due to the main component refreshing multiple times, it's crucial to address this issue to ensure a smooth user experience. Here's a detailed guide on how to troubleshoot and resolve this problem: Insights:
Suggestions for Resolution:
Code Enhancement:Here's an enhanced version of the DataTable component with optimized rendering to prevent the popup from appearing repeatedly: // Updated DataTable component with optimized rendering
const DataTable = (props) => {
const [searchedData, setSearchedData] = useState([]);
const [openPopup, setOpenPopup] = useState(false);
const keys = ['Customer Name', 'Contact Number', 'Contract Number', 'License Key'];
useEffect(() => {
// Fetch data from API and store in searchedData state
setSearchedData(props.data);
}, [props.data]);
const popupResponse = (value) => {
setOpenPopup(false);
if (value) {
console.log('Value is true');
} else {
console.log('Value is false');
}
};
const deleteKey = useCallback(() => {
setOpenPopup(true);
console.log('In delete key');
}, []);
return (
<div className="data-table">
{searchedData.length > 0 ? (
<table className="data-table__table">
<thead>
<tr>
{keys.map((heading, key) => (
<th key={key}>{heading}</th>
))}
<th></th>
</tr>
</thead>
<tbody>
{searchedData.map((data, key) => (
<RowData
rowData={data}
key={key}
uniqueKey={key}
deleteKey={() => deleteKey(key)}
/>
))}
</tbody>
</table>
) : (
<div className="data-table__no-results">No results found.</div>
)}
{openPopup && (
<PopUp className="data-table__popup" open={openPopup} close={popupResponse} />
)}
</div>
);
}; By implementing these suggestions and optimizing the component rendering, you can prevent the popup from appearing repeatedly and ensure a more efficient user interface.

Body
I just started with React and was trying to build some functionalities to understand React better. Here, I am building a search functionality with some fields. On searching, I get a table with the results. In the table, I have a delete field functionality for each row item. On clicking the delete button, a popup should open asking if the user wants to delete it or not, and store the response for further actions.
Here, on click of the delete button, it looks like the popup component is being called twice (maybe based on the number of results currently visible based on the number of log statements printed).
My table component code:
RowData component (call deleteLiscense function to set the state of popup to open):
PopUp component:
I tried using the callback hook on the deleteKey functionality, thinking maybe it is getting redefined for each delete key button present in the table row, which in return getting called the same number of times as the number of row data present, triggering the popup component. But it didn't resolve the issue.
More observations: On clicking any of the delete keys for the second time, the popup log doesn't appear again.
Thanks
