To update a GraphQL query on button click, you can use a state variable to store the query parameters and update them when the button is clicked. Here's an example of how you can achieve this using React:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
import React, { useState } from 'react';
import { useQuery } from '@apollo/client';
import { YOUR_QUERY } from './queries';
const App = () => {
const [queryVariable, setQueryVariable] = useState('initialValue');
const { data, loading, error } = useQuery(YOUR_QUERY, {
variables: { queryVariable },
});
const handleButtonClick = () => {
setQueryVariable('newValue');
};
if (loading) return <p>Loading...</p>;
if (error) return <p>Error: {error.message}</p>;
return (
<div>
<button onClick={handleButtonClick}>Update Query</button>
<p>{data && data.field}</p>
</div>
);
};
export default App;

In this example, we have a state variable queryVariable that stores the value of the query parameter. When the button is clicked, the handleButtonClick function updates the queryVariable to a new value. The GraphQL query is then executed with the updated variable value, and the data is displayed in the component.
Make sure to replace YOUR_QUERY with your actual GraphQL query and update the query structure according to your needs.
