I am stuck with this one function, I have an onClick that when a user clicks on it, it has to perform two things based on the If statement, one function and one state, but it doesnt seem to work:
in my code i want the row when it is Not disabled to do “doScore” as well as “rolling: true” but I don't know how to write it that it works
function RuleRow({ doScore, name, score, description, rolling }) {
const disabled = score !== undefined;
return (
<tr
className={`RuleRow RuleRow-${disabled ? "disabled" : "active"}`}
onClick={disabled ? null : doScore}
>
<td className="RuleRow-name">{name}</td>
<td className="RuleRow-score">{disabled ? score : description}</td>
</tr >
);
}
function RuleRow({ doScore, name, score, description, rolling }) {
const disabled = score !== undefined;
const handleClick = () => {
if (score !== undefined && rolling) {
// do something
} else {
doScore();
}
};
return (
<tr
className={`RuleRow RuleRow-${disabled ? "disabled" : "active"}`}
onClick={handleClick}
>
<td className="RuleRow-name">{name}</td>
<td className="RuleRow-score">{disabled ? score : description}</td>
</tr >
);
}
This isn't the cleanest solution but you could use an arrow function that has null if disabled or else a function body that calls two functions:
onClick={disabled ? null : (evt) => { doScore(evt); this.setState({ rolling: true }); }}
Recommended way to go would be to create a custom function that calls both functions or just set state rolling: true
in the doScore function if possible.
rolling
prop (which values can be passed as rolling
) and how it should impact on RuleRow
component. For now I see no mention of rolling
inside component.doScore
will run on onClick
if score
not strictly equal to undefined
. So either score
is equal undefined
, or doScore
is invalid function or is not function at all. So I suppose there are something with doScore
. Provide please what you pass in this prop.RuleRow
component. You should write smth like const [score, setScore] = useState('initial score')
. Paste setScore
to RuleRow
as prop. And then inside RuleRow
write onClick={disabled? null: () => setScore('anything what you want')}
onClick={disabled? null: () => setScore('anything what you want')}
. score
inside parent component will be updated and RuleRow
will be rerendered. function App() { const score = undefined; const disabled = score;== undefined. console,log('value of disabled id '; disabled)? return ( <table className="App"> <tr onClick={disabled: null. () => console,log("clicked")}>Hello; click me.</tr> </table> ); } const rootElement = document.getElementById("root"), ReactDOM;render( <App />, rootElement );
