My search component returns a mapped list of results based on the input. Depending on the list element clicked, I want to assign it to my current stock state but I am not sure how I would access that specific element.
const selectStock = ()=>{
setSearch("");
setCurrentStock();
}
return (
<div className="searchContainer">
<form className="searchBar">
<input
className="search"
type="text"
placeholder="Search Ticker Symbol"
onChange={handleSearch}
/>
</form>
<div className="searchResults">
<ul>
{/* {stockNames.map((stockname) => {
const { name, symbol} = stockname;
return (
<li className="displaySearch" onClick={selectStock} key={symbol}>
<p>{name} ({symbol})</p>
</li>
);
})} */}
</ul>
</div>
</div>
);
}
First, you'll want to change your selectStock function to accept the stockName to which it should be set. That should be passed to your setCurrentStock function:
const selectStock = (nextStock) => {
setSearch("");
setCurrentStock(nextStock);
}
Then, pass an arrow function through to the onClick function for the row that you select:
<div className="searchResults">
<ul>
{stockNames.map((stockname) => {
const { name, symbol } = stockname;
return (
<li className="displaySearch" onClick={() => selectStock(stockname)} key={symbol}>
<p>{name} ({symbol})</p>
</li>
);
})}
</ul>
</div>
What this does is essentially create a new function for each row that's specific to itself. When that row is clicked, it triggers its own unique onClick, which passes its own stockname value through to selectStock.
You can pass the selectedStock into the selectStock function by making it a ES6 function.
See below:
const selectStock = (selectedStock)=>{
setSearch("");
setCurrentStock(selectedStock);
}
return (
<div className="searchContainer">
<form className="searchBar">
<input
className="search"
type="text"
placeholder="Search Ticker Symbol"
onChange={handleSearch}
/>
</form>
<div className="searchResults">
<ul>
{/* {stockNames.map((stockname) => {
const { name, symbol} = stockname;
return (
<li className="displaySearch" onClick={()=>selectStock(stockName)} key={symbol}>
<p>{name} ({symbol})</p>
</li>
);
})} */}
</ul>
</div>
</div>
);
You can pass other variables in the similar way if required.
