Is there a way to create a personalized box based on user input dimensions? For example, if the user specifies 4 columns and 5 rows, can a box of size 4x5 be generated allowing the user to navigate through the boxes using arrow keys?
<input type="number" name="row">
<input type="number" name="column">
<button>Generate Box</button>
This is a rather intricate request, as you are essentially seeking an entire program instead of just assistance with your current program/code.
To guide you in the right direction, here are a few things you will likely need:
Here's a quick snippet of semi-pseudocode that could serve as a starting point:
const MyGridNavigator = () => {
const [gridWidth, setGridWidth] = React.useState(4);
const [gridLength, setGridLength] = React.useState(5);
const [userPosition, setUserPosition] = React.useState([0,0]);
const handleKeyDown = (e) => {
if (e.keyCode == '38') {
// up arrow
setUserPosition([userPosition[0], userposition[1] + 1]);
}
else if (e.keyCode == '40') {
// down arrow
setUserPosition([userPosition[0], userposition[1] - 1]);
}
else if (e.keyCode == '37') {
// left arrow
setUserPosition([userposition[0] - 1, userPosition[1]]);
}
else if (e.keyCode == '39') {
// right arrow
setUserPosition([userposition[0] + 1], userPosition[1]]);
}
}
return (
<div onKeyDown={handleKeyDown}>
{
Array(gridLength).fill().map((y, yIndex) => (
<div>
Array(gridWidth).fill().map((x, xIndex) => (
<div>
{ xIndex === userPosition[0] && yIndex === userPosition[1] ? 'user' : '' }
</div>
))
</div>
))
}
</div>
)
}
