So I'm just playing around with the rick and Morty API and I've never done a ternary with 3 conditions. Mozilla docs say you can, but it's not working for me. The code below shows the characters with the status alive in green and the rest are purple. I want alive to be green, dead to be red, unknown to be purple. I'm using chakra UI if anyone's curious. What am I doing wrong?
<Badge
colorScheme={ c.status === "Alive" ? "green"
: "unknown" ? "purple"
: "red"
}
>
{c.status}
</Badge>
You have your symbols mixed up. Grouping with parentheses, your code is equivalent to
c.status === "Alive" ? "green"
: ("unknown" ? "purple" : "red")
You need instead
c.status === 'Alive'
? 'green'
: c.status === 'unknown' ? 'purple' : 'red'
Or you could use a lookup table instead - it'd be more readable.
const colorsByStatus = {
Alive: 'green',
unknown: 'purple',
dead: 'red'
};
// ...
colorSceme={colorsByStatus[c.status]}
In the second condition, you are using "unknown" which is always true hence the output will always be "purple". Do the following.
let a = { status: "Alive" };
let b = { status: "dead" };
let c = { status: "unknown" };
console.log(
a.status === "Alive" ? "green" : a.status === "unknown" ? "purple" : "red"
);
console.log(
b.status === "Alive" ? "green" : b.status === "unknown" ? "purple" : "red"
);
console.log(
c.status === "Alive" ? "green" : c.status === "unknown" ? "purple" : "red"
);
