The question appears to describe a situation where you have a JSON data structure, and you'd like to retrieve the value corresponding to metric.label.store
in JavaScript. Assuming that context.panel.data
is your JSON object, here is how you can retrieve the value:
// Assuming context.panel.data is your JSON object
const result = context.panel.data.metric.label.store;
// Log the result to see the value
console.log(result);
What this does:
- Access the Object Property: It navigates through the hierarchical properties of the JSON object by following the keys (
metric
->label
->store
). - Retrieve the Value: It fetches the value associated with the
store
key withinlabel
andmetric
.
Notes:
- If any of the intermediary keys (e.g.,
metric
orlabel
) are not defined, the above code will throw an error. To prevent this, you can use optional chaining (?.
):
const result = context.panel.data.metric?.label?.store;
// Log the result (will be undefined if `store` or its parents don't exist)
console.log(result);
Using ?.
, JavaScript will safely return undefined
instead of throwing an error if any part of the chain doesn't exist.
Example:
If context.panel.data
contains this structure:
{
"metric": {
"label": {
"store": "BLAH"
}
}
}
The above JavaScript code will log "BLAH"
to the console.
