jsonKeys
$jsonKeys[]
$jsonKeys returns the key names of a JSON object, joined by a separator. It does not depend on $jsonForEach (use $jsonKey for the current key of a loop). The document is not modified.
Syntax
bdfd
$jsonKeys[(key);(...);(separator)]Parameters
- With no argument, the keys of the whole document are returned, separated by
,. - With one argument, it is the path (not a separator) and the separator is
,. - With two or more arguments, the last one is the separator (used as written, it can be empty) and the preceding ones are the path.
- The path is given as separate arguments, one per level (no dot notation:
a.bis a single key nameda.b). Surrounding spaces are removed and empty arguments are skipped. A whole-number argument selects an element when the current value is an array; otherwise it is used as an object key. At most 100 arguments are accepted in total.
Return Value
- The key names of the object at the path (only that level, not nested keys), in document order, joined by the separator.
- An empty string if the value at the path is not an object (an array, a string, a missing path…).
