$jsonClear

$jsonClear clears the entire current JSON object from memory. After calling it, all JSON functions return empty until $jsonParse or $jsonSet is called again.

Syntax

$jsonClear

No parameters.

What happens

1. $jsonParse loads a JSON object into memory.
2. $jsonClear wipes the entire object.
3. Any $json, $jsonExists, $jsonStringify, or similar call after this returns empty.

Example 1: Clear and confirm

$nomention
$jsonParse[{"username":"Zubariel"}]
Before: $json[username]
$jsonClear
After: $json[username]

What happens:

1. $jsonParse loads the object.
2. $json[username] returns Zubariel.
3. $jsonClear wipes the object from memory.
4. $json[username] now returns empty.

Output:

Before: Zubariel
After: 

Example 2: Reset between two separate objects

$nomention
$jsonParse[{"name":"Zubariel"}]
Name: $json[name]
$jsonClear
$jsonParse[{"name":"Speshy"}]
Name: $json[name]

What happens:

1. The first $jsonParse loads the first object.
2. $jsonClear removes it so there is no overlap.
3. The second $jsonParse loads a fresh object.
4. $json[name] returns the new value.

Output:

Name: Zubariel
Name: Speshy

Common uses

• Working with multiple JSON objects in one command: clear before parsing the next one
• Resetting state: ensure no leftover data from a previous parse affects the current one

See also

• $jsonParse: to load a new object after clearing
• $jsonUnset: to remove a single key instead of the whole object
