!! Filter Operators for Accessing JSON Data
|
|
|
|
The following filter operators allow values to be read from JSON data:
|
|
|
|
* <<.olink jsonget>> to retrieve the values of a property in JSON data
|
|
* <<.olink jsontype>> to retrieve the type of a JSON value
|
|
* <<.olink jsonindexes>> to retrieve the names of the fields of a JSON object, or the indexes of a JSON array
|
|
* <<.olink jsonextract>> to retrieve a JSON value as a string of JSON
|
|
|
|
!! Text References for Accessing JSON Data
|
|
|
|
[[Text references|TextReference]] are a simple shortcut syntax to look up the value of a named property. For example, if a [[DictionaryTiddler|DictionaryTiddlers]] called `MonthDays` contains:
|
|
|
|
```
|
|
oct:31
|
|
nov:30
|
|
dec:31
|
|
```
|
|
|
|
... then `{{MonthDays##nov}}` will resolve to the value `30`.
|
|
|
|
The same is true if `MonthDays` is a [[JSONTiddler|JSONTiddlers]] with the following content:
|
|
|
|
```
|
|
{"oct":31,"nov":30,"dec":31}
|
|
```
