call
Calls a function in a Cordova plugin and returns a result.
Syntax
ui.Interface.frontCall("cordova", "call",
[plugin-name, function-name [, param1, param2, ... ] ],
[result]
)
- plugin-name - This is the name of the Cordova plugin.
- function-name - This is the name of plugin function to be called.
- param1, param2, ... - Optional parameters to be passed to the Cordova function.
- result - Holds the Cordova function return value.
Usage
The call front call executes synchronously the Cordova plugin function
identified by the plugin-name and the function-name.
The other arguments (param1, param2, …) are arguments for
the Cordova plugin function. Each argument may have a different type like FLOAT,
INTEGER, STRING, RECORD or DYNAMIC
ARRAY (for RECORD and DYNAMIC ARRAY, the runtime system
will do the BDL to JSON conversion automatically).
The front call returns one result variable of type FLOAT,
INTEGER, STRING, RECORD or DYNAMIC
ARRAY, that matches the JSON equivalent of the plugin function result (for
RECORD and DYNAMIC ARRAY, the runtime system will do the JSON to
BDL conversion automatically).
The call Cordova front call is synchronous: This means that the call will not
return until the plugin returns a result. Some functions may not return a result at all (such as
start/stop functions) and therefore would cause the front call to wait forever. Those functions need
to be called asynchroneously with the callWithoutWaiting front call.
TRY/CATCH or WHENEVER ERROR.err_get() function, to identify the reason of the error. For more details about
front call error handling, see ui.Interface.frontCall().Example
