controlname

The name of the WebBrowser control.

script

The JavaScript to be evaluated. The JavaScript cannot have
statements that show dialog boxes. If a dialog box must be
displayed in JavaScript, the script must be executed
asynchronously.

If there are multiple JavaScript statements, only the last
JavaScript statement will have its result returned.

result

The result of script execution. The execution result is
represented in a JSON string. The supported JavaScript data
types are bool, int, double, string, date, array. When the above
types are mapped to the PowerBuilder data types, they are
boolean, integer, double, string, datetime, array.

For example,

{“type”:”double”,”value”:1585620350123};//returns a
double-type value

{“type”:”string”,”value”:”12d6_1585674123456_74563″};//returns
a string-type value

error

The error information if an error occurs during execution.
The error information is represented in a JSON string. For
example,

{“type”:”error”,”value”:”Uncaught TypeError: Cannot read
property ‘style’ “}
