formAttributes property
dynamic
formAttributes
getter/setter pair
Highcharts v11.2.0 and older. An object containing additional key value
data for the POST form that sends the SVG to the export server. For
example, a target
can be set to make sure the generated image is
received in another frame, or a custom enctype
or encoding
can be
set.
With Highcharts v11.3.0, the fetch
API replaced the old HTML form. To
modify the request, now use fetchOptions
instead.
