Initially, my controller action accepts GET. When my data grew, I was forced to move to POST method to be able to send larger data. My controller action is as follows:
[HttpPost]
public ActionResult ClausesPdf(MyArrayModel obj)
{
...
return File(pdf, "application/pdf", "file.pdf");
}
How can I call this action and download the file using javascript?
Update: I realized that my original answer about AJAX was not entirely accurate since there is no way to return a file from an AJAX call. I suggest that you look at this SO question: Download Excel file via AJAX MVC. I believe @CSL has a good answer that is similar to what you want.
My answer is not plain javascript. This is an AJAX call in jQuery on how it could be done there:
$.ajax({
url: urlControllerAction,
type: 'POST',
cache: false,
data: //your parameter data here
})
.done(
function(result, textStatus, jqXHR) {
//do something with the "result"
}
)
.fail(
//what should be done if something goes wrong
);
