Please refer below code
var pdf="xxxxxxx";
$.ajax({
type: "post",
url: "/Corporate/SampleChangeSummary/PDF",
data: JSON.stringify(pdf),
contentType: 'application/json',
dataType: 'json',
error: function (status, xhr) {
}
});
[HttpPost]
public ActionResult PDF(object pdf)
{
.......
}
but it returning pdf is null. What is the problem? Any syntax mistake in my code?
I believe that contentType is what causing the issue. In that script of yours, you were telling your $.ajax() that it is sending JSON string, but you had it sending a .pdf. Instead, just remove contentType line and try it.
Secondly, dataType: 'json' is telling your $.ajax() that it is expecting the response in JSON format. If that's what you are doing, then you dont have to worry about that line.
EDITED:
Found more information - if you wanted to keep contentType then, revise to this: contentType: application/pdf', and add header('Content-type: application/pdf'); on your php file that your $.ajax() is sending to.
Try this:
$.ajax({
type: "post",
url: "/Corporate/SampleChangeSummary/PDF",
data: JSON.stringify({pdf: pdf}),
contentType: 'application/json',
dataType: 'json',
error: function (status, xhr) { }
});
ASP.NET MVC requires you to send a 'key-value' JSON object so it can bind accordingly. Also, change object pdf to string pdf.
contentType: 'application/json; charset=utf8'Try somthing like this
$.ajax({
type: "POST",
url: '/Corporate/SampleChangeSummary/PDF',
data: { pdf: JSON.stringify(pdf) },
success: function (data) {
//do somthing with the result
},
error: function (error) {
alert('Please try again!');
}
});
var pdf="xxxxxxx";
$.ajax({
type: "post",
url: "/Corporate/SampleChangeSummary/PDF",
data: { "pdf" : pdf },
dataType: 'json',
error: function (status, xhr) {
}
});
[HttpPost]
public ActionResult PDF(object pdf)
{
.......
}
you don't need to stringify your pdf because it is already string try to pass it directly to your controller.
