Opening pdf file in modal mode?

I was thinking about opening a pdf file in modal mode. current using

@Html.ActionLink("open file", "Download")

open other windows. i want it to fill its div so i can view in modal or overlay.

I'm fine with a jquery solution, and currently my jquery is returning some byte character to me.

function openfile() {
    $.ajax({
        url: '@Url.Action("Download", "mycontroller")',
        type: "POST",
        dataType: "application/pdf",
        success: function (data) {
            $('#showpdf').html(data);
        },
        error: function (err) {
           alert(err)
        }
    });
}

Action in the controller:

public ActionResult Download()
{
    string path = HttpContext.Server.MapPath("/pdf/service_reports/SR26175.pdf");
    return File(path, "application/pdf");
}

Another way to do it is to loop through the pdf path from the json request and then use the object inside the modal div:

<object id="myPdf" type="application/pdf" data="path/file.pdf"></object>

      

        
        
        
      

    


function openfile() {
    $.ajax({
        url: '@Url.Action("Download", "mycontroller")',
        type: "POST",
        dataType: "application/json",
        success: function (data) {
            $('#showpdf').html('<object id="myPdf" type="application/pdf" data="' + data.path +'"></object>');
        },
        error: function (err) {
            alert(err)
        }
    });
}

      

        
        
        
      

    


public ActionResult Download()
{
    string path = HttpContext.Server.MapPath("/pdf/service_reports/SR26175.pdf");
    return Json(new {path = path});
}


EDIT: For a better user experience in different browsers that may not support the tag object

, we could use object

with the tag embed

as a fallback:

<object data="/path/file.pdf" type="application/pdf" width="700px" height="700px">
    <embed src="/path/file.pdf">
        This browser does not support PDFs. Please download the PDF to view it: <a href="/path/file.pdf">Download PDF</a>.</p>
    </embed>
</object>

Assuming you have a controller named home. You can use an iframe like this

<div id='yourModel'>
   <iframe src="/Home/Download"></iframe>
</div>


and use jQuery to show / hide the div.

I tried this, but in the end I did it because I need to show different PDFs that are stored (full path only) in the DB and in the shared folder, then I have to show this one from one to the user, well it works for you!

seemingly the inside of the body.

<div class="row" style="text-align: center;">
                <object id="pdfViewer" data="~/Evidence/PdfFile.pdf" type="application/pdf" width="790" height="500"></object>
                <div style="text-align: center;">
                    <label id="errorTxt"></label>
                </div>
            </div>

on the controller in jsonresult.

            //HERE I GET THE REAL PATH OF THE FILE
            string evidence = _manager.GetEvidence(id);

            //CREATING THE NEW PATH FOR THE FILE
            var path = Path.Combine(Server.MapPath("~/Evidence/"), "PdfFile.pdf");

            //SAVE TEMPORARILY ON EVIDENCE FOLDER INNER THE PROYECT
            //WITH THE NEW NAME 
            System.IO.File.Copy(evidence, path, true);

            //AND JUST RETURN A JSON WITH A MESSAGE TO OPEN MODAL
            return Json("OK",JsonRequestBehavior.AllowGet);

and the js function with jquery

function ShowExistEvidence(id) {
    $.ajax({
        url: "@Url.Action("GetEvidence","ControllerName")",
        type: "POST",
        data: {
            id: id
        },
        success: function (data) {
            if (data === 'OK') {                    
                $("#modViewEvidencia").modal("show");
            } else {
               $("#errorTxt").text('File not found');
               $("#modViewEvidencia").modal("show");
            }

        }
    });
}
