First of all, I am not good at English. I am sorry
When I save the pdf file as an attachment using jspdf, can I save only 3 sheets from the beginning?
I can't find an example of saving only a specific page, so I'm asking you a question
My guess is that when you press the registration button, you can save it as 3 sheets only if the extension of the attachment is pdf
My guess ->
Register after user adds attachment form submit
If the storage extension is pdf in the saved api,
2-1. Read jsPDF and bring only the first 3 pages to make a new pdf
2-2. Save only 3 pages
function fnInsert(){
if($("#title").val() === ''){
alert("Please enter a title.");
return false;
}
var ext = $('[name=upload_0]').val().split('.').pop().toLowerCase();
if($.inArray(ext, ['pdf']) == -1) {
/* When pdf, read jsPDf and bring only the first 3 pages to create a new pdf */
}
/* Save to 3-page pdf DB */
$("#aform").attr({action:"/cms/data/insertDataMgt.do", method:'post'}).submit();
}
I don't know what to do with the annotated part

I know it's possible to display a Google Sheet as HTML using the spreadsheet ID and GID, i.e.:
https://docs.google.com/spreadsheets/d/SPREADSHEET_ID/gviz/tq?tqx=out:html&tq&gid=GID
But in order to view that, you have to know the URL of the sheet. What I'm wondering is whether it's possible to display this HTML version of the sheet but without revealing the URL of the sheet?
Manually
To retrieve a Spreadsheet in HTML format you can export it accordingly by clicking on File -> Download -> Web Page. That will get you a zip file with the HTML of your Spreadsheet that you can rename as you like without revealing the Spreadsheet ID.
With Apps Script
You can also automate this process creating an Apps Script function that for instance gets triggered every time you click on an inserted button (to do this you can simply click on the menu bar Insert -> Drawing and the on the three dots of the top right of this button click on assign script and set it to the name of your function).
The following function will display a modal dialog on the Spreadsheet when run that if the user clicks on Download it will automatically download the zip file with the Spreadsheet in HMTL format. This function has self explanatory comments :
function downloadHTML() {
// Get ID of the Spreadsheet
var id = SpreadsheetApp.getActive().getId();
// Get the download URL of this Spreadshet in format HTML on the background
var url = "https://docs.google.com/a/mydomain.org/spreadsheets/d/" + id + "/export?exportFormat=zip&access_token=" + ScriptApp.getOAuthToken();
// Download when clicked on the button of the opened dialog
var html = '<input type="button" value="Download" onClick="location.href=\'' + url + '\'" >';
// create an HTML output from the given string
var dialog = HtmlService.createHtmlOutput(html);
// Show a modal dialog on the Spreadsheet UI when the function is run with the Title download
SpreadsheetApp.getUi().showModalDialog(dialog, "Download");
}

I am stuck at last point of my application, i am supposed to display user form in PDF which works fine on desktop browsers as they has pdf viewer built in, but for Android / iOS its not working as pdf viewer is missing.
So i was trying to use PDF.js to display it, (to be honest, this is very widely used but documentation is lacking), only catch is i am getting data in base64 format. PDF.js has example on site which shows how to render the base64 data but its not PDF, for that displaying PDF as "PDF" i need to user their "viewer.html" but that does not take base64 data?
closest i have come to Pdf.js: rendering a pdf file using base64... on stack overflow, but i dont know how to use it after PDFJS.getDocument(pdfAsArray)?.
Other link that came across was other link
I dont want to rely on Google / Third party PDF viewer as i dont know how long they will support this.
There are no end-to-end answers on this topic in community so here is my attempt to put something here. (maybe it will help others)
Okay, PDF.js is one way of showing PDF in browser, specially when you don't want to rely on PDF plugin to be installed. In my case, my application generates report in PDF and that can be viewed before downloading but on handheld devices it was not working because of missing PDF viewer plugin.
In my case PDF was sent to browse in base64 string, that I can use to display PDF with <object src="base64-data"...></object>. This works like charm on Chrome / FF but switch to mobile view and it stops working.
<object type="application/pdf" id="pdfbin" width="100%" height="100%" title="Report.pdf">
<p class="text-center">Looks like there is no PDF viewer plugin installed, try one of the below approach...</p>
</object>
In above code it will try to show the PDF or fall back to <p> and show error message. And I Was planning to add the PDF viewer at this point, PDF.js was the choice but was not able to display it. One example on PDF.js with Base64 data shows how to do this but that renders it as an Image not PDF, and I was not able to find solution for that and hence the question, here is what I did,
First add the JavaScript code to convert base64 to array
convert to blob and use viewer.html file packaged with PDF.js to display it as PDF
In case if you are wondering why base64 data, then answer is simple I can create the PDF, read it, send the data to client and delete the file, I don't have to run any cleaner service/cron job to delete generated PDF files
Few Things To Note
Below code is using Flask + Jinja2, change the way base64 is read in html if you are using something else
viewer.html needs to be changed to have required js & css files in proper location (by default their location is relative; you need them to be referred from static folder)
viewer.js looks for pdf.worker.js in predefined location, change that in case its throwing error as above file not found.
viewer.js might throw file origin does not match viewer error in that case as a quick fix comment the code which throws this error and see if that solves the issue (look for that error in viewer.js)
I am not the author of below code, I have just put it together from different places.
Now to the code (so PDF will be displayed when user clicks on button with id="open_id")
Jquery
var pdfDataX = '{{ base64Pdf }}';
var BASE64_MARKER = ';base64,';
PDFJS.workerSrc = "{{ url_for('static', filename='js/pdf.worker.js') }}";
$('#open_id').click(function() {
PDFJS.disableWorker = true;
var pdfAsDataUri = "data:application/pdf;base64," + pdfDataX ;
PDFJS.workerSrc = "{{ url_for('static', filename='js/pdf.worker.js') }}";
// Try to show in the viewer.html
var blob = base64toBlob(pdfDataX, 'application/pdf');
var url = URL.createObjectURL(blob);
var viewerUrl = "{{ url_for('static', filename='viewer.html') }}" + '?file=' + encodeURIComponent(url);
$('#pdfViewer').attr('src', viewerUrl);
// Finish
var mdObj = $('#pdfbin');
mdObj.hide();
mdObj.attr('data', pdfAsDataUri);
mdObj.show();
$('#myModal').modal();
});
var base64toBlob = function(b64Data, contentType, sliceSize) {
contentType = contentType || '';
sliceSize = sliceSize || 512;
var byteCharacters = atob(b64Data);
var byteArrays = [];
for (var offset = 0; offset < byteCharacters.length; offset += sliceSize) {
var slice = byteCharacters.slice(offset, offset + sliceSize);
var byteNumbers = new Array(slice.length);
for (var i=0; i<slice.length; i++) {
byteNumbers[i] = slice.charCodeAt(i);
}
var byteArray = new Uint8Array(byteNumbers);
byteArrays.push(byteArray);
}
var blob = new Blob(byteArrays, {type: contentType});
return blob;
}
$('.save').click(function(e) {
e.preventDefault();
var blob = base64toBlob(pdfDataX, 'application/pdf');
saveAs(blob, 'abcd.pdf'); // requires https://github.com/eligrey/FileSaver.js/
return false;
});
HTML

I have program which stores crystal reports (in bytes in database) and then gives a list of them to user (MVC5). When user clicks on report's name in the list he should see the report in pdf in new tab. On server side I get data contains binary data and length from db. The question is - how to open this data in new tab and not to download converted file on server or local machine?
You can achieve opening a pdf in new browser tab by using window.open and call your server side method in jquery something like this..
jQuery:
$('.reportName').click(function () {
window.open("../../ControllerName/ActionMethodName, '_blank');
});
Server Side:
public static void ActionMethodName()
{
///Here you got to convert your crystal report to memory stream inorder to pass stream array data inside binary write///
HttpContext.Current.Response.AppendHeader("content-disposition", "inline; filename=*****.pdf");
HttpContext.Current.Response.ContentType = "application/pdf";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Expires = -1;
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.BinaryWrite(outStream.ToArray());
}
I successfully created a form for User model where i can upload image with carrier wave. This works nicely with submit button.
Everything is fine but i want to improve that with jquery file upload or something similar. So my imagination is i will click on file_upload button then select the file and after that it will preview the thumb of image.
I tried to follow railcast #381 but when i upload image, the preview will appear after refresh of page. Is it better to use js response or json? Is there a better way for ajax image upload? Thanks for advices
See the Attached : Then use the following code.
Clicking on the "Upload different file" will trigger the hidden file uploader.
$('#page3-upload-bg-picture-link').click(function(){
$("#page3-upload-bg-picture").trigger("click");
});
Then if you upload a file, it will call the change funcution.
$("#page3-upload-bg-picture").change(function(){
page3BgImage(this);
});
Then the page3BgImage is going to be called. Here, the image is read from the location and show in my image's "You Uploaded Image" div.
function page3BgImage(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#page3-preview-bg-image').attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
I'm using EPiServer CMS 7.5 MVC application.
I can only see textboxes and buttons while creating a new form. I would like to have a link, which uploads a document, when clicked. Then this document should be able to view while looking to form data and also this should be attached along with the mail.
Any help?
There is no file upload control in XForm editor. One option - modify how XForm is rendered. XForm in EPiServer uses display templates to render. One way how to add file upload is to create your own XForm display template and add file upload. Display template will be used for all XForms in your application.
To create display template, create XForm.cshtml under /Views/Shared/DisplayTemplates/ in Visual Studio. Here is sample of source code of XForm.cshtml:
#using EPiServer.HtmlParsing
#using EPiServer.Web.Mvc.Html
#model EPiServer.XForms.XForm
#if (ViewData["XFormActionResult"] is EPiServer.Web.Mvc.XForms.XFormSuccessActionResult)
{
<strong>Form posted.</strong>
}
else
{
using (Html.BeginXForm(Model, new { #class = "form xform" }))
{
if (Model != null)
{
foreach (HtmlFragment fragment in (IEnumerable<HtmlFragment>)ViewData["XFormFragments"] ?? Model.CreateHtmlFragments())
{
// here can override particular fragment
// for example, check if TextBox Css class is "file-upload"
// then replace it with file upload
#Html.Fragment(fragment)
}
}
}
}
After that you have to handle posting the form yourself. This article describes well how to do it: http://www.eyecatch.no/blog/2013/01/using-xforms-and-mvc-in-an-episerver-7-block/
Then on OnActionExecuting in BasePageController you can handle file uploading. You can store it in the blob (in EPi 7 VPP) and store reference (GUID) in the XForm.
