I need to Open/Download Word or PowerPoint Document directly from Provider Hosted SharePoint App. We can perform easily in on-premise using editDocumentWithProgID2

Tried with getting CORE.js, SP.js and other related js files from 15 hive and placed in solution with referencing inside the aspx page.

<script src="../Scripts/js/SP.Init.js"></script>
<script src="../Scripts/js/SP.Core.js"></script>
<script src="../Scripts/js/SP.Runtime.js"></script>
<script src="../Scripts/js/SP.js"></script>    
<script src="../Scripts/js/CORE.JS"></script>    

This below function is called on anchor tag in javascript.

function EditDocumentFile(filename) {                        
        editDocumentWithProgID2(filename, '', 'SharePoint.OpenDocuments', '0', '/', '0');

function editDocumentWithProgID2(strDocument, varProgID, varEditor, bCheckout, strhttpRoot, strCheckouttolocal) {            

        var sURL = unescape(window.location.pathname);
        window.location.href = sURL;           

        var errorCode = editDocumentWithProgIDNoUI(strDocument, varProgID, varEditor, bCheckout, strhttpRoot, strCheckouttolocal);            

        if (errorCode == 1) {
            window.onfocus = RefreshOnNextFocus;
        else if (errorCode == 2)

Not working and shows error:

Uncaught ReferenceError: unescapeProperly is not defined

in browser developer tool console.

Any idea how to work with editDocumentWithProgID2 in CSOM ?

  • Can you check this out stackoverflow.com/a/1842937/1294606 – Atish Dipongkor - MVP Nov 5 '15 at 6:41
  • Thanx Atish, Yes I already have done this way. The reference which you gave would work only for on-premise. Let me edit my question again. – Kb15 Nov 5 '15 at 12:06
  • is your requirement only to open/download document whenever users will click on the link? if so, then I have a alternative solution for you – Atish Dipongkor - MVP Nov 5 '15 at 12:50
  • yes exactly.... – Kb15 Nov 5 '15 at 12:53
  • Do you have document URL already? – Atish Dipongkor - MVP Nov 5 '15 at 13:00

Based on the comment, I am writing an alternative solution.

Add ?web=1 or ?web=0 for open or download your document.

  • web=0 means file will be downloaded when you hit this URL in browser.
  • web=1 means file will be opened in browser using office online.


Let's say your document URL is serverurl/Local Library/SharePoint 2013 Installation Guide.docx, Now create the <a> like following for opening this document

<a href="serverurl/Local Library/SharePoint 2013 Installation Guide.docx?web=1">file Name</a>

For downloading

<a href="serverurl/Local Library/SharePoint 2013 Installation Guide.docx?web=0">file Name</a>
