Open SharePoint PDF documents in modal dialog

November 13, 2017 / Kannan / 0 Comments

Sometimes we need PDF documents to be opened in dialogs instead of SharePoint’s default behavior which is opening the document in the same window or tab.

The following code helps in implementing this.

Note: This code only works for PDF documents. For office documents look at the next article.

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<script type="text/javascript">
    $("a[href$='.pdf']").each(function() {
        $(this).removeAttr("onclick").attr("href", "javascript:OpenDocumentInDialogue(\"" + this.href + "\")");
    });

    function OpenDocumentInDialogue(href) {
        var o;
        $("body").append("<div id='docTemp' style='min-height:600px;min-width:800px;height:100%;overflow:hidden'><object data='" + href + "' width='100%' height='100%' type='application/pdf' ></object></div>");
        o = {};
        o.html = $("#docTemp")[0];
        o.showMaximized = true;
        o.title = href.substring(href.lastIndexOf("/") + 1);
        o.dialogReturnValueCallback = OpenDocumentInDialogueCallback;
        SP.UI.ModalDialog.showModalDialog(o);
    }

    function OpenDocumentInDialogueCallback() {
        // Do something here when the dialog closes
    }
</script>
