JS Code To Copy Folders And Files From One Library To Another On The Same SubSite

Question

Trying to find a way to copy folders(with documents inside) and files from a SharePoint Online Library to another, need to preserve the metadata of the files as well. The new modernized experience on SharePoint has a built in feature to do that, but I have a classic experience site that has that feature restricted, so need to find a way to do it there, ideally triggered from a button in the ribbon. Any help will be very much appreciated!

Answer 1

Found a solution for selected multiple files in a library to be copied to another library in the same sub-site, here is the tested and working code, it is for selected files only, the syntax for folders will be similar, the SP.MoveCopyUtil.copyFile will become SP.MoveCopyUtil.copyFolder:

<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script>
<input type="button"  value="Copy Files" style="cursor:pointer;" onclick="copyFiles()" />
<script type="text/javascript">
    function copyFiles() 
    {
        var context = SP.ClientContext.get_current();
        var selectedItemIds = SP.ListOperation.Selection.getSelectedItems(context); 


        var output = "Destination Library";

        for (idx in selectedItemIds)
        {
            SP.MoveCopyUtil.copyFile(context, $("#" + selectedItemIds[idx].id + " a")[0].href.toString(), output + $("#" + selectedItemIds[idx].id + " a")[0].href.split("/")[$("#" + selectedItemIds[idx].id + " a")[0].href.split("/").length - 1].toString(), true );
        }

        context.executeQueryAsync(function(){alert("OK")}, function(){alert("NOT OK")});
    }
</script>

After update 2

I tested it in my SPO and its working correctly.

Assumptions:

1. List view webpart
2. File name is present in the list view webpart

<script>
    function copyFiles() {
        var current_context = SP.ClientContext.get_current();
        var web = current_context.get_web();
        var selectedItems = SP.ListOperation.Selection.getSelectedItems();
        for (var i = 0; i < selectedItems.length; i++) {
            var id = selectedItems[i].id;
            debugger;
            var element = document.getElementById(id).children[0];
            var filePath = "";
            var fileName = "";
            if (element) {
                debugger;
                filePath = element.href;
                fileName = element.href.split('/').pop();
                var output = "https://mySiteUrl.sharepoint.com/DocumentLibrary/" + fileName;
                SP.MoveCopyUtil.copyFile(current_context, filePath, output, true);
                current_context.executeQueryAsync(function () { 
                    PageCopySuccess(); }, function () { PageCopyFailure();
                     });
                function PageCopySuccess() {
                    alert('Success');
                }
                function PageCopyFailure() {
                    debugger;
                    console.log(arguments);
                    alert('Failed');
                }
            }
        }
    }

</script>
<input type="button" value="Copy Files" style="cursor:pointer;" onclick="copyFiles()" />
