Question

how to get Multiple lines of text values from a document library in sharepoint 2013 using client object model

I tried this code to get value :

        docEnumerator = collVideoLibrary.getEnumerator();
        //Looping through the collection
        while (docEnumerator.moveNext()) {
            docItem = docEnumerator.get_current();
            var description = docItem.get_item('Description');

but I didn't get the Description form document library

please do needful.

Answer 1

Use Description0 as column's internal name because SharePoint Document Library already contains a column named as Description and if you try to create another custom column whose DisplayName is Description then its InternalName would be Description0
