Sharepoint : Get list item Attachment by Name using JSOM

Scenario : Suppose you want to get the attachment from a list item and you only know its name .



Solution :You can achieve this using a simple JSOM code as shown below . the major player in this code is the line "splistItem.get_attachmentFiles().getByFileName("FILENAME"));"




function getAttachmentsDetails()
{

var clientContext = SP.ClientContext.get_current();

var splist = clientContext.get_web().get_lists().getByTitle("LISTNAME");

var splistItem = splist.getItemById(ID);

clientContext.load(splistItem);

// gets the item by attachment file name

clientContext.load(splistItem.get_attachmentFiles().getByFileName("FILENAME"));

clientContext.executeQueryAsync(Function.createDelegate(this, Success), Function.createDelegate(this, Fail));

 

function Success(sender, args) {

    var attachitem = splistItem;

    var total = attachitem.get_attachmentFiles().get_count();

    if (total > 0) {

        console.log(total + " file attachments"); // count will give the attachment count

    }      

}

 

function Fail(sender, args) {

    //failed function

}

}

That's All! SharePoint All the Way !!!
