How to add values to multiple lookup field in SharePoint using UpdateListItems

Question

I need to add multiple values (ID fields of another custom list) to a Multiple Lookup field using Sp-services.
What is the correct format of the data to be used ?
I have tried like ( 5,9,6 ) but only selecting the first item.

Answer 1

I have found a way to do it.

// "list1Id" contains the array of LIST1 ID fields that you want to add...
// "MULTIPLELOOKUPFIELD" is the multiple lookup field in the LIST2...

var multipleLookupValue ="";
for(i = 0; i < list1Id.length ; i++)
{
    multipleLookupValue = multipleLookupValue + list1Id[i]+";#data;#";
}

var method = "UpdateListItems";

$().SPServices({
    operation: method,
        async: false,  
        batchCmd: "New",
        listName: "LIST2" ,
        valuepairs: [["MULTIPLELOOKUPFIELD",multipleLookupValue]],
            completefunc: function (xData, Status) { 

                //alert("Added new item to LIST2 list");                                            
            }

});

May be it will help someone...
