getFieldValue for lookups

[Leonid]

I have a multi-value lookup field “Groups” set as a dropdown. Use of

getFieldValue("Groups")

results in a delimited string of Values. Is there a function to get IDs or key/value pairs?
I understand there is a people-picker syntax that does return a key/value pair for People Picker:

getFieldValue({"fin": xxx, "key": yyy})

Cant find yet what will work for a lookup field. Appreciate assist

Hi,
I’m not sure what you mean by “multi-value lookup field “Groups” set as a dropdown” – is this some kind of third party field type or is it the default lookup field with multiselect turned on so you have two lists side by side – one with unselected options and one with selected ones?

Right, Alex, just a regular Lookup field named “Groups”, with enabled multi-value selection.
The field is a lookup to another list. I’d like to pull not just selected values from the source list, but also selected items’ IDs.

getFieldValue("Groups")

only returns Values.
Wondering if there is a DFFS function to get value pairs or IDs.
I understand that if nothing else, I can run

spjs.utility.queryItems()

passing selected Values in CAML, but that seems too cumbersome just to get IDs.
Please advise.

You can use this function:

function getMultiLookupKeyValue(fin) {
    var a = [];
    jQuery("#dffs_" + fin + " select:last option").each(function (i, o) {
        a.push({ "id": o.getAttribute("value"), "title": o.innerText });
    });
    return a;
}
// Call it with the fieldinternalname
getMultiLookupKeyValue("LookupColumn2");

Thanks Alex, works like a charm! What exactly “#dffs_” does at run time? – back to DFFS API 🙂

[Alexander Bautz]

This is just a jQuery selector looking for the table row with ID = “dffs_FieldInternalName”. This ID attribute is inserted by the DFFS script and this is why it has the dffs_ prefix. This is not really a DFFS functionality, it’s just “traversing the DOM to find the element you are looking for” – you don’t need to use jQuery if you want to use plain javascript, but it’s most likely easier to use jQuery. You can read about the different jQuery methods here: https://api.jquery.com/category/traversing/
