Answer 1

One way you could do this by passing a value into your function. Let me make it clear by following example.

So there are two buttons

<button onclick="myFunction('edit')">Edit</button>
<button onclick="myFunction('save')">Save</button>

and Javascript function will look something like this

<script>
    function myFunction(event_type){
        if(event_type == 'edit'){
            //your further code for edit event goes here
        }
        else{
            //if event_type is not edit, then it's obviously save event
            //so your further code for save event goes here 
        }
    }
</script>
