Answer 1

you mean the attributes of the anchor tag when it is clicked?

first pass the reference of current element as this to the ga method

<a onclick="ga('send', 'event', 'View Seller Contact', 'Alfa Romeo', '147', this);" style="min-width: 123px;" data-id="161795" data-click="view-seller-contact" class="btn btn-primary-blue btn-xs " href="#">View Seller Contact</a>

now in the ga() method you can do

function ga( arg1, arg2, arg3, arg4, arg5, thisObj )
{
   $(thisObj).data('id')
   //rest of the code
}

Answer 2

If you want to access the data- attributes values of the link ( data-id="161795" and data-click="view-seller-contact" in your example), use the .data() method.

$('a').on('click', function(){
    var linkData = $(this).data();
});

The linkData variable will be an object - { id: 161795, click: "view-seller-contact" } . Use it how you want )
