Answer 1

As you are using jQuery create elements using it and also bind event using it. Here in example I have used .data() to store arbitrary value which can be fetched in the click handler

var a = $('<a>Click</a>')
        .data('parameter1', parameter1)
        .data('parameter2', parameter2)
        .on('click', function(){
            var parameter1 = $(this).data('parameter1');
            var parameter2 = $(this).data('parameter2');
            my_function(parameter1, parameter2)
        });

For immediate problem, you need to escape quotes properly

var a = '<a onclick="my_function(\''+ parameter1 + '\',\'' parameter2 + '\')">Click</a>';

As per comment parameter1 is a number you don't need to wrap it.

var a = '<a onclick="my_function('+ parameter1 + ',\'' parameter2 + '\')">Click</a>';

Why not:

var a = document.createElement('a');
a.innerHTML = "Click";
a.onclick = function(p1, p2) { ... your code here }
