For semantics I'd use a <button> element like this:

<button class="link">Clicky</button>

to make the button look like normal text you can use CSS:

button.link { background:none; border:none; }

and for easiness of handing click I'd use jQuery like so:

$(".link").on("click", function(e) {

    // e is the event object

    // this is the button element

    // do stuff with them

});

Although if you have an ID attribute on the button you can use plain JS like this:

var button = document.getElementById("your-button-id");

button.addEventListener("click", function(e) {

    // e is the event object

    // e.target is the button element

    // do stuff with them

});
