How do I grab values of clicked button?

[n3xtgen]

I am working on a web application and using the Google API for geo-location. I am using a localDB to store locations for now and displaying them using this:

function displayItems() {        
	readItems(LocalDB, function(items) {
		var appendHtml = "";
		
		for (var i = 0; i < items.length; i++) {			
			appendHtml += "<li><a id =" + items[i].locationId + " data-role='button'>Latitude: " + items[i].latitude + "<br/>" + "Longitude: " + items[i].longitude + "</a></li>";				
		}		

		if (items.length === 0) {
			appendHtml = "<li>No Locations Saved</li>";
		}
		
		$("#savedLocationList").empty();
		$("#savedLocationList").append(appendHtml);
		$("#savedLocationList").listview('refresh');
	});
}

Now when I click the button I want to grab the location(latitude, longitude) that corresponds to the link I clicked. How can I do this?

Thanks
