If you mean a standard list view, you can use SP.ListOperation.Selection.getSelectedItems to get the id of the selected list item. Then you can retrieve the whole item (or a part of properties you need):

Here is an example:

var listGuid = SP.ListOperation.Selection.getSelectedList()
//in this example only first selected item is retrieved
var selectedItemId = SP.ListOperation.Selection.getSelectedItems()[0].id
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var lists = web.get_lists();
var list = lists.getById(listGuid);
var item = list.getItemById(selectedItemId);
ctx.load(item);
ctx.executeQueryAsync(function() {
    var title = item.get_item("Title");
    alert(title);
}, function(){alert("error");});
