我正在使用最初为早期版本的 jquery 编写的代码，我认为我已经正确更新但没有显示...我需要它与 1.8.3 一起使用
我已经设置了一个小提琴，因为这样可以更容易地看到它的实际效果：fiddle
这是原始代码的来源：旅游代码
有任何想法吗？
这是jQuery：
$(function() {
/*
the json config obj.
name: the class given to the element where you want the tooltip to appear
bgcolor: the background color of the tooltip
color: the color of the tooltip text
text: the text inside the tooltip
time: if automatic tour, then this is the time in ms for this step
position: the position of the tip. Possible values are
TL top left
TR top right
BL bottom left
BR bottom right
LT left top
LB left bottom
RT right top
RB right bottom
T top
R right
B bottom
L left
