　　不用整天为美化select控件烦恼了。

　　1、可批量美化select控件。

　　2、可以有onchange句柄。

　　3、触发onchange的函数可带参数。

　　3、可以得到select的值。

　　4、可设置像select类似的滚动条(如大于或等于8个数目时出现滚动条)

　　5、可设置宽度和高度

　　API参考：

　　//首先生成一个simulateSelect的实例

　　//构造函数的第一个可选参数为触发onchange的函数，其它的为onchange函数的参数;

　　c = new simulateSelect(s1onchange, "never-online");

　　//设置select的CSS，第一个参数为控件的主要CSS、第二个为选中条目时的CSS、第三个为没有选中条目时的CSS

　　c.style("CtlSelect2", "selected2", "unselected2");

　　//设置select的宽度和高度;

　　c.width = 320;

　　c.height = 20;

　　//初始化参数为：select控件的ID，可以用逗号分离，进行批量转换;

　　c.init("s1,s2,s3");

　　下一版本将可修改combox
