How to make a select field show list of options? - Javascript/jQuery

Question

I'm trying to mimic focus on a select field.

eg When a user gains focus on a select field, the select field shows the options in a drop down list.

When using $('select').focus() , the options are not shown.

Any help on this one guys? =)

在焦点上将select的size属性设置为6（或者您喜欢的任何小int），并在blur上将其设置为0。
