Optional course first, then choose the teacher
First choose course refers to the users listed in the drop-down list box, select the courses, and, these courses in the page load time should call interface to,
When the user use the drop-down list box selected a course, to be listed course corresponds to the teacher,
In other words, the teacher data acquisition, is needs to be done when the user selected courses, rather than when the page is loaded,
Drop-down list box, then, should according to course of action (select) binding function, the function call interface to the teacher in the list,
