Answer 1

轻松修复。

这一行只是缺少一个支架

data: {pro:  val, staff_id: $('#staff_id').val()} <---  ,

Answer 2

您缺少}数据：

这是解决方案代码 -

function changeProgram(val){
    $.ajax({
        type: "POST",
        url: "getSemester?pro=NULL",
        data: {pro:  val, staff_id: $('#staff_id').val()},
        success: function(data) {

            var new_data = $.parseJSON(data);
            if(new_data.length>0 ){
                var dom ="<option value=''>SELECT</option>";

                for(var index = 0; index < new_data.length; index++) {
                    dom += "<option value='"+new_data[index].SM_SEMESTER_CODE+"'>"+new_data[index].STOTAL+" - "+new_data[index].SM_SEMESTER_DESC+"</option>";

                }
                $(".semesterGroup").html(dom);

            }else{
                var dom ="<option value=''>SELECT</option>";
                $(".semesterGroup").html(dom);
            }
        }
    });
}
