推荐答案
（ document ).ready( function （）{
// 我们使用jQuery内置更改事件绑定onchange事件
(document).ready(function () { //We are binding onchange event using jQuery built-in change event
（' #ddlSubject'）。change（ functi on （）{
// 获取选定的值并检查是否选择了主题其他显示提醒框
var SelectedValue =
('#ddlSubject').change(function () { //get selected value and check if subject is selected else show alert box var SelectedValue =
（ #ddlSubject）。val（）;
if （SelectedValue> 0 ）{
// 获取所选文本并设置为标签
var SelectedText =
("#ddlSubject").val(); if (SelectedValue > 0) { //get selected text and set to label var SelectedText =
