问题描述
您好，我正在使用MVC 5，当我从第一页移动时，根据按钮点击第二页，我根据从第一页收到的ID提交下拉列表和问题清单。但现在我想根据我从下拉列表中选择的部门列出那些问题列表。有人可以帮我这个吗？
我尝试过：
< script>
$（document）.ready（function（）{
$（＃DropdownDivisionList）。change（function（）{
var a = $（＃DropdownDivisionList Option：Selected） .text（）;
$（'＃span2'）。text（a）;
}）
}）
< / script>
< script type =text / javascript>
$（document）.ready（function（）{
$（＃DropdownDivisionList）。change（function（）{
var division = $（this）.val（）;
$ .getJSON（../ Home / GetIssueListByDivision，{division：division}，
function（data）{
var select = $（＃span2）;
select.empty（）;
select.append（$（'< option />'））;
$ .each（data，function（index，itemData）{
select。 append（$（'< option />'，{
value：itemData.Value，
text：itemData.Text
}））;
}）;
}）;
}）;
}）;
< / script>
