所以我的＆＃34; type1＆＃34; select语句将选择一个问题类别，然后根据该问题，我想要一个在另一个下拉列表中处理该问题的员工的下拉列表。另外，如何使所有隐藏的select语句占用相同的空间？
这是我的代码：
<!DOCTYPE html>
<html>
<head>
<title>IssueReport</title>
<script src = "../../jquery.js"></script>
<style>
body{
padding:0;
margin:0;
}
#box {
padding: 5px;
color:black;
margin: 0 auto;
border-style: solid;
border-color: #0000E6;
border-width: 2px;
background-color: #58C6EB;
width: 162px;
height: 687px;
float: left;
border-radius: 10px;
}
.word{
color: #0000E6;
}
.buttons{
background-color: #CCFFFF;
border-radius: 5px;
}
</style>
<script>
function showForm(){
var issue = document.getElementById("type1").value;
if(issue == 'Program Glitch'){
document.getElementById("IT1").style.display = "block";
}
$("#type1").onchange(function{
});
}
$(document).ready(function(){
$("#sub").click(function(){
var user_issue = $("#issue").val();
var user_priority = $("#priority").val();
var user_type = $("#type1").val();
var user_author = $("#author").val();
$.post("BugReport.php",{issue:user_issue,priority:user_priority,type1:user_type,author:user_author},function(data){
$("#result").html(data);
});
});
$("#sub").click(function(){
document.getElementById('issue').value='';
$('#type1').prop('selectedIndex', 0);
$('#priority').prop('selectedIndex', 1);
});
});
</script>
</head>
