伊万加利肯·斯科尔：：Aees历史
函数showUser（str，aa）
{
如果（str==“”）
{
document.getElementById（“txtHint”）.innerHTML=“”；
回来
}
if（window.XMLHttpRequest）
{//IE7+、Firefox、Chrome、Opera、Safari的代码
xmlhttp=新的XMLHttpRequest（）；
}
其他的
{//IE6、IE5的代码
xmlhttp=新的ActiveXObject（“Microsoft.xmlhttp”）；
}
xmlhttp.onreadystatechange=函数（）
{
if（xmlhttp.readyState==4&&xmlhttp.status==200）
{
document.getElementById（“txtHint”）.innerHTML=xmlhttp.responseText；
}
}
open（“GET”、“getuser.php？q=“+str+”&aa=“+aa，true”）；
xmlhttp.send（）；
}
课程信息将列在这里。
<?php
include("_gradeviewr.php");
require_once ("include/config.php");
require_once ("include/Connection.php");
require_once("include/functions.php");
error_reporting(E_ERROR | E_PARSE);
ob_start();
$q = $_GET['q'];
$aa=$_GET['aa'];
$con = mysqli_connect('localhost','root','','evang_www');
if (!$con)
{

}
mysqli_select_db($con,"evang_www");
$sql="SELECT * FROM uploaded WHERE sbid='".$aa."' AND subject = '".$q."'" ;
$result = mysqli_query($con,$sql);
echo "<table border='1'>

while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['subject'] . "</td>";
echo "<td>" . $row['datefrom'] . "</td>";
echo "<td>" . $row['dateto'] . "</td>";

因此，我想将id传递给getuser.php。因为您已经在使用jQuery，所以请尝试$.get 示例代码（将此代码放在页面底部）
函数showUser（str，aa）
{
如果（str！=''）
{
$.get（'getuser.php'，{q:str，aa:aa}，函数（数据）{
$（'#txtHint'）.html（数据）；//通过数据处理结果
});
}
}
<script>
function showUser(str,aa)
{
if(str != '')
{
$.get('getuser.php',{q:str,aa:aa},function (data) {
$('#txtHint').html(data); // handle the result via data
});
}
}
</script>
