我正在开发一个动态网站,用户可以通过证明位置和专家来搜索医生,如下所示:
这是我的主页代码:
的index.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>AJAX</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<form>
<option value="0">-----select specialist-----</option>
<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("doctor_db",$con);
$q=$_GET["q"];
$sql="select * from specialty_tb where lid='".$q."'";
$res=mysql_query($sql);
while($ar=mysql_fetch_array($res)){
echo "<option value=".$ar[0].">".$ar[1]."</option>";
}
?>
</form>
</body>
</html>
getstate.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<form>
<option value="0">-----select doctor-----</option>
<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("doctor_db",$con);
$q=$_GET["q"];
$sql="select * from doctor_details where sid='".$q."'";
$res=mysql_query($sql);
while($ar=mysql_fetch_array($res)){
echo "<option value=".$ar[0].">".$ar[1]."</option>";
}
?>
</form>
</body>
</html>
getdis.php
$json = json_decode($row['orders'], true); // 2nd argument `true` converts json object into array.
$email = $json['email'];
这些是我的表
问题是,当我从列表中选择位置时,我可以使用位置ID从该位置获取专家。但我无法获得医生名单。
例如: - 如果我选择Kannur的位置,我会收到Kannur的所有专家,如表中所示,如果我选择一位专家,比如麻醉师,我无法获得医生名单,他们是麻醉师。根据在doctor_details中输入的数据,我应该根据所提供的sid在第三个列表中获得“医生1”。
有人可以帮帮我吗?

我认为你应该追加字符串然后通过javascript添加select
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<form>
<option value="0">-----select doctor-----</option>
<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("doctor_db",$con);
$q=$_GET["q"];
$sql="select * from doctor_details where sid='".$q."'";
$res=mysql_query($sql);
$option = '';
while($ar=mysql_fetch_array($res))
{
$option .= "<option value=".$ar[0].">".$ar[1]."</option>";
}
echo $option;
?>
</form>
</body>
</html>

这一行只有变化
<select id="ddlstate" name="ddlstate" class="form-control"
onchange="showHide(this.value)" >
您需要添加onchange事件,它才能正常工作。
答案 2 :(得分:0)
need to take another div tag in index.php:
<div id="ddlstate_div">
<select id="ddlstate" name="ddlstate" class="form-control">
/////
</select>
</div>
并更改ajax showHint函数:document.getElementById(“ddlstate”)。innerHTML替换为document.getElementById(“ddlstate_div”)。innerHTML
Add below tag in getstate.php:
<select id="ddlstate" name="ddlstate" onchange="showHide(this.value)" class="form-control">
</select>
