1)用户将在每个列表后单击按钮。 2)点击按钮将所选值发送到javascript函数 3)我想获取javascript函数中的值并使用ajax发送到php文件
问题如何使用onclick将html选定值发送到javascript函数?
<select id="list">
<option value=" ">Select a Name </option>
<option value="Comfy">Comfy</option>
<option value="Tough">William Tough </option>
<option value="Soft">Soft</option>
</select>
<button onclick="updateDB(this.querySelector('list'.selected))">Click Me</button>
<select id="list2">
<option value=" ">Select a Name </option>
<option value="Comfy">Comfy</option>
<option value="Tough">William Tough </option>
<option value="Soft">Soft</option>
</select>
<button onclick="updateDB(this.querySelector('list2'.selected))">Click Me</button>
Javascript功能:
function updateDB(number)
{
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {
// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","/updatequery.php?numbers",true);
xmlhttp.send();
}

检查OCI上的PHP文档:http://php.net/manual/en/function.oci-execute.php
执行select查询后,您需要从数据库中获取行。
此处的示例应该可以帮助您入门:
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
$stid = oci_parse($conn, 'SELECT * FROM employees');
oci_execute($stid);
echo "<table border='1'>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>\n";
foreach ($row as $item) {
echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";
}
echo "</tr>\n";
}
echo "</table>\n";
?>
