我正在使用查询通过循环填充消息列表，这是我的代码：
<?php
$sql_i_msg_sent_waiting="SELECT t1.i_message_id,t2.username,t2.name,t2.propic,t2.age,t2.dob,t3.religion,t3.caste
FROM candidate_i_message as t1, candidate_register_table as t2, candidate_social_table as t3 WHERE t1.from_username='$_SESSION[logged_user]' AND t1.to_username=t2.username AND t2.username=t3.username AND t1.status='0'";
$result_i_msg_sent_waiting=mysql_query($sql_i_msg_sent_waiting,$con);
$count=mysql_num_rows($result_i_msg_sent_waiting);
echo $count;
?>
<div id="section_i_message_sent_waiting" style="width:650px; overflow:auto;">
<h2>Awaiting Sent Request</h2>
<?php
if(mysql_num_rows($result_i_msg_sent_waiting)==0)
{
?>

<input type="text" name="cancel_request[]" id="cancel_request[]"

creates a array of input type text, and each input text contains corressponding message_id...since each input text is contained within a form, and since the form is within a loop, the form is also repeatative..when the submit button will be clicked corressponding to a particular form, the input type text[] within that form will fire the value to get accepted in the javascript i give below...
<script>
function cancel_request(obj) {
alert(document.getElementByName('cancel_request[]').value);
}
</script>
但是脚本显示问题，它根本不起作用。我不知道怎么了。它没有显示任何东西。有 message_id 1 和 2：一个文本类型 input[] 包含值 1，另一个包含值 2。
当我单击对应于值 1 的提交按钮时，该文本类型输入的值将被发送到 JavaScript 并显示。我的脚本有什么问题？
