尝试使用 jquery 仅 ajax $the_message 字段以避免浏览器刷新的表单出现问题
我想避免浏览器刷新并只显示消息而不刷新浏览器。
$idc = $_GET['id'];
$name1 = $_GET['name'];
$id2 = $_GET['ids'];
if ($_POST['message_field'] != ""){
$message_field = $_POST['message_field'];
$sql = mysql_query("INSERT INTO comment (mem_id,commented_men_id, message, message_date)
VALUES('$userid','$idc','$message_field', now())")
or die (mysql_error());
}
$sql_message = mysql_query("SELECT id, mem_id ,message, message_date FROM comment WHERE mem_id='$userid' ORDER BY message_date DESC");
while($row = mysql_fetch_array($sql_message)){
$id = $row["id"];
$me_id = $row["mem_id"];
$json = $row["message"];
$message_date = $row["message_date"];
$message = json_encode($json);
$sql_mem_data = mysql_query("SELECT id, name FROM users WHERE id='$me_id'");
while($row2 = mysql_fetch_array($sql_mem_data)){
$id = $row2["id"];
$ufirstname = $row2["name"];
}
$messageList .= '<div id="only"><p>' . ufirstname . '</p><br/><p id="pmessage">'.$the_message.'</p></div>';
}

表结构
CREATE TABLE IF NOT EXISTS `blabbing` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`mem_id` int(11) NOT NULL,
`commented_men_id` int(11) NOT NULL,
`the_message` varchar(255) NOT NULL,
`sub_commented_id` int(11) NOT NULL,
`message_date` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`type` varchar(50) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=146 ;
I want to avoid the browser refresh and get to display only the message without the browser refresh.
$idc = $_GET['id'];
$name1 = $_GET['name'];
$id2 = $_GET['ids'];
if ($_POST['message_field'] != ""){
$message_field = $_POST['message_field'];
$sql = mysql_query("INSERT INTO comment (mem_id,commented_men_id, message, message_date)
VALUES('$userid','$idc','$message_field', now())")
or die (mysql_error());
}
$sql_message = mysql_query("SELECT id, mem_id ,message, message_date FROM comment WHERE mem_id='$userid' ORDER BY message_date DESC");
while($row = mysql_fetch_array($sql_message)){
$id = $row["id"];
$me_id = $row["mem_id"];
$json = $row["message"];
$message_date = $row["message_date"];
$message = json_encode($json);
$sql_mem_data = mysql_query("SELECT id, name FROM users WHERE id='$me_id'");
while($row2 = mysql_fetch_array($sql_mem_data)){

$ufirstname = $row2["name"];
}

您需要阻止默认提交操作才能执行此操作,您可以使用
preventDefault
。另外请结束脚本标签
You need to prevent default submit action to do that you can use
preventDefault
.Also please end the script tag
