我正在做一个大项目。我正在制作评论回复系统。它适用于Ajax，但当我发布第二个或另一个评论回复时，文本区域显示为空。为什么只有第一个回复成功提交？这是我的代码：
$(document).ready(function(){
$(".post_reply").click(function(rp) {
rp.preventDefault();
var box_id = $(".bid").val();
var ownerc = $(".owner").val();
var replyc = $(".reply").val();
var commentc_id = $(".comment_id").val();
var dataString = 'bid='+ box_id + '&owner=' + ownerc + '&comment_id=' + commentc_id + '&reply=' + replyc;
alert(replyc);
if(ownerc=='' || box_id=='')
{
alert('Please Give Valide Details');
}
else
{
$.ajax({
type: "POST",
url: "sub_comment.php",
data: dataString,
cache: false,
success: function(replys){
$('#replys'+commentc_id).append(replys);
$(".reply").val('');
}
});
}
return false;
});
});
这里是评论系统的整个代码..
<h3>User Comment</h3>
<div class="comments_area">
<?php
$comments=mysql_query('select * from comments where bid="'.$_GET['id'].'"');
while($get_info=mysql_fetch_array($comments)){

$cuid=$get_info['uid'];
$c_users=mysql_query('select user_name,thumb from users where id="'.$cuid.'"');
$get_uinfo=mysql_fetch_array($c_users);
$cname=$get_uinfo['user_name'];
$cimage=$get_uinfo['thumb'];

include_once 'config.php';
if(isset($_POST['reply'])){

$get_user=mysql_query('select * from users where id ="'.$uid.'"');
$replyr=mysql_fetch_array($get_user);
$rname=$replyr['user_name'];
$rimage=$replyr['thumb'];
if(strpos($rimage,'https://') !== false) {
$rthmbs=$rimage;
}else
{
$rthmbs='images/thumbs/'.$rimage;
}
$like_type='replyed';
mysql_query('insert into replys(reply,comment_id,bid,uid)values("'.$reply.'","'.$comment_id.'","'.$bid.'","'.$uid.'")');

答案 0 :(得分：0)
return false;似乎导致问题。
return false;在调用时做三件事：
因此，如果您return false;，点击事件将永远不会再次触发。只需使用preventDefault（）。
