我有一个div,其中包含foreach,就像这样:
<div id="conversation">
<?php foreach($singles as $question): ?>
<div class="well well-sm">
<h4><?php echo $question['question_title']; ?></h4>
</div>
<div class="bubble bubble--alt">
<?php echo $question['question_text']; ?>
</div>
<?php endforeach; ?>
<?php foreach($information as $answer): ?>
<div class="bubble">
<?php echo $answer['answer_text']; ?>
</div>
<?php endforeach; ?>
</div>
我还有一个表格可以提供一个新答案:
<form method="post" style="padding-bottom:15px;" id="answerForm">
<input type="hidden" id="user_id" value="<?php echo $_SESSION['user_id']; ?>" name="user_id" />
<input type="hidden" id="question_id" value="<?php echo $_GET['id']; ?>" name="question_id" />
<div class="row">
<div class="col-lg-10">
<textarea class="form-control" name="answer" id="answer" placeholder="<?php if($_SESSION['loggedIn'] != 'true'): ?>You must be logged in to answer a question <?php else: ?>Place your answer here <?php endif; ?>" placeholder="Place your answer here" <?php if($_SESSION['loggedIn'] != 'true'): ?>disabled <?php endif; ?>></textarea>
</div>
<div class="col-lg-2">
<?php if($_SESSION['loggedIn'] != 'true'): ?>
<?php else: ?>
<input type="submit" value="Send" id="newAnswer" class="btn btn-primary btn-block" style="height:58px;" />
<?php endif; ?>
</div>
</div>
</form>
我通过ajax提交表单,并希望每次用户提交问题答案时,div #conversation
都会刷新并重新加载。现在我有以下ajax代码:
<script type="text/javascript">
$("#newAnswer").click(function() {
var answer = $("#answer").val();
if(answer == ''){
$.growl({ title: "Success!", message: "You must enter an answer before sending!" });
return false;
}
var user_id = $("input#user_id").val();
var question_id = $("input#question_id").val();
var dataString = 'answer='+ answer + '&user_id=' + user_id + '&question_id=' + question_id;
$.ajax({
type: "POST",
url: "config/accountActions.php?action=newanswer",
data: dataString,
success: function() {
$.growl({ title: "Success!", message: "Your answer was submitted successfully!" });
$("#answerForm").find("input[type=text], textarea").val("");
$("#conversation").hide().html(data).fadeIn('fast');
}
});
return false;
});
</script>
您会注意到我已经尝试$("#conversation").hide().html(data).fadeIn('fast');
,但它没有成功完成这项工作。它只将通过ajax传递的信息重新加载到div中,而不是仅重新加载foreach。
如何在ajax调用的成功函数中刷新div或<?php foreach(); ?>
?

success: function() {
$.growl({ title: "Success!", message: "Your answer was submitted successfully!" });
$("#answerForm").find("input[type=text], textarea").val("");
$("#conversation").hide().html(data).fadeIn('fast');
}
见表达式“.html(data)”???宣布“数据”在哪里?上面的代码永远不会起作用。现在,看看下面的行。特别是第一个。看到我的变化?
success: function(data) {
$.growl({ title: "Success!", message: "Your answer was submitted successfully!" });
$("#answerForm").find("input[type=text], textarea").val("");
$("#conversation").hide().html(data).fadeIn('fast');
}
进行此更改后,您需要使用调试器(chrome或其他)来检查从您的ajax调用(我们没有这里)返回的内容是您所需要的。但首先,修复错误。

jQuery .load()方法(http://api.jquery.com/load/)可以从网页获取和更新单个块。它将在后台重新加载整个网页,因此会产生一些开销..
将您的ajax成功更改为以下内容:
success: function() {
$.growl({ title: "Success!", message: "Your answer was submitted successfully!" });
$("#conversation").load("config/accountActions.php #conversation >*");
}
这应该加载你的会话块及其所有孩子并替换当前(旧)会话块。
