我正在通过 jQuery 进行 AJAX 调用，这会导致上述错误。奇怪的部分是代码在 LAMP、WAMP 上运行良好，但是当它被移植到真正的服务器时，它就会出现问题。
这是我的 AJAX 调用：
function wordAnalysis() {
$("#spinner").show();
removeTopics();
$.ajax({
type: "POST",
url: "{$site_root_path}pages/wordanalysis.php",
data: "statuses="+json_statuses,
success: function(msg){
$("#mainstage").html(msg);
$("#spinner").hide();
}
});
}
这是从 AJAX 调用加载的 Smarty .tpl 文件
<script type="text/javascript">{$words}</script>
<script type="text/javascript" src="{$site_root_path}extlib/jQCloud/jqcloud-1.0.0.min.js"></script>
<link rel="stylesheet" type="text/css" href="{$site_root_path}extlib/jQCloud/jqcloud.css" />
<script type="text/javascript">
$(document).ready(function() {
var max = {$max};
var avg = {$avg};
var time_taken = {$time_taken};
var count = {$count};
var size;

var word_list = [];
var table_height = $("#contentTable").height();

var ratio = table_height / orig_table_height;
var max_font_size = 45;
for (var word in words) {
if (words[word]['total'] < avg) {
continue;
}
color = Math.floor((words[word]['url']*100)/words[word]['total']);
size = Math.floor((words[word]['total']/max)*max_font_size);
size = Math.round(size*ratio);
var item = new Array();
item['text'] = word;
item['weight'] = words[word]['total'];
var html = new Array();
if (color <= 10) { html['style']= "color: #68a1ff;"; }

仅在真实服务器上而不是在 LAMP、WAMP 上出现这种错误的原因可能是什么？我基本上已经用chrome测试了它。
编辑：
调用后数据以 JSON 形式返回。
$words = StatusProcessing::findWords($statuses, $max, $avg);
$words = 'var words = '.json_encode($words);
$this->addToView('words', $words);
（这个 addToView 是一个基于 Smarty 的 assign 函数的函数。）
