我可以看到问题，但不是什么导致它。我想你正在通过PHP输出一些javascript，但它会在<html>标签之上出现。
如果您转到视图出处：http：//www.YOURDOMAIN.be/new/index.php页= &行动=喊
的HTML如下：
<script>
$(document).ready(function(){noty({"text":"Uw shout is succesvol toegevoegd.",
"layout":"top","type":"success","animateOpen":{"height":"toggle"},
"animateClose":{"height":"toggle"},"speed":500,"timeout":5000,
"closeButton":true,"closeOnSelfClick":true,"closeOnSelfOver":false,"modal":false});});</script><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
