在ubinder (adbrite script)中转义&号

escaping ampersands in UIBinder (adbrite script)

本文关键字：转义 script ubinder adbrite      更新时间：2023-09-26

我需要将以下脚本集成到UIBinder的div中:

 <!-- Begin: adBrite, Generated: 2011-04-14 8:40:27  -->
 <script type="text/javascript">
 var AdBrite_Title_Color = '66B5FF';
 var AdBrite_Text_Color = '000000';
 var AdBrite_Background_Color = 'FFFFFF';
 var AdBrite_Border_Color = 'CCCCCC';
 var AdBrite_URL_Color = '008000';
 try{var AdBrite_Iframe=window.top!=window.self?2:1;var AdBrite_Referrer=document.referrer==''?document.location:document.referrer;AdBrite_Referrer=encodeURIComponent(AdBrite_Referrer);}catch(e){var AdBrite_Iframe='';var AdBrite_Referrer='';}
 </script>
 <span style="white-space:nowrap;"><script type="text/javascript">document.write(String.fromCharCode(60,83,67,82,73,80,84));document.write(' src="http://ads.adbrite.com/mb/text_group.php?sid=123&zs=123&ifr='+AdBrite_Iframe+'&ref='+AdBrite_Referrer+'" type="text/javascript">');document.write(String.fromCharCode(60,47,83,67,82,73,80,84,62));</script>
 <a target="_top" href="http://www.adbrite.com/mb/commerce/purchase_form.php?opid=123&afsid=1"><img src="http://files.adbrite.com/mb/images/adbrite-your-ad-here-leaderboard.gif" style="background-color:#CCCCCC;border:none;padding:0;margin:0;" alt="Your Ad Here" width="14" height="90" border="0" /></a></span>
 <!-- End: adBrite -->

GWT编译器抱怨与符号，所以我将它们更改为&amp;。

我还小心地在文件的顶部声明了以下内容，以便能够正确解析&实体:

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">

这至少允许我编译代码，但结果页面呈现&amp;而不是&，这当然破坏了脚本。

如何正确转义&号以使脚本正常运行?是否有一种方法来声明这个脚本在我的加载器html/jsp，并有它呈现成我选择的一个div ?我在Adbrite的网站上找不到太多的文档。

最后，Adbrite真的有必要试图隐藏脚本来自远程站点的String.fromCharCode胡说八道的事实吗?据推测，这样做是为了防止某种XSS过滤。

谢谢

将Javascript代码放在HTML注释之间。将&替换为&amp;

下面是修改后的代码:

            var AdBrite_Border_Color = 'CCCCCC';
            var AdBrite_URL_Color = '008000';
            try{var AdBrite_Iframe=window.top!=window.self?2:1;var
