今天用百度编辑器遇到很奇怪的问题，百度编辑器用var=UE.getEditor('editor').getPlainTxt()获取内容经过ajax传回后台给struts的action处理就编程乱码了，而其它一般的input标签的就没问题的，弄了很久得出以下的解决方法。

1：在js文件中给百度编辑器的内容进行转码

<span style="font-size:18px;"><h3>function addArticle() {
	/* 获取单选的值 */
	var category = document.getElementsByName("category");
	var value=0;
	for ( var i = 0; i < category.length; i++) {
		if (category[i].checked == true) {
			value = category[i].value;
			break;
		}
	}
   var title=document.getElementById("titleTopic").value;
	/* 获得百度编辑器的内容 */
	var ue = UE.getEditor('editor');
	var arr = [];
	arr.push(UE.getEditor('editor').getPlainTxt());
	alert(arr);
	//var content=encodeURI(encodeURI(arr));
	$.ajax({
		url : "article/addArticle.action" +'?categoryID=' + value,type : 'post',dataType : 'json',data : {
			"article.tiTle":title,"article.content":encodeURI(arr),},success : function(data) {
			if (data[0].result == 'success') {
				alert("成功发布博客");
				window.location.href = "/BlogToyo/pages/mainPage.jsp";
			} else {
				alert("发布失败，请刷新页面重试");
			}
		}
	});
}</h3></span>

2：在action后台则是解码

try {
content =URLDecoder.decode(article.getContent(),"utf-8");
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

<span style="font-size:18px;color:#FF0000;">3：tomcat的server.xml配置(采用UTF-8编码)</span>
<pre name="code" class="html"><span style="font-size:18px;">    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="UTF-8"</span>
<strong><span style="color:#FF0000;">			   /></span></strong>

<span style="font-size:18px;">	<!-- 指定web引用的默认编码集，相当于调用HttpServletRequest的setcharacterEncoding()方法 -->
	<constant name="struts.i18n.encoding" value="UTF-8" /></span>
