乱码解决：

发生情况，项目的编码方式为gbk,页面的编码是gbk,使用ajax进行传值的过程中出现了乱码，解决的步骤如下，供参考。

页面获取值

var url="addPatternInfo.action";
var params={
	"patternInfo.Area_name":<strong><span style="color:#ff0000;">encodeURI(area_name)</span></strong>,"patternInfo.name1":encodeURI(name1)
};
$.ajax({
	async:false,type:"post",url:url,data:params,dataType:"json",<span style="color:#ff0000;"><strong>contentType:'application/x-www-form-unlencoded;charset=UTF-8',</strong></span>
	cache:false,success:function(data){
		alert("OK");
 	}
});

patternInfo.setName1(URLDecoder.decode(patternInfo.getName1(),"UTF-8"));
