Ext.urlEncode与Ext.urlDecode：
用于js对象和查询字符串之间的相互转换
Ext.urlEncode例子如下：
/*
Ext.urlEncode( object, [recursive] )
将一个js对象编码为查询字符串
*/
Ext.urlEncode({birth:{year:1991,month:05,day:07}},true); Ext.urlEncode({colors:['red','green','blue']});//可以加上true Ext.urlEncode({hobbies:['coding','eating','sleeping',['nested','stuff']]},true);
Ext.urlDecode例子如下：
/*
urlDecode( queryString, [recursive] )
将一个查询字符串解码为js对象
*/
//第二个递归参数：主要用于解决对象和数组的解码问题
Ext.urlDecode('birth[year]=1991&birth[month]=05&birth[day]=07') Ext.urlDecode('hobbies[0]=reading&hobbies[1]=write&hobbies[2]=coding') Ext.urlDecode('hobbies[0]=coding&hobbies[1]=eating&hobbies[2]=sleeping&hobbies[3][0]=gaming&hobbies[3][1]=traveling') Ext.urlDecode('birth[year]=1991&birth[month]=05&birth[day]=07',true) Ext.urlDecode('hobbies[0]=reading&hobbies[1]=write&hobbies[2]=coding',true) Ext.urlDecode('hobbies[0]=coding&hobbies[1]=eating&hobbies[2]=sleeping&hobbies[3][0]=gaming&hobbies[3][1]=traveling',true)
