原因是，返回或發送數據格式不規范.
當dataType指定為json后,1.4+以上的jquery版本對json格式要求更加嚴格.如果不是嚴格的json格式,就不能正常執行success回調函數.
JSON格式總結下
1）鍵名稱：用雙引號 括起
2）字符串：用使用雙引號 括起
3）數字，布爾類型不需要 使用雙引號 括起
養成好習慣
//ajax外 var data=“”； //ajax里 data：JSON.stringif(data)
Unrecognized token 'XXXX': was expecting ('true', 'false' or 'null')

為什么null == undefined為true，null === undefined false NaN == NaN false undefined == 0 false null == 0 false
"true"==true的結果為false,為什么？
BOOL與bool TRUE與true FALSE與false 區別
