jquery 和json返回的类型如何设置数组？
echo json_encode(array_values($rows));
或者：
$rows = array();
array_push($rows, array('value' = 'a', 'num' = 5));
array_push($rows, array('value' = 'b', 'num' = 1));
echo json_encode($rows);
如何用jquery将json 转数组
//数组转json串
var arr = [1,2,3, { a : 1 } ];
JSON.stringify( arr );
//json字符串转数组
var jsonStr = '[1,2,3,{"a":1}]';
JSON.parse( jsonStr );

jQuery处理json数据返回数组和输出的方法
这篇文章主要介绍了jQuery处理json数据返回数组和输出的方法,涉及jQuery操作数组及json的技巧,需要的朋友可以参考下
本文实例讲述了jQuery处理json数据返回数组和输出的方法。分享给大家供大家参考。具体实现方法如下：
代码如下:
the
json
object
*
*$("selector").print_r_json(json,opts)
:
return
formatted
string
(and
print)
*sprint_r_json
:
just
return
the
string;
*print_r_json
:
return
the
formatted
string
and
json
data
*contribute

*
*example:
*3
ways
to
use
it
*script
language="javascript"
*$("selector").print_r_json({"a":"aa","d":{"ef":{"a":"d","d":["a","b"]},"ed":"dd"},"g":"g"},{if_print:true,return_array:true});
*document.write($.sprint_r_json({"a":"aa","d":{"ef":{"a":"d","d":["a","b"]},"ed":"dd"},"g":"g"}));
*$.print_r_json({"a":"aa","d":{"ef":{"a":"d","d":["a","b"]},"ed":"dd"},"g":"g"});
*/script
