嗨,我有这个代码来解析JQUERY上的JSON
var json_text2 = $.parseJSON('{"data":[["1340650436","2.00000"],["1340736844","4.00000"]],"label":"Waist Size (cm)"},{"data":[["1340736861","3.40000"],["1340650514","4.00000"]],"label":"Arm Size (Inch)","yaxis":"2"}');
但是我在Firebug上遇到了这个错误
JSON.parse: unexpected non-whitespace character after JSON data
php在我的socialengine目录中.我应该如何获得用户的user_id谁登录？你能给我一个确切的例子吗？
