    本文實(shí)例講述了jQuery處理json數(shù)據(jù)返回?cái)?shù)組和輸出的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：
    代碼如下:
    /*print 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 print json data
