The example in this article describes the method of jQuery processing json data to return array and output. Share it with everyone for your reference. The specific implementation method is as follows:

Copy code The code is as follows:

/*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
