如何通过jquery打印ajax数据

Question

url：“index.php / post / get_post”，此url返回json数据，如...

[{"id":"3","user_id":"2","message":"okiokiokio","is_active":"1","created_at":"2013-05-24 00:00:00","updated_at":"2013-05-24 00:00:00"}]

如何在特定字段中打印数据

$(document).ready(function(){
        $.ajax({
                type: "POST",
                url: "<?php echo base_url();?>index.php/post/get_post",
                datatype: 'json',
                success: function(data){
                    $('#divusername').append(data.user_id);       
                }
        });
});

Answer 1

您需要使用

 $('#divusername').append(data[0].user_id);

Answer 2

这可能会对你有帮助。

$(function() {
    $.ajax({ type: "POST", url: "index.php/post/get_post",
        datatype: 'json',
        success: function(data){
            var parsed_data = $.parseJSON(data);
            $('#divusername').html(parsed_data.user_id);
        }
    });
});
