CodeIgniter框架的$this->input->post()获取ajax传到后台的参数为什么是一推包含标签的东西
前端：
$.ajax({

            url: "admin.php?d=morketing&c=activity&m=updateAct",
            type: "POST",
            dataType: 'json',
            // data:  $('form.form-horizontal').serialize(),
            data:  parameter,
            success: function(data) {
      });

后台：
$data = $this->input->post();
var_dump($data);
<pre class='xdebug-var-dump' dir='ltr'>

Answer 1

你先打印你的parameter，然后传json格式数据，后台$data = $this->input->post("data");
