[英]Multiple parameter passing in ajax call in MVC
我正在研究Codeigniter。 我的代码是:
这是我对下拉菜单更改事件的ajax方法调用(查看页面)
$('#drp').change(function(e){ //dropdown change event
var costcenter = $('#costcenter_id :selected').val(); //parameter 1
var location1 = $('#location_id :selected').val(); //parameter 2
var department = $('#department_id :selected').val(); //parameter 3
$.ajax({
cashe: false,
type: 'POST',
data: {'costcenterid':costcenter,
'locationid':location1,'departmentid':department},
url: 'http://local.desk.in/index.php/mycontroller/contollerfunction',
success: function(data)
{
alert("success");
}
});
});
这是我的控制器方法(控制器中的方法)
public function controllerfunction($costcenterid,$locationid,$departmentid)
{
echo "costcenter= ".$costcenterid;
echo "location= ".$locationid;
echo "department= ".$departmentid;
}
收到错误消息:
Message: Missing argument 1 for assetcontroller::controllerfunction(),
Message: Missing argument 2 for assetcontroller::controllerfunction(),
Message: Missing argument 3 for assetcontroller::controllerfunction()
为什么我无法将ajax参数值发送到控制器方法?
希望这个能对您有所帮助 :
由于您将ajax数据发布为post
因此必须在contollerfunction
方法中使用$this->input->post()
访问数据
您的控制器方法contollerfunction
应该是这样的:
public function contollerfunction()
{
$costcenterid = $this->input->post('costcenterid');
$locationid = $this->input->post('locationid');
$departmentid = $this->input->post('departmentid');
echo "costcenter= ".$costcenterid;
echo "location= ".$locationid;
echo "department= ".$departmentid;
exit;
}
