I am unable to send view data to controller function In view their is select box with departmenr values from mysql database 我无法将视图数据发送到控制器功能在视图中它们是具有来自mysql数据库的离开值的选择框
<select class="select-dept" id="select-dept" name="select-dept">
<option>Select Department</option>
<?foreach ($departments as $dt):?>
<option value="<?=$dt['id']?>">
<?=$dt[ 'name']?>
</option>
<?endforeach;?>
</select>
i need to get refresh when user select department and that need to call controller function get_dept_employee And need to display datagrid of employee list 我需要刷新用户选择部门时需要调用控制器函数get_dept_employee并且需要显示员工列表的数据网格
you need to send data option as object 您需要将数据选项作为对象发送
try this 尝试这个
.....
url: "<?=base_url()?>.index.php/sms/get_dept_employee",
data: {"id":id},
dataType:"json",
....
and get the posted value as id
in your controller.. 并在控制器中将发布值作为
id
获取..
$id=$this->input->post('id');
....
var id = $("#select-dept").val();
data:"id", //Here you are sending string as id
should be 应该
data:id, //No double quotes surrounded
尝试:
data: {'id':$(this).val()},
i saw few errors 我看到几个错误
use data: {'id':id},
instead of data: "id",
使用
data: {'id':id},
而不是data: "id",
use dataType:"json",
instead of dataType="json",
使用
dataType:"json",
而不是dataType="json",
use cache:false
instead of cache: "false",

<script type="text/javascript">
