删除按钮在CodeIgniter中不起作用 [英] Delete button not working in CodeIgniter

问题描述

以下是我的删除按钮：

 < td& 
< a href =javascript：void（0）; onclick =delete（<？php echo $ data-> emp_id;？>）;> 
< button id =button_delete>删除< / button> 
< / a> 
< / td> 
  

这是我的Javascript代码：

 < script type =text / javascript> 
 var url =<？php echo base_url（）;？>; 
 function delete（id）
 {
 var r = confirm（您要删除此员工吗？ 
 if（r == true）
 {
 window.location = url +index.php / admin_logins / employee4 /+ id; 
} 
 else 
 {
 return false; 
} 
} 
< / script> 
  

这是我的控制器（ admin_logins.php ）方法 -

  function employee4（$ emp_id）
 {
 $ this-> employee_model-> delete_employee（$ emp_id）; 
 $ this-> index（）; 
} 
  

这里是我的模型（ employee_model.php ）method -

  public function delete_employee（$ emp_id）
 {
 $ this - > db-> where（'employee.emp_id'，$ emp_id）; 
 return $ this-> db-> delete（'employee'）; 
} 
  

我的表名为 employee

 列名数据类型
 id int 
 emp_id varchar（15） 
 emp_name varchar（50）
 emp_mobile_no varchar（15）
  

删除按钮，则不会发生任何操作。

解决方案

这是函数名 delete 测试它并给我这个错误：

未捕获的语法错误：意外的令牌delete

所以尝试用另一个名字命名，例如： deleteEntry 或 deleteEmployee / p>



delete 是javascript命令，因此是保留字，请避免使用保留字命名函数或变量

或者，我建议使用解决方案：

 < td& 
< a href =index.php / admin_logins / employee4 /<？php echo $ data-> emp_id;？> 
 onclick =return confirm（'您要删除此员工吗？'）;> 
< button id =button_delete>删除< / button> 
< / a> 
< / td> 
  

给 a 标记href，onclick返回确认讯息

Here's my Delete button:

<td>
    <a href="javascript:void(0);" onclick="delete(<?php echo $data->emp_id;?>);">
        <button id="button_delete">Delete</button>
    </a>
</td>

Here's my Javascript code:

<script type="text/javascript">
    var url="<?php echo base_url();?>";
    function delete(id)
    {
        var r=confirm("Do you want to delete this employee?");
        if (r==true)
        {
            window.location = url+"index.php/admin_logins/employee4/"+id;
        }
        else
        {
            return false;
        }
    }
</script>

Here's my controller (admin_logins.php) method -

function employee4($emp_id)
{
    $this->employee_model->delete_employee($emp_id);
    $this->index();
}

And here's my model(employee_model.php) method -

public function delete_employee($emp_id)
{
    $this->db->where('employee.emp_id',$emp_id);
    return $this->db->delete('employee');
}

My table name is employee and my database is MySQL.

Column Name         Datatype
   id                 int
  emp_id             varchar(15)
  emp_name           varchar(50)
  emp_mobile_no      varchar(15)

Whenever I click the Delete button, nothing happens. What am I doing wrong?

解决方案

It's the function name delete I tested it and gave me this error:

Uncaught SyntaxError: Unexpected token delete

So try to name it with another name, ex: deleteEntry or deleteEmployee

delete is the javascript command so it's reserved word, and please always avoid to name functions or variables with reserved words

Alternatively I suggest to use the solution:

<td>
    <a href="index.php/admin_logins/employee4/<?php echo $data->emp_id;?>" 
       onclick="return confirm('Do you want to delete this employee?');">
        <button id="button_delete">Delete</button>
    </a>
</td>

Give a tags href, and onclick just return confirmation message
