从CodeIgniter控制器执行Java脚本代码

Question

In my CodeIgniter controller every Ajax request checks the token I Passed. If any thing happens wrong I wrote a controller function to destroy all session and logout

 'redirect('main/logincontent/load_logout');'

In load_logout function

function load_logout() {

echo "<script>var c=confirm('do you want to continue?');
 if(c==true)
      {

      }
      else
     {</script>";
      $this -> session -> sess_destroy();
     echo "<script>window.parent.location.href ='" . base_url() . "';
     }</script>";
  }

I tried put a confirm box at the beginning of the function load_logout() . Based on confirm box result user can decide whether to destroy session and logout or stay Online .

But it is not working!!!

Any help would be appreciated.

you don't need to close script tag each time, try this

  echo "<script>var c=confirm('do you want to continue?');
  if(c==true){}else{";
  $this -> session -> sess_destroy();
  echo "window.parent.location.href ='" . base_url() . "';
  }</script>";

but it is impossible to destroy session from client side. What you are doing here is just printing these details in client browser. But $this -> session -> sess_destroy(); will not work in browser, because it is server code. You need to add a route to destroy session and call that.
