how to put a whole output of a view into a element of a JSON object?

My task is to save replay of user once submited and update the view, where we can see latest replay. for this i am using post method

$.post(url, dataString, function(data) {               
    if(data.error_message != '') $(".forum_replay").html(data.content); 
    // some thing
},"json");

In controller, i am saving data if there is no error.and then i wan开发者_开发百科t to update the view

$content = $this->load->view( $this->config->item('View_forum_replies') );
$json_data = array('error_message' => $message,
                   '$content'      => $content);
echo json_encode($json_data);

you have an error right here:

'$content'      => $content

you need to drop the $ from the first portion

you might also want to change

if(data.error_message != '')

to

if(data.error_message == '')
