[eluser]Unknown[/eluser]
i have done the follwoing thing...........

Code:

$data = array('left_menu_list' => $query->result(),
       'header' => $this->data['company_name'],
       'footer' => $this->data['footer'],
       'version' => $this->data['version'],
       'powered_by' => $this->data['powered_by'],
       'list_of_pages' => $listpage,
       'base_url' => base_url(),
       'list_page_heirarchal' => $listpage_heirarchical,
       'hiren' => "index"    
);

so to use {header},{footer},{hiren},etc.... In if condition in client side...
for example

Client Side Code....
if({hiren}== "index")
{

}

is there any way to write like this in client side...????
