Example of processing AJAX requests in PHP development Framework Kohana _php Example

Today we share the AJAX request to process the page in Kohana. 2 steps. The premise is that your Kohana framework has been able to run correctly, notice.

1. The page makes a request.

Now the mainstream JavaScript framework is not jquery. jquery encapsulates Ajax requests, and here's how jquery is written. The demo is to get the back-end JSON string and use each to process it. The code is mostly from the JQAPI, accurate and convenient.

$.ajax ({
 URL: "/test/json",//test is controller, JSON is action, with/is relative to the site root directory
 Datatype:json,
//data: This is usually a spelling string, ' Id=1&name=jack ' this.
 Success:function (data) {
  var items = [];
  
 $.each (data, function (key, Val) {
  items.push (' <li id= ' + key + ' > ' + val + ' </li> ');
 });
  
 $ (' <ul/> ', {
  ' class ': ' My-new-list ',
  html:items.join (')
 }). Appendto (' body ');
 }
);

Processing in 2.kohana, returns the JSON string. Code on

Public Function Action_json ()
  {
    $this-> Auto_render = false;//does not need view
  
   if ($this-> request-> Is_aj AX ())//Determine if Ajax request
   {
     //get $arr here.
    echo Json_encode ($arr);//recommended to avoid 0 or other cases.
    Exit;
   
   }    
   JSON only supports UTF-8 encoding, this is important, remember!!!    
}

OK, I believe that after reading these 2 pieces of code, Kohana in the processing of AJAX requests, you must understand.

PS: The front desk js must be Utf-8 code, pay attention to Oh, pro.
