jQuery autocomplete mysql zend no response from action/controller?

Were using jquery autocomplete in zend and setup our action like this

public function ajaxautocompleteAction()
{
    $postData = $this->_request->getParams();
    $term = $postData['term'];
    $categoryObj = new Categories();
    $result = $categoryObj->searchCategory($term);
    $this->view->result = $result;
}

The javascript in the view file is this

    $(function() {
        var url = "http://www.domain.com/account/ajaxautocomplete?format=json";
开发者_如何学C        $( "#autotest" ).autocomplete({
            minLength: 2,
            source: function(request, response){
                var iterm = request.term;
                var url = "http://www.domain.com/account/ajaxautocomplete?format=json";
                $.post( url, {term: iterm},
                function( data ) {
            response(data); });
            }
    });
});

In chrome console i get this error

XMLHttpRequest cannot load http://www.domain.com/account/ajaxautocomplete?format=json. Origin http://domain.com is not allowed by Access-Control-Allow-Origin.

Any ideas why were not getting results from the ajax request?

This is how I've used jQueryUI's autocomplete and ZF before...

1. Create your action

   public function ajaxautocompleteAction()
   {
       $term = $this->getRequest()->getParam('term');
       $categoryObj = new Categories();
       $result = $categoryObj->searchCategory($term);
       $this->view->result = $result;
   }
   

2. Add an AjaxContext to your action, disabling automatic JSON serialisation. I'm skipping the auto serialisation as it's not common for your models to represent the usual "label" / "value" pairs jQueryUI's automcomplete looks for

   public function init()
   {
       $this->_helper->ajaxContext->addActionContext('ajaxautocomplete', 'json')
                                  ->setAutoJsonSerialization(false)
                                  ->initContext('json');
   }
   

3. Create your JSON view (views/scripts/account/ajaxautocomplete.json.phtml)

   <?php
   $data = array();
   foreach ($this->results as $category) {
       // format each result for jQueryUI autocomplete
       $data[] = array(
           'label' => $category->getName(),
           'value' => $category->getName()
       );            
   }
   echo Zend_Json::encode($data);
   

4. Add the URL for your autocomplete action as a JavaScript variable to the view that needs to use it (assuming you use the HeadScript helper in your layout)

   $this->headScript()->prependScript(sprintf('var searchUrl = "%s";',
       $this->url(array(
           'action'     => 'ajaxautocomplete',
           'controller' => 'account'
       ), null, true)));
   

5. Setup your JavaScript like this

   $("#autotest").autocomplete({
       source: searchUrl,
       minLength: 2
   });

looks like domain.com does not allow cross-domain calls.

Try chrome.exe --disable-web-security
