Magento – Retrieve Values passed in Ajax Magento 1.9

admin-controlleradminhtmlajax

After making the ajax call, i try to recover the values, but returns null

this is function inside controller

    public function checkAction()
{
    # Retrieve value
    //$checkbox = Mage::app()->getRequest()->getPost('checkbox');
    //$checkbox = Mage::app()->getRequest()->getParam("checkbox");
    //$checkbox = $this->getRequest()->getParam("checkbox");
    $checkbox = $this->getRequest()->getPost("checkbox");

    Mage::log($checkbox);

    //response
    $response = array('namecheck' => $checkbox);

    # Send response Json
    $this->getResponse()->setHeader('Content-type', 'application/json');
    $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
}

this is ajax call

    new Ajax.Request('<?php echo $ajaxUrl; ?>', {
    method: 'POST',
    data: {
        ajax : true,
        checkbox : id_var,
        value : value_var,
        },
    onSuccess: function(transport) {
        alert('Sent notification.');
    },
    onFailure: function(transport) {
        alert("Couldn't send a notification. ");
    }
});

tips ?
I tried both getPost & getParams
and method: 'POST' & method: 'GET'

Log: null

Payload response: {"namecheck":null}

I solved this way, change data with params

var params = {id_check:id_checked, value_check:value_checked};
new Ajax.Request('<?php echo $ajaxUrl; ?>', {
    method: 'POST',
    cache : false,
    evalScripts: true,
    parameters:  params,
    onSuccess: function(transport) {
        alert('send');
    },
    onFailure: function(transport) {
        alert("Couldn't send a notification. ");
    }
});

and inside controller

    public function checkAction() {

    if($this->getRequest()->isXmlHttpRequest() && $this->getRequest()->isPost()){

        # Mage::log(print_r(Mage::app()->getRequest()->getParams(), true));

        $checkBoxId = Mage::app()->getRequest()->getParam('id_check');
        $checkValue = Mage::app()->getRequest()->getParam('value_check');

        # response
        $response = array( 'success' => 'success');

        # Send response Json
        $this->getResponse()->setHeader('Content-type', 'application/json');
        $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
    } else {
        //other
    }
}

Magento – AJAX Request JSON Response Always NULL

Try to edit your layout.xml for the ajax page:

<your_ajax_action>
        <reference name="root">
            <block type="yourajax/block" name="root" output="toHtml" />
        </reference>
</your_ajax_action>

This way, you will force the skipping of the headers, footers and other pages you don't need.

Alternatively you can try to simply echo your response and then exit() after. It is not the Magento way, but it usually works.

Looks like your admin route declaration is incorrect. Try this:

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <TwilitGrotto_AutoCustomerLookup after="Mage_Adminhtml">TwilitGrotto_AutoCustomerLookup</TwilitGrotto_AutoCustomerLookup>
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>
