• image_tag: function to display the image
• :action: method inside the controller
• :with: parameters sent to action
• :complete: JavaScript function that will be called when the AJAX call is over
• :update: html object when the content of the return method (:action) will be stored. My “jstemp” is just a div tag like this:

Controller Action

render :text =>  
"{\"checkout\": { \"zipprice\": \"\", \"checkouttotalvalue\": \"#{str_valor_total.real_formatado}\"}}"

HTML / Javascript

function updateZipAndPrice() {
 var myJSONtext = $('jstemp').innerHTML;
 var myJSONObject = eval('(' + myJSONtext + ')');
 $('freteValue').innerHTML = myJSONObject.checkout.zipprice;
 $('checkoutValue').innerHTML = myJSONObject.checkout.checkouttotalvalue;
}
