Magento后台编辑页面加AJAX

如 /app/code/local/Xinson/News/controllers/Adminhtml/NewsController.php 的 editAction() 方法

$this->renderLayout() 之前加

$this->_addContent($this->getLayout()->createBlock('core/text')->setText("
<script>
    document.getElementById('placeholder_limit').onblur = function(){
        var url = 'http://test.shop.com/serial-codes/';
        new Ajax.Request(url, {
            method: 'post',
            onSuccess: function(text) {
                //yourtext = text.responseText.evalJSON(true);
                document.getElementById('placeholder_limit').parentNode.innerHTML += '<span><img src=http://test.shop.com/media/wysiwyg/sdk/categories-4.jpg width=20%></span><span><img src=http://test.shop.com/media/wysiwyg/sdk/categories-4.jpg width=20%></span>';
            },
            onFailure: function() {
                return false;
            },
            onException: function() {
                return false;
            }
        });

        return true;
    }
</script>
    "));

还有另外一种在/app/code/local/Xinson/News/controllers/Adminhtml/News/Edit.php 的 __construct()

最后加

$this->_formScripts[] = "
    document.getElementById('placeholder_limit').onblur = function(){
        var url = 'http://test.shop.com/serial-codes/';
        new Ajax.Request(url, {
                    method: 'post',
                    onSuccess: function(text) {

        },
                    onFailure: function() {
            return false;
        },
                    onException: function() {
            return false;
        }
                });

            return true;
        }
";
