如何在ajax请求后从控制器中返回单个值？的Joomla 2.5

我想提出一个AJAX调用一个控制器上的从视图这样如何在ajax请求后从控制器中返回单个值？的Joomla 2.5

jQuery.ajax({ 
       type: "POST", 
       url: "index.php?option=com_virtuemart&amp;view=participate&amp;task=participate_request&amp;virtuemart_product_id=2&amp;virtuemart_category_id=5&amp;tmpl=component&amp;Itemid=101", 
       data: { name: "John", location: "Boston" } 
      }).done(function(msg) { 
       alert("Data Saved: " + msg); 
     });

，并在CONTROLER 我有一个任务方法声明如下

public function participate_request(){   
     echo 'test'; 
     return false; 
    }

我得到这个响应

您可以使用Jexit（），出口（）或添加&格式=原在URL字符串或控制器功能使用给定的代码：

$app = &JFactory::getApplication(); 
$app->close()

函数参与控制器 – themis 2012-08-13 05:30:47

发现它..在URL字符串..你需要连接&格式的结束=原因此请求将

jQuery.ajax({ 
       type: "POST", 
       url: "index.php?option=com_virtuemart&amp;view=participate&amp;task=participate_request&amp;virtuemart_product_id=2&amp;virtuemart_category_id=5&amp;tmpl=component&amp;Itemid=101&format=raw", 
       data: { name: "John", location: "Boston" } 
      }).done(function(msg) { 
       alert("Data Saved: " + msg); 
     });

！毕竟这么容易。

你只需要添加Jexit（）在你的任务&结束，你将摆脱完整的HTML。你也可以使用die（），但为什么如果有Jexit（）。 function edit（） { //您的代码 Jexit（）; }
