如何在ajax请求后从控制器返回单个值? Joomla 2.5

标签: joomla joomla2.5

我正在从这样的视图中对控制器进行ajax调用

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

并在控制器中 我有一个像这样声明的任务方法

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

我得到了这个回复

如何仅返回测试值?

4 个答案:

答案 0 :(得分:1)

回显所有输出文本,然后放置一个die();之后

答案 1 :(得分:1)

你必须在任务结束时添加Jexit();你将摆脱完整的HTML。您也可以使用die(),但如果有Jexit()则为什么。         功能编辑()         {          //你的代码          Jexit();         }

答案 2 :(得分:1)

您可以在url字符串中使用Jexit(),exit()或添加&amp; format = raw或在控制器函数中使用给定代码:

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

答案 3 :(得分:0)

发现它..在url字符串的末尾..你需要附加&amp; format = raw 所以请求将是

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 );
        });

!毕竟这很容易。
