我正在努力将我的代码推送到Heroku.在搜索Google和Stack Overflow问题后,我找不到解决方案.这是我尝试"git push heroku master"时得到的结果:

Heroku receiving push

-----> Detected Rails is not set to serve static_assets

....

最后:

我正在尝试构建一个表单,用户可以通过单击"添加选项"按钮添加文本字段.他们还可以通过Jquery动态创建的"删除选项"链接以及文本字段删除添加的字段.

JavaScript的:

$(document).ready(function(){
    $("#add_option").click(function()
      {
        var form = $("form");
        var input_field = '<input type="text" />';
        var delete_link = '<a href="#">remove</a>';
        form.append(input_field + delete_link);

        return false;
    });

    $("a").click(function()
    {
        alert('clicked');
        return false;
    });
});

当我点击"add_option"按钮时,会出现一个新的文本字段和"delete_link".但是当点击JQuery创建的"delete_link"时,浏览器会跟踪链接而不是启动显示"clicked"的弹出窗口.

如何在使用JQuery动态创建dom元素后隐藏它？

我试图使用zend框架检索在url中传递的参数.但当然,它不起作用!我的代码看起来像这样:

生成网址:

<?php echo $this->url(array('controller' => 'poll', 'action' => 'showresults', 'poll_id' => $poll['_id']), null, true) ?>

检索showresultsAction()中的"poll_id"参数:

 $request = new Zend_Controller_Request_Http();
 $poll_id = $request->getParam('poll_id');

问题是$ poll_id是NULL.当我执行$ request-> getParams()的var_dump时,它也是NULL.我已经浏览了Zend Framework文档,但它并不是很有用.任何的想法 ？谢谢 !
