我正在编码音乐程序的申请表。该程序是根据日期应用的。当前静态内容，每个程序都有很多日期。我需要找到一种对“应用按钮”进行编码的方法，以便它可以“动态”地在参数中获取日期和程序。这是我的jsfiddle 

$('a.ApplyNowDate').attr('href', function() {
  return 'http://schoolofofrock.com/?programme=Reggae&date=' + $(this).prev().text() + '/';
})
.ApplyNowDate,
.ApplyNowDate:hover {
  background: #e91e63;
  color: #fff;
  display: inline-block;
  font-size: smaller;
  padding: 5px 10px;
  margin-left: 10px;
}

我已经成功获取URL参数中的日期。我如何获得该程序？我应该使用什么jQuery选择器？甚至有可能吗？

使用$(this).closest(".vc_tta-panel-body").find(".TheProgramme").text()

$(this).closest(".vc_tta-panel-body")进入包含链接和程序的DIV。然后.find(".TheProgramme")在DIV中搜索程序。

$('a.ApplyNowDate').attr('href', function() {
  return 'http://schoolofofrock.com/?programme=' + $(this).closest(".vc_tta-panel-body").find(".TheProgramme").text() + '&date=' + $(this).prev().text() + '/';
})
.ApplyNowDate,
.ApplyNowDate:hover {
  background: #e91e63;
  color: #fff;
  display: inline-block;
  font-size: smaller;
  padding: 5px 10px;
  margin-left: 10px;
}
