Question

<ul class="info">                        
  <li data-edit="string">
    <span class="content">
      Sing Sing
    </span>
    <div class="edit-panel">
      <button data-action="delete">Delete</button>
      <button data-action="edit">Edit</button>
    </div>
  </li>
</ul>

点击删除按钮后，如何在此处访问Sing Sing？这就是我正在尝试的......

$(selector).each(function(){
  var $mainElement = $(this);    
  $mainElement.find("[data-action=delete]").off().on("click", function(){           
    var sing = $(this).parents("[data-edit]").find("#gogo").text($(this).val());             
  });
});

我只会将selector替换为".edit-panel"，因为这是按钮所在的div。

从内容中获取文本，而不是试图遍历jquery树直接点击它，也就是替换

var sing = $(this).parents("[data-edit]").find("#gogo").text($(this).val());

带

var sing = $(".content").text().trim();

jQuery尝试访问span中的文本
