<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访问Sing Sing？这就是我在想的......
$(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());
});
});

我会用selector替换".edit-panel"，因为那是按钮所在的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());
同
var sing = $(".content").text().trim();
