采用以下法典:

    // Bind the click event to the thumbnails.
    $("ul.hpList").on("click", "a.hpThumb", function (event) {

        event.preventDefault();

        var $this = $(this),

        // Surely there has to be a smarter way to do this.
            $hpList = $this.parents("ul.hpList");

        changeItem($this, $hpList);

    });

我如何更好地确定活动必须具备的根本祖先因素。 我觉得我非常积极地寻找OM。

问题回答

我不清楚你实际上试图找到什么,但:

http://api.jquery.com/event.target/“rel=“nofollow”>event.target 在你的手里,确定哪些实际的OM要素触发了这一事件。

使用<代码>(本项),确定投递人所属的多功能元素,可能是同一事物,也可能是活动目标的母体。

使用.closest()找到适合特定选择者的最接近的祖先。

尝试:

$("ul.hpList").on("click", "a.hpThumb", function (event) {
    event.preventDefault();
    var $this = $(this),
    // Surely there has to be a smarter way to do this.
    $hpList = $("ul.hpList").has($this);
    changeItem($this, $hpList);
 });
