DOMNodeInserted事件循环 [英] DOMNodeInserted event loop

问题描述

我正在为Facebook开发Chrome扩展（我的第四个问题...），它在喜欢按钮旁添加一个自定义按钮。由于帖子会自动添加到新闻Feed中而不刷新页面，所以每次添加新帖时，都必须添加脚本。

I am developing a chrome extension (my fourth question or so...) for facebook, which adds a custom button beside the "like" button. Since posts are added automatically to the news feed without a page refresh, I have to add the script every time new posts are added.

而且我使用 DOMNodeInserted 事件

问题是当事件被调用时，我将一个新的元素（按钮）插入到页面中，一个循环！

The problem is that when the event is called I insert a new element (the button) to the page and it makes a loop!

我的脚本：

$(document).bind('DOMNodeInserted', function(event) {
    $(".like_link").after('<span class="dot"> · </span><button class="taheles_link stat_elem as_link" title="תגיד תכל&acute;ס" type="submit" name="taheles" onclick="apply_taheles()" data-ft="{&quot;tn&quot;:&quot;&gt;&quot;,&quot;type&quot;:22}"><span class="taheles_default_message">תכל&acute;ס</span><span class="taheles_saving_message">לא תכלס</span></button>');
    $(".taheles_saving_message").hide();
});

推荐答案

这是否有效？提供您不要插入任何更多的 .like_link 元素，当您的元素插入发生时，这应该是无操作的，因为它只会查找包含 .like_link 。

Does this work? Providing that you don't insert any more .like_link elements, this should be a no-op when your element insertion happens, since it only looks for node insertions which contain a .like_link.

$(document).bind('DOMNodeInserted', function(event) {
    $(event.target).find(".like_link").after(
        '<span class="dot"> · </span>' +
        '<button class="taheles_link stat_elem as_link" title="תגיד תכל&acute;ס" type="submit" name="taheles" onclick="apply_taheles()" data-ft="{&quot;tn&quot;:&quot;&gt;&quot;,&quot;type&quot;:22}">' +
            '<span class="taheles_default_message">תכל&acute;ס</span><span class="taheles_saving_message">לא תכלס</span>' +
        '</button>'
    );
    $(event.target).find(".taheles_saving_message").hide();
});
