我经常使用这样的代码:

$(document).on("click", ".cChatSmileyWindow", $.proxy(function(e) {
    var windowID = $(e.currentTarget).parent().parent().parent().data("windowid");
}, this));

有没有更好的方法来做到这一点？HTML看起来像这样:

<span class="dropdownMenu dropdownArrowRight dropdownArrowBottom dropdownOpen" id="cChatSmileyBox1" data-windowid="1">
    <ul class="cChatSmileyList">
        <li>
            <span class="cChatSmileyListSmiley cChatSmileyWindow">
                <!-- ... -->
            </span>
        </li>
    </ul>
</span>

我试过了,$(e.currentTarget).parent('dropdownMenu').data("windowid");但它不起作用.

有没有内置的PHP函数来获得以下结果？

    $rgba = "rgba(246, 24, 35, 0.8)";
    $splittedRgba = splitRGB($rgba);

    $rgb = "rgb(246, 24, 35)";
    $splittedRgb = splitRGB($rgb); // splitRGB is the function I need
    /*
        $splittedRgba['r'] = 246;
        $splittedRgba['g'] = 24;
        $splittedRgba['b'] = 35;
        $splittedRgba['a'] = 0.8;

        $splittedRgb['r'] = 246;
        $splittedRgb['g'] = 24;
        $splittedRgb['b'] = 35;
        $splittedRgb['a'] = 1;
    */

更新: 我想知道如何插入(N)并在用户单击指定的div时将其删除.
