javascript - jQuery 如何仅删除某些元素的类

Question

我有一个 jQuery 项目，我在其中循环遍历所有具有相同类的元素列表。我需要的是删除第一个两个元素类。因此，我正在使用 .removeClass() 方法。但是，我不知道如何使用该方法，只能删除前两个。它正在移动所有这些。有人可以在不改变我的代码方向的情况下帮助我吗。

function putSiblingsInTableForEachH2() {
        // line above sets function that will ultimately store siblings of each h2.toggler into a HTML table
        var togglerHeaders = $("h2.toggler");
        //  line above sets variable togglerHeaders to all h2 elements with a class of ".toggler"
        for (i = 0; i < togglerHeaders.length; i++) {
            // line above: for loop that loops through array "togglerHeaders"
            var currentH2Element = togglerHeaders[i];
            // line above sets variable currentH2Element to togglerHeaders at position i
            if (currentH2Element == togglerHeaders[0] || togglerHeaders[1]) {
                $("h2").removeClass("toggler");
            }
            var siblingsofH2 = $(currentH2Element).nextUntil("h2.toggler");
            // line above access siblings that are in h2.toggler element
            // line says: set variable "siblingsofH2" to the current h2.toggler element you're on actual sibling elements but only siblings that are in between current element and next element that is "h2.toggler"
            $(siblingsofH2).wrapAll("<table></table>");
            // line above says: after correct sibling elements are stored to variable siblingsofH2 wrap elements in HTML table
        } // line ends for loop 
    } // line ends function
    putSiblingsInTableForEachH2();
    // line above actually runs function

当然 $("h2").removeClass("toggler"); 会从所有中删除类，因为它指的是所有。

我稍微编辑了你的台词:

if (i < 2) {
    $(currentH2Element).removeClass("toggler");
}
