jQuery 找到最接近的 ID 并删除 class 个名字之一

Question

嘿，我正在想办法找到下一个最接近 DIV 的 ID然后我需要替换其 class 名称中的 one (class="something0 something1 something2").

我要处理的是这个html:

<div class="col-sm-10">
    <select class="tips form-control searchable-select-holder-req" data-tooltip="example 1" data-val="" id="environment" name="environment" style="width: 260px; display: none;">
        <option value="1">IT</option>
        <option value="2">FRASTRUCTURE</option>
        <option value="3">blah 2</option>
        <option value="4">blah 3</option>
        <option value="5">blah 4</option>
        <option value="6">blah 5</option>
        <option value="7">blah 6</option>
        <option value="8">SPARE</option>
        <option value="9">LAB</option>
        <option value="10">STUDY</option>
    </select>
    <div tabindex="0" class="searchable-select" style="width: 260px; min-width: 260px;">
        <div class="tips searchable-select-holder searchable-select-holder-req" data-tooltip="example 1" data-tag="environment"></div>
        <div class="searchable-select-dropdown">
            <span>Search:</span> 
            <input type="text" class="searchable-select-input" style="width: 250px; max-width: 185px; background-color: rgb(254, 231, 231);" />
            <div class="searchable-scroll has-next">
                <div class="searchable-has-privious searchable-select-hide">...</div>
                <div class="searchable-select-items mCustomScrollbar _mCS_2" style="font-family: Courier New, Courier, monospace;">
                    <div id="mCSB_2" class="mCustomScrollBox mCS-bodyScroll mCSB_vertical mCSB_inside" style="max-height: 185px;" tabindex="0">
                        <div id="mCSB_2_container" class="mCSB_container" style="position:relative; top:0; left:0;" dir="ltr">
                          <div class="searchable-select-item" data-value=""></div>
                          <div class="searchable-select-item" data-value="1">IT</div>
                          <div class="searchable-select-item" data-value="2">FRASTRUCTURE</div>
                          <div class="searchable-select-item" data-value="3">blah 2</div>
                          <div class="searchable-select-item selected" data-value="4">blah 3</div>
                          <div class="searchable-select-item" data-value="5">blah 4</div>
                          <div class="searchable-select-item" data-value="6">blah 5</div>
                          <div class="searchable-select-item" data-value="7">blah 6</div>
                          <div class="searchable-select-item" data-value="8">SPARE</div>
                          <div class="searchable-select-item" data-value="9">LAB</div>
                          <div class="searchable-select-item" data-value="10">STUDY</div>
                        </div>
                        <div id="mCSB_2_scrollbar_vertical" class="mCSB_scrollTools mCSB_2_scrollbar mCS-bodyScroll mCSB_scrollTools_vertical mCSB_scrollTools_onDrag_expand" style="display: block;">
                            <div class="mCSB_draggerContainer">
                                <div id="mCSB_2_dragger_vertical" class="mCSB_dragger" style="position: absolute; min-height: 30px; top: 0px; display: block; height: 104px; max-height: 175px;" oncontextmenu="return false;">
                                    <div class="mCSB_dragger_bar" style="line-height: 30px;"></div>
                                </div>
                                <div class="mCSB_draggerRail"></div>
                            </div>
                        </div>
                    </div>
                </div>
                <div class="searchable-has-next">...</div>
            </div>
        </div>
    </div>
</div>

我目前在代码的 data-tag="enviroment" 部分更改我的 inner text可以没有问题。现在从那里我需要找到 next/closest div with ID of mCSB_2_container 然后找到 DIV 其中有 class of selected and 删除它并将其放在第一个 div项上（此处为空白值）。

这是我当前用于访问 **** 部分的 JS：

$("select").each(function() {
   $('[data-tag="' + this.id + '"]').text(''); //Clears Text
   //$(this).next('#mCSB_2_container').removeClass("selected");
});

从代码中可以看出，我尝试使用 $(this).next('#mCSB_2_container').removeClass("selected"); 但这似乎不起作用，因为它在 mCSB_2_container 中寻找 class 名称 selected。

任何帮助解决这个问题都会很棒！

Answer 1

我想也许你可以做到这一点。

$('.container').click(function(e) {
    e.preventDefault();
    var x = $(this).next().attr('id');
    $('.container').remove(x);
});

<a class="container" id="1" href="#">One</a>
<a class="container" id="2" href="#">Two</a>
<a class="container" id="3" href="#">Three</a>

Answer 2

您可以使用 find() 查找选定的 class，例如：$(this).next('.searchable-select').find('.selected').removeClass("selected");。请参阅下面的工作片段：

$("select").each(function() {
  $('[data-tag="' + this.id + '"]').text(''); //Clears Text
  $(this).next('.searchable-select').find('.selected').removeClass("selected");
  $(this).next('.searchable-select').find('.searchable-select-item:first-child').addClass('selected');
});

.selected {
  background: #f00;
}
