如何在js中的复选框数组上将选中的属性设置为false

Question

我的复选框

  <div class="col-md-3" style="padding-left:15 !important;">
                            <div class="icheckbox_minimal-grey checked disabled" style="position: relative;"><input class="alanlar" type="checkbox" disabled="" name="gunlukAlanlar[]" value="tarih" checked="" style="position: absolute; opacity: 0;"><ins class="iCheck-helper" style="position: absolute; top: 0%; left: 0%; display: block; width: 100%; height: 100%; margin: 0px; padding: 0px; background: rgb(255, 255, 255); border: 0px; opacity: 0;"></ins></div>
                            <label class="control-label" style="margin-left: 5px;color:red;">Tarih</label>
                            </div>
<div class="col-md-3" style="padding-left:15 !important;">
                        <div class="icheckbox_minimal-grey checked disabled" style="position: relative;"><input class="alanlar" type="checkbox" disabled="" name="gunlukAlanlar[]" value="saat" checked="" style="position: absolute; opacity: 0;"><ins class="iCheck-helper" style="position: absolute; top: 0%; left: 0%; display: block; width: 100%; height: 100%; margin: 0px; padding: 0px; background: rgb(255, 255, 255); border: 0px; opacity: 0;"></ins></div>
                        <label class="control-label" style="margin-left: 5px;color:red;">Saat</label>
                        </div>
<div class="col-md-3" style="padding-left:15 !important;">
                        <div class="icheckbox_minimal-grey checked disabled" style="position: relative;"><input class="alanlar" type="checkbox" disabled="" name="gunlukAlanlar[]" value="Order Adı" checked="" style="position: absolute; opacity: 0;"><ins class="iCheck-helper" style="position: absolute; top: 0%; left: 0%; display: block; width: 100%; height: 100%; margin: 0px; padding: 0px; background: rgb(255, 255, 255); border: 0px; opacity: 0;"></ins></div>
                        <label class="control-label" style="margin-left: 5px;color:red;">Order Adı</label>
                        </div>

JQuery 库

<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script> 

JS代码

$("input[name='gunlukAlanlar[]']")[2].prop("checked", false);

但它不起作用。我希望未选中索引 2。但它不起作用。

而不是在 jQuery 元素集合上引用数组索引（无论如何都不起作用） - 坚持使用 JQ 并使用.eq()

此外，您的代码将一个不可见的复选框（ opacity: 0 ）设置为 false （ prop("checked", false); ） - 当它们都未选中时...

在此，我已将其设置为可见“选中”复选框。 那只是一个 css class 所以很容易摆脱。

 $("input[name='gunlukAlanlar[]']").eq(1).prop("checked", false);

 <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script> <label><input class="alanlar" type="checkbox" name="gunlukAlanlar[]" id="gunlukAlanlar[]" checked value="saat" /> //index 0</label> <label><input class="alanlar" checked type="checkbox" name="gunlukAlanlar[]" id="gunlukAlanlar[]" value="modelii">//index 1</label> <label><input class="alanlar" checked type="checkbox" name="gunlukAlanlar[]" id="gunlukAlanlar[]" value="tarih">//index 2</label> <label><input class="alanlar" checked type="checkbox" name="gunlukAlanlar[]" id="gunlukAlanlar[]" value="musteri">//index 3</label>
