<script>
  function checkNumChecked(ele, limit) {
    var ct = 0,
      siblings = document.getElementsByName(ele.name),
      checked = 0;
    for (ct = 0; ct <= siblings.length - 1; ct++) {
      checked += (siblings[ct].checked) ? 1 : 0
    }
    for (ct = 0; ct <= siblings.length - 1; ct++) {
      siblings[ct].disabled = siblings[ct].checked ? false : (checked == limit) ? true : false
    }
  }

这是我的Checkbox限制器。例如，当我选中2复选框时，其他复选框将被禁用。但是，在取消选中1复选框后，这里出现了问题。它也将删除原始的disabled =“”复选框。它不必删除原始的disabled =“”代码

Answer 1

为了永久禁用您希望代码单独留下的复选框，我在此处所做的是使用自定义数据属性＆＃34; data-permdisable＆＃34;。这告诉代码跳过对元素进行任何更改。

另外，我应该指出你应该检查=＆＃34;检查＆＃34;和残疾=＆＃34;禁用＆＃34;作为形式问题。

<input type="checkbox" value="1" name="malzeme1[]" checked="checked" disabled="disabled" id="checkboxExample1"
    onclick="checkNumChecked(this, 2)" data-permdisable="true">

    Soğan<b class="product-subtitlex"> | + 1 ₺</b>
</label>
<input type="checkbox" value="3" name="malzeme1[]" id="checkboxExample3" onclick="checkNumChecked(this, 2)">
