将输入类型从复选框更改为单选框的 JS 脚本？

Question

我有一个带有列表的 mailpoet 表单，这样人们就可以从多个订阅中进行选择。

  <label class="mailpoet_segment_label">title</label>
  <label class="mailpoet_checkbox_label">
    <input type="checkbox" class="mailpoet_checkbox" name="data[form_field_YzQxYmU0Njc5OTk5X3NlZ21lbnRz][]" value="9" data-parsley-required="true" data-parsley-group="segments" data-parsley-errors-container=".mailpoet_error_segments" data-parsley-required-message="Selecteer een lijst" data-parsley-multiple="dataform_field_YzQxYmU0Njc5OTk5X3NlZ21lbnRz" wtx-context="2278B8F3-5F48-4047-9B6D-131ED484ADF5">

问题是，我只想让他们选一个。基本上，列表不需要是一个复选框，而是一个单选按钮（只允许一个选择）。

这是生成列表的方式，所以我无法编辑 html。

将输入类型替换为收音机的正确脚本是什么（并且只允许一个选择。）

Answer 1

您可以使用document.querySelectorAll 获取所有复选框。然后将属性 type 从 checkbox 设置为 radio.

只需确保所有单选框的名称相同，这样你就只能select一个。

// Select by input type
const checkboxes = document.querySelectorAll("input[type='checkbox']");
// Select by class
// const checkboxes = document.querySelectorAll(".mailpoet_checkbox");

checkboxes.forEach(checkbox => {
  checkbox.setAttribute("type", "radio");
});
