从图书馆自定义的复选框中获取值并以表单发送

  • 772

我决定用这种复选框来装饰我的表单

https://www.codehim.com/bootstrap/bootstrap-toggle-switch-with-text/ 一切正常，但是我现在如何获取元素的状态，设计是基于按钮的？形体空空飞走。

javascript

    以下是如何使用它，如文档中所写 - 在我看来，如果仅在 js 中，您可以获取类的存在/不存在active并将其添加到表单中。

    此自定义复选框本身，即使配置为label+checkbox，也不允许切换复选框并将其传输到表单。

    但是，如果您放弃bootstrap.min.js并编写自己的处理程序来添加活动类，则可以稍微简化任务。大约如下面的代码所示。要检查复选框的操作，只需暂时注释掉样式的最后一行display: none

    而且，是的，bootsrap 具有相同的带有复选框的开关，只需对样式进行一些修改，可能会适合您。

    document.querySelector('.btn').addEventListener('click', e => {
  e.target.classList.toggle('active');
