模态打开时，将类添加到主体

问题描述

我的登录模式有问题。一个模式打开时，有人点击忘记密码链接在我登录模式。 （一种模式打开另一种模式）所以我通过添加所有必要的属性来清除所有事物。
例如：

 < span data-toggle =modaldata-target =＃forgot-pin- popupdata-dismiss =modal>忘记密码？< / span> 
  

但我注意到它不会将 .modal-open 类添加到当我的第二个模态被打开时（没有这个类，样式显示很奇怪）。所以我手动使用这个js脚本。

  $（'。modal'）。on（'hidden.bs.modal'，函数（）{
 if（$（'。modal'）。hasClass（'in'））{
 $（'body'）。addClass（'modal-open'）; 
 } 
}）; 
  

当我尝试切换模型6次时，完美地工作但。它不会再工作。无法想象为什么。我无法向您展示一个示例，因为它位于我的制作网站上。有没有人会遇到类似的问题？ .modal

  $（'body'）。on（'hidden.bs.modal'，如果（$（'。modal.in'）。）（$ body）。 $ b}）; 
  

还要确保你的模态不应该嵌套到 .modal class

$（'body'）。on 'hidden.bs.modal'，function（）{if（$（'。modal.in'）。length）{$（'body'）。addClass（'modal-open'）;}}）; $（ （click，function（）{console.log（$（body）。attr（class））;}） < script src =https://ajax.googleapis.com/ajax/libs/jquery/2.1。

I'm having a problem with my login modals. One modal open when someone click forgot password link on my sign in the modal. (One modal open in another modal) So I came everything clean by adding all necessary attributes.Eg:

  <span data-toggle="modal" data-target="#forgot-pin-popup" data-dismiss="modal">Forgot password?</span>

But I notice it won't add .modal-open class to the body when my second modal is open(styles are shown weird without this class). So I manually use this js script.

  $('.modal').on('hidden.bs.modal', function () {
  if($('.modal').hasClass('in')) {
   $('body').addClass('modal-open');
   }
 });

Works perfectly BUT when I try switching models like 6 times. It won't work again. Can't imagine why. I can't show you an example because it's on my production site. Does anyone face the similar problem like this?

解决方案

Try to use body instead of .modal

$('body').on('hidden.bs.modal', function() {
  if ($('.modal.in').length) {
    $('body').addClass('modal-open');
  }
});

Also make sure that your modal should not be nested into .modal class

$('body').on('hidden.bs.modal', function() {
  if ($('.modal.in').length) {
    $('body').addClass('modal-open');
  }
});
$(".btn-primary").on("click", function() {
  console.log($("body").attr("class"));
})
