Question

您好我尝试在固定定位的父元素中使用bootstrap模式。但似乎它没有按预期工作。这是一个例子，

<div class="fixed">
  <div>
    <div>
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-target="#myModal" data-toggle="modal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
  </div>
</div>
</div>

注意：我希望保持HTML结构不变。

Answer 1

问题是什么？它不可点击？

尝试将模态设置为position：relative并为其指定z-index。

见这里： https://codepen.io/anon/pen/wJPWdr

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
  var window: UIWindow?
    var openUrl:NSURL? //This is used when to save state when App is not running before the url trigered


  func application(_ application: UIApplication, openURL url: NSURL, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
  //print("Host: \(url.host!)")
    //let url = url.standardized
    //NotificationCenter.default.post(name: NSNotification.Name(rawValue: "HANDLEOPENURL"), object:url!)
    print("bbb")
    return true
  }
}

Answer 2

简短回答：删除fixed类

此处有同样问题的问题：z-index not working with fixed positioning

或MDN文档：The stacking context

Answer 3

你只需要降低模态背景的z-index，

尝试这个简单的CSS，你很高兴

.modal-backdrop{
    z-index:-1;
}

无法在父元素中使用modal，其位置为fixed
