如何使模态的背景可以单击

How do I make the background of a modal clickable?

本文关键字：单击 背景 何使 模态      更新时间：2023-09-26

我想创建一个可以插入网站的聊天框。我一直在使用Bootstrap Modal来实现这一点。

我希望当用户在模态之外单击时，我的模态不会关闭。但网站背景应该仍然是可点击/可选择的，这样用户仍然可以在网站上执行操作。

这是我迄今为止编写的代码。

$(window).load(function () {
  $('#myModal').modal({ backdrop: 'static', keyboard: false});
  $('#myModal').modal('show');
});
function myFunction() {
  $('#myModal').modal('toggle');
  window.alert('Hello');
}
.vertical-alignment-helper {
  display:table;
  height: 100%;
  width: 100%;
  pointer-events:none; /* This makes sure that we can still click outside of the modal to close it */
}
.vertical-align-center {
  /* To center vertically */
  display: table-cell;
  vertical-align: middle;
  pointer-events:none;
}
.modal-content {
  /* Bootstrap sets the size of the modal in the modal-dialog class, we need to inherit it */
  width:inherit;
  height:inherit;
  /* To center horizontally */
  margin: 0 auto;
  pointer-events: all;
  float: left;
  max-width: 250px;
  background-color: #ffffff;
}
.textarea-nonresizable {
  height: 10em;
  border-radius: 1em;
  outline: none; /* removes the default outline */
  resize: none; /* prevents the user-resizing, adjust to taste */
}
.header-cl {
  background-color: #262626;
  color: #FFFFFF;
  border-bottom-width: 0px;
}
.header-f {
  font-size: 14px;
  font-weight: bold;
}
.body-cl {
  background-color: #c7c8c9;
}
.foot-cl {
  border-top-width: 0px;
  padding-top: 0px;
  background-color: #c7c8c9;
  color: #FFFFFF;
}
.btn-ft {
  background-color: #3f1603;
  color: #FFFFFF;
}
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open>.dropdown-toggle.btn-primary {
  color: #FFFFFF;
  background-color: #3f1603;
}

          </button>
          <h4 class="modal-title header-f">Contact Us</h4>
        </div>
        <div class="modal-body body-cl">
          <textarea class="form-control textarea-nonresizable" id="comment" placeholder="Type your message here"></textarea>
        </div>
        <div class="modal-footer foot-cl">
          <div style="float:left;color:#FFFFFF;font-size: 11px;line-height: 34px;">
            Powered by <strong>Stackoverflow</strong> </div>
          <button type="button" class="btn btn-primary btn-ft" onclick="myFunction()">Start Text</button>
        </div>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

您可以在.modal和.modal-backdrop上使用pointer-events: none;。或者用display: none; 隐藏.modal-backdrop

.modal {
    pointer-events: none;
}
.modal-backdrop {
    display: none;
}

示例

老实说，如果你要修改引导模式的功能这么多，你还不如使用一个固定位置的自定义元素，而不是试图对抗引导CSS。
