Question

我正在尝试将小的“ x”关闭按钮添加到uk-modal弹出窗口的右上角。我如何正确添加其php代码和CSS以及可能的JavaScript？

我尝试将以下1、2个代码添加到3个代码块中：

1）我添加的第一个代码：

<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>

2）添加了第二个代码：

<div id="my-id">
    <div class="uk-modal-dialog">
        <button class="uk-modal-close-default" type="button" uk-close></button>
    </div>
</div>

<div id="my-id">
    <div class="uk-modal-dialog">
        <button class="uk-modal-close-outside" type="button" uk-close></button>
    </div>
</div>

3）到弹出的此代码块：

   <div class="uk-modal-dialog">
    <div class="uk-modal-header">
            <h2><?php echo esc_attr_e( $options['popuptitle'] ); ?></h2>
        </div>
        <div class="uk-modal-content"><?php echo stripslashes( $options['popuptext'] ); ?></div>
        <div class="uk-modal-footer">
            <button id="button1" type="button" class="uk-button uk-button-large uk-button-<?php echo esc_attr_e( $options['popupbutton1style'] ); ?><?php if( $options['popupbuttonoptions'] != 'button-1-redirect' ) echo ' uk-modal-close'; ?>"><?php echo esc_attr_e( $options['popupbutton1text'] ); ?></button>
        </div>
    </div>
</div>

我希望在弹出窗口上获得“ x”关闭按钮的真实位置，但是它不在适当的位置，因此也无法关闭模式弹出窗口。

我希望像下面的图片那样得到它：

看看是否对您有帮助：

.close-button {
  border: none;
  display: inline-block;
  padding: 8px 16px;
  vertical-align: middle;
  overflow: hidden;
  text-decoration: none;
  color: inherit;
  background-color: inherit;
  text-align: center;
  cursor: pointer;
  white-space: nowrap
}

.topright {
  position: absolute;
  right: 0;
  top: 0
}

<header style="background-color:#000;color:#fff;">
  <span onclick="document.getElementById('YourModalBox').style.display='none'" class="close-button topright">&times;</span>
</header>

别忘了为模态YourModalBox设置“ id”，并将其应用于模态框的标题，这样它就进入<div>内并停留在右上角。

我仍在开发中的Web应用程序中的一个实时示例（请注意，由于我没有发布完整的body HTML，因此该示例无法正确显示，因为它太长且与值无关的答案：

// When the user clicks anywhere outside of the modal, close it	
window.addEventListener('click', function(event) {
  if (event.target == document.getElementById('mod_mec')) {
    document.getElementById('mod_mec').style.display = "none";
  }

  if (event.target == document.getElementById('mod_therm')) {
    document.getElementById('mod_therm').style.display = "none";
  }
});

#btn_menu {
  background-color: #000;
}

#btn_menu:hover {
  animation-name: change;
  animation-duration: 0.6s;
}

@keyframes change {
  from {
    background-color: #000
  }
  top {
    background-color: #777
  }
}

#subs {
  opacity: 0.7;
}

#subs:hover {
  cursor: pointer;
  opacity: 1;
  animation-name: hovering;
  animation-duration: 0.6s;
}

@keyframes hovering {
  from {
    opacity: 0.7;
  }
  top {
    opacity: 1;
  }
}
