在CSS Bootstrap jquery modal中显示模态背景之外的元素 [英] Exposing element outside modal-backdrop in CSS Bootstrap jquery modal

问题描述

我使用CSS Bootstrap的Modal功能，它的工作完美。但是，我想添加一个功能，当模态对话框打开并且网页的其余部分被.modal-backdrop覆盖时，页面结构范围内不同位置的外部元素之一可以是暴露在背景顶部：

I'm using CSS Bootstrap's Modal feature, and it's working perfectly. However, I want to add a functionality that while the modal dialog is open and the rest of the web page is covered up by the .modal-backdrop, one of the outside elements from a different place within the scope of the page's structure can be exposed on top of the backdrop:

<div id="outside-element">
  I want this element exposed even while the modal is active,
  upon clicking the button in the modal dialog box
</div>

<div id="help-box" class="modal fade" data-backdrop="static" data-keyboard="false" data-show="true" tabindex="-1" role="dialog" aria-labelledby="help-label" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
              Click this button to show the outside element:
              <button type="button" class="btn" aria-hidden="true" id="test-item">Click it!</button>
            </div>
        </div>
    </div>
</div>

<script type="text/javascript">
  (function($) {
     $('#test-item').click(function() {
        $('#outside-element').attr('style','zIndex:1041');
     });
  })(jQuery);
</script>

正如你在上面的尝试中看到的，我设置了外部的z-index元素到1041，其比模式背景设置（1040）高一个。这不是完成我想要的（即，将＃outside元素放在模态背景顶部），即使代码是声音和工作（即，它是最终修改z索引）。

As you can see in my current attempt above, I'm setting the z-index of the outside element to 1041, which is one higher than the .modal-backdrop setting (1040). This is not accomplishing what I want it to (namely, placing the #outside-element on top of the modal backdrop), even though the code is sound and "working" (that is, it's definitively modifying the z-index).

推荐答案

如果你有一个小提琴来显示你的代码，我们可以运行它，看看发生了什么。

It would be great if you have a fiddle to show your code in a way that we can run it and see what's going on.

您将需要包含元素的位置，以使z-index生效：

You will need to include the position of the element, for a z-index to take effect:

#outside-element {
   position: relative;
   z-index: 1041;
}
