bootstrap.js如何使背景变灰

我正在尝试调试一个遗留的Web应用程序,该应用程序使用bootstrap.js来提升模式,并使下面的页面变灰。警告,我不是JS / HTML / CCS开发人员,但显然现在这是我的。

代码可以正常运行,具体取决于iframe。当iframe由标准html组成时,它似乎工作正常。当iframe由WebFocus生成的这种奇怪的HTML组成时(只能在IE中正确呈现)。

无论如何,当模态打开时,对DOM进行以下更改:

这个div标签被添加到body元素中:

<div class="modal-backdrop fade in"></div>

相关的风格是:

/*media all*/
.in.modal-backdrop {
    filter: alpha(opacity=50);
    opacity: 0.5;
}


/*media all*/
.fade.modal-backdrop {
    filter: alpha(opacity=0);
    opacity: 0;
}

此外,open-modal样式应用于body元素,如下所示:

<body class="modal-open">

使用相关的样式:

/*media all*/
.modal-open {
    overflow: hidden;
}

现在我希望模态背景样式必须应用于除空div标签之外的其他东西才能工作。这是如何运作的?为什么在应用于一种类型的iframe而不是另一种iframe时会起作用。

iframe如下:

<iframe name="Report Content" width="100%" height="400" title="Webfocus HTML Report" id="htmlReportFrame" src="/path/to/webfocus/report?reportParam=123456" onreadystatechange="readyStateChange()" onload="return readyStateChange();">Your
            browser does not support IFRAMES</iframe>

iframe的报告引用(/ path / to / webfocus / report?reportParam = 123456)返回:

它看起来像标准的html,除了它引用不存在的本地图像文件(例如file:/// C:/IBIUniqueName0.png)。我相信它们是使用某种奇怪的mime类型传送到浏览器的,但我不知道如何。

我可以发布更多代码,但我需要删除敏感信息。
