Question

我是JavaScript新手，使用iframe-resizer库时出现问题。

我的iFrame有一个Angular组件HTML文件，其中包含以下代码。正如您所看到的，我包含iframeResizer.min.js文件，并且我正在使用srcdoc动态构建iFrame的内容（我在此框架内容中包含iframeResizer.contentWindow.min.js文件）：

<script type='text/javascript' src='../iframeResizer.min.js'></script>

<iframe id="myIframe" srcdoc="<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.<p>But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?<p>On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains.</p><script type='text/javascript' src='../iframeResizer.contentWindow.min.js'></script>" scrolling="no"></iframe>

<script>iFrameResize({log:true}, '#myIframe')</script>

我的组件也有一个scss文件，其中包含以下内容：

iframe {
    width: 1px;
    min-width: 100%;
}

我没有看到我的iFrame被调整大小，也没有在控制台中看到任何iframe-resizer日志。什么都没发生。知道为什么会这样吗？我究竟做错了什么？我是否需要Angular指令来公开必要的变量和行为 - 如果是这样，你有一个例子吗？对于noob问题感到抱歉，并提前感谢您的帮助。

FWIW，当我不得不以角度方式做同样的事情时，我使用这里的方法来创建一个指令来应用于iframe来添加一个加载处理程序：

然后在我做的加载处理程序中

        let $frame=$('#the-iframe');
        setInterval(function () {
            let height = parseInt($frame.contents().find('body').height());
            if (height !== oldHeight) {
                $frame.height(height + 30);
                oldHeight = height;
            }
        })

加30是填充问题，您的使用案例可能不同
