It's supposed to be rendered in black on a white background."> ![]() The content you see here will never be affected by the CSS of its parent container. On a particular page, I needed to list them to let the user preview and choose one.īut to prevent the CSS of the current website from affecting the style of these templates, I figured out that using an iframe with the srcdoc attribute was the cleanest solution. ![]() In an application, a user could create emails and save them as templates. To illustrate how this isolation from the JavaScript and CSS is handy, let’s take a look at these two situations. The iframe can still behave in annoying or malicious ways - triggering a popup or autoplaying videos, for instance. Nevertheless, as you will see in this guide, the separation is not so perfect. That is one of the valid purposes to use an iframe: to provide a measure of separation between your application and the iframe content. Thus, it will be isolated from the JavaScript and CSS of the parent. What you must keep in mind when thinking about iframes is that they let you embed an independent HTML document with its own browsing context. ![]() Here is another example in which we display a button to tweet your webpage on Twitter: You may have crossed paths with it when you had to include a third-party widget (like the famous Facebook like button), a YouTube video, or an advertising section on your website.įor instance, the code below will display a 500px square with the Google homepage within: What is an iframe, and when do you use it?ĭevelopers mainly use the iframe tag to embed an HTML document within another. Finally, we’ll talk about how you can secure your iframes to avoid potential vulnerabilities. We’ll go through most of the features the iframe element provides and talk about how you use them, as well as how iframes can be useful for overcoming some tricky situations. To help you form your own opinion and sharpen your developer skills, we will cover all the essentials you should know about this controversial tag. Besides, it’s not that hard to secure them, so you won’t have to worry about your user’s machine becoming compromised. I believe that their bad reputation should not prevent you from relying on them they have many legitimate uses cases. Even though all modern browsers support them, many developers write endless articles advising against using them. That is the best way to get an issue addressed so that your map works in all the latest ArcGIS apps that are built on 4.x.įor now, if you need to have those popups working in your StoryMap you can create an app with your web map from one of the older 3.x templates (like Story Map Basic or the Basic Viewer) and then embed that app in your story.The iframe element (short for inline frame) is probably among the oldest HTML tags and was introduced in 1997 with HTML 4.01 by Microsoft Internet Explorer. Since this issue is not something we can address on the StoryMaps side, I would suggest contacting Esri Support and reporting the issue you are observing as a bug in the new map viewer/JSAPI. This is an issue with the JSAPI 4.x not supporting some things that the 3.x JSAPI did. Although the 4.x version is more modern in every way, there are still some differences between the two and a few things that the 4.x version still does not support. Here's a link to view your map in the new map viewer.įigure: 22 Libyan Detention Centres ()ĪrcGIS StoryMaps, the new map viewer, and many other ArcGIS apps (like the new Dashboards, Experience Builder, etc.) are built with the latest (4.x) version of The ArcGIS API for JavaScript, while the classic map viewer is build with the older 3.x version. I hate to just add a hyperlink to the video, there has to be away to make this work as I am attempting If you view your web map in the new map viewer (rather than the classic map viewer) you'll see the same issue you see in your StoryMap. I am referencing some other video content, however it is coming from a different source, and it is displaying flawlessly as you can see from the links above and in the screenshot below:įor this I was able to direct link to this source with simple html tags: There you should see the "Figure 22: Libyan Detention Centres" web map embeded into the story map. Click on the subsection for "The Western Mediterranean Route" and the scroll up to the first web map you find, located at the bottom of the subsection "The Central Mediterranean Route". ![]() Here is a link to the public facing story map. Here is a link to the public facing web map. Here is the code I am using which is adapted from the solution provided here by tech support. This remains an issue, despite the documentation having been updated in February of this year.īelow is a screenshot of what is happening in the web map:
