Iframe

Note. The task interface configuration guide describes the features of the HTML/JS/CSS editor. You can also try creating a task interface in Template Builder.

To add an inline frame to a task, use the {{iframe src=<object URL>}} component. Example:

{{iframe src=url width="100px" height="100px"}}

"300px"
height

Height of the frame in pixels. Set in the following units:

  • Pixels. For example, height="100px";

Enables sandbox mode, which restricts working in the frame.

To disable certain restrictions, you can use the following values (separate with spaces if combining them):

  • "allow-orientation-lock" allows lock and unlock methods from the Screen Orientation API.

  • "allow-popups" allows popup windows (for example, using window.open or target="_blank").
  • "allow-popups-to-escape-sandbox" allows pop-ups not to inherit sandbox mode (for example, so that in a popup window with JavaScript it is allowed without "allow-scripts" for a frame).
  • "allow-presentation" allows using the Presentation API.
  • "allow-same-origin"allows loading frame content (interprets this as content from the same source as the parent document). Blocks popup windows, so it can be used to open content safely.

  • "allow-scripts" allows running and executing scripts. However, creating popup windows is prohibited.
  • "allow-top-navigation" allows opening frame links in the parent document.

  • "allow-top-navigation-by-user-activation" allows opening a frame link clicked by the user in the parent document.
