Detect support for srcdoc in iFrames

Does anyone know how to detect if the srcdoc attribute of iFrame is supported by the browser without relaying on version checks, etc?

Solution

  • This should do the trick in JavaScript executed in a browser:

    !!("srcdoc" in document.createElement("iframe"))
