Javascript Iframe innerHTML

Question

Does anyone know how to get the HTML out of an IFRAME I have tried several different ways:

document.getElementById(\'iframe01\').contentDocument.body.innerHT         


        

Answer 1

You can use the contentDocument or contentWindow property for that purpose. Here is the sample code.

function gethtml() {
  const x = document.getElementById("myframe")
  const y = x.contentWindow || x.contentDocument
  const z = y.document ? y.document : y
  alert(z.body.innerHTML)
}

here, myframe is the id of your iframe. Note: You can't extract the content out of an iframe from a src outside you domain.
