打印多个iframe内容

Question

I want to print only the content of multiple iframes in a webpage at once when print button is clicked.

I already tried this code.

function printall() {
  window.print();
  for (var i=0; i<window.frames.length; i++) {

    window.frames[i].focus();
    window.frames[i].print();
  }
}

After adding this code , If i click on print it prints one by one ie it prints first iframe and again click on print it prints second iframe.

But I want to print all the iframes at once when clicked on print button.

Answer 1

this doesn't seem to be possible with Javascript (at least not in an easy or clean way)

• Select a printer and silently print
• window.print() - without opening the print window

But if you tell us a bit more about the desired output there may be another solution like reading the content of every iframe, join it together and then print it.
