The example in this article describes the method of JS returning the value of the frameBorder attribute in an iframe. Share it with everyone for your reference. The specific analysis is as follows:
The frameborder attribute specifies whether to display the border around the frame.
<!DOCTYPE html> <html> <body> <iframe id="myframe" src="/default.asp" frameborder="0"> <p>Your browser does not support iframes.</p> </iframe> <p>The frameborder is set to: <script> document.write(document.getElementById("myframe").frameBorder); </script> <p> </body> </html>
I hope this article will be helpful to everyone’s JavaScript programming design.
