Question

I have opened a new window, and now I have a button in this new window. Under this button there is a JavaScript function which should submit the form and insert some content into a <p>. This “to-add” content also has a html element (close button).

This inserting job is not working. Here is what I tried:

myWindow.document.write("<scrip" + "t>function closeme(){ document.getElementById('danke').innerHTML='thanks <input type=\'button\' onclick=\'window.close()\'/>'; } </sc" + "ript>");

Can someone please help me out?

Answer 1

As said in the comments there are better ways to insert scripts, but in the interests of answering the question, you have to escape the escape characters as well so that they will be present in the output.

myWindow.document.write("<scrip" + "t>function closeme(){ " + 
"document.getElementById('danke').innerHTML='thanks <input type=\\\'button\\\' " + 
"onclick=\\\'window.close()\\\'/>'; } </sc" + "ript>");

(line breaks added for readability)
