I have the following code below in which I am using to attempt to dynamically write some javascript into a new html page at the click of a button.

I am however getting an error when attempting to do so I get “unterminated string constamnt”
in theory, this should work:

var html     =  '<!DOCTYPE html>\n'
html    +=  '<html>\n'
html    +=  '<head>\n'
html    +=  '<script type="text/javascript">\n'
html    +=  'function testme() {\n'
html    +=  'alert("the test worked!")\n'
html    +=  '}\n'       
html    +=  '</script>\n'
html    +=  '</head>\n'
html    +=  '<body>\n'
html    +=  '</body>\n'
html    +=  '</html\n'

window.open('','').document.write(html)

    You are missing a closing > on the last line

    html    +=  '</html\n'  <-- Missing a greater than

    should be

    html    +=  '</html>\n'

    If the code is inline and not in an external script, you will need to break up the closing script tag. 

    html    +=  '</scr' + + 'ipt>\n';

    also, use semicolons.

    Now the window.open, document.write line looks strange. Most developers would write it as

    var winPop = window.open('','');
winPop.document.open();
winPop.document.write(html);
winPop.document.close();
