How do I use JavaScript write to a different web page?

问题

I'm trying to take user input from one web page and write it to a different web page that already exists (all in the same domain if that matters). I debug the JavaScript (see below) and see that it iterates through the for loop correctly and builds the correct information to write, but it does not write it to the other web page. Not sure what I'm doing wrong but would greatly appreciate some help!

listitem='';

function newHTML() {

     for (i=0;i<3;i++) {
          cc=document.forms['mainform'].list[i];
          if (cc.checked) listitem+=cc.value;
     }
     HTMLstring='<HTML>\n';
     HTMLstring+='<HEAD>\n';
     HTMLstring+='<TITLE>TESTING</TITLE>\n';
     HTMLstring+='</HEAD>\n';
     HTMLstring+='<BODY bgColor="blue">\n';
     HTMLstring+='"'+listitem+'"\n';
     HTMLstring+='< /BODY>\n';
     HTMLstring+='< /HTML>';
     alert(HTMLstring);
     newwindow=window.open('writeToThisPage.html');

     newwindow.document.write(HTMLstring);
     newwindow.document.close();

     window.open('writeToThisPage.html');
}

Here's a demo. And you should avoid using document.write()

//open a new window
//"newWindow" is your reference to it
var newWindow = window.open();

//"newWindow.document.body" is the body of the new window
var newWindowBody = newWindow.document.body

//let's test by adding a text node to it
var text = document.createTextNode('foo');
newWindowBody.appendChild(text);

This is you looking for :P I hope!!!

     HTMLstring='<HTML>\n';
     HTMLstring+='<HEAD>\n';
     HTMLstring+='<TITLE>TESTING</TITLE>\n';
     HTMLstring+='</HEAD>\n';
     HTMLstring+='<BODY bgColor="green">\n';
     HTMLstring+="<p>NinaMoxa</p>\n";
     HTMLstring+="<a href=\"javascript:self.close()\">Cerrar</a>\n";
     HTMLstring+='< /BODY>\n';
     HTMLstring+='< /HTML>';
     alert(HTMLstring);


     var ventana=window.open('','name','height=400,width=500'); 
     ventana.document.write(HTMLstring);
     ventana.document.close();

It seems all is OK, except one thing. You're opening the same window again immediately you've created the new document. Just leave this last line out:

window.open('writeToThisPage.html');
