access JavaScript variable in new window -

-

this first javascript attempt, apologize if things little mangled.

i have 2 html pages (certificate1.html , certificate2.html). i'm trying prompt user his/her name on certificate1.html, pass information certificate2.html. @ point user's name displayed in certificate (s)he can print.

both html pages reference same javascript file (certificate1.js). first page calls passname():

function passname() {     firstn = document.frmusername.infirstn.value;     lastn = document.frmusername.inlastn.value;    // alert(firstn); //    // alert(lastn); //     var cert = window.open("certificate2.html");     cert.firstn = firstn;     cert.lastn = lastn;     //alert(cert.firstn); //good     //alert(cert.lastn); //good }

this seems working correctly. i'm stuck function placename() certificate2.html calls. have firing onload, , know it's accessing function correctly (i stuck alert in there , came up). don't know how access firstn , lastn variables passed cert in passname(). i've tried document.firstn "undefined." how can access firstn , lastn variables (think i) passed?

thanks! -kristin

update:

got it!!!

i didn't need access via window.opener - had passed in variables window, able access them directly.

function placename() {     //alert(firstn);     document.getelementbyid("pusername").innerhtml = firstn + " " + lastn; }

thanks guys!! -kristin

html localstorage (html5) http://diveintohtml5.info/storage.html

in first file :

localstorage.setitem("firstn", document.frmusername.infirstn.value);

in second 1 :

var firstn = localstorage.getitem("firstn");

but think should done using php or @ least not js

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
