ajax - validateLogin is an undefined function.(javascript exception ) -

-

hi getting error undefined function think code alright can in case? please , suggest me tutorial getting data through webservice via ajax method.

<script type="text/javascript" language="javascript" src="scripts/jquery-1.4.1.js">    function validatelogin() {          $('input[type=button]').attr('disabled', true);         $("#login").html('');         var loginid = $('#txt_id').attr('value'); // username         var password = $('#txt_pwd').attr('value'); // password          $.ajax({              type: "post",             url: "webservice.asmx/validatelogin",             data: "lognid=" + loginid + "&password=" + password,             contenttype: "application/json; charset=utf-8",               success: function (result) {                     returnval = result.d;                     alert(returnval);                 },                  error: function (xmlhttprequest, textstatus, errorthrown) {                     returnval = '';                     },         });      }   </script>

you can't link javascript source file , define code in same tag. split them 2 separate tags this:

<script type="text/javascript" src="scripts/jquery-1.4.1.js"></script> <script type="text/javascript">   function validatelogin() {          $('input[type=button]').attr('disabled', true);         $("#login").html('');         var loginid = $('#txt_id').attr('value'); // username         var password = $('#txt_pwd').attr('value'); // password          $.ajax({              type: "post",             url: "webservice.asmx/validatelogin",             data: "lognid=" + loginid + "&password=" + password,             contenttype: "application/json; charset=utf-8",               success: function (result) {                     returnval = result.d;                     alert(returnval);                 },                  error: function (xmlhttprequest, textstatus, errorthrown) {                     returnval = '';                     },         });      }   </script>

citing mdn on issue:

src

this attribute specifies uri of external script; can used alternative embedding script directly within document. script elements src attribute specified should not have script embedded within tags.

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...
