jquery - Javascript match string against string in array -

-

i have set of input fields, each class "smarty_address_check"

<input type="text" class="smarty_address_check" value="this new value" /> <input type="text" class="smarty_address_check" value="this value has been unchanged" /> etc

what need

  • for each input field value
  • compare value each of values in array (array called smarty_address_check)
  • if matches, something.

the values in array original default/example values of input fields, , if user hasn't changed them want act on that.

var exampleaddresspresent = false;     (var = 0; i<smarty_address_check.length; i++) {         $('.smarty_address_check').each(function() { //for each of inputs             if (smarty_address_check[i].match($(this).val())) { //if match against array                 var exampleaddresspresent = true; //example address present                 console.log($(this).attr("id")); //store id of unchanged input              }         });     }

i feeling bad programming logic, not mention can't work out why isn't working properly. want compare 1 string against another. know of better way approach this?

you don't need match() compare 2 strings. there common === compare operator

if(smarty_address_check[i] === $(this).val()) {

edit: if index of array matches index/position of input, can avoid outer loop using same index

$('.smarty_address_check').each(function(index) { //for each of inputs     if (smarty_address_check[index] === $(this).val()) { //if match against array         exampleaddresspresent = true; //example address present         console.log($(this).attr("id")); //store id of unchanged input     } });

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
