javascript - Searching through JSON objects with input from HTML input -

-

i have json file using jquery.

i know how search through items , items related html input.

this tried:

 function search(form) {          $(".products").empty();         $.getjson('products.json', function(data) {             $(data.products).each(function(index, item) {                 if(form == item.name) {                      var input = document.getelementbyid('searchform');                      $('<div/>', {'class':'productname'}).text(item.name).append(                             $('<div/>', {'class':'productdetails', text:'album: '+item.album}),                             $('<div/>', {'class':'productdetails'}).append($('<img>').attr({src:item.source,title:item.name,alt:item.name,class:'productimage'})),                             $('<div/>', {'class':'productdetails', text:'genre: '+item.genre}),                             $('<div/>', {'class':'productdetails', text:'price: '+item.price}),                             $('<div/>', {'class':'productdetails', text:'quantity: '+item.quantity}),                             $('<div/>', {'class':'productdetails', text:'tracks: '+item.tracks}),                             $('<div/>').append(                                     $('<button />', {'class':'productbutton'})                                             .text('add cart.')                                             .click(function(){                                                 $.fn.savetocart(i,item.name, item.album, item.price);                                             })                             )                     ).appendto(".products");                 }   else if (form == item.album) {                      var input = document.getelementbyid('searchform');                      $('<div/>', {'class':'productname'}).text(item.name).append(                             $('<div/>', {'class':'productdetails', text:'album: '+item.album}),                             $('<div/>', {'class':'productdetails'}).append($('<img>').attr({src:item.source,title:item.name,alt:item.name,class:'productimage'})),                             $('<div/>', {'class':'productdetails', text:'genre: '+item.genre}),                             $('<div/>', {'class':'productdetails', text:'price: '+item.price}),                             $('<div/>', {'class':'productdetails', text:'quantity: '+item.quantity}),                             $('<div/>', {'class':'productdetails', text:'tracks: '+item.tracks}),                             $('<div/>').append(                                     $('<button />', {'class':'productbutton'})                                             .text('add cart.')                                             .click(function(){                                                 $.fn.savetocart(i,item.name, item.album, item.price);                                             })                             )                     ).appendto(".products");                    }             });         });     };      $(document).ready(function() {         $('#searchform').submit(function(e) {             e.preventdefault();             search(this);         });     });

html:

   <form name="searchform" id="searchform" > <input name="productname" id="productname" type="text"> <input type="submit" value="search">  </form>

trying code refreshes page.

any idea on how can fix it?

you need prevent form being submitted. can either add return false; @ bottom of search() function (before last };), or remove inline onsubmit , attach submit handler form using jquery, allow use preventdefault():

$(document).ready(function() {   $('#searchform').submit(function(e) {     e.preventdefault();      search(this);   }); });

also, have spelling error in following line:

var input = document.getelementbyid('searhform');

should be

var input = document.getelementbyid('searchform');

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
