javascript - Some localStorage items are not being displayed -

-

i have 5 items in localstorage, however, when try output files,

only 2 items being output, , not all.

js puts localstorage:

$(document).ready(function () {     $.fn.savetocart = function (id, iname, ialbum, iprice) {         var quantity = 0;         if (localstorage.getitem('product_' + id) === null) {             quantity = 1;         } else {             var tempitem = json.parse(localstorage.getitem('product_' + id));             var tempquantity = parseint(tempitem['quantity']);             quantity = tempquantity + 1;         }         var cartitem = {             'quantity': quantity,             'name': iname,             'album': ialbum,             'price': iprice         }         localstorage.setitem('product_' + id, json.stringify(cartitem));     };

cart js:

function shoppingcart() {      var output;     var productname;     var productalbum;     var productquantity;     var productprice;     var productsubtotal = 0;     var totalprice;       (var = 0; < localstorage.length - 1; i++) {         var keyname = localstorage.key(i);         if (keyname.indexof('product_') == 0) {             var product = localstorage.getitem(keyname);              var product = localstorage.getitem('product_' + i);              var result = json.parse(product);              totalprice = 0;             productname = result.name             productalbum = result.album;             productquantity = parseint(result.quantity);             productprice = parsefloat(result.price).tofixed(2);             productsubtotal = parseint(productquantity) * parsefloat(productprice).tofixed(2);              outputname = "<div id='cart-table'><table><tr><td><b>name: </b>" + productname + "</td></tr></div>";             outputalbum = "<tr><td><b>album: </b>" + productalbum + "</td></tr>";             outputquantity = "<tr><td><b>quantity: </b>" + productquantity + "</td></tr>";             outputprice = "<tr><td><b>price: </b> eur " + productprice + "</td></tr>";             outputsubtotal = "<tr><td><b>sub-total: </b> eur " + productsubtotal + "</td></tr></table><br><br>";               var totaloutput = outputname + outputalbum + outputquantity + outputprice + outputsubtotal;              document.getelementbyid("cart-contents").innerhtml = document.getelementbyid("cart-contents").innerhtml + totaloutput;             totalprice += parsefloat(totalprice) + parsefloat(productsubtotal);             productsubtotal = productsubtotal + productsubtotal;         }         i++;       }     totalprice = productsubtotal;      localstorage.setitem("price", totalprice);      var outputtotal = "<br><br><h1><table><tr><td><b>total:</b> eur " + totalprice + "</td></tr></table></h1>";     document.getelementbyid("total-price").innerhtml = document.getelementbyid("total-price").innerhtml + outputtotal;   }  function clearcart() {      localstorage.clear();     document.location.reload(true);  }  window.onload = shoppingcart;      </script>

html:

<div id="cart-contents"></div> <div id="total-price"></div>

also, have problem, total price not getting calculated correctly. getting 28.12 total of 14.06 + 16.40. why happening?

to give idea:

change loop this: for (var = 0; < localstorage.length; i++){.

and don't add i++; end of loop's body.

both cause loop not hit items, different reasons.

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
