How to get a value of a property in JSON array from extjs store? -

-

i have been trying dynamically generate check box value in json array json store.

{"modulecatogery":[{"menu":"msu"},{"menu":"schedule"},{"menu":"market_dashboard"},{"menu":"fe_reference"},{"menu":"qc_tools"},{"menu":"quickqc_voice"},{"menu":"quickqc_data"},{"menu":"marketqc_voice"},{"menu":"marketqc_data"},{"menu":"surgery"},{"menu":"file_inventory"},{"menu":"market_tracker"},{"menu":"drive_route_tracker"},{"menu":"tickets"},{"menu":"ticket_tracker"},{"menu":"assets"},{"menu":"metrics"},{"menu":"daily_status"},{"menu":"daily_processing"},{"menu":"weekly_workflow"},{"menu":"customer_questions"},{"menu":"kpi_performance_metrics"},{"menu":"collection_metrics"},{"menu":"operations_dashboard"},{"menu":"production_dashboard"},{"menu":"support_dashboard"},{"menu":"revenue_tracker"},{"menu":"deployment_tracker"},{"menu":"tickets"},{"menu":"ticket_tracker"},{"menu":"asset_management"},{"menu":"generate_shipment"},{"menu":"shipment_tracker"},{"menu":"resources"},{"menu":"schedule"},{"menu":"tracker"}]}

how can values associated "menu" in above json.? if can have each , every value array can dynamically assign these generate check box group.

thanks in advance.

you can iterate store:

store.each(function(record) {     var menu = record.get('menu'); });

edit: since you're saying doesn't work dynamic data think iterate before has completed loading. sure handle iteration after load can following:

store.on({     //listener fires everytime after store has loaded     load: function() {         store.each(function(record) {              var menu = record.get('menu');              //do stuff         });     } }); store.load();

if want execute code first time store loads can use callback function on load() method:

store.load(function() {     store.each(function(record) {         var menu = record.get('menu');         //do stuff     }); });

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
