I am using this spectrogram.js from github to plot spectrogram and obtain frequency values in real-time.
Github Repo
I have written this extra stopSong function:
function stopSong() {
var analyser = audioContext.createAnalyser();
var ctx = new AudioContext();
var osc = ctx.createOscillator();
osc.connect(ctx.destination);
osc.start(0);
spectro.stop();
var freqData= new Uint8Array(analyser.frequencyBinCount);
analyser.getByteFrequencyData(freqData);
//var f = Math.round(freqData[1]);
// var text = f + ' Hz';
var idx = 0;
for (var j=0; j < analyser.frequencyBinCount; j++) {
if (freqData[j] > freqData[idx]) {
idx = j;
}
}
var frequency = idx * ctx.sampleRate / analyser.fftSize;
console.log(frequency);
//document.getElementById("frec").innerHTML = text;
}
But everytime i am running it it give 0 as output. Can anybody tell whats wrong with my code.
You need to connect the oscillator to the analyser:
oscillator.connect(analyser);
Also you might want to call getByteFrequencyData multiple times, maybe in requestAnimationFrame, or something like setTimeout.

Is there any way to add colors to a sublist's row depending upon a condition. I have loaded a saved search to show output on a sublist. But now I want to highlight the rows if the difference between todays date and audit date(search output) is more than 100 days.
var search = nlapiLoadSearch('customrecord_cseg_properties', 'customsearch52');
var columns=search.getColumns();
var sublist = form.addSubList('customsublist', 'staticlist', 'List of properties');
for(var i = 0; i< columns.length; i++){
sublist.addField('customcolumn'+i, 'text', columns[i].getLabel());
}
var result= search.runSearch();
var resultIndex = 0,resultStep = 1000,resultSet,resultSets = [];
do {
resultSet = result.getResults(resultIndex, resultIndex + resultStep);
resultSets = resultSets.concat(resultSet);
resultIndex = resultIndex + resultStep;
} while (resultSet.length > 0);
nlapiLogExecution('DEBUG','The Total number of rows is',resultSets.length);
for(var w= 0; w<resultSets.length ;w++){
for(var x=0; x<columns.length; x++){
var temp;
temp=resultSets[w].getText(columns[x]);
if(temp==null || temp==''){
temp=resultSets[w].getValue(columns[x]);
}
sublist.setLineItemValue('customcolumn'+x, Number(w)+1,temp);
}
I couldn't find any functions in UI Builder API for Netsuite for doing this. Please let me know if there is any other way to do this. Above is the code which I have used to display search result in suitelet.
There is no native api for that.
You can do it by mainpulating the DOM on the client script onInit function.
Just keep in mind that DOM manipulation are risky since they can break if NetSuite will chnage the DOM structure.
My emails usually has more than one Labels assigned. I like to search emails with a specific label then list them into the spreadsheet and show all other labels also assigned to the email.
Here's what i have so far, can't figure out how to get the other labels...
function myFunction() {
var ss = SpreadsheetApp.getActiveSheet();
var threads = GmailApp.search("label:Test");
for (var i=0; i<threads.length; i++)
{
var messages = threads[i].getMessages();
for (var j=0; j<messages.length; j++)
{
var sub = messages[j].getSubject();
var from = messages[j].getFrom();
var dat = messages[j].getDate();
ss.appendRow([dat, sub, from])
}
}
}
As far as Apps Script is concerned, Gmail labels are applied to threads and not to individual messages. (There are other contexts where this isn't necessarily true, as a Web Apps post details).
So, you should use the getLabels method of the Thread object. It then makes sense to structure the output so that each row corresponds to a thread, rather than a message. This is what I did below. The script takes subject/from/date from the first message in each thread. The 4th column is the comma-separated list of labels, except the one you search for.
function myFunction() {
var sheet = SpreadsheetApp.getActiveSheet();
var search_label = 'Test';
var threads = GmailApp.search('label:' + search_label);
var output = [];
for (var i=0; i < threads.length; i++) {
var firstMessage = threads[i].getMessages()[0];
var sub = firstMessage.getSubject();
var from = firstMessage.getFrom();
var dat = firstMessage.getDate();
var labels = threads[i].getLabels();
var otherLabels = [];
for (var j = 0; j < labels.length; j++) {
var labelName = labels[j].getName();
if (labelName != search_label) {
otherLabels.push(labelName);
}
}
output.push([dat, sub, from, otherLabels.join(', ')]);
}
sheet.getRange(1, 1, output.length, output[0].length).setValues(output);
}
I prefer not to add one row at a time, instead gathering the double array output and inserting it all at once. Of course you can use appendRow as in your script. Then you wouldn't necessarily need a comma-separated list,
sheet.appendRow([dat, sub, from].concat(otherLabels));
would work.
Hi im trying to export the Emailadresses from the senders in a label in Gmail Called "Suarez". But it's just running and never completing, it should be about 372 emails. Is it to much to print to the logger?
Here is what im trying:
function getEmailsadresses(){
var threads = GmailApp.search("in:suarez");
for (var i = 0; i < threads.length; i++) {
var messages = threads[i].getMessages();
for (var m = 0; m < messages.length; m++) {
var msg = messages[m].getFrom();
}
}
Logger.log(msg()); // log from address of the message
}
I use a script embedded in an spreadsheet the reads every messages in every threads in a Label that could probably be a good starting point for you.
My specific use case was to log SMS messages that my android phone sends me as emails each time I send or receive a text message.
So it will work for you by just changing the label name and maybe remove the data filtering I added on the message. Since I have a lot of data I set up a time trigger task manager to works in small bunches to avoid exceeding time limit.
Usage is simple : run the "startSMSLog" and go have a couple of coffees until the cell A1 in the spreadsheet stops being RED... that's it.
Code below : the start function
function startSMSLog(){
var triggerID = ScriptApp.newTrigger('countSMSLogEmails').timeBased().everyMinutes(5).create().getUniqueId();
var thisTrigger = PropertiesService.getScriptProperties().setProperty('thisTriggerSMS',triggerID);
PropertiesService.getScriptProperties().setProperty('current thread SMS',0);
var sh = SpreadsheetApp.getActive().getSheetByName('SMS'); // change to the name of your sheet
sh.getRange('A1').setBackground('red');
countSMSLogEmails(true);
}
and the "working" code :
function countSMSLogEmails(clearSheet){
var sh = SpreadsheetApp.getActive().getSheetByName('SMS');
var start = Number(PropertiesService.getScriptProperties().getProperty('current thread SMS'));
var CallLogThreads = GmailApp.getUserLabelByName('SMS').getThreads(start,10);
if(CallLogThreads.length==0){
sh.sort(2,false);
sh.getRange('A1').setBackground('#FFC');
var triggers = ScriptApp.getProjectTriggers();
var thisTrigger = PropertiesService.getScriptProperties().getProperty('thisTriggerSMS');
for(var n in triggers){
if(triggers[n].getUniqueId()==thisTrigger){ScriptApp.deleteTrigger(triggers[n])};
}
sh.getRange('A1').setValue('Subject (Log on '+Utilities.formatDate(new Date(), Session.getScriptTimeZone(), "dd-MMM-yy HH:mm")+')');
return;
} else {
PropertiesService.getScriptProperties().setProperty('current thread SMS',start+CallLogThreads.length);
}
var data = [];
for(var n=0;n<CallLogThreads.length;n++){
var thread = CallLogThreads[n];
Logger.log('thread message count = '+thread.getMessageCount());
var msg = thread.getMessages();
var msgData = [];
for(var m in msg){
var msgDate = msg[m].getDate();
var msgSubject = msg[m].getSubject();
var msgBody = msg[m].getBody().replace(/[\n\r]/g,' ').replace(/'/g,"'").replace(/ /g,"!").replace(/&/g,"&").replace(/"/g,'"')
.replace(/>/g,'>').replace(/</g,'<').replace(/<br \/>/g,'\n').replace(/<br>/g,'\n');
msgData.push([msgSubject,msgDate,msgBody]);
}
data.push(msgData);
}
var dataTotal = [];
if (clearSheet==true) {
dataTotal.push(['subject', 'date', 'message']);
}
for(var n in data){
dataTotal = dataTotal.concat(data[n]);
};
Logger.log(JSON.stringify(dataTotal));
if (clearSheet==true) {
sh.clearContents();
sh.getRange(1,1,dataTotal.length,dataTotal[0].length).setValues(dataTotal);
}else{
sh.getRange(sh.getLastRow()+1,1,dataTotal.length,dataTotal[0].length).setValues(dataTotal);
}
}
I would like to know how can I get the data from mongodb in Template.templatename.rendered function. I tried click event on other template and it's all working fine and return the results i wanted. But what I need is to rendered the chart on load. But I could not get any data from the mongodb.
//poll.js
var drawPollChart = function(){
//returns data on other template methods except for
//Template.templatename.rendered
var dist = getDistinctQuestionId();
alert('dist:'+dist);
var data_x =[];
for(var i=0; i< 1; i++)
{
var count = getDataCount(dist[i]);
var uniq = getDistinctResponseBucket(dist[i]);
for(var j=0; j<uniq.length; j++)
{
//alert('data:' + count[uniq[j]] + ", label:" + uniq[j]);
data_x.push({
data : count[uniq[j]],
label: uniq[j]
});
}
}
Template.pollChart.rendered = function() {
//can't draw a thing cause can't get any data from mongodb
drawPollChart();
};
Help please? Thanks in advance.
Just because the template is rendered doesn't mean the DB is connected.
Use Meteor.status().status to detect the state of the connection. For example you could wait to render the pollChart-template at all until Meteor.status().status === 'connected'.
I've been trying to whip up a quick google script to count rsvps for the invite response spreadsheet for a wedding. The script worked perfectly for a week as new entries were added to the spreadsheet, then suddenly stopped working with the following error message in each cell:
Error: Service Times Out: Apps Script
The script itself is simple. It queries the relevant column (there are multiple events) and then checks to see whether there is some response spefied by the user - "YES", "NO", or a blank, typically.
What does this error mean, and does anyone have any suggestions for fixes?
function sumRSVP(response, rsvpType) {
var rsvpCol = 7;
if (rsvpType == "rehearsal") rsvpCol = 8;
if (rsvpType == "brunch") rsvpCol = 9;
var mySum = 0;
var sh = SpreadsheetApp.getActiveSheet();
for( i=2; i<177; i++){
var rsvp = sh.getRange(i, rsvpCol).getValue();
var nguests = sh.getRange(i, 6).getValue();
if(nguests != "" && rsvp == response){
mySum = mySum + parseFloat(nguests);
}
}
return mySum;
}
Hopefully the wedding went well. This was asked some time ago but has been viewed over 300 times at this post and I believe is important:
Data should not be extracted from a spreadsheet in a loop. The data needed should be extracted in a batch to an array and the array evaluated in the loop.
See docs reference at:
https://developers.google.com/apps-script/guide_common_tasks#OptimizeScripts
You can write scripts to take maximum advantage of the built-in caching, by minimizing the number of reads and writes. Alternating read and write commands is slow. To speed up a script, read all data into an array with one command, perform any operations on the data in the array, and write the data out with one command.
function sumRSVP(response, rsvpType) {
var rsvpCol = 7;
if (rsvpType == "rehearsal") rsvpCol = 8;
if (rsvpType == "brunch") rsvpCol = 9;
var mySum = 0;
var sh = SpreadsheetApp.getActiveSheet();
// start at row 2 - uses columns 6-9
var data = sh.getRange(2, 6, 177 - 1 , 4).getValues();
for(var i=0; i<data.length; i++){
var rsvp = data[i][rsvpCol - 6];
var nguests = data[i][0];
if(nguests != "" && rsvp == response){
mySum = mySum + parseFloat(nguests);
}
}
return mySum;
}
