trombone | experimental rewrite of Trombone

Pressing instrument sound button a sound is played. I've tried to match each array element on console.log but is not working.

Why does "console.log" match to array and sometimes not? I mean, console.log sometimes shows the correspondent instrument name to the sound heard, sometimes the wrong name is shown. The first "console.log" is the only one which matches to the sound played.

I have a pure css hamburger menu based on this codepen and I made my hamburger menu only show up on devices with 768px width and below, the hamburger menu also has some transitions when opening and closing to make it look smooth but the problem is that when the page is refreshed, you can see the menu show up for a split second before it transitions under the header. This can also be seen when you're manually resizing the viewport from a width larger than 768px and when it gets to 767px, you can the see the menu appear for a split second before it disappears. Please I need help to make this behaviour stop. Below is the code required to recreate this problem:

This question may seem similar to other questions but my hamburger menu uses checkbox to function and shows up at 768px width and below and I've been running into issues trying to close the open hamburger menu when the window/document is clicked. I successfully got it to work using several ways but it still doesn't work as intended. The hamburger menu closes on document click alright, but the hamburger menu no longer closes on hamburger menu click as it originally should. I have very little knowledge of Javascript/Jquery but I understand the bits I used to make other parts of the code work, but I just can't figure out how to make this particular one work. Below is the code required to recreate the problem:

hello. I'm trying to create multiple unique instances of an object using a loop. Here's my code:

I'm tunning a query for data that may not exist . When this is the case, the callback is not run. As I understand from the docs, it should run and the snapshot.val() should be null, isn't it?

There's a stripped down example here: http://surfmaps.eu/trombone/case.html

There's a console.log inside the callback that is not executed.

Am I missing something here?

Bye and thanks, Luís

This is the question about how to parse "unparseable" output into json, or to something easily consumable as json. This is "little" bit behind trivial stuff, so I'd like to know, how do you solve these things in principle, it's not about this specific example only. But example:

We have this command, which shows data about audio inputs:

I recently started using SPARQL and have an exercise to make a query that will allow me to get song titles that have a singer as their only vocalist? In this case being John Lennon the only singer.

I have a beatles.ttl data file, so far I was able to select all the songs where John Lennon is lead singer, however there are songs where he is lead singer with 2 other band members.

I am in need of some help regarding SPARQL construct queries. How is it possible to make a CONSTRUCT query with an IF condition to get triples that enable rules representation?

Like a CONSTRUCT query that enables us to express the following rules:

1. If X is an instance of a C1 class, and C1 is a subclass of a C2 class, then X is an instance of C2.

and

1. If X has in P1 property the value V, and P1 is a subproperty of P2, then X has in property P2 the value V.

For this Data File (Beatles.ttl)

I have a timetable from a teacher. This teacher has his own classes and she should be able to enter his class-topic from the hour in the database.

I am trying to figure out how this is possible.

Here is my problem (code): I have in my teacher html view a field that has different names
