play beep on specific plan - 3r1ck - 25.10.2019

Hello colleagues, my idea is to be able to reproduce a beep (notification sound) on a specific plan, with a group address. when its state is 1, it reproduces the sound, the problem is what reproduces on all pages and must be in one



Adjunto el código javascript

Code:
$(function(){ 

  var context= new AudioContext();
 
function jsNota(frecuencia){
        var o= context.createOscillator();
        g=context.createGain();
        o.connect(g);
        o.type="sine";
        o.frequency.value=frecuencia;
        g.connect(context.destination);
        o.start(0);
        g.gain.exponentialRampToValueAtTime(0.00001,context.currentTime +1.5);
    }
grp.listen('1/1/1', function(object, state) {
    if (state == 'value' && object.value ) {
      jsNota(1174.659, function() {
      });
    }
  }, true);
 
  });

Gracias

Hi,

Just add a extra condition:
Code:
if (currentPlanId == 1){
  //your code
}
Here is also a code i use if the sound must be repeated until the object is false
Code:
$(function(){
  var locked;
  var ctx = new(window.AudioContext || window.webkitAudioContext || window.mozAudioContext || window.oAudioContext || window.msAudioContext);
  var Beeping;
 
  function beep(duration, freq, vol, cb) {
    var osc = ctx.createOscillator();
    osc.frequency.value = freq;
    var volumeNode = ctx.createGain();
    volumeNode.gain.value = (vol/1000);
    osc.connect(volumeNode);
    volumeNode.connect(ctx.destination);    
    osc.start ? osc.start(0) : osc.noteOn(0);
    setTimeout(function () {
    osc.disconnect();
    if (typeof cb == "function") {
     cb();
    }
   }, duration);
  }
 
  /* beep each time value is true note that 3rd listen parameter must be set to true to execute the callback each time new value arrives otherwise callback is executed only when value changes */
  function startbeep(){
    var ChromeDelay = 0;
    if (document.hidden && !!window.chrome){
      ChromeDelay = 1500;
    }
    setTimeout(function(){
      if (!locked) {
        locked = true;
        // duration , freq
        beep(300, 1500, 50, function() {
          locked = false;
        });
      }
    }, ChromeDelay);
  } 

  // Function to start beep interval
  function StartBeepTimer(){
    // Jump to correct page
    //showPlan(3);
    // Set delay timer to start after x seconds
    setTimeout(function(){
      // Start feedback polling every second
      if (!Beeping) {
        // Run once to bypass the first delay
        startbeep();
        Beeping = setInterval(function(){ startbeep(); }, 2000);
      }
    }, 50); // Set higher value then 50 for extra delay after stop and start beep
  }

  // Function to stop beep interval
  function StopBeepTimer(){
    // Stop feedback polling every second
    if (Beeping) {
      clearInterval(Beeping);
    }
    Beeping = null;
  }
 
  // Creta elistener to start audio beep
  grp.listen('21/0/1', function(object, state) {
    if (state == 'value' && object.value ) {
       StartBeepTimer();
    } else if( state == 'value' && object.value == false){
        StopBeepTimer();
    }
  }, true);
  
});

Erwin
