Send existing Notifications from a script

[thetobyde]

Hey :)
I want to re-write the “MMM-SmartTouch” Module to have an “App-Dock-Bar”. I was able to change the CSS file to have this look now:

I also was able to add the first 4 buttons with costom icons. I want to have these icons to change the pages with “MMM-pages”.
The pages module listens on these Notifications: PAGE_CHANGED, pageNumber

But I cant get it to work. This is my smartTouch.js and my nodeHelper:

MMM-smartTouch.js :

//Main Menu Bar
        var main_menu = document.createElement("div");
        main_menu.className = "main-menu"
        main_menu.id = "navbar"
        home_div.appendChild(main_menu)
        var main_menu_ul = document.createElement("ul");
        main_menu_ul.className = "navbar-nav"
        main_menu.appendChild(main_menu_ul)

	//Page 1 (Home Screen)
        var main_menu_li_restart = document.createElement("span");
        main_menu_li_restart.innerHTML = "<span class='fas fa-home fa-3x'></span>" + "&nbsp" + "&nbsp" + "&nbsp" + "&nbsp";
        main_menu_li_restart.className = "li-t"
        main_menu_ul.appendChild(main_menu_li_restart)
        main_menu_li_restart.addEventListener("click", () => this.sendSocketNotification("PAGEONE", {}));

	//Page 2 (Wetter)
        var main_menu_li_restart = document.createElement("span");
        main_menu_li_restart.innerHTML = "<span class='fas fa-cloud-sun fa-3x'></span>" + "&nbsp" + "&nbsp" + "&nbsp" + "&nbsp";
        main_menu_li_restart.className = "li-t"
        main_menu_ul.appendChild(main_menu_li_restart)
        main_menu_li_restart.addEventListener("click", () => this.sendSocketNotification("SHUTDOWN", {}));

	//Page 3 (Drive Bilder)
        var main_menu_li_restart = document.createElement("span");
        main_menu_li_restart.innerHTML = "<span class='far fa-image fa-3x'></span>" + "&nbsp" + "&nbsp" + "&nbsp" + "&nbsp";
        main_menu_li_restart.className = "li-t"
        main_menu_ul.appendChild(main_menu_li_restart)
        main_menu_li_restart.addEventListener("click", () => this.sendSocketNotification("SHUTDOWN", {}));

	//Page 4 (Party Bilder)
        var main_menu_li_restart = document.createElement("span");
        main_menu_li_restart.innerHTML = "<span class='far fa-image fa-3x'></span>" + "&nbsp" + "&nbsp" + "&nbsp" + "&nbsp";
        main_menu_li_restart.className = "li-t"
        main_menu_ul.appendChild(main_menu_li_restart)
        main_menu_li_restart.addEventListener("click", () => this.sendSocketNotification("SHUTDOWN", {}));
        
        //Power Off Button
        var main_menu_li_shutdown = document.createElement("span");
        main_menu_li_shutdown.innerHTML = "<span class='fa fa-power-off fa-3x'></span>" + "&nbsp" + "&nbsp" + "&nbsp" + "&nbsp";
        main_menu_li_shutdown.className = "li-t"
        main_menu_ul.appendChild(main_menu_li_shutdown)

        //Onclick event to send shutdown notification
        main_menu_li_shutdown.addEventListener("click", () => this.sendSocketNotification("SHUTDOWN", {}));

        //Restart Button
        var main_menu_li_restart = document.createElement("span");
        main_menu_li_restart.innerHTML = "<span class='fa fa-repeat fa-3x'></span>" + "&nbsp" + "&nbsp" + "&nbsp" + "&nbsp";
        main_menu_li_restart.className = "li-t"
        main_menu_ul.appendChild(main_menu_li_restart)
        main_menu_li_restart.addEventListener("click", () => this.sendSocketNotification("RESTART", {}));

and my nodeHelper.js:

if (notification === "PAGEONE") {
              console.log("Page1!")
              require('child_process').this.sendSocketNotification("PAGE_CHANGED", 1);
          }

	  if (notification === "SHUTDOWN") {
              console.log("Shutting Down!")
              require('child_process').exec('shutdown -h now', console.log)
          }

          if (notification === "RESTART") {
              console.log("Restarting Magic Mirror!")
              require('child_process').exec('sudo reboot', console.log)
          }

nothing happens when i touch the first (Page1) icon…

Thx for help! :) Toby

@thetobyde in your click handlers, ‘this’ points to the button causing the click.

this is why we do
var self=this
and use self. in handlers and callbacks
instead of this.

you should see the error reported in the developers window console

[thetobyde]

@sdetweil thx for the fast answer. I change „this.send…“ to „self.send…“ but did not work sadly… i also changed the payload from 1 to 0, because the notifications from MMM-pages are zero-based. So page 1 is PAGE_CHANGED, 0…

The var self = this is written by the Developer of MMM-SmartTouch

[sdetweil]

@thetobyde did step thru the code w the developers window source tab?

[sdetweil]

u changed the code here from this. to self.
=> this.sendSocketNotification("SHUTDOWN
and all similar

[thetobyde]

@sdetweil i changed the code in the nodeHelper from this. to self.

[thetobyde]

@sdetweil

Like this :)

[sdetweil]

@thetobyde and the module code with the buttons?

[thetobyde]

@sdetweil didt change that because it worked for the pre-existing Shutdown and Reboot button from the developer of MMM-smartTouch… isnt it right?

[sdetweil]

@thetobyde said in Send existing Notifications from a script:

require('child_process').this.sendSocketNotification("PAGE_CHANGED", 1);

well, you are not launching a program to chnage the page, and don’t need to send this down to the node_helper
as he has to send it back up to the module to send the notfication,

just do the sendNotification from the module (note its not sendsocketNotification(to my node helper) , just sendNotification(to other modules)
