    Exibir scrollbar (barra de rolagem) via console com JavaScript

    Algumas vezes, por algum erro de programação ou algum outro motivo qualquer a barra de rolagem pode desaparecer da página. Podemos testar se é isso mesmo via console com o código abaixo.
    //Exibir scrollbar (barra de rolagem) via console com JavaScript
    // Criar uma variável com elemento body
    var y =  document.querySelector("body");
    
    // Definir o estilo para exibir a scrollbar no elemento body
    y.style.overflow = "scroll !important";

    command combinations Description: Quickly create operational games using simple box graphics from Phaser3 shapes (v3.13.x). This test game mechanics for enjoyment. Final Artwork added to game mechanisms, prototypes and mechanics as the final pipeline product phase.
    // ============
    //Example 4.1: Prototyping Graphics begins
    // ============
    //create a character avatar using the box prototype method 
    player = box({who: this, whereX: 150, whereY: 100,length:32, width:32, color: 0x0000FF,border: 0xFFFFFF});
    this.physics.add.existing(player);
    player.body.velocity.x = 10; //see update function
    player.body.velocity.y = 50;
    console.log("Stationary Blue character avatar created as 'player' variable.");
    // ------------  
    // OR the direct method using either rectangle or graphics
    //    and set movement velocities. 
    var avatar =  this.add.rectangle(100, 100, 32, 32, 0x0000FF).setStrokeStyle(5, 0x3399CC);
    console.log("Moving Blue character avatar created as 'player' variable.");
    var graphics = this.add.graphics({ fillStyle: { color: 0xFF0000 } });
    graphics.lineStyle(10,0xFF9900,0);
    graphics.strokeRect(100, 100, 32, 32);
    	
    //non-controlled movement (usage AI bot; see Chapter 6)
    graphics.fillRectShape(avatar);
    this.physics.add.existing(avatar);
    avatar.body.velocity.x = 50;
    avatar.body.velocity.y = 10;
    //non-controlled movement (usage AI bot; see Chapter 6)
    this.physics.add.existing(graphics);
    graphics.body.velocity.x = 50;
    graphics.body.velocity.y = 50;
    console.log("Moving Red avatar created as 'avatar' variable.\n Movement velocity set.");
    // ------------
    //create an opponent - direct method 
    var monster = this.add.rectangle(180, 60, 32, 32, 0x00FF00).setStrokeStyle(5, 0xFF9900);

    This is a config file example to pass into the Phaser.Game. It is a barebones Phaser3 configuration object
    var config = {
            type: graphics_mode,
            width: game_width,
            height: game_height,
            parent: 'div-tag-name',
            scene: [nameOfScene]
        };

    Monitorar alterações em formulário, exibir alteração, filtro por campo.

    Objetivo: 1. Monitorar alterações apenas a parte do formulário contida dentro da DIV "divCheckList". 2. Monitorar alterações apenas os campos que contenham no atributo "for" a palavra (caracteres) "check_". 3. Exibir as alterações em tempo real dentro da div "#parcial".
    var selectElem = document.getElementById('divCheckList') // Seção onde se encontra o form, pode ser o ID da div acima dele ou de alguma div dentro do form.
    selectElem.addEventListener('change', function() {
        $("#parcial").html("");
        $("label").each(function(index, element) {
            var ele = $(element);
            var elementos2 = [];
            algo = ele.attr("for").indexOf("check_"); // aqui filtramos apenas os campos que conteam "check_" no atributo "for", poderia ser ID, Class, placesseholder...
            if (algo > -1) {
                variavel = ("#" + ele.attr("for"));
                elementos2 = [index, ele.html(), ele.attr("for"), $(variavel).val()];
                console.log(elementos2);
                $('#parcial').append("" + elementos2[1] + " - " + elementos2[3] + "\n");

    Simple RPC call

    Simple function to call RPC (only 1k uncompressed). Use this instead of JQuery. Alternatively, use zepto.min.js from zeptojs.com if you have 26K to spare.
