turnOn Tutorial

Learn how to execute JavaScript functions using the 2sxc turnOn. Extend basic usage by passing data, awaiting conditions and more.

This page activates turnOn and executes a JavaScript function using turnOn.

In this tutorial you'll learn how to:

  • Activate turnOn using the PageService
  • Execute a JavaScript function on initial loading

@inherits Custom.Hybrid.Razor14

<div id="turn-on-basic">
  turnOn is waiting - this will be replaced within 3 seconds... 😔
</div>

@* Executes the JavaScript function window.turnOnTutorial100.init() from the included script file *@
@Kit.Page.TurnOn("window.turnOnTutorial100.init()")

<script src="@App.Path/turnon/use/100-local-js.js" @Kit.Page.AssetAttributes()></script>

// Use an IFFE to ensure the variables are not exposed globaly
// See https://developer.mozilla.org/en-US/docs/Glossary/IIFE
(() => {
  // The init function which should be called
  function init() {
    // Example element gets found in the DOM
    const exampleElement = document.querySelector("#turn-on-basic")
    // Success text gets displayed in the DOM
    exampleElement.innerText = "turnOn has been executed. 😉";
  }
  
  // For demo purpose, wait 3 seconds before we add the object and Init
  // This should simulate slow loading of a JavaScript
  
  setTimeout(() => {
    // Generate a new object if none exists yet (best practice)
    window.turnOnTutorial100 = window.turnOnTutorial100 || {};
    window.turnOnTutorial100.init = window.turnOnTutorial100.init || init;
  }, 3000);
})();

In this page turnOn passes parameters to a JavaScript function. The passed parameters then get deconstructed and used for DOM manipulation.

In this tutorial you'll learn how to:

  • Pass parameters to JavaScript functions using turnOn.
  • Deconstruct passed parameters

    // Example element gets found in the DOM

  const tt = window.turnOnTutorial110 = window.turnOnTutorial110 || {};
  tt.init = tt.init || init;
  tt.demoDeconstruct = tt.demoDeconstruct || demoDeconstruct;
})();

This page creates a unique DOM attribute and sets it on a div. turnOn then passes this attribute to a JavaScript function, which identifies the element with a queryselector and performs DOM manipulations.

In this tutorial you'll learn how to:

  • Create a unique DOM attribute
  • Pass it to a JavaScript function

⬇️ Result | Source ➡️

turnOn hasn't passed any parameters. 
@inherits Custom.Hybrid.Razor14

@{
  // Create unique DOM attribute with Module Id
  var uniqueDomAttribute = "turn-on-example-" + CmsContext.Module.Id;
}

@* Inject attribute into DIV, to make it accessible for query *@
<div @uniqueDomAttribute>
  turnOn hasn't passed any parameters.
</div>


  @* This tutorial uses turnOn, see turnOn tutorials *@

  var data = new {
    domAttribute = uniqueDomAttribute
  };

  // Data gets passed as a single object, so we need to deconstruct it.
  function init({domAttribute}) {
    // The element gets found in the DOM by a querySelector with the passed attribute
    const foundElement = document.querySelector(`[${domAttribute}]`)
    // Parameters get displayed in the DOM
    foundElement.innerText = `turnOn has passed the domAttribute: ${domAttribute}`;
  }
  
  const tt = window.turnOnTutorial111 = window.turnOnTutorial111 || {};
  tt.init = tt.init || init;
})();

This page creates a anonymous object and sets it on a div. turnOn then passes this attribute to a JavaScript function, which identifies the element with a queryselector and performs DOM manipulations.

In this tutorial you'll learn how to:

  • Create a anonymous object in c#
  • Pass it's data to a JavaScript function

⬇️ Result | Source ➡️

@* Inject attribute into DIV, to make it accessible for query *@

  // Create an anonymous object and define example settings 
  var data = new {
    domId = "turn-on-example-complex-object",
    style = new {
      backgroundColor = "mediumpurple",
      height = 100,
      width = 400
    }
  };
}

@* Passes the exampleObject as parameter in a JSON format and executes the window.turnOnTutorial120.init function *@
@Kit.Page.TurnOn("window.turnOnTutorial120.init()", data: data)

  // Data gets passed as a single object, so we need to deconstruct it.
  function init({domId, style}) {
    // The element gets found in the DOM by a querySelector with the passed attribute
    const foundElement = document.querySelector(`#${domId}`)
  
    // apply passed settings on DOM element
    foundElement.style.backgroundColor = style.backgroundColor;
    foundElement.style.height = `${style.height}px`;
    foundElement.style.width = `${style.width}px`;
  
    // Parameters get displayed in the DOM
    foundElement.innerText = `turnOn has passed this data: ${JSON.stringify({domId, style})}`;
  }
  
  const tt = window.turnOnTutorial120 = window.turnOnTutorial120 || {};
  tt.init = tt.init || init;
})();

This waits for a thirdparty library to finish loading, then executes a JavaScript function with turnOn and passes a domAttribute as parameter. The executed JavaScript then triggers thirdparty library code, which modifies the DOM element in the page that causes an animation.

In this tutorial you'll learn how to:

  • Include an external library
  • Execute a JavaScript function after the library has finished loading

⬇️ Result | Source ➡️

@inherits Custom.Hybrid.Razor14

  // Create unique DOM attribute with Module Id
  var domAttribute = "turn-on-require-many-" + CmsContext.Module.Id;

  const tt = window.turnOnTutorial200 = window.turnOnTutorial200 || {};
  tt.init = tt.init || init;
  
  // Example code that consumes thirdparty library
  function animateSpaceship(container) {
    const {Scene, Sprite} = spritejs;
    const scene = new Scene({container, width: 1000, height: 250, mode: 'stickyTop'});
    const layer = scene.layer();
    const spaceShip = new Sprite('https://images.squarespace-cdn.com/content/v1/528a31e5e4b00863f1646510/1562710379584-IOMK7TTBLH7H8GJ8QB1A/Screen+Shot+2019-07-09+at+5.12.37+PM.png');
    
    spaceShip.attr({
      anchor: [0, 0.3],
      pos: [0, 0],

    spaceShip.animate([
      {pos: [0, 0]},
      {pos: [0, 75]},
      {pos: [600, 100]},
      {pos: [600, 50]},

      iterations: Infinity,
      direction: 'alternate',
    });
    
    layer.append(spaceShip);

})();

This waits for a function to return true, then executes a JavaScript function with turnOn and passes a domAttribute as parameter. The executed JavaScript then triggers thirdparty library code, which modifies the DOM element in the page that causes an animation.

In this tutorial you'll learn how to:

  • Execute a JavaScript function after a custom condition was met

This page waits for a system script to load, then executes a JavaScript function with turnOn and passes a domAttribute as parameter. The executed JavaScript then triggers a system script, which binds the fancybox properties.
