He creado un objeto html con el app builder, dentro de este objeto he puesto el siguiente html.

<button id="botontirada" onclick="cartasabajo()" style="font-size:120%"><img src="app/images/inicialgratis.png"></button>

<section id="tirada">

</section>

Se puede acceder al elemento del DOM id=tirada a través de js, ,como sería el código a utilizar para llegar al elemento con id tirada ?.

document.getElementById("tirada");

Gracias

DecSoft

Hola Juan,

Sí; sería posible acceder a dicho elemento tal como dice, incluso, puesto que se cuenta con jQuery, sería posible utilizar esta librería también:


// Esto podría ir en el evento Click de un terminado botón
StartJS
  $('#botontirada').html('Nuevo texto');
EndJS

Hola David, En este ejemplo, el evento del botón va asociado a un función que está creada en un fichero j.s.
cartasabajo()
Este fichero js, que ha incluido en el proyecto, mediante Gestor de archivos F6,
El tema es que el evento no lo reconoce.

Hola Juan,

Habría que ver dónde se define la función "cartasabajo", puesto que, el siguiente código HTML:


<button class="btn btn-md btn-primary" id="my-button" onclick="myCuteFunction(event)">Click here</button>

... funciona como se espera, si "myCuteFunction" está definida en "window", por ejemplo:


window.myCuteFunction = function(event) {
  
  // Show my-button
  alert(event.target.id);
};

... pero también si se define en el "scope" de "window", aunque no se especifique:


var
  myCuteFunction = function(event) {
  
    // Show my-button
    alert(event.target.id);
  };

Note, por otro lado, el evento "onclick" del botón:


<button class="btn btn-md btn-primary" id="my-button" onclick="myCuteFunction(event)">Click here</button>

... parece ser necesario incluir los paréntesis, es decir, esto funciona:


<button class="btn btn-md btn-primary" id="my-button" onclick="myCuteFunction(event)">Click here</button>

<button class="btn btn-md btn-primary" id="my-button" onclick="window.myCuteFunction(event)">Click here</button>

... pero esto otro no funciona como se espera:


<button class="btn btn-md btn-primary" id="my-button" onclick="myCuteFunction">Click here</button>

<button class="btn btn-md btn-primary" id="my-button" onclick="window.myCuteFunction">Click here</button>

Seguramente se trate de los paréntesis, por lo tanto, si es que "cartasabajo" existe en "window", pruebe a poner los paréntesis tal como se refiere arriba.
