Would this be a simple way to write a tabbed function in javascript? If so, how to tag it?

const tabuada = (...args)=>{
    console.log(`Argumentos que foram passados: ${args}`)  
    for (let valor of args) {
        console.log(`${valor} * 2 = ${valor*2} `)
    } 
}
tabuada(1,2,3,4,5)

javascript

  • I don’t understand the question. You want to know how to create your own tag HTML, example: <taboada do="3"></taboada> or you want to know how to put these values within a <div> or <span>?

This code has the following output, assuming that you want to create a table for any number of passings.

function tabuada(...args) {
  for (const number of args) {
    construirTabuada(number);
  }
}

function construirTabuada(numero) {
  let color_td; // apenas para estilizacao.

  document.write("<table border='1px' style='margin: 20px'>"); // comeca a criar uma tabela.

  color_td = "#ccc";
  document.write(`<thead>Tabuada do numero: ${numero}</thead>`); // cria um titulo para a tabela baseado no numero.   
  document.write("<td style='width:30px;background-color: " + color_td + "'>Multiplicando</td>");

  for (let i = 1; i < 10; i++) {
    document.write("<td style='width:30px;background-color: " + color_td + "'>" + i + "</td>");
  }

  document.write("<tr style='height:30px;'>");

  color_td = "#fff";
  document.write("<td style='width:30px;background-color: " + color_td + "'>Resultado</td>");

  for (let j = 1; j < 10; j++) {
    document.write("<td style='width:30px;background-color:" + color_td + "'>" + j * numero + "</td>");
  }

  document.write("</tr>");

  document.write("</table>"); // termina de montar a tabela.
}

tabuada(2, 4, 7); // chamada de teste.

Will produce the following output for the call tabuada(2,4,7), we have the following structure in HTML:

tabuada

Function construirTabuada is responsible for all mathematical logic and for building the table element in HTML. I hope I helped, if that’s the way you wanted it.
