One Function interferes with another

What I do when executing a function in javascript, it causes the previous function to start again, not accepting the changes made?

<html>
<script>
    function criartabela() {
        n = document.getElementById("ordem").value;
        a = n * n;
        for (i = 1; i <= a; i++) {
            valor = '' + i;
            conteudo = '<input type="number" id=' + valor + ' value="3"/>';
        }
        var html = "";
        html += '<table border>';
        for (var x = 1; x <= n; x++) {
            html += '<tr>';
            for (var y = 1; y <= n; y++) {
                html += '<td>' + conteudo + '</td>';
            }
            html += '</tr>';
        }
        html += '</table>';
        document.getElementById('diiiv').innerHTML = html;
    }
    function matriz() {
        criartabela();
        termo = [];
        m = '';
        for (i = 1; i <= n; i++) {
            for (j = 1; j <= n; j++) {
                b = document.getElementById("" + valor + "").value;
                termo[i] = '\r\nA' + i + '' + j + '\r\n=' + b + '<br>';
                m = m + termo[i];
            }

        }
        document.getElementById("matriz").innerHTML = m;
    }
</script>
<body>
    <blockquote><blockquote> <!-- 2 tabs -->

    post your code so we can better understand what your real problem is.

    Join the code you have or the functionality you want for the question to be complete and we can help.

  • I’m not sure I understand, but your code is full of implicit global variables, and maybe your problem is a side effect of it. Always declare the variables with var.

From what I understand you want something like this:

function anterior(acao)
{

var data = 'inicio';

if (!executora(acao)) {
   for (var i=0; i<=20; i++) {
     if (i==0) {
         data='';
     }
         data += 'executou '+i+"\n";
   }
 data +='fim';
}
return data;
}

function executora(acao) 
{
 return acao;
}

var saia_anterior = anterior(true);
var saida_posterior = anterior(false);

console.log(saia_anterior+'=======>'+saida_posterior);
