Question

我现在有了生成网格的代码。该任务将完成10分钟，例如，并且将要求参与者回答尽可能多的问题。每次他们输入网格中阴影方块数量的答案时，都会出现一个新网格。我目前的问题是，在给出答案后，程序需要评估答案是否正确，并加载新的网格。此过程应重复进行，直到10分钟结束，并且在程序验证答案是否正确后，需要更新正确答案的数量。任务是用PyCharm编辑器编程的，我目前无法让这些序列重复出现，直到为任务设置的时间结束。

代码：

{% block styles %}
<style>

table, tr, td {
  border: 1px solid #000000;
}

.bg-black {
  background-color: #808080;}

</style>
{% endblock styles %}


{% block scripts %}

<script>



var effort_correct, effort_incorrect, effort_attempt, answer;
var matrix = [];



var height = Math.floor((Math.random() * 7) + 5);
var width = Math.floor((Math.random() * 7) + 5);
var gridSize = height * width;
var solution = 0;

    for (var i = 0; i < height; i++) {
        matrix[i] = [];
        for (var j = 0; j < width; j++) {
            if (Math.random() < 0.5) {
                matrix[i][j] = 1;
                solution++;

            } else {
                matrix[i][j] = 0;
            }
        }
    }



function render(grid) {


    var html = '<table><tbody>';
    for (var k = 0; k < height; k++) {
        html += '<tr>';
        for (var l = 0; l < width; l++) {
            html += grid[k][l] ? '<td class="bg-black">&nbsp;&nbsp;&nbsp;&nbsp;</td>' :
                    '<td>&nbsp;</td>';
        }
        html += '</tr>'
    }
    html += '</tbody></table>';
    return html;

}

    document.querySelector('#grid').innerHTML = render(matrix);



function score(answer) {
    if (answer == solution) {
        effort_correct++;
    } else {
        effort_incorrect++;
    }
    effort_attempt++;


}

我用例子创造了一个简单的小提琴，希望它有所帮助： https://jsfiddle.net/ilya_sharonov/wxov81zs/

    var ar = [
      [0,1,0,1],
      [1,0,1,0],
      [0,0,1,1],
      [1,1,0,0],
    ];

function render(arr) {
  var html = '<table><tbody>';
  for (var i=0; i<arr.length; i++) {
    html += '<tr>';
    for (var j=0; j<arr[i].length; j++) {
      html += arr[i][j] ? '<td class="bg-black">&nbsp;&nbsp;&nbsp;&nbsp;</td>':
                          '<td>&nbsp;</td>';
    }
    html += '</tr>'
  }
  html += '</tbody></table>';
  return html;
}

document.querySelector('#grid').innerHTML = render(ar);

在html中显示网格
