javascript - 如何强制唯一单元格在单击时删除其他单元格

Question

请运行代码片段，它可以让您更好地理解我的问题

1. 如您所见，我有一个带有数字的单元格和一个带有符号 (S) 和红色的单元格。
2. 如果我点击任何其他单元格，我的 (S)“UniqueCell”将会移动到那里。
3. 假设我单击编号为 55 的单元格，我的 UniqueCell 将移动到那里，用 (S) 替换 55，现在我单击其他单元格，假设编号为 320 的单元格，我的 UniqueCell 从单元格 55 移动到单元格320，现在我的 UniqueCell 取代了 320，它是(S)，但是 55 号细胞又恢复了它的数量。

我怎样才能防止细胞恢复其数量？一旦我点击它，我怎样才能让它永久失去它的号码？

注意:我正在尝试制作一个游戏，其中玩家 A 选择垂直方向，玩家 B 选择水平方向，因此每次点击绿色都会垂直和水平移动，如果可能的话，我希望每次我点击绿色所在的单元格，如果是垂直的，玩家获得这些分数，如果是水平的，玩家 b 获得分数

var isCol = 0;
var board = [];
for (r = 0; r < 7; r++) {
  var line = [];
  for (c = 0; c < 7; c++) {
    line.push(RandomGenerator(50, 500));
  }
  board.push(line);
}

function prs(curr, c, r) {
  showTable(curr, c, r);
  isCol = (isCol + 1) % 2;
}

function toColor(col, row, chosen_col, chosen_row) {
  var ret = false;
  switch (isCol) {
    case 0:
      if (row == chosen_row) {
        ret = true;
      }
      break;
    case 1:
      if (col == chosen_col) {
        ret = true;
      }
      break;
  }
  return ret;
}

function showTable(c, chosen_col, chosen_row) {
  var str = "";
  str += "<table border=1>";
  for (row = 0; row < 7; row++) {
    str += "<tr>";
    for (let col = 0; col < 7; col++) {
      str += "<td onclick='prs(this, " + col + "," + row + ")'";
      if (toColor(col, row, chosen_col, chosen_row)) {
        if(c.textContent == board[row][col]){
          str += " class=uniqueCell";
        }
        else str += " class='grn' ";
      }
      str += ">";
      if(c.textContent == board[row][col]){
        str += 'S';
      }
      else str += board[row][col];
      str += "</td>";
    }
    str += "</tr>";
  }
  str += "</table>";

  document.getElementById("ff").innerHTML = str;
}

function RandomGenerator(min, max) {
  return Math.floor(Math.random() * (max - min) + min);
}

showTable(-1);

var getUnique = function(){
  var tdElements = document.querySelectorAll('#ff td');
  tdElements[
    RandomGenerator(0, tdElements.length)
  ].classList.add('uniqueCell');
  // update the text of the cell using the class
  document.querySelector('.uniqueCell').textContent = 'S';
};
getUnique();

td{
  border:2px solid black;
  width:10px;
  height:10px;

Answer 1

我们将收集的点保留在对象 P1 和 P2 中，它目前具有点属性 P1.points 和 P2.points

我添加了在 Onclick 中调用的内部 prs() 函数

  $('#turn').text(`Player ${(isCol+1)} turn`);
  if (CellPoint) {
    if (isCol) {P1.points+=CellPoint;}else{P2.points+= CellPoint;}
    $('#p1').text(`Player 1: ${P1.points}`);
    $('#p2').text(`Player 2: ${P2.points}`);
  } else {
    console.log('selected S');
  }

var isCol = 0;
var CellPoint = 0;
var board = [];
var P1 = {
  points: 0
};
var P2 = {
  points: 0
};
for (r = 0; r < 7; r++) {
  var line = [];
  for (c = 0; c < 7; c++) {
    line.push(RandomGenerator(50, 500));
  }
  board.push(line);
}

function prs(curr, c, r) {

  CellPoint = parseInt($(curr).text());

  showTable(curr, c, r);
  isCol = (isCol + 1) % 2;
  clr = isCol ? 'blue' : 'red';
  $(curr).text('S');
  $('#turn').css("color", clr)
    .text(`Player ${(isCol+1)} turn`);
  if (CellPoint) {
    if (isCol) {
      P1.points += CellPoint;
    } else {
      P2.points += CellPoint;
    }
    $('#p1').text(`Player 1: ${P1.points}`);
    $('#p2').text(`Player 2: ${P2.points}`);

  } else {
    console.log('selected S');
  }


}

function toColor(col, row, chosen_col, chosen_row) {
  var ret = false;
  switch (isCol) {
    case 0:
      if (row == chosen_row) {
        ret = true;
      }
      break;
    case 1:
      if (col == chosen_col) {
        ret = true;
      }
      break;
  }
  return ret;
}

function showTable(c, chosen_col, chosen_row) {
  if(c!==-1){board[chosen_row][chosen_col] = 'S';}
  var str = "";
  str += "<table border=1>";
  for (row = 0; row < 7; row++) {
    str += "<tr>";
    for (let col = 0; col < 7; col++) {
      str += "<td onclick='prs(this, " + col + "," + row + ")'";
      
        if(board[row][col]=='S'){
          str += " class=uniqueCell";
        } else{
        if (toColor(col, row, chosen_col, chosen_row)) {
        str += " class='grn' ";} }
     
      str += ">";
      if(board[row][col]=='S') {
        str += 'S';
      } else str += board[row][col];
      str += "</td>";
    }
    str += "</tr>";
  }
  str += "</table>";

  document.getElementById("ff").innerHTML = str;
}

function RandomGenerator(min, max) {
  return Math.floor(Math.random() * (max - min) + min);
}

showTable(-1);

var getUnique = function() {
  var tdElements = document.querySelectorAll('#ff td');
  tdElements[
    RandomGenerator(0, tdElements.length)
  ].classList.add('uniqueCell');
  // update the text of the cell using the class
  document.querySelector('.uniqueCell').textContent = 'S';
};
getUnique();

td {
  border: 2px solid black;
  width: 10px;
  height: 10px;
  text-align: center;
}

td:hover {
  background-color: lightgreen;
}

.grn {
  background-color: green;
  color: white;
}

.turn1 {
  background-color: green;
  color: red;
}

.turn0 {
  background-color: green;
  color: blue;
}

.uniqueCell {
  background-color: tomato;
}
