Question

我正在尝试使用jquery创建一个tic tac toe游戏。

这是我的代码：

＆＃13;

td {
  height: 100px;
  width: 50px;
  font-size=30px;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<table border="1">
  <tr>
    <td class="game"></td>
    <td class="game"></td>
    <td class="game"></td>
  </tr>
  <tr>
    <td class="game"></td>
    <td class="game"></td>
    <td class="game"></td>
  </tr>
  <tr>
    <td class="game"></td>
    <td class="game"></td>
    <td class="game"></td>
  </tr>
</table>

＆＃13;

alert

＆＃13;

当玩家获胜时，在将图像放入单元格之前，首先显示alert消息。我想在显示from corenlp import * corenlp = StanfordCoreNLP() corenlp.parse("Every cat loves a dog")消息之前显示图像。我应该怎么做？

Answer 1

在显示警告消息之前，您必须要求代码等待加载图像：

var img = document.createElement("img");
img.src = "file:///c:/NNK/TicTacToe/TicTacToeV1/WebContent/WEB-INF/tictactoeO.jpe";
img.onload = function() { 
    checkIfYouWon();
}
$(this).prepend(img);

checkIfYouWon()功能是您进行胜利测试的地方。这是代码：

$(".game").click(function() {

  var img = document.createElement("img");
  img.onload = function() { 
      checkIfYouWon();
  }
  var col = $(this).index();
  var row = $(this).closest('tr').index();
  if (i % 2 == 0) {
    img.src = "file:///c:/NNK/TicTacToe/TicTacToeV1/WebContent/WEB-INF/tictactoeO.jpe";
    m[row][col] = 'O';
  } else {
    img.src = "file:///c:/NNK/TicTacToe/TicTacToeV1/WebContent/WEB-INF/tictactoeX.jpe";
    m[row][col] = 'X';
  }
  $(this).prepend(img);
  $(this).off();
  i++;
  function checkIfYouWon(){
      var col = $(this).index();
      var row = $(this).closest('tr').index();
      if (i <= 8) {
        if (winhor(row, col)) {
          alert(m[row][col] + " Won!");
          location.reload();
        }
        if (winver(row, col)) {
          alert(m[row][col] + " Won!");
          location.reload();
        }
        if (windiag(row, col)) {
          alert(m[row][col] + " Won!Diag");
          location.reload();
        }
      } else {
        alert("Draw");
        location.reload();
      }
  }
});

Answer 2

您只需等待一段时间然后显示alert()框，您可以setTimeout()使用100ms，例如，查看以下示例：

setTimeout(function(){
  if (winhor(row, col)) {
    alert(m[row][col] + " Won!");
    location.reload();
  }
  if (winver(row, col)) {
    alert(m[row][col] + " Won!");
    location.reload();
  }
  if (windiag(row, col)) {
    alert(m[row][col] + " Won!Diag");
    location.reload();
  }
},100)

希望这有帮助。

$(document).ready(function() {
  i = 0;
  m = new Array(3);
  for (var l = 0; l < 3; l++) {

    for (k = 0; k < 3; k++)
      m[l][k] = null;
  }
});
