javascript - 随机连接四场比赛，不为每列放置第一个冰球

Question

我的问题是我一直在测试每个位置上第一个冰球的位置。

但是当我向左排成一行时，最后三列没有放置任何东西

这意味着他们有 child ，尽管我真的不认为他们有。

我的代码:

var redCheckBox = document.getElementById('redColor');
var yellowCheckBox = document.getElementById('yellowColor');
var easyComputerModeCheckBox = document.getElementById('easy');
var mediumComputerModeCheckBox = document.getElementById('medium');
var hardComputerModeCheckBox = document.getElementById('hard');
var goFirstCheckBox = document.getElementById('first');
var goSecondCheckBox = document.getElementById('goSecond');
var setup = document.getElementById('setup');
var gameBoard = document.getElementById('gameBoard');
var playerDot = document.getElementById('playerDot');
var circleBase = document.getElementsByClassName('circleBase');
var playerColor = '';

function createRedPlayer() {
  playerDot.style.backgroundColor = 'red';
  $(circleBase).hover(function() {
    $(this).css("background-color", "red");
  }, function() {
    $(this).css("background-color", "lightgreen");
  });
}

function createYellowPlayer() {
  playerDot.style.backgroundColor = 'yellow';
  $(circleBase).hover(function() {
    $(this).css("background-color", "yellow");
  }, function() {
    $(this).css("background-color", "lightgreen");
  });
}


function getGameUp() {
  setup.style.display = 'none';
  gameBoard.style.display = 'block';
}

function placeOneForPlayer(x /*where to put it */ ) {
  var node = document.createElement("div");
  node.classList.add("circleBase");
  node.classList.add("type1");
  var randomIdNumber = Math.floor(Math.random() * 2000);
  var idName = "id" + randomIdNumber;
  node.setAttribute("id", idName);
  node.style.backgroundColor = playerDot.style.backgroundColor;
  document.getElementById(x).appendChild(node);
}

function placeOneForEnemy(x /*where to put it */ ) {
  var node = document.createElement("div");
  node.classList.add("circleBase");
  node.classList.add("type1");
  var randomIdNumber = Math.floor(Math.random() * 2000);
  var idName = "id" + randomIdNumber;
  node.setAttribute("id", idName);
  node.style.backgroundColor = enemyDot.style.backgroundColor;
  document.getElementById(x).appendChild(node);
}

function placeColumnOne() {
  if (rowSixOne.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixOne');
  }
}

function placeColumnTwo() {
  if (rowSixTwo.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixTwo');
  }
}

function placeColumnThree() {
  if (rowSixThree.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixThree');
  }
}

function placeColumnFour() {
  if (rowSixFour.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixFour');
  }
}

function placeColumnFive() {
  if (rowSixFour.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixFive');
  }
}

function placeColumnSix() {
  if (rowSixFour.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixSix');
  }
}

function placeColumnSeven() {
  if (rowSixFour.hasChildNodes()) {
    console.log('has child');
  } else {
    placeOneForPlayer('rowSixSeven');

我看到你的问题，在你的 placeColumnFive()、placeColumnSix() 和 placeColumnSeven() 函数中，它们都在比较到第 4 列，而它们应该分别与第 5、6 和 7 列进行比较。所有三个函数都有: if(rowSixFour.hasChildNodes()) .. 请注意 rowSixFour.hasChildNodes 在所有三个函数中。它们应该是 rowSixFive.hasChildNodes、rowSixSix.hasChildNodes 和 rowSixSeven.hasChildNodes。

换句话说:将 placeColumnFive()、placeColumnSix() 和 placeColumnSeven() 函数更改为:

function placeColumnFive(){
  if(rowSixFive.hasChildNodes()){
    console.log('has child');
  }else{
    placeOneForPlayer('rowSixFive');
  }
}

function placeColumnSix(){
  if(rowSixSix.hasChildNodes()){
    console.log('has child');
  }else{
    placeOneForPlayer('rowSixSix');
  }
}

function placeColumnSeven(){
  if(rowSixSeven.hasChildNodes()){
    console.log('has child');
  }else{
    placeOneForPlayer('rowSixSeven');
  }
}
