javascript - 我在将值附加到数组时遇到问题

Question

var secretWord = [];
var underScoreWord = [];
// var guesses = [];
var wordLetter = false;

var city = ["Paris", "Wellington", "Hanoi", "Perth", "Marseille", "London", "Ottawa", "Zurich", "Boston", "Tokyo", "Detroit"];

// console.log(city);

// Pick random word from the team array and push the result to an empty array. 
// FUNCTION 1 pick random city
function pickRandomCity() {
    var randomCity = city[Math.floor(Math.random() * city.length)];
    secretWord.push(randomCity);
    return randomCity;
}

var cityPicked = pickRandomCity();

// Get length of secretWord and push as underscores to am empty array
for (var i = 0; i < cityPicked.length; i++) {
underScoreWord.push("_");
}

console.log(secretWord);
console.log(underScoreWord);



// Check for letters
//listen for key press and check to see if its a match
document.onkeyup = function letterCheck(event) {
    var userGuess = event.key;  
  
    for (var j = 0; j < cityPicked.length; j++) {
        if (userGuess === cityPicked[j]) {
            wordLetter = true;
        }
        if (wordLetter) {
        underScoreWord.push(userGuess);
        }
    }



    console.log(wordLetter);
    

}

在 onkeyup 函数中，我试图将结果(按下的键)推送到 theunderScoreWord 数组中。当我键入正确的键时，它正在将 wordLetter bool 值转换为 true，但我无法弄清楚如何将它推到单词内部，所以它显示如下 _ _ N _ _ _

我认为我很接近，但我又可能相距数英里。有什么建议吗？

Answer 1

你想通过 underScoreWord 数组中匹配的单词按下按键来填充 _ 值

示例:

• 如果选择东京作为随机城市，

• 它将存储 [ "_", "_", "_", "_"] 到 underScoreWord

• 现在如果使用 T 它将填充 [ "T", "_", "_", "_"]

• 在使用按下 o 后，它将填充 [ "T", "o", "_", "o"]

Problem :

• secretWord is array but storing entire word in 1 length
• fill data in underScoreWord only the same index of the correct spelling match

请检查以下解决方案:

var secretWord = [];
var underScoreWord = [];
var guesses = [];
var wordLetter = false;

var city = ["Paris", "Wellington", "Hanoi", "Perth", "Marseille", "London", "Ottawa", "Zurich", "Boston", "Tokyo", "Detroit"];

// Pick random word from the team array and push the result to an empty array. 
// FUNCTION 1 pick random city
function pickRandomCity() {
    var randomCity = city[Math.floor(Math.random() * city.length)];
    secretWord  = randomCity.split('');
            
    return randomCity;
}

var cityPicked = pickRandomCity();

// Get length of secretWord and push as underscores to am empty array
for (var i = 0; i < cityPicked.length; i++) {
    underScoreWord.push("_");
}

console.log('secretWord : ' + secretWord);
console.log('underScoreWord : ' + underScoreWord);
console.log('------------------');
console.log('cityPicked : ' + cityPicked);



// Check for letters
//listen for key press and check to see if its a match
document.onkeyup = function letterCheck(event) {
    var userGuess = event.key;
    for (var j = 0; j < secretWord.length; j++) {
        if (userGuess === secretWord[j]) {
            wordLetter = true;
            underScoreWord[j]= userGuess;
        }
    }
    console.log(underScoreWord);
}
