Question

该程序应该将您输入的单词放入一个框中，将其分成一个字母数组并随机播放。之后，它将第一个字母大写，并将其余部分小写，并将其输出到同一个框中。

我试图将一个单词拼写成随机字母，但我无法通过此错误。

在Chrome中，它说我有一个意想不到的标识符，在mozilla中它说我错过了newWord = shuffle（newWord）的括号; *固定

编辑：现在我有一个错误，说大写不是一个函数。

<input type="text" id="word">
<input type="button" id="submit" value="Randomize" onclick="Random()">

    word = document.getElementById("word").value
    var n = word.length;

    function Random() {
            for (var start = 0; start < n; start++) {
                var newWord = word.charAT(start)

                    newWord = shuffle(newWord);

                    function shuffle(array) {
                        var currentIndex = array.length,
                            temporaryValue, randomIndex;

                        while (0 !== currentIndex) {

                            randomIndex = Math.floor(Math.random() * currentIndex);
                            currentIndex -= 1;

这一行：

var newWord = (word.charAT(start)

应该是：

var newWord = word.charAt(start)

而且，这是您尝试做的更简化的版本：

＆＃13;

// Get a reference to the DOM element, not a property of the element
// that way you can access another property later without having
// to re-scan the DOM for the element again
var txtWord = document.getElementById("word");
var btn = document.getElementById("submit");

// Set up your events using DOM standards and not inline HTML event attributes
btn.addEventListener("click", random);

// By convention, use camelCase for naming
function random() {

  // Separate all the letters into an array
  var letterArray = txtWord.value.split("");
  
  // create an new array from scrambled letters in the original array
  var scrambledArray = [];
  
  var len = letterArray.length;
  for (var start = 0; start < len; start++) {
    // Get a random number between 0 and the highest array index and put it in the new array
    var num = Math.floor(Math.random() * letterArray.length)
    scrambledArray.push(letterArray[num]);
    
    // Remove letter from original array
    letterArray.splice(num,1);
  }
  console.log(scrambledArray.join(""));
}
