Question

我正在完成一项任务，我必须编写10个随机句子，然后我必须创建文本字段。这些文本字段应该包含我在句子中放入的任何内容。我需要帮助处理包含句子内部单词的代码。我想我已经弄清楚了除了当我输入某些内容时如何输入＆＃34; name＆＃34;它只显示我输入的一个字母而不是整个单词。

这是我的HTML：

<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Assignment 4</title>
<h1> Assignment 4 - Sample Solution </h1>
</head>
<body>
<p>
  Name:         <input type="text" id = "input" value= "names" size="10" />
  <br />

  Verb Phrase:  <input type="text" id = "input2" value="verbs" size="10" />
  <br />

  Adjective:    <input type="text" id = "input3" value="adjs" size="10" />
  <br />

  Noun:         <input type="text" id = "input4" value="nouns" size="10" />
  <br />
HOW MANY SENTENCES? <select id = "numOfSentences" size = "1">

    <option>1</option>
    <option>2</option>
    <option>3</option>
    <option>4</option>
    <option>5</option>
    <option>6</option>
    <option>7</option>
    <option>8</option>
    <option>9</option>
    <option>10</option>
</select>

<button id = "displaySilly">
    Display Silly
</button>
<p id = "output"></p>
<script src = "silly.js"></script>
</body>
</html>

这是我的JS。

//arrays containing values for sentence components
var names = ["Alice","Rowena","Carol","David","Erin"];
var verbs = ["jumped on", "ran from", "scolded", "yelled at","talked to"];
var adjs  = ["yellow","big","smelly","hairy","bad"];
var nouns = ["bear","tree","rock","student","instructor"];

// variables for the sentence components
var name, verb, adj, noun; 

//when window loads
window.onload = function () {
    var names =     document.getElementById("input");
    names.value = null;
    var verbs = document.getElementById("input2");
    verbs.value= null;
    var adjs = document.getElementById("input3");
    adjs.value= null;
    var nouns = document.getElementById("input4");
    nouns.value= null;
}


// display what is put into the text fields in the sentences
//names.push(document.getElementById('input').value);
//verbs.push(document.getElementById('input2').value);
//adjs.push(document.getElementById('input3').value);
//nouns.push(document.getElementById('input4').value);

// display silly sentences 
document.getElementById('displaySilly').onclick = function() {

    var names = document.getElementById("input").value;
    document.getElementById("output").innerHTML = names;

    // get number of sentences from drop down
    var numOfSentences = 
        document.getElementById('numOfSentences').value;
    //convert to integer
    numOfSentences = parseInt(numOfSentences);
    // initialize results string
    var results = "";
    // create required number of silly sentences 
    for (var i = 1 ; i <= numOfSentences ; i++) {
        //pick components at random from arrays 
        name =
            names[Math.floor(Math.random() * names.length)];
        verb =
            verbs[Math.floor(Math.random() * verbs.length)];
        adj =
            adjs[Math.floor(Math.random()  * adjs.length)];
        noun =
            nouns[Math.floor(Math.random() * nouns.length)];
    // concatenate to form a sentence
    // add to other sentences 
    results = results + name + " " + verb +
              " the " + adj  + " " + noun +
              ".<br />";
}


// display the silly sentences 
document.getElementById('output').innerHTML = results;
} //*** END onclick handler

我需要

的帮助

  var names = document.getElementById("input").value;
    document.getElementById("output").innerHTML = names;

谢谢你们

Answer 1

您有不同的变量具有相同的标识符;例如，三个变量称为names。接近结束时，当你用

从数组中读取数据时

names[Math.floor(Math.random() * names.length)];

与包含名称的数组不同names！

所以解决方案是给所有names个不同的名字。
