我正在做一个作业，我必须随机造出10个句子，并且我必须创建文本字段。这些文本字段应该包括我在句子中输入的内容。我需要帮助的代码，将包括在句子中的话。我想我已经知道了怎么做，除了当我在“name”中键入一些东西时，它只显示我输入的内容的一个字母，而不是整个单词

这是我的HTML：

<!doctype html>
<html>
<head>
<meta charset="UTF-8">

<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>

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

谢谢大家

您有相同标识符的不同变量；例如，三个名为

的变量命名为。接近尾声时，当你用
names[Math.floor（Math.random（）*names.length）]；

这与包含名称的数组不同
因此，解决方案是给所有这些名称
不同的名称。nope很好用。非常感谢。那真的很有帮助。如果需要，可以单击左侧的复选标记，将此问题标记为已回答。否则它将留在未回答的问题列表中！
