"input type="提交" "不显示为按钮



我正在尝试创建一个基于Web的测验应用程序,其中测验通过表单输入,然后输入到文本文件中。然后,这将分别从文本文件中读取到用户。但是,我的提交按钮无法正常工作,我放了错误吗?然后,想法是通过拨打这些行定义的值来读取文本文件行,并在单独的网页上以无线电格式显示选项。另外,我希望添加一个称为"添加问题"的新按钮,该按钮将问题和3个答案输入文本添加到表单的底部,从而对用户响应。我是否必须使整个表单成为一个函数?

function WriteToFile(passForm) {
  set fso = CreateObject("Scripting.FileSystemObject");
  set s = fso.CreateTextFile(“using theseee / this.txt ", True);
      var year = document.getElementById(‘year’);
      var class = document.getElementById(‘class’);
      var topic = document.getElementById(‘topic’);
      var title = document.getElementById(‘title’);
      var question = document.getElementById(‘question’);
      var option1 = document.getElementById(‘answer1’);
      var option2 = document.getElementById(‘answer2’);
      var option3 = document.getElementById(‘answer3’);
      s.writeline(“Title: " + title);
        s.writeline(“Question: " + question);
          s.writeline(“Option1: " + answer1);
            s.writeline(“Option2: " + answer2);
              s.writeline(“Option3: " + answer3);
                s.writeline("-----------------------------"); s.Close();
              }

您的HTML无效。

表单不能是表元素的孩子,并且输入不能是表行元素的孩子。

只有表单元才能是表行的孩子。

此外,您不能使用 (左双引号)来划界属性值。仅"(引号)或'(postrophe)。

使用验证器。


旁边:解决该问题后,您会发现Scripting.FileSystemObject无法用于Web浏览器。您不能用浏览器侧JS写入任意文件。

您的双重引用是错误的。

这就是:

<input type=“submit” value=“Submit”>

这就是需要的方式:

<input type="submit" value="Submit">

由于双重引用,因此未识别类型,默认情况下输入类型为文本。那就是为什么您遇到这个问题。

您有多个问题。

  • 首先使用正确的引号有助于很多问题。
  • 将您的提交按钮放入TD元素中,以免将其直接放入行中。
  • 您不允许使用class作为JavaScript中的变量名称。

function WriteToFile(passForm) {
    //No Idea what this is. Wont work in snippet
    //set fso = CreateObject("Scripting.FileSystemObject");
    //set s = fso.CreateTextFile(“using theseee / this.txt ", True);
    //use the correct quotes
    var year = document.getElementById('year');
    //it's not allowed to use class as a variable
    var classEl = document.getElementById('class');
    var topic = document.getElementById('topic');
    var title = document.getElementById('title');
    var question = document.getElementById('question');
    var option1 = document.getElementById('answer1');
    var option2 = document.getElementById('answer2');
    var option3 = document.getElementById('answer3');
    //use the correct quotes
    console.log("Title: " + title);
    console.log("Question: " + question);
    console.log("Option1: " + answer1);
    console.log("Option2: " + answer2);
    console.log("Option3: " + answer3);
    console.log("-----------------------------"); s.Close();
