Question

这对我来说非常棘手（或者我只是愚蠢的）。尝试使用JQuery功能，当用户选择某个单选按钮时，下面的表单会相应更改（例如，个人看到姓名，公司，职位，电话，电子邮件和地址。公司只看到公司，电话，电子邮件和地址。但是目前点击单选按钮没有任何效果。

我还想问： 1）是我的函数$（'＃contactType＆gt; input'）。在正确的地方（在其中）还是应该在其他地方？ 2）我可以使用index.js文件来简化它吗？如果是这样，如何做链接index.js？它只是

干杯。

$(document).ready(function() {
  listenForInputChanges();
})

function listenForInputChanges() {
  $('#contactType >input').change(function() {
    console.log('val is ' + $(this).val())
    switch ($(this).val()) {
      case 'individual':
        $('#nameDiv').show();
        $('#companyDiv').show();
        $('#titleDiv').show();
        $('#phoneDiv').show();
        $('#emailDiv').show();
        $('#addressDiv').show();
        break;

      case 'team':
        $('#nameDiv').show();
        $('#companyDiv').show();
        $('#titleDiv').hide();
        $('#phoneDiv').show();
        $('#emailDiv').show();
        $('#addressDiv').show();
        break;

      case 'company':
        $('#nameDiv').hide();
        $('#companyDiv').show();
        $('#titleDiv').hide();
        $('#phoneDiv').show();
        $('#emailDiv').show();
        $('#addressDiv').show();
        break;
    }
  })
}

你错过了jQuery lib。请务必将其添加到您网页的<head>部分：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

$(document).ready(function() {
  listenForInputChanges();
})

function listenForInputChanges() {
  $('#contactType >input').change(function() {
    console.log('val is ' + $(this).val())
    switch ($(this).val()) {
      case 'individual':
        $('#nameDiv').show();
        $('#companyDiv').show();
        $('#titleDiv').show();
        $('#phoneDiv').show();
        $('#emailDiv').show();
        $('#addressDiv').show();
        break;

      case 'team':
        $('#nameDiv').show();
        $('#companyDiv').show();
        $('#titleDiv').hide();
        $('#phoneDiv').show();
        $('#emailDiv').show();
        $('#addressDiv').show();
        break;

      case 'company':

        $('#titleDiv').hide();

Answer 2

要将JavaScript放在单独的文件中，只需在与.html文件相同的目录中创建一个javascript文件（例如：'index.js'）。之后，将您在该文件中创建的Javascript。现在您可以使用脚本标记包含它：

<h1>
  Sector: Hospitality 
      <span class="slash">/ Year: 2018 
        <span class="slash">/ Review: October 2018
        </span>
      </span>
</h1>

src指向index.js文件相对于.html文件的路径。
