Question

我使用bootstrap并有一个简单的布局，包括一个按钮。我尝试了here的代码解决方案，但它无效。这是我的代码，它甚至没有显示＆＃39; test＆＃39;点击搜索按钮后。

          "lng": -73.964040
        });

        es.search().then(function (events) {
          console.log(JSON.stringify(events));
          document.getElementById('output').innerHTML = JSON.stringify(events);
        }).catch(function (error) {

Answer 1

使用document.getElementByid（）时，您不需要id之前的#。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!DOCTYPE html>
<html lang="en">

  <meta charset="utf-8">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!-- Die drei oberen meta tags *müssen* zuerst im Head-Tag angegeben werden; alle anderen Tags können anschließend eingefügt werden -->
  <title>Search</title>

  <!-- Bootstrap -->
  <link href="css/bootstrap.min.css" rel="stylesheet">

  <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->

      <![endif]-->

    <div class="container-fluid">
      <h1>Welcome!</h1>
    </br>
    <button id="search" type="button" class="btn btn-primary">Suchen</button>
    <p><br/></p>
    <p id="output"></p>
    </div>
    <script type="text/javascript">
      $('#search').on('click', function (e) {
        document.getElementById('output').innerHTML = "test";
        // I removed the event search code because I do not have the files and it was breaking the example.
      })
    </script>

Answer 2

首先，不要使用＆＃34;＃＆＃34;使用document.getElementById时签名。其次，你需要添加＆＃34;要求＆＃34;参考

检查控制台消息：

＆＃13;

 $('#search').on('click', function (e) {
        document.getElementById('output').innerHTML = "test";

        var EventSearch = require("facebook-events-by-location-core");

        var es = new EventSearch({
          "lat": 40.710803,
          "lng": -73.964040
        });

        es.search().then(function (events) {
          console.log(JSON.stringify(events));
          document.getElementById('output').innerHTML = JSON.stringify(events);
        }).catch(function (error) {
          console.error(JSON.stringify(error));
        }); 
      })

＆＃13;

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div class="container-fluid">
      <h1>Welcome!</h1>
    </br>
    <button id="search" type="button" class="btn btn-primary">Suchen</button>
    <p><br/></p>
    <p id="output"></p>
    </div>

＆＃13;
