javascript - Uncaught ReferenceError : showTechnical is not defined

Question

我正在尝试添加选项卡，以便当单击它们时，它会显示不同的内容。但是，我收到 3 个控制台错误。两次是加载时，第三次是每次点击技术链接时。页面加载时出现的两个是:

Uncaught Syntaxerror: Unexpected token ILLEGAL
Uncaught TypeError: Cannot call method 'getcontext' of null
Uncaught referenceError: showTechnical is not defined

<小时/>

Javascript:

<script type="text/javascript">
function showTechnical()
{
document.getElementById('container123').value='
<div class="row" id="technical">
<div class="col-md-3">

</div>';
};
</script>

然后，我将 div 称为几行以下:

<div id="container123">
<li><a href="#" onclick="showTechnical()">Technical</a></li>

您正在寻找的是innerHTML或者在 jQuery 中，.html()

不幸的是，你不能像那样多行 JS 字符串，这也会破坏你的代码。

您必须:

• 添加尾随 \对于每一行。但这太乏味了。

  var string = "Some \
                multiline \
                string";
  

• 或者在一行中完成所有操作。但这太困惑了。

• 或者将您拥有的"template"放入 <script> 中其类型不是 text/javascript这会阻止它被解析。 ID 并使用innerHTML 获取内容。干净多了。

  <script type="text/template" id="myTemplate">
    HTML in here
  </script>
  

  您可以使用以下方式检索它们

  var contents = document.getElementById('myTemplate').innerHTML;
  document.getElementById('container123').innerHTML = contents;
  

  或者在 jQuery 中

  var contents = $('#myTemplate');
  $('#container123').html(contents);
