javascript - 我不能以角度调用javascript

问题描述

当我以角度运行此代码时，出现错误。

ERROR = Uncaught ReferenceError: openNav 未在 HTMLSpanElement.onclick 中定义 ((index):14)

代码中没有错误，因为当我像这样输入它时它可以工作 onclick="document.getElementById('myNav').style.width = '0%'">×

我从外面把它称为 <script src="my.js" /script> 但我仍然得到同样的错误

我想从脚本中调用函数，我该怎么做？

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<style>
  body {
    font-family: "Lato", sans-serif;
  }

  .overlay {
    height: 100%;
    width: 0;
    position: fixed;
    z-index: 1;
    top: 0;
    left: 0;
    background-color: rgb(0, 0, 0);
    background-color: rgba(0, 0, 0, 0.9);
    overflow-x: hidden;
    transition: 0.5s;
  }

  .overlay-content {
    position: relative;
    top: 25%;
    width: 100%;
    text-align: center;
    margin-top: 30px;
  }

  .overlay a {
    padding: 8px;
    text-decoration: none;
    font-size: 36px;
    color: #818181;
    display: block;
    transition: 0.3s;
  }

  .overlay a:hover,
  .overlay a:focus {
    color: #f1f1f1;
  }

  .overlay .closebtn {
    position: absolute;
    top: 20px;
    right: 45px;
    font-size: 60px;
  }

  @media screen and (max-height: 450px) {
    .overlay a {
      font-size: 20px;
    }
    .overlay .closebtn {
      font-size: 40px;
      top: 15px;
      right: 35px;
    }
  }
</style>
</head>
<body>
<div id="myNav" class="overlay">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()"
    >&times;</a
  >
  <div class="overlay-content">
    <a href="#">About</a>
    <a href="#">Services</a>
    <a href="#">Clients</a>
    <a href="#">Contact</a>
  </div>

<h2>Fullscreen Overlay Nav Example</h2>
<p>
  Click on the element below to open the fullscreen overlay navigation menu.
</p>
<p>
  In this example, the navigation menu will slide in, from left to right:
</p>
<span style="font-size: 30px; cursor: pointer" onclick="openNav()"
  >&#9776; open</span
>

<script>
  function openNav() {
    document.getElementById("myNav").style.width = "100%";
  }

  function closeNav() {
    document.getElementById("myNav").style.width = "0%";
  }
</script>
</body>
</html>
