Javascript在JSfiddle中工作但在Chrome或IE中没有

标签： javascript html css jsfiddle

我添加了一些javascript来设置登录动画，同时在图片中滑动。

我尝试了JS Fiddle中的代码，它就像一个魅力，但如果我将代码复制粘贴到Chrome或Internet Explorer，则没有任何反应。

两种浏览器都启用了Javascript。

和Javascript：

$(".last").on('click', function() {
  $('li div ul').toggle('');
});
$('.nav > li div ul li a').click(function(e) {
  e.stopPropagation();
});

你必须将你的jQuery代码包装在

中 
$( document ).ready(function() {
  // Your code goes here
});

您可以阅读更多here。通常，只要DOM层次结构已完全构建，脚本就可以运行

所以你的代码将是：

$( document ).ready(function() {
  $(".last").on('click', function() {
    $('li div ul').toggle('');
  });
  $('.nav > li div ul li a').click(function(e) {
    e.stopPropagation();
  });
});

并在头部添加jQuery

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

答案 1 :(得分：1)

我很确定你忘了添加window.onload监听器，因为这是使用JSFiddle执行代码与纯Javascript之间的唯一区别，因为JSFiddle会在加载jQuery时自动执行代码。你应该这样做：

window.addEventListener('load', function(){
    // Your code
});

或者您可以使用jQuery：

$(document).ready(function(){
    // Your code
});
