本文介绍了jsFiddle代码在本地计算机上不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使元素在<div>
非常感谢，有人找到了一个解决方案，可以在此处
Thankfully, someone has found a solution which can be found here
但是，当我在本地计算机或服务器上运行该元素时，该元素不会移动.
However, when I run it on my local machine OR on a server, the element does not move.
这是我的源代码:

<style type="text/css">
div.a {
width: 50px;
height:50px;
background-color:red;
position:fixed;
}
</style>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
animateDiv();
});
function makeNewPosition(){
// Get viewport dimensions (remove the dimension of the div)
var h = $(window).height() - 50;
var w = $(window).width() - 50;
var nh = Math.floor(Math.random() * h);
var nw = Math.floor(Math.random() * w);
return [nh,nw];
}
function animateDiv(){
var newq = makeNewPosition();
var oldq = $('.a').offset();
var speed = calcSpeed([oldq.top, oldq.left], newq);
$('.a').animate({ top: newq[0], left: newq[1] }, speed, function(){
animateDiv();
});
};
function calcSpeed(prev, next) {
var x = Math.abs(prev[1] - next[1]);
var y = Math.abs(prev[0] - next[0]);
var greatest = x > y ? x : y;
var speedModifier = 0.1;
var speed = Math.ceil(greatest/speedModifier);
return speed;
}
</script>
</head>
<body>
<div class='a'></div>
</body>
</html>
推荐答案
在Chrome中打开时，出现错误:
Opening in Chrome, I got an error:
Uncaught SyntaxError: Unexpected token ?
在javascript中，大括号后面似乎有一个不可见的字符.用记事本++打开并删除多余的字符.
It looks like there is a non-visible character after the ending brace in the javascript. Open with Notepad++ and delete the extra character.
当您直接从小提琴复制并粘贴时，我已经看到这种情况发生.
I have seen this happen when you copy and paste directly from a fiddle.
