对于(var i=0;i您需要在LIKE中使用脚本代码
因为您的脚本是先加载的,但它找不到任何DOM元素,所以无法工作
另外,您不需要包括jquery,因为您的代码中没有使用任何jquery功能,所以可以这样尝试
<!DOCTYPE html>
<html>
<head>
<style>
// your style here
</style>
</head>
<body>
<button id="button">click me</button>
<canvas id="myCanvas" width="500" height="500"></canvas>
<script>
// and no need to include jquery if not used
// you script goes here after adding DOM elements
</script>
</body>
</html>
//你的风格在这里
点击我
//如果不使用jquery,则不需要包含它
//添加DOM元素后,脚本将转到此处
您的html代码在哪个浏览器中不起作用?我也在Fiddle.net上测试了相同的代码,在firefox.firefox版本34中它对我起作用。它在我拥有的三种浏览器中都不起作用。嘿,谢谢它起作用。我怀疑它如何在您的浏览器中起作用而不编写任何其他内容,但它需要额外的代码to在我的工作中。它在删除jQuery脚本后停止工作。因此,我再次包含它,它工作正常。
