如果在用户的浏览器上没有启用JavaScript,是否可以用HTML替换javascript？
我知道我可以使用< noscript>这个显示代替javascript< / noscript>
这工作正常,但它仍然运行JavaScript.
理论上我会想要这个：
如果启用了javascript
运行javascript
如果未启用javascript
不要运行javascript并提供替代方法
我正在使用这个jQuery插件：http://malsup.com/jquery/cycle/int2.html
当我在safari上禁用javascript时,它会显示所有三个项目,都在div中.插件在每个项目中淡入淡出,但如果禁用它,它会连续显示所有三个,而不会像启用javascript一样淡入淡出.
禁用javascript后,我想阻止它同时显示所有三个项目.我会告诉你看起来是什么样的,以及它在JavaScript被禁用时的作用.
禁用视图：http://i42.tinypic.com/212y1j6.png(注意它们3堆叠在彼此的顶部) – 我想阻止它发生,因为JavaScript被禁用

以下是项目所在div的代码：
$(document).ready(function() {
$('#featured-programs-left').cycle({
fx: 'fade',
speed: 'slow',
timeout: 15000,
next: '#next2',
prev: '#prev2'
});
});

解决方法:
有点像Ates’s solution,您可以使用Javascript来更改启用它的用户的内容.例如,假设您有一个花哨的菜单,为Javascript用户提供超级简单的导航,但对非JS用户来说却毫无价值.在HTML中将display属性设置为’none’,然后使用JS启用它.在您的情况下,如果您有不希望为非JS用户显示的内容,则可以默认隐藏它.缺点是如果浏览器关闭JS和CSS,这将无法正常工作.如果您对此感到担心,可以使用JS插入内容.
