如何隐藏要用jquery切换的元素，同时保持逐步增强 [英] How to hide an element to be toggled with jquery while maintaining progressive enhancement
问题描述
我可以找到的所有答案建议添加display：none to css ...但对于没有javascript的用户，他们将永远不会看到该元素。
All the answers I could find recommended adding display:none to css... but for a user without javascript, they will never see the element.
jQuery(document).ready(function($){
$('#toggleElm').hide();
$('#toggleBtn').click(function(){
$('#shareLink').slideToggle();
})
});
仍会导致元素在网页载入期间出现和消失，因为网页在DOM开始呈现之前
still results in an element that appears and disappears during page load because the page begins rendering before the DOM has finished these days.
<script type='javascript'>
document.write("<style type='text/css'> #toggleElm {display:none} </style>");
</script>
在身体的顶部似乎太黑了。
at the top of the body just seems too hacky.
< html> 元素，然后使用该类来定义元素的样式，与html5样板文件+ modernizr一样
to prevent the javascript FOUC and let your page fully accessible you should apply a .no-js class in <html> element and then use that class to style your elements, exactly as html5 boilerplate+modernizr do
#toggleElm { display: none; }
.no-js #toggleElm { display: block; }
当然，你必须通过javascript在
of course you have to remove that class via javascript soon in the <head> of your document, with a script like this
<script>
(function(d) {
d.className = d.className.replace(/(^|\b)no\-js(\b|$)/, 'js');
}(document.documentElement));
</script>
所以如果javascript被启用，它会把 .no-js class into .js class。
so if javascript is enabled, it will turn the .no-js class into .js class.
使用这种方法，当javascript不可用时，因为在那种情况下，将应用最后的CSS规则，使您的元素可见和可访问。
Using this approach, your page is still accessible even when javascript is not available, because in that scenario the last CSS rule will be applied, leaving your elements visible and accessible.
