blocks|key|277753|text|当在Javascript中更改元素的display时，在许多情况下，“撤销”element.style.display+=+"none"的结果是element.style.display+=+""。这将从style属性中删除display声明，将display属性的实际值恢复为在文档的样式表中设置的值(如果没有在其他地方重新定义，则恢复为浏览器默认值)。但是更可靠的方法是在CSS中有一个类，比如|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|277754|.invisible+{+display:+none;+}|code-block|syntax|javascript|277755|以及向/从element.className添加/删除这个类名。|277756|entityMap^0|I|7|12|U|20|Q|2U|5|34|7|3F|7|0|0|5|H|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]|$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|11|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|12|8|@$9|13|A|14|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|15|8|@]|D|@]|E|$]]]|N|$]]

When changing element's <code>display</code> in Javascript, in many cases a suitable option to 'undo' the result of <code>element.style.display = "none"</code> is <code>element.style.display = ""</code>. This removes the <code>display</code> declaration from the <code>style</code> attribute, reverting the actual value of <code>display</code> property to the value set in the stylesheet for the document (to the browser default if not redefined elsewhere). But the more reliable approach is to have a class in CSS like

<pre><code>.invisible { display: none; }
</code></pre>

and adding/removing this class name to/from <code>element.className</code>.

blocks|key|277876|text|像Paul解释的那样，在HTML中没有与display相反的文字:+none，因为每个元素都有不同的默认显示，您还可以使用类或内联样式等更改显示。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|277877|然而，如果你使用像jQuery这样的东西，它们的显示和隐藏功能的行为就像是显示无的对立面。当您隐藏元素，然后再次显示该元素时，它将以与隐藏前完全相同的方式显示。它们通过在隐藏元素时存储display属性的旧值来做到这一点，这样当您再次显示它时，它将以隐藏它之前的相同方式显示。https://github.com/jquery/jquery/blob/740e190223d19a114d5373758127285d14d6b71e/src/css.js#L180|offset|length|277878|这意味着，如果您将div设置为display+inline或inline-block，然后将其隐藏，然后再次显示它，它将再次显示为display+inline或inline-block，与以前一样|277879|<div+style="display:inline"+>hello</div>

Like Paul explains there is no literal opposite of display: none in HTML as each element has a different default display and you can also change the display with a class or inline style etc.

However if you use something like jQuery, their show and hide functions behave as if there was an opposite of display none. When you hide, and then show an element again, it will display in exactly the same manner it did before it was hidden. They do this by storing the old value of the display property on hiding of the element so that when you show it again it will display in the same way it did before you hid it.
<a href="https://github.com/jquery/jquery/blob/740e190223d19a114d5373758127285d14d6b71e/src/css.js#L180" rel="nofollow">https://github.com/jquery/jquery/blob/740e190223d19a114d5373758127285d14d6b71e/src/css.js#L180</a>

This means that if you set a div for example to display inline, or inline-block and you hide it and then show it again, it will once again show as display inline or inline-block same as it was before

<pre><code>&lt;div style="display:inline" &gt;hello&lt;/div&gt;
&lt;div style="display:inline-block"&gt;hello2&lt;/div&gt;
&lt;div style="display:table-cell" &gt;hello3&lt;/div&gt;
</code></pre>

script:

<pre><code> $('a').click(function(){
 $('div').toggle();
 });
</code></pre>

Notice that the display property of the div will remain constant even after it was hidden (display:none) and shown again.

blocks|key|61699|text|在打印机友好样式表的情况下，我使用以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|61700|/*+screen+style+*/

In the case of a printer friendly stylesheet, I use the following:

<pre><code>/* screen style */
.print_only { display: none; }

/* print stylesheet */
div.print_only { display: block; }
span.print_only { display: inline; }
.no_print { display: none; }
</code></pre>

I used this when I needed to print a form containing values and the input fields were difficult to print. So I added the values wrapped in a span.print_only tag (div.print_only was used elsewhere) and then applied the .no_print class to the input fields. So on-screen you would see the input fields and when printed, only the values. If you wanted to get fancy you could use JS to update the values in the span tags when the fields were updated but that wasn't necessary in my case. Perhaps not the the most elegant solution but it worked for me!

I ran into this challenge when building an app where I wanted a table hidden for certain users but not for others. 

Initially I set it up as display:none but then display:inline-block for those users who I wanted to see it but I experienced the formatting issues you might expect (columns consolidating or generally messy).

The way I worked around it was to show the table first and then do "display:none" for those users who I didn't want to see it. This way, it formatted normally but then disappeared as needed.

Bit of a lateral solution but might help someone!

visibility:hidden will hide the element but element is their with DOM. And in case of display:none it'll remove the element from the DOM.

So you have option for element to either hide or unhide. But once you delete it ( I mean display none) it has not clear opposite value. display have several values like display:block,display:inline, display:inline-block and many other. you can check it out from W3C.

You can use this <code>display:block;</code> and also add <code>overflow:hidden;</code>

The opposite of <code>visibility: hidden</code> is <code>visibility: visible</code>. Similarly, is there any opposite for <code>display: none</code>?

Many people become confused figuring out how to show an element when it has <code>display: none</code>, since it's not as clear as using the <code>visibility</code> property.

I could just use <code>visibility: hidden</code> instead of <code>display: none</code>, but it does not give the same effect, so I am not going with it.

Is there an opposite to display:none?

jQuery

visibility: hidden的对立面是visibility: visible。同样，display: none也有相反的情况吗？由于元素没有使用visibility属性那么清晰，因此很多人对如何在元素具有display: none时显示元素感到困惑。我可以直接使用visibility: hidden而不是display: none，但它不会产生相同的效果，所以我不会使用它。
