<p>If you're using jQuery already, you might do something like this:</p>

<pre><code>&lt;textarea cols="50" rows="20" name="text" id="text_id" class="form-control" style="resize:vertical;display:none"&gt;&lt;/textarea&gt;
&lt;button class="show_button"&gt;Show/hide textarea&lt;/button&gt;
&lt;script&gt;$(".show_button").click(function(){$("#text_id").toggle()})&lt;/script&gt;
</code></pre>

<p>This will toggle the textarea for showing</p>

<p>I'm just assuming you're using jQuery, since <code>form-control</code> is used with Bootstrap - That requires jQuery.</p>


blocks|key|2461424|text|你可以使用简单的javascript，甚至jquery。但是对于简单的javascript，你可以这样做:在head部分内的script标签上写道：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2461425|+<script>
function+myFunction()+{
++++document.getElementById("demo").innerHTML+=+"<textarea+cols+=+'50'+rows+=+'20'+name='text'+id='text_id'+class='form-control'+style='resize:vertical'+></textarea>";
}
</script>|code-block|syntax|javascript|2461426|在正文部分：|2461427|<p+id="demo">A+Paragraph.</p>

<p>You can use simple javascript or even jquery. But for simple javascript u can do it like this:
On script tag inside head section write:</p>

<pre><code> &lt;script&gt;
function myFunction() {
    document.getElementById("demo").innerHTML = "&lt;textarea cols = '50' rows = '20' name='text' id='text_id' class='form-control' style='resize:vertical' &gt;&lt;/textarea&gt;";
}
&lt;/script&gt;
</code></pre>

<p>On Body section :</p>

<pre><code>&lt;p id="demo"&gt;A Paragraph.&lt;/p&gt;

&lt;button type="button" onclick="myFunction()"&gt;Click here&lt;/button&gt;
</code></pre>

<pre><code>&lt;textarea cols = '50' rows = '20' name='text' id='text_id' class='form-control' style='resize:vertical; visibility:hidden'&gt; &lt;/textarea&gt;

&lt;button onClick='document.getElementById("text_id").style.visibility = "visible" '&gt; Click me !&lt;/button&gt; 
</code></pre>


blocks|key|5792574|text|这是我能想到的最简洁的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5792575|我们给Textarea一个CSS属性来保持隐藏Display+=+'none‘。一旦按钮被单击，它就会将css属性更改为Display+=+'block‘以使其可见。|5792576|<textarea+cols+=+"50"+rows+=+"20"+name="text"+id="text_id"+class="form-control"+style="resize:vertical;+display+=+'none'"></textarea>
<button+onclick+=+"document.getElementById('text_id').style.display+=+'block'">|code-block|syntax|javascript|5792577|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<p>This is the most compact way you can do this I can think of:</p>
<p>We are giving the Textarea a CSS property to stay hidden Display = 'none'.
Once the button is clicked, it changes that css property to Display = 'block' to make it visible.</p>
<pre><code>&lt;textarea cols = &quot;50&quot; rows = &quot;20&quot; name=&quot;text&quot; id=&quot;text_id&quot; class=&quot;form-control&quot; style=&quot;resize:vertical; display = 'none'&quot;&gt;&lt;/textarea&gt;
&lt;button onclick = &quot;document.getElementById('text_id').style.display = 'block'&quot;&gt;
</code></pre>


<p>I am trying to make a textarea appear when I click on a button because I don't need it to be displayed by itself in my html page.
I'm using something like:</p>

<pre><code>&lt;textarea cols = "50" rows = "20" name="text" id="text_id" class="form-control" style="resize:vertical" &gt;&lt;/textarea&gt;
</code></pre>

<p>But this is not resolving my problem.</p>

<p>Any idea how I can do that?</p>

<p>I actually have two textarea that display the content of existing files, and when I click on a button to show the content in one text area and then click on the second button to show the content of the second textarea, the first textarea becomes empty while I need to keep both contents in both textareas displayed at the same time! How can I do that too?</p>
