entityMap|blocks|key|bn7q|text|仔细查看您的代码。在它之前，已经有三个换行符和大量的空格。首先删除这些标记，这样标记之间就不再有换行符。它可能已经做到了这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data^0^^$0|$]|1|@$2|3|4|5|6|7|8|C|9|@]|A|@]|B|$]]]]

Look closely at your code. In it, there are already three line breaks, and a ton of white space before <code>&lt;/textarea&gt;</code>. Remove those first so that there are no line breaks in between the tags any more. It might already do the trick.

Well, everything between <code>&lt;textarea&gt;</code> and <code>&lt;/textarea&gt;</code> is used as the default value for your textarea box. There is some whitespace in your example there. Try to eliminate all of that.

Open (and close!) your PHP tags right after, and before, your <code>textarea</code> tags:

In short: 
<code>&lt;textarea&gt;</code> should be closed immediately on the same line where it started.

General Practice: this will add-up line-breaks and spaces used for indentation in the code.

<pre><code>&lt;textarea id="sitelink" name="sitelink"&gt;
&lt;/textarea&gt;
</code></pre>

Correct Practice

<pre><code>&lt;textarea id="sitelink" name="sitelink"&gt;&lt;/textarea&gt;

entityMap|blocks|key|c3vjl|text|基本上它应该是|type|unstyled|depth|inlineStyleRanges|entityRanges|data|9cmbn|something+here+with+no+spaces+in+the+begining|code-block|syntax|javascript|6mvl3|如果有一些预定义的空格，假设是由于如下所示的代码格式|eeguh|.......

Basically it should be

<pre><code>&lt;textarea&gt;something here with no spaces in the begining&lt;/textarea&gt;
</code></pre>

If there are some predefined spaces lets say due to code formatting like below

<pre><code>&lt;textarea&gt;.......
....some_variable
&lt;/textarea&gt;
</code></pre>

The spaces shown by dots keeps on adding on each submit.

entityMap|blocks|key|db8df|text|文本区域开始标记和结束标记之间的任何空格都将被视为空格。因此，对于上面的代码，正确的方法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|6798c|code-block|syntax|javascript^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|G|9|@]|A|@]|B|$]]|$2|C|4|-4|6|D|8|H|9|@]|A|@]|B|$E|F]]]]

Any space in between textarea openning and closing tags will be consider as whitespace. So for your above code, the correct way will be :

<pre><code>&lt;textarea style="width:350px; height:80px;" cols="42" rows="5" name="sitelink"&gt;&lt;?php if($siteLink_val) echo $siteLink_val; ?&gt;&lt;/textarea&gt;
</code></pre>

entityMap|blocks|key|elnhh|text|另一种变通方法是使用javascript：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|90t6d|//jquery
$('textarea#someid').html($('textarea#someid').html().trim());

//without+jquery
document.getElementById('someid').innerHTML+=+document.getElementById('someid').innerHTML.trim();|code-block|syntax|javascript|84gd6|这就是我所做的。删除代码中的空格和换行符会使代码行过长。^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|J|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|K|9|@]|A|@]|B|$F|G]]|$2|H|4|I|6|7|8|L|9|@]|A|@]|B|$]]]]

Another work around would be to use javascript:

<pre><code>//jquery
$('textarea#someid').html($('textarea#someid').html().trim());

//without jquery
document.getElementById('someid').innerHTML = document.getElementById('someid').innerHTML.trim();
</code></pre>

This is what I did. Removing white-spaces and line-breaks in the code makes the line too long.

entityMap|blocks|key|fm0jj|text|为了让它看起来更简洁，可以考虑使用三元运算符：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|46f62|code-block|syntax|javascript^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|G|9|@]|A|@]|B|$]]|$2|C|4|-4|6|D|8|H|9|@]|A|@]|B|$E|F]]]]

To make it look a bit cleaner, consider using the ternary operator:

I got the same problem, and the solution is very simple: don't start a new line! Although some of the previous answers can solve the problem, the idea is not stated clearly. 
The important understanding is, to get rid of the unintended spaces, never start a new line just after your start tag. 

The following way is WRONG and will leave a lot of unwanted spaces before your text content:

<pre><code> &lt;textarea&gt;
 text content // start with a new line will leave a lot of unwanted spaces
 &lt;/textarea&gt;
</code></pre>

The RIGHT WAY to do it is:

<pre><code> &lt;textarea&gt;text content //put text content right after your start tag, no new line
 &lt;/textarea&gt;
</code></pre>

entityMap|blocks|key|7pcrs|text|一个对我有效的解决方案是添加样式|type|unstyled|depth|inlineStyleRanges|entityRanges|data|f94nm|对于文本区域，因为有时消除所有空格是不可行的(例如，当您希望代码遵守您的编码指南时，需要添加制表符、空格和换行符)|cf7sh|请注意，至少在chrome中，textarea的默认值是：^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|G|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|H|9|@]|A|@]|B|$]]|$2|E|4|F|6|7|8|I|9|@]|A|@]|B|$]]]]

One solution that has worked for me is adding the style <code>white-space: normal;</code> to the textarea because at times it is not feasible to eliminate all the whitespace (for example when you want your code to abide to your coding guidelines which requires adding tabs, whitespaces and line breaks)

Please note that the default for textarea, at least in chrome is:
<code>white-space: pre-wrap;</code>

If you still like to use indentation, do it after opening the <code>&lt;?php</code> tag, like so:

Make sure first that your $siteLink_val isn't returning white space as a value. The &lt;textarea&gt; element by default has an empty value so if the variable you're echo'ing for some reason has spaces, there's your problem right off the bat. 

To make the code the absolute cleanest, I would suggest you could do something like this, allowing for some more flexibility later. I've made a function that returns either a NULL if the variable isn't present (what you seem to be aiming for in the original post) and the absolute value otherwise. Once you've made sure of your variable's contents, try this:

<pre><code>function build_siteLink_val() {
 if ( $siteLink_val ) {
 return $siteLink_val;
 }

 else {
 return "";
 }
}

$output_siteLink_val = build_siteLink_val();
</code></pre>

And the following code in your textarea would now read:

<pre><code>&lt;textarea style="width:350px; height:80px;" cols="42" rows="5" name="sitelink"&gt;&lt;?=$output_siteLink_val?&gt;&lt;/textarea&gt;
</code></pre>

This is assuming your PHP install is configured for short-hand variable calls, as seen in the shortened "&lt;?=?&gt;" tags. If you cannot output this way, remember to preface your PHP code with "&lt;?php" and close with "?&gt;". 

Avoid line breaks between &lt;textarea&gt;'s because it can create the potential of erroneous characters. 

Also, check your CSS to make sure there isn't a padding rule pushing text inward.

Also, you specify a cols and rows value on the textarea, and then style a width and height. These rules are counter-productive, and will result in inconsistent visuals. Stick with either defining the size through style (I recommend giving the element a class) or the rows/cols.

I have a simple <a href="http://www.w3schools.com/TAGS/tag_textarea.asp" rel="noreferrer">text area</a> in a form like this:

<pre><code>&lt;textarea style="width:350px; height:80px;" cols="42" rows="5" name="sitelink"&gt;
 &lt;?php if($siteLink_val) echo $siteLink_val; ?&gt; 
&lt;/textarea&gt;
</code></pre>

I keep getting extra white space in this textarea. When I tab into it my cursor is like in the middle of the textarea and not in the beginning? What is the explanation?

Why is textarea filled with mysterious white spaces?
