You could split the string on the whitespace and then re-add it, since you know its in between every one of the entries.

<pre><code>var string = "text to split";
 string = string.split(" ");
var stringArray = new Array();
for(var i =0; i &lt; string.length; i++){
 stringArray.push(string[i]);
 if(i != string.length-1){
 stringArray.push(" ");
 }
}
</code></pre>

Update: Removed trailing space.

blocks|key|892015|text|使用regex：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|892016|var+str+++=+"my+car+is+red";

Using regex:

<pre><code>var str = "my car is red";
var stringArray = str.split(/(\s+)/);

console.log(stringArray); // ["my", " ", "car", " ", "is", " ", "red"] 
</code></pre>

<code>\s</code> matches any character that is a whitespace, adding the plus makes it greedy, matching a group starting with characters and ending with whitespace, and the next group starts when there is a character after the whitespace etc.

You can just split on the word boundary using <code>\b</code>. See <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/RegExp#boundaries" rel="noreferrer">MDN</a>

"\b: Matches a zero-width word boundary, such as between a letter and a space."

You should also make sure it is followed by whitespace <code>\s</code>. so that strings like <code>"My car isn't red"</code> still work:

<pre><code>var stringArray = str.split(/\b(\s)/);
</code></pre>

The initial <code>\b</code> is required to take multiple spaces into account, e.g. <code>my car is red</code>

EDIT: Added grouping

Although this is not supported by all browsers, if you use capturing parentheses inside your regular expression then the captured input is spliced into the result.

<blockquote>
 If separator is a regular expression that contains capturing parentheses, then each time separator is matched, the results (including any undefined results) of the capturing parentheses are spliced into the output array. [<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split" rel="noreferrer">reference</a>)
</blockquote>

So:

<pre><code>var stringArray = str.split(/(\s+)/);
 ^ ^
//
</code></pre>

Output:

<pre><code>["my", " ", "car", " ", "is", " ", "red"]
</code></pre>

This collapses consecutive spaces in the original input, but otherwise I can't think of any pitfalls.

For split string by space like in Python lang, can be used:
<pre><code>var w = &quot;hello my brothers ;&quot;;
w.split(/(\s+)/).filter( function(e) { return e.trim().length &gt; 0; } );
</code></pre>
output:
<pre><code>[&quot;hello&quot;, &quot;my&quot;, &quot;brothers&quot;, &quot;;&quot;]
</code></pre>
or similar:
<pre><code>w.split(/(\s+)/).filter( e =&gt; e.trim().length &gt; 0)
</code></pre>
(output some)

In case you're sure you have only one space between two words, you can use this one
<code>str.replace(/\s+/g, ' ').split(' ')</code>
so you replace one space by two, the split by space

blocks|key|870238|text|可以在拆分函数中使用两个空白，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|870239|str.split("++");|code-block|syntax|javascript|870240|这将用空格分隔字符串。|870241|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can use two white space in the split function as below
<pre><code>str.split(&quot; &quot;);
</code></pre>
This will split the string with spaces.

I would like to split a String but I would like to keep white space like:

<pre><code>var str = "my car is red";

var stringArray [];

stringArray [0] = "my";
stringArray [1] = " ";
stringArray [2] = "car";
stringArray [3] = " ";
stringArray [4] = "is";
stringArray [5] = " ";
stringArray [6] = "red";
</code></pre>

How I can proceed to do that?

Thanks !
