What is the best way to test for an empty string with jquery-out-of-the-box?
<p>What is the best way to test for an empty string with jquery-out-of-the-box?</p>

<p>I.e., without plugins. I tried this: </p>

<pre><code>http://zipalong.com/blog/?p=287
</code></pre>

<p>But it did't work at least out-of-the-box. It would be nice to use something that's builtin.</p>

<p>I wouldn't like to repeat </p>

<pre><code>"if (a == null || a=='')"
</code></pre>

<p>everywhere if some  <code>"if (isempty(a))"</code>   would be available.</p>
